Major new features and changes
|
2017-05-04 12:36:55 +00:00
|
|
|
|
|
2020-09-07 23:01:33 +00:00
|
|
|
|
Noteworthy new features and API
|
|
|
|
|
|
|
|
|
|
Instant playback rate changes
|
|
|
|
|
|
|
|
|
|
Changing the playback rate as quickly as possible so far always required
|
|
|
|
|
a flushing seek. This generally works, but has the disadvantage of
|
|
|
|
|
flushing all data from the playback pipeline and requiring the demuxer
|
|
|
|
|
or parser to do a full-blown seek including resetting its internal state
|
|
|
|
|
and resetting the position of the data source. It might also require
|
|
|
|
|
considerable decoding effort to get to the right position to resume
|
|
|
|
|
playback from at the higher rate.
|
|
|
|
|
|
|
|
|
|
This release adds a new mechanism to achieve quasi-instant rate changes
|
|
|
|
|
in certain playback pipelines without interrupting the flow of data in
|
|
|
|
|
the pipeline. This is activated by sending a seek with the
|
|
|
|
|
GST_SEEK_FLAG_INSTANT_RATE_CHANGE flag and start_type = stop_type =
|
|
|
|
|
GST_SEEK_TYPE_NONE. This flag does not work for all pipelines, in which
|
|
|
|
|
case it is necessary to fall back to sending a full flushing seek to
|
|
|
|
|
change the playback rate. When using this flag, the seek event is only
|
|
|
|
|
allowed to change the current rate and can modify the trickmode flags
|
|
|
|
|
(e.g. keyframe only or not), but it is not possible to change the
|
|
|
|
|
current playback position, playback direction or do a flush.
|
|
|
|
|
|
|
|
|
|
This is particularly useful for streaming use cases like HLS or DASH
|
|
|
|
|
where the streaming download should not be interrupted when changing
|
|
|
|
|
rate.
|
|
|
|
|
|
|
|
|
|
Instant rate changing is handled in the pipeline in a specific sequence
|
|
|
|
|
which is detailed in the seeking design docs. Most elements don’t need
|
|
|
|
|
to worry about this, only elements that sync to the clock need some
|
|
|
|
|
special handling which is implemented in the GstBaseSink base class, so
|
|
|
|
|
should be taken care of automatically in most normal playback pipelines
|
|
|
|
|
and sink elements.
|
|
|
|
|
|
|
|
|
|
See Jan’s GStreamer Conference 2019 talk “Changing Playback Rate
|
|
|
|
|
Instantly” for more information.
|
|
|
|
|
|
|
|
|
|
You can try this feature by passing the -i command line option to
|
|
|
|
|
gst-play-1.0. It is supported at least by qtdemux, tsdemux, hlsdemux,
|
|
|
|
|
and dashdemux.
|
|
|
|
|
|
|
|
|
|
Google Transport-Wide Congestion Control
|
|
|
|
|
|
|
|
|
|
rtpmanager now supports the parsing and generating of RTCP messages for
|
|
|
|
|
the Google Transport-Wide Congestion Control RTP Extension, as described
|
|
|
|
|
in:
|
|
|
|
|
https://tools.ietf.org/html/draft-holmer-rmcat-transport-wide-cc-extensions-01.
|
|
|
|
|
|
|
|
|
|
This “just” provides the required plumbing/infrastructure, it does not
|
|
|
|
|
actually make effect any actual congestion control on the sender side,
|
|
|
|
|
but rather provides information for applications to use to make such
|
|
|
|
|
decisions.
|
|
|
|
|
|
|
|
|
|
See Håvard’s “Google Transport-Wide Congestion Control” talk for more
|
|
|
|
|
information about this feature.
|
|
|
|
|
|
|
|
|
|
GstTranscoder: a new high-level transcoding API for applications
|
|
|
|
|
|
|
|
|
|
The new GstTranscoder library, along with transcodebin and
|
|
|
|
|
uritranscodebin elements, provides high level API for applications to
|
|
|
|
|
transcode media files from one format to another. Watch Thibault’s talk
|
|
|
|
|
“GstTranscoder: A High Level API to Quickly Implement Transcoding
|
|
|
|
|
Capabilities in your Applications” for more information.
|
|
|
|
|
|
|
|
|
|
This also comes with a gst-transcoder-1.0 command line utility to
|
|
|
|
|
transcode one URI into another URI based on the specified encoding
|
|
|
|
|
profile.
|
|
|
|
|
|
|
|
|
|
Active Format Description (AFD) and Bar Data support
|
|
|
|
|
|
|
|
|
|
The GstVideo Ancillary Data API has gained support for Active Format
|
|
|
|
|
Description (AFD) and Bar data.
|
|
|
|
|
|
|
|
|
|
This includes various two new buffer metas: GstVideoAFDMeta and
|
|
|
|
|
GstVideoBarMeta.
|
|
|
|
|
|
|
|
|
|
GStreamer now also parses and extracts AFD/Bar data in the h264/h265
|
|
|
|
|
video parsers, and supports both capturing them and outputting them in
|
|
|
|
|
the decklink elements. See Aaron’s lightning talk at the GStreamer
|
|
|
|
|
Conference for more background.
|
|
|
|
|
|
|
|
|
|
ONVIF trick modes support in both GStreamer RTSP server and client
|
|
|
|
|
|
|
|
|
|
- Support for the various trick modes described in section 6 of the
|
|
|
|
|
ONVIF streaming spec has been implemented in both gst-rtsp-server
|
|
|
|
|
and rtspsrc.
|
|
|
|
|
- Various new properties in rtspsrc must be set to take advantage of
|
|
|
|
|
the ONVIF support
|
|
|
|
|
- Examples are available here: test-onvif-server.c and
|
|
|
|
|
test-onvif-client.c
|
|
|
|
|
- Watch Mathieu Duponchelle’s talk “Implementing a Trickmode Player
|
|
|
|
|
with ONVIF, RTSP and GStreamer” for more information and a live
|
|
|
|
|
demo.
|
|
|
|
|
|
|
|
|
|
GStreamer Codecs library with decoder base classes
|
|
|
|
|
|
|
|
|
|
This introduces a new library in gst-plugins-bad which contains a set of
|
|
|
|
|
base classes that handle bitstream parsing and state tracking for the
|
|
|
|
|
purpose of decoding different codecs. Currently H264, H265, VP8 and VP9
|
|
|
|
|
are supported. These bases classes are meant primarily for internal use
|
|
|
|
|
in GStreamer and are used in various decoder elements in connection with
|
|
|
|
|
low level decoding APIs like DXVA, NVDEC, VAAPI and V4L2 State Less
|
|
|
|
|
decoders. The new library is named gstreamer-codecs-1.0 /
|
|
|
|
|
libgstcodecs-1.0 and is not yet guaranteed to be API stable across major
|
|
|
|
|
versions.
|
|
|
|
|
|
|
|
|
|
MPEG-TS muxing improvements
|
|
|
|
|
|
|
|
|
|
The GStreamer MPEG-TS muxer has seen major improvements on various
|
|
|
|
|
fronts in this cycle:
|
|
|
|
|
|
|
|
|
|
- It has been ported to the GstAggregator base class which means it
|
|
|
|
|
can work in defined-latency mode with live input sources and
|
|
|
|
|
continue streaming if one of the inputs stops producing data.
|
|
|
|
|
|
|
|
|
|
- atscmux, a new ATSC-specific tsmux subclass
|
|
|
|
|
|
|
|
|
|
- Constant Bit Rate (CBR) muxing support via the new bitrate property
|
|
|
|
|
which allows setting the target bitrate in bps. If this is set the
|
|
|
|
|
muxer will insert null packets as padding to achieve the desired
|
|
|
|
|
multiplex-wide constant bitrate.
|
|
|
|
|
|
|
|
|
|
- compliance fixes for TV broadcasting use cases (esp. ATSC). See
|
|
|
|
|
Jan’s talk “TV Broadcast compliant MPEG-TS” for details.
|
|
|
|
|
|
|
|
|
|
- Streams can now be added and removed at runtime: Until now, any
|
|
|
|
|
streams in tsmux had to be present when the element started
|
|
|
|
|
outputting its first buffer. Now they can appear at any point during
|
|
|
|
|
the stream, or even disappear and reappear later using the same PID.
|
|
|
|
|
|
|
|
|
|
- new pcr-interval property allows applications to configure the
|
|
|
|
|
desired interval instead of hardcoding it
|
|
|
|
|
|
|
|
|
|
- basic SCTE-35 support. This is enabled by setting the scte-35-pid
|
|
|
|
|
property on the muxer. Sending SCTE-35 commands is then done by
|
|
|
|
|
creating the appropriate SCTE-35 GstMpegtsSection and sending them
|
|
|
|
|
on the muxer.
|
|
|
|
|
|
|
|
|
|
- MPEG-2 AAC handling improvements
|
|
|
|
|
|
|
|
|
|
New elements
|
|
|
|
|
|
|
|
|
|
- New qmlgloverlay element for rendering a QtQuick scene over the top
|
|
|
|
|
of a video stream. qmlgloverlay requires that Qt support adopting an
|
|
|
|
|
external OpenGL context and is known to work on X11 and Windows.
|
|
|
|
|
Wayland is known not to work due to limitations within Qt. Check out
|
|
|
|
|
the example to see how it works.
|
|
|
|
|
|
|
|
|
|
- The clocksync element is a generic element that can be placed in a
|
|
|
|
|
pipeline to synchronise passing buffers to the clock at that point.
|
|
|
|
|
This is similar to identity sync=true, but because it isn’t
|
|
|
|
|
GstBaseTransform-based, it can process GstBufferLists without
|
|
|
|
|
breaking them into separate GstBuffers. It is also more discoverable
|
|
|
|
|
than the identity option. Note that you do not need to insert this
|
|
|
|
|
element into your pipeline to make GStreamer sync to the pipeline
|
|
|
|
|
clock, this is usually handled automatically by the elements in the
|
|
|
|
|
pipeline (sources and sinks mostly). This element is useful to feed
|
|
|
|
|
non-live input such as local files into elements that expect live
|
|
|
|
|
input such as webrtcbin.`
|
|
|
|
|
|
|
|
|
|
- New imagesequencesrc element to easily create a video stream from a
|
|
|
|
|
sequence of JPEG or PNG images (or any other encoding where the type
|
|
|
|
|
can be detected), basically a multifilesrc made specifically for
|
|
|
|
|
image sequences.
|
|
|
|
|
|
|
|
|
|
- rpicamsrc element for capturing raw or encoded video (H.264, MJPEG)
|
|
|
|
|
from the Raspberry Pi camera. This works much like the popular
|
|
|
|
|
raspivid command line utility but outputs data nicely timestamped
|
|
|
|
|
and formatted in order to integrate nicely with other GStreamer
|
|
|
|
|
elements. Also comes with a device provider so applications can
|
|
|
|
|
discover the camera if available.
|
|
|
|
|
|
|
|
|
|
- aatv and cacatv video filters that transform video ASCII art style
|
|
|
|
|
|
|
|
|
|
- avtp: new Audio Video Transport Protocol (AVTP) plugin for Linux.
|
|
|
|
|
See Andre Guedes’ talk “Audio/Video Bridging (AVB) support in
|
|
|
|
|
GStreamer” for more details.
|
|
|
|
|
|
|
|
|
|
- clockselect: a pipeline element that enables clock selection/forcing
|
|
|
|
|
via gst-launch pipeline syntax.
|
|
|
|
|
|
|
|
|
|
- dashsink: Add new sink to produce DASH content. See Stéphane’s talk
|
|
|
|
|
or blog post for details.
|
|
|
|
|
|
|
|
|
|
- dvbsubenc: a DVB subtitle encoder element
|
|
|
|
|
|
|
|
|
|
- microdns: a libmicrodns-based mdns device provider to discover RTSP
|
|
|
|
|
cameras on the local network
|
|
|

|
|
|
|

|
|
|
|
|
|
|
|
|
- rtmp2: new RTMP client source and sink elements with fully
|
|
|
|
|
asynchronous network operations, better robustness and additional
|
|
|
|
|
features such as handling ping and stats messages, and adobe-style
|
|
|
|
|
authentication. The new rtmp2src and rtmp2sink elements should be
|
|
|
|
|
API-compatible with the old rtmpsrc / rtmpsink elements and should
|
|
|
|
|
work as drop-in replacements.

|
|
|
|
- new RTP source and sink elements to easily set up RTP streaming via
|
|
|
|
|
rtp:// URIs: The rtpsink and rtpsrc elements add an URI interface so
|
|
|
|
|
that streams can be decoded with decodebin using rtp:// URIs. These
|
|
|
|
|
can be used as follows: ``` gst-launch-1.0 videotestsrc ! x264enc !
|
|
|
|
|
rtph264pay config-interval=3 ! rtpsink uri=rtp://239.1.1.1:1234

- svthevcenc: new SVT-HEVC-based H.265 video encoder
|
|
|
|
|
|
|
|
|
|
- switchbin: new helper element which chooses between a set of
|
|
|
|
|
processing chains (paths) based on input caps, and changes the
|
|
|
|
|
active chain if new caps arrive. Paths are child objects, which are
|
|
|
|
|
accessed by the GstChildProxy interface. See the switchbin
|
|
|
|
|
documentation for a usage example.

GStreamer core
|
|
|
|
|
|
|
|
|
|
- filesink: Add a new “full” buffer mode. Previously the default and
|
|
|
|
|
full modes were the same. Now the default mode is like before: it
|
|
|
|
|
accumulates all buffers in a buffer list until the threshold is
|
|
|
|
|
reached and then writes them all out, potentially in multiple
|
|
|
|
|
writes. The new full mode works by always copying memory to a single
|
|
|
|
|
memory area and writing everything out with a single write once the
|
|
|
|
|
threshold is reached.
|
|
|
|
|
|
|
|
|
|
- multiqueue: Add stats property and
|
|
|
|
|
current-level-{buffers, bytes, time} pad properties to query the
|
|
|
|
|
current levels of the corresponding internal queue.
|
|
|
|
|
|
|
|
|
|
Plugins Base
|
|
|
|
|
|
|
|
|
|
- alsa: implement a device provider
|
|
|
|
|
|
|
|
|
|
- alsasrc: added use-driver-timestamp property to force use of
|
|
|
|
|
pipeline timestamps (and disable driver timestamps) if so desired
|
|
|
|
|
|
|
|
|
|
- audioconvert: fix changing the mix-matrix property at runtime
|
|
|
|
|
|
|
|
|
|
- appsrc: added support for segment forwarding or custom GstSegments
|
|
|
|
|
via GstSample, enabled via the handle-segment-change property. This
|
|
|
|
|
only works for segments in TIME format for now.
|
|
|
|
|
|
|
|
|
|
- compositor: various performance optimisations, checkerboard drawing
|
|
|
|
|
fixes, and support for VUYA format
|
|
|
|
|
|
|
|
|
|
- encodebin: Fix and refactor smart encoding; ensure that a single
|
|
|
|
|
segment is pushed into encoders; improve force-key-unit event
|
|
|
|
|
handling.
|
|
|
|
|
|
|
|
|
|
- opusenc: Add low delay option (audio-type=restricted-lowdelay) to
|
|
|
|
|
disable the SILK layer and achieve only 5ms delay.
|
|
|
|
|
|
|
|
|
|
- opusdec: add stats property to retrieve various decoder statistics.
|
|
|
|
|
|
|
|
|
|
- uridecodebin3: Let decodebin3 do its stream selection if no one
|
|
|
|
|
answers
|
|
|
|
|
|
|
|
|
|
- decodebin3: Avoid overriding explicit user selection of streams
|
|
|
|
|
|
|
|
|
|
- playbin: add flag to force use of software decoders over any
|
|
|
|
|
hardware decoders that might also be available
|
|
|
|
|
|
|
|
|
|
- playbin3, playbin: propagate sink context
|
|
|
|
|
|
|
|
|
|
- rawvideoparse: Fix tiling support, allow setting colorimetry
|
|
|
|
|
|
|
|
|
|
- subparse: output plain utf8 text instead of pango-markup formatted
|
|
|
|
|
text if downstream requires it, useful for interop with elements
|
|
|
|
|
that only accept utf8-formatted subtitles such as muxers or closed
|
|
|
|
|
caption converters.
|
|
|
|
|
|
|
|
|
|
- tcpserversrc, tcpclientsrc: add stats property with TCP connection
|
|
|
|
|
stats (some are only available on Linux though)
|
|
|
|
|
|
|
|
|
|
- timeoverlay: add show-times-as-dates, datetime-format and
|
|
|
|
|
datetime-epoch properties to display times with dates
|
|
|
|
|
|
|
|
|
|
- videorate: Fix changing rate property during playback; reverse
|
|
|
|
|
playback fixes; update QoS events taking into account our rate
|
|
|
|
|
|
|
|
|
|
- videoscale: pass through and transform size sensitive metas instead
|
|
|
|
|
of just dropping them
|
|
|
|
|
|
|
|
|
|
Plugins Good
|
|
|
|
|
|
|
|
|
|
- avidemux can handle H.265 video now. Our advice remains to
|
|
|
|
|
immediately cease all contact and communication with anyone who
|
|
|
|
|
hands you H.265 video in an AVI container, however.
|
|
|
|
|
|
|
|
|
|
- avimux: Add support for S24LE and S32LE raw audio and v210 raw video
|
|
|
|
|
formats; support more than 2 channels of raw audio.
|
|
|
|
|
|
|
|
|
|
- souphttpsrc: disable session sharing and cookie jar when the cookies
|
|
|
|
|
property is set; correctly handle seeks past the end of the content
|
|
|
|
|
|
|
|
|
|
- deinterlace: new YADIF deinterlace method which should provide
|
|
|
|
|
better quality than the existing methods and is LGPL licensed;
|
|
|
|
|
alternate fields are supported as input to the deinterlacer as well
|
|
|
|
|
now, and there were also fixes for switching the deinterlace mode on
|
|
|
|
|
the fly.
|
|
|
|
|
|
|
|
|
|
- flvmux: in streamable mode allow adding new pads even if the initial
|
|
|
|
|
header has already been written. Old clients will only process the
|
|
|
|
|
initial stream, new clients will get a header with the new streams.
|
|
|
|
|
The skip-backwards-streams property can be used to force flvmux to
|
|
|
|
|
skip and drop a few buffers rather than produce timestamps that go
|
|
|
|
|
backward and confuse librtmp-based clients. There’s also better
|
|
|
|
|
handling for timestamp rollover when streaming for a long time.
|
|
|
|
|
|
|
|
|
|
- imagefreeze: Add live mode, which can be enabled via the new is-live
|
|
|
|
|
property. In this mode frames will only be output in PLAYING state
|
|
|
|
|
according to the negotiated framerate, skipping frames if the output
|
|
|
|
|
can’t keep up (e.g. because it’s blocked downstream). This makes it
|
|
|
|
|
possible to actually use imagefreeze in live pipelines without
|
|
|
|
|
having to manually ensure somehow that it starts outputting at the
|
|
|
|
|
current running time and without still risking to fall behind
|
|
|
|
|
without recovery.
|
|
|
|
|
|
|
|
|
|
- matroskademux, qtdemux: Provide audio lead-in for some lossy formats
|
|
|
|
|
when doing accurate seeks, to make sure we can actually decode
|
|
|
|
|
samples at the desired position. This is especially important for
|
|
|
|
|
non-linear audio/video editing use-cases.
|
|
|
|
|
|
|
|
|
|
- matroskademux, matroskamux: Handle interlaced field order (tff, bff)
|
|
|
|
|
|
|
|
|
|
- matroskamux:
|
|
|
|
|
|
|
|
|
|
- new offset-to-zero property to offset all streams to start at
|
|
|
|
|
zero. This takes the timestamp of the earliest stream and
|
|
|
|
|
offsets it so that it starts at 0. Some software (VLC,
|
|
|
|
|
ffmpeg-based) does not properly handle Matroska files that start
|
|
|
|
|
at timestamps much bigger than zero, which could happen with
|
|
|
|
|
live streams.
|
|
|
|
|
- added a creation-time property to explicitly set the creation
|
|
|
|
|
time to write into the file headers. Useful when remuxing, for
|
|
|
|
|
example, but also for live feeds where the DateUTC header can be
|
|
|
|
|
set a UTC timestamp corresponding to the beginning of the file.
|
|
|
|
|
- the muxer now also always waits for caps on sparse streams, and
|
|
|
|
|
warns if caps arrive after the header has already been sent,
|
|
|
|
|
otherwise the subtitle track might be silently absent in the
|
|
|
|
|
final file. This might affect applications that send sparse data
|
|
|
|
|
into matroskamux via an appsrc element, which will usually not
|
|
|
|
|
send out the initial caps before it sends out the first buffer.
|
|
|
|
|
|
|
|
|
|
- pulseaudio: device provider improvements: fix discovery of
|
|
|
|
|
newly-added devices and hide the alsa device provider if we provide
|
|
|
|
|
alsa devices
|
|
|
|
|
|
|
|
|
|
- qtdemux: raw audio handling improvements, support for AC4 audio, and
|
|
|
|
|
key-units trickmode interval support
|
|
|
|
|
|
|
|
|
|
- qtmux:
|
|
|
|
|
|
|
|
|
|
- was ported to the GstAggregator base class which allows for
|
|
|
|
|
better handling of live inputs, but might entail minor
|
|
|
|
|
behavioural changes for sparse inputs if inputs are not live.
|
|
|
|
|
- has also gained a force-create-timecode-trak property to create
|
|
|
|
|
a timecode trak in non-mov flavors, which may not be supported
|
|
|
|
|
by Apple but is supported by other software such as Final Cut
|
|
|
|
|
Pro X
|
|
|
|
|
- also a force-chunks property to force the creation of chunks
|
|
|
|
|
even in single-stream files, which is required for Apple ProRes
|
|
|
|
|
certification.
|
|
|
|
|
- also supports 8k resolutions in prefill mode with ProRes.
|
|
|
|
|
|
|
|
|
|
- rtpbin gained a request-jitterbuffer signal which allows
|
|
|
|
|
applications to plug in their own jitterbuffer implementation such
|
|
|
|
|
as the threadsharing jitterbuffer from the Rust plugins, for
|
|
|
|
|
example.
|
|
|
|
|
|
|
|
|
|
- rtprtxsend: add clock-rate-map property to allow generic RTP input
|
|
|
|
|
caps without a clock-rate whilst still supporting the max-size-time
|
|
|
|
|
property for bundled streams.
|
|
|
|
|
|
|
|
|
|
- rtpssrcdemux: introduce max-streams property to guard against
|
|
|
|
|
attacks where the sender changes SSRC for every RTP packet.
|
|
|
|
|
|
|
|
|
|
- rtph264pay, rtph264pay: implement STAP-A and various aggregation
|
|
|
|
|
modes controled by the new aggegrate-mode property: none to not
|
|
|
|
|
aggregate NAL units (as before), zero-latency to aggregate NAL units
|
|
|
|
|
until a VCL or suffix unit is included, or max to aggregate all NAL
|
|
|
|
|
units with the same timestamp (which adds one frame of latency). The
|
|
|
|
|
default has been kept at none for backwards compatibility reasons
|
|
|
|
|
and because various RTP/RTSP implementions don’t handle aggregation
|
|
|
|
|
well. For WebRTC use cases this should be set to zero-latency,
|
|
|
|
|
however.
|
|
|
|
|
|
|
|
|
|
- rtpmp4vpay: add support for config-interval=-1 to resend headers
|
|
|
|
|
with each IDR keyframe, like other video payloaders.
|
|
|
|
|
|
|
|
|
|
- rtpvp8depay: Add wait-for-keyframe property for waiting until the
|
|
|
|
|
next keyframe after packet loss. Useful if the video stream was not
|
|
|
|
|
encoded with error resilience enabled, in which case packet loss
|
|
|
|
|
tends to cause very bad artefacts when decoding, and waiting for the
|
|
|
|
|
next keyframe instead improves user experience considerably.
|
|
|
|
|
|
|
|
|
|
- splitmuxsink and splitmuxsrc can now handle auxiliary video streams
|
|
|
|
|
in addition to the primary video stream. The primary video stream is
|
|
|
|
|
still used to select fragment cut points at keyframe boundaries.
|
|
|
|
|
Auxilliary video streams may be broken up at any packet - so
|
|
|
|
|
fragments may not start with a keyframe for those streams.
|
|
|
|
|
|
|
|
|
|
- splitmuxsink:
|
|
|
|
|
|
|
|
|
|
- new muxer-preset and sink-preset properties for setting
|
|
|
|
|
muxer/sink presets
|
|
|
|
|
- a new start-index property to set the initial fragment id
|
|
|
|
|
- and a new muxer-pad-map property which explicitly maps
|
|
|
|
|
splitmuxsink pads to the muxer pads they should connect to,
|
|
|
|
|
overriding the implicit logic that tries to match pads but
|
|
|
|
|
yields arbitrary names.
|
|
|
|
|
- Also includes the actual sink element in the fragment-opened and
|
|
|
|
|
fragment-closed element messages now, which is especially useful
|
|
|
|
|
for sinks without a location property or when finalisation of
|
|
|
|
|
the fragments is done asynchronously.
|
|
|
|
|
|
|
|
|
|
- videocrop: add support for Y444, Y41B and Y42B pixel formats
|
|
|
|
|
|
|
|
|
|
- vp8enc, vp9enc: change default value of VP8E_SET_STATIC_THRESHOLD
|
|
|
|
|
from 0 to 1 which matches what Google WebRTC does and results in
|
|
|
|
|
lower CPU usage; also added a new bit-per-pixel property to select a
|
|
|
|
|
better default bitrate
|
|
|
|
|
|
|
|
|
|
- v4l2: add support for ABGR, xBGR, RGBA, and RGBx formats and for
|
|
|
|
|
handling interlaced video in alternate fields interlace mode (one
|
|
|
|
|
field per buffer instead of one frame per picture with both fields
|
|
|
|
|
interleaved)
|
|
|
|
|
|
|
|
|
|
- v4l2: Profile and level probing support for H264, H265, MPEG-4,
|
|
|
|
|
MPEG-2, VP8, and VP9 video encoders and decoders
|
|
|
|
|
|
|
|
|
|
Plugins Ugly
|
|
|
|
|
|
|
|
|
|
- asfdemux: extract more metadata: disc number and disc count
|
|
|
|
|
|
|
|
|
|
- x264enc:
|
|
|
|
|
|
|
|
|
|
- respect YouTube bitrate recommendation when user sets the
|
|
|
|
|
YouTube profile preset
|
|
|
|
|
- separate high-10 video formats from 8-bit formats to improve
|
|
|
|
|
depth negotiation and only advertise suitable input raw formats
|
|
|
|
|
for the desired output depth
|
|
|
|
|
- forward downstream colorimetry and chroma-site restrictions to
|
|
|
|
|
upstream elements
|
|
|
|
|
- support more color primaries/mappings
|
|
|
|
|
|
|
|
|
|
Plugins Bad
|
|
|
|
|
|
|
|

this AOMedia AV1 encoder
|
|
|

|
|
|
- decklink: add support for 2K DCI video modes, widescreen NTSC/PAL,
|
|
|
|
|
and for parsing/outputting AFD/Bar data. Also implement a simple
|
|
|
|
|
device provider for Decklink devices.
|
|
|

|
|
|
|
|
|
- dtlsrtpenc: add rtp-sync property which synchronises RTP streams to
|
|
|
|
|
the pipeline clock before passing them to funnel for merging with
|
|
|
|
|
RTCP.
|
|
|
|
|
|
|
|
|
|
- fdkaac: also decode MPEG-2 AAC; encoder now supports more
|
|
|
|
|
multichannel/surround sound layouts
|
|
|
|
|
|
|
|
|
|
- hlssink2: add action signals for custom playlist/fragment handling:
|
|
|
|
|
Instead of always going through the file system API we allow the
|
|
|
|
|
application to modify the behaviour. For the playlist itself and
|
|
|
|
|
fragments, the application can provide a GOutputStream. In addition
|
|
|
|
|
the sink notifies the application whenever a fragment can be
|
|
|
|
|
deleted.
|
|
|
|
|
|
|
|
|
|
- interlace: can now output data in alternate fields mode; added field
|
|
|
|
|
switching mode for 2:2 field pattern
|
|
|
|
|
|
|
|
|
|
- iqa: Add a mode property to enable strict mode that checks that all
|
|
|
|
|
the input streams have the exact same number of frames; also
|
|
|
|
|
implement the child proxy interface
|
|
|
|
|
|
|
|
|
|
- mpeg2enc: add disable-encode-retries property for lower CPU usage
|
|
|
|
|
|
|
|
|
|
- mpeg4videoparse: allow re-sending codec config at IDR via
|
|
|
|
|
config-interval=-1
|
|
|
|
|
|
|
|
|
|
- mpegtsparse: new alignment property to determine number of TS
|
|
|
|
|
packets per output buffer, useful for feeding an MPEG-TS stream for
|
|
|
|
|
sending via udpsink. This can be used in combination with the
|
|
|
|
|
split-on-rai property that makes sure to start a new output buffer
|
|
|
|
|
for any TS packet with the Random Access Indicator set. Also set
|
|
|
|
|
delta unit buffer flag on non-random-access buffers.
|
|
|
|
|
|
|
|
|
|
- mpegdemux: add an ignore-scr property to ignore the SCR in
|
|
|
|
|
non-compliant MPEG-PS streams with a broken SCR, which will work as
|
|
|
|
|
long as PTS/DTS in the PES header is consistently increasing.
|
|
|
|
|
|
|
|
|
|
- tsdemux:
|
|
|
|
|
|
|
|
|
|
- add an ignore-pcr property to ignore MPEG-TS streams with broken
|
|
|
|
|
PCR streams on which we can’t reliably recover correct
|
|
|
|
|
timestamps.
|
|
|
|
|
- new latency property to allow applications to lower the
|
|
|
|
|
advertised worst-case latency of 700ms if they know their
|
|
|
|
|
streams support this (must have timestamps in higher frequency
|
|
|
|
|
than required by the spec)
|
|
|
|
|
- support for AC4 audio
|
|
|
|
|
|
|
|
|
|
- msdk - Intel Media SDK plugin for hardware-accelerated video
|
|
|
|
|
decoding and encoding on Windows and Linux:
|
|
|
|
|
|
|
|
|
|
- mappings for more video formats: Y210, Y410, P012_LE, Y212_LE
|
|
|
|
|
- encoders now support bitrate changes and input format changes in
|
|
|
|
|
playing state
|
|
|
|
|
- msdkh264enc, msdkh265enc: add support for CEA708 closed caption
|

|
|
|
|
|
from ROI metas

|
|
|
|
- msdkh264enc, msdkh265enc: new tune property to enable low-power
|
|
|
|
|
mode
|
|
|
|
|
- msdkh265enc: add support 12-bit 4:2:0 encoding and 8-bit 4:2:2
|
|
|
|
|
encoding and VUYA, Y210, and Y410 as input formats
|
|
|
|
|
- msdkh265enc: add support for screen content coding extension
|
|
|
|
|
- msdkh265dec: add support for main-12/main-12-intra,
|
|
|
|
|
main-422-10/main-422-10-intra 10bit,
|
|
|
|
|
main-422-10/main-422-10-intra 8bit,
|
|
|
|
|
main-422-12/main-422-12-intra, main-444-10/main-444-10-intra,
|
|
|
|
|
main-444-12/main-444-12-intra, and main-444 profiles
|
|
|
|
|
- msdkvp9dec: add support for 12-bit 4:4:4
|
|
|
|
|
- msdkvpp: add support for Y410 and Y210 formats, cropping via
|
|
|
|
|
properties, and a new video-direction property.
|
|
|
|
|
|
|
|
|
|
- mxf: Add support for CEA-708 CDP from S436 essence tracks. mxfdemux
|
|
|
|
|
can now handle Apple ProRes
|
|
|
|
|
|
|
|
|
|
- nvdec: add H264 + H265 stateless codec implementation nvh264sldec
|
|
|
|
|
and nvh265sldec with fewer features but improved latency. You can
|
|
|
|
|
set the environment variable GST_USE_NV_STATELESS_CODEC=h264 to use
|
|
|
|
|
the stateless decoder variant as nvh264dec instead of the “normal”
|
|
|
|
|
NVDEC decoder implementation.
|
|
|
|
|
|
|
|
|
|
- nvdec: add support for 12-bit 4:4:4/4:2:0 and 10-bit 4:2:0 decoding
|
|
|
|
|
|
|
|
|
|
- nvenc:
|
|
|
|
|
|
|
|
|
|
- add more rate-control options, support for B-frame encoding (if
|
|
|
|
|
device supports it), an aud property to toggle Access Unit
|
|
|
|
|
Delimiter insertion, and qp-{min,max,const}-{i,p,b} properties.
|
|
|
|
|
- the weighted-pred property enables weighted prediction.
|
|
|
|
|
- support for more input formats, namely 8-bit and 10-bit RGB
|
|
|
|
|
formats (BGRA, RGBA, RGB10A2, BGR10A2) and YV12 and VUYA.
|
|
|
|
|
- on-the-fly resolution changes are now supported as well.
|
|
|
|
|
- in case there are multiple GPUs on the system, there are also
|
|
|
|
|
per-GPU elements registered now, since different devices will
|
|
|
|
|
have different capabilities.
|
|
|
|
|
- nvh265enc can now support 10-bit YUV 4:4:4 encoding and 8-bit
|
|
|
|
|
4:4:4 / 10-bit 4:2:0 formats up to 8K resolution (with some
|
|
|
|
|
devices). In case of HDR content HDR related SEI nals will be
|
|
|
|
|
inserted automatically.
|
|
|
|
|
|
|
|
|
|
- openjpeg: enable multi-threaded decoding and add support for
|
|
|
|
|
sub-frame encoding (for lower latency)
|
|
|
|
|
|
|
|
|
|
- rtponviftimestamp: add opt-out “drop-out-of-segment” property
|
|
|
|
|
|
|
|
|
|
- spanplc: new stats property
|
|
|
|
|
|
|
|
|
|
- srt: add support for IPv6 and for using hostnames instead of IP
|
|
|
|
|
addresses; add streamid property, but also allow passing the id via
|
|
|
|
|
the stream URI; add wait-for-connection property to srtsink
|
|
|
|
|
|
|
|
|
|
- timecodestamper: this element was rewritten with an updated API
|
|
|
|
|
(properties); it has gained many new properties, seeking support and
|
|
|
|
|
support for linear timecode (LTC) from an audio stream.
|
|
|
|
|
|
|
|
|
|
- uvch264src now comes with a device provider to advertise available
|
|
|
|
|
camera sources that support this interface (mostly Logitech C920s)
|
|
|
|
|
|
|
|
|
|
- wpe: Add software rendering support and support for mouse scroll
|
|
|
|
|
events
|
|
|
|
|
|
|
|
|
|
- x265enc: support more 8/10/12 bits 4:2:0, 4:2:2 and 4:4:4 profiles;
|
|
|
|
|
add support for mastering display info and content light level
|
|
|
|
|
encoding SEIs
|
|
|
|
|
|
|
|
|
|
gst-libav
|
|
|
|
|
|
|
|
|
|
- Add mapping for SpeedHQ video codec used by NDI
|
|
|
|
|
|
|
|
|
|
- Add mapping for aptX and aptX-HD
|
|
|
|
|
|
|
|
|
|
- avivf_mux: support VP9 and AV1
|
|
|
|
|
|
|
|
|
|
- avvidenc: shift output buffer timestamps and output segment by 1h
|
|
|
|
|
just like x264enc does, to allow for negative DTS.
|
|
|
|
|
|
|
|
|
|
- avviddec: Limit default number of decoder threads on systems with
|
|
|
|
|
more than 16 cores, as the number of threads used in avdec has a
|
|
|
|
|
direct impact on the latency of the decoder, which is of as many
|
|
|
|
|
frames as threads, so a large numbers of threads can make for
|
|
|
|
|
latency levels that can be problematic in some applications.
|
|
|
|
|
|
|
|
|
|
- avviddec: Add thread-type property that allows applications to
|
|
|
|
|
specify the preferred multithreading method (auto, frame, slice).
|
|
|
|
|
Note that thread-type=frame may introduce additional latency
|
|
|
|
|
especially in live pipelines, since it introduces a decoding delay
|
|
|
|
|
of number of thread frames.

|
|
|
|
|
2020-09-07 23:01:33 +00:00
|
|
|
|
- The yadif video deinterlacing plugin from gst-plugins-bad, which was
|
|
|
|
|
one of the few GPL licensed plugins, has been removed in favour of
|
|
|
|
|
deinterlace method=yadif.

2020-09-07 23:01:33 +00:00
|
|
|
|
- The avdec_cdgraphics CD Graphics video decoder element from
|
|
|
|
|
gst-libav was never usable in GStreamer and we now have a cdgdec
|
|
|
|
|
element written in Rust in gst-plugins-rs to replace it.
|
|
|
|
|
|
|
|
|
|
- The VDPAU plugin has been unmaintained and unsupported for a very
|
|
|
|
|
long time and does not have the feature set we expect from
|
|
|
|
|
hardware-accelerated video decoders. It’s been superseded by the
|
|
|
|
|
nvcodec plugin leveraging NVIDIA’s NVDEC API.

Miscellaneous API additions

2019-04-18 23:15:21 +00:00
|
|
|
|
|
2020-09-07 23:01:33 +00:00
|
|
|
|
GStreamer core
|
|
|
|
|
|
|
|
|
|
- gst_task_resume(): This new API allows resuming a task if it was
|
|
|
|
|
paused, while leaving it in stopped state if it was stopped or not
|
|
|
|
|
started yet. This can be useful for callback-based driver workflows,
|
|
|
|
|
where you basically want to pause and resume the task when buffers
|
|
|
|
|
are notified while avoiding the race with a gst_task_stop() coming
|
|
|
|
|
from another thread.
|
|
|
|
|
|
|
|
|
|
- info: add printf extensions GST_TIMEP_FORMAT and GST_STIMEP_FORMAT
|
|
|
|
|
for printing GstClockTime/GstClockTimeDiff pointers, which is much
|
|
|
|
|
more convenient to use in debug log statements than the usual
|
|
|
|
|
GST_TIME_FORMAT-followed-by-GST_TIME_ARGS dance. Also add an
|
|
|
|
|
explicit GST_STACK_TRACE_SHOW_NONE enum value.
|
|
|
|
|
|
|
|
|
|
- gst_element_get_current_clock_time() and
|
|
|
|
|
gst_element_get_current_running_time(): new helper functions for
|
|
|
|
|
getting an element clock’s time, and the clock time minus base time,
|
|
|
|
|
respectively. Useful when adding additional input branches to
|
|
|
|
|
elements such as compositor, audiomixer, flvmux, interleave or
|
|
|
|
|
input-selector to determine initial pad offsets and such.
|
|
|
|
|
|
|
|
|
|
- seeking: Add GST_SEEK_FLAG_TRICKMODE_FORWARD_PREDICTED to just skip
|
|
|
|
|
B-frames during trick mode, showing both keyframes + P-frame, and
|
|
|
|
|
add support for it in h264parse and h265parse.
|
|
|
|
|
|
|
|
|
|
- elementfactory: add GST_ELEMENT_FACTORY_TYPE_HARDWARE to allow
|
|
|
|
|
elements to advertise that they are hardware-based or interact with
|
|
|
|
|
hardware. This has multiple applications:
|
|
|
|
|
|
|
|
|
|
- it makes it possible to easily differentiate hardware and
|
|
|
|
|
software based element implementations such as audio or video
|
|
|
|
|
encoders and decoders. This is useful in order to force the use
|
|
|
|
|
of software decoders for specific use cases, or to check if a
|
|
|
|
|
selected decoder is actually hardware-accelerated or not.
|
|
|
|
|
- elements interacting with hardware and their respective drivers
|
|
|
|
|
typically don’t know the actually supported capabilities until
|
|
|
|
|
the element is set into at least READY state and can open a
|
|
|
|
|
device handle and probe the hardware.
|
|
|
|
|
|
|
|
|
|
- gst_uri_from_string_escaped(): identical to gst_uri_from_string()
|
|
|
|
|
except that the userinfo and fragment components of the URI will not
|
|
|
|
|
be unescaped while parsing. This is needed for correctly parsing
|
|
|
|
|
usernames or passwords with : in them .
|
|
|
|
|
|
|
|
|
|
- paramspecs: new GstParamSpec flag GST_PARAM_CONDITIONALLY_AVAILABLE
|
|
|
|
|
to indicate that a property might not always exist.
|
|
|
|
|
|
|
|
|
|
- gst_bin_iterate_all_by_element_factory_name() finds elements in a
|
|
|
|
|
bin by factory name
|
|
|
|
|
|
|
|
|
|
- pad: gst_pad_get_single_internal_link() is a new convenience
|
|
|
|
|
function to return the single internal link of a pad, which is
|
|
|
|
|
useful e.g. to retrieve the output pad of a new multiqueue request
|
|
|
|
|
pad.
|
|
|
|
|
|
|
|
|
|
- datetime: Add constructors to create datetimes with timestamps in
|
|
|
|
|
microseconds, gst_date_time_new_from_unix_epoch_local_time_usecs()
|
|
|
|
|
and gst_date_time_new_from_unix_epoch_utc_usecs().
|
|
|
|
|
|
|
|
|
|
- gst_debug_log_get_lines() gets debug log lines formatted in the same
|
|
|
|
|
way the default log handler would print them
|
|
|
|
|
|
|
|
|
|
- GstSystemClock: Add GST_CLOCK_TYPE_TAI as GStreamer abstraction for
|
|
|
|
|
CLOCK_TAI, to support transmission offloading features where network
|
|
|
|
|
packets are timestamped with the time they are deemed to be actually
|
|
|
|
|
transmitted. Useful in combination with the new AVTP plugin.
|
|
|
|
|
|
|
|
|
|
- miscellaneous utility functions: gst_clear_uri(),
|
|
|
|
|
gst_structure_take().
|
|
|
|
|
|
|
|
|
|
- harness: Added gst_harness_pull_until_eos()
|
|
|
|
|
|
|
|
|
|
- GstBaseSrc:
|
|
|
|
|
|
|
|
|
|
- gst_base_src_new_segment() allows subclasses to update the
|
|
|
|
|
segment to be used at runtime from the ::create() function. This
|
|
|
|
|
deprecates gst_base_src_new_seamless_segment()
|
|
|
|
|
- gst_base_src_negotiate() allows subclasses to trigger format
|
|
|
|
|
renegotiation at runtime from inside the ::create() or ::alloc()
|
|
|
|
|
function
|
|
|
|
|
|
|
|
|
|
- GstBaseSink: new stats property and gst_base_sink_get_stats() method
|
|
|
|
|
to retrieve various statistics such as average frame rate and
|
|
|
|
|
dropped/rendered buffers.
|
|
|
|
|
|
|
|
|
|
- GstBaseTransform: gst_base_transform_reconfigure() is now public
|
|
|
|
|
API, useful for subclasses that need to completely re-implement the
|
|
|
|
|
::submit_input_buffer() virtual method
|
|
|
|
|
|
|
|
|
|
- GstAggregator:
|
|
|
|
|
|
|
|
|
|
- gst_aggregator_update_segment() allows subclasses to update the
|
|
|
|
|
output segment at runtime. Subclasses should use this function
|
|
|
|
|
rather than push a segment event onto the source pad directly.
|
|
|
|
|
- new sample selection API:
|
|
|
|
|
- subclasses should now call gst_aggregator_selected_samples()
|
|
|
|
|
from their ::aggregate() implementation to signal that they
|
|
|
|
|
have selected the next samples they will aggregate
|
|
|
|
|
- GstAggregator will then emit the samples-selected signal
|
|
|
|
|
where handlers can then look up samples per pad via
|
|
|
|
|
gst_aggregator_peek_next_sample().
|
|
|
|
|
- This is useful for example to atomically update input pad
|
|
|
|
|
properties in mixer subclasses such as compositor.
|
|
|
|
|
Applications can now update properties with precise control
|
|
|
|
|
of when these changes will take effect, and for which input
|
|
|
|
|
buffer(s).
|
|
|
|
|
- gst_aggregator_finish_buffer_list() allows subclasses to push
|
|
|
|
|
out a buffer list, improving efficiency in some cases.
|
|
|
|
|
- a ::negotiate() virtual method was added, for consistency with
|
|
|
|
|
other base classes and to allow subclasses to completely
|
|
|
|
|
override the negotiation behaviour.
|
|
|
|
|
- the new ::sink_event_pre_queue() and ::sink_query_pre_queue()
|
|
|
|
|
virtual methods allow subclasses to intercept or handle
|
|
|
|
|
serialized events and queries before they’re queued up
|
|
|
|
|
internally.

GStreamer Plugins Base Libraries
|
|
|
|
|
|
|
|
|
|
Audio library
|
|
|
|
|
|
|
|
|
|
- audioaggregator, audiomixer: new output-buffer-duration-fraction
|
|
|
|
|
property which allows use cases such as keeping the buffers output
|
|
|
|
|
by compositor on one branch and audiomixer on another perfectly
|
|
|
|
|
aligned, by requiring the compositor to output a n/d frame rate, and
|
|
|
|
|
setting output-buffer-duration-fraction to d/n on the audiomixer.
|
|
|
|
|
|
|
|
|
|
- GstAudioDecoder: new max-errors property so applications can
|
|
|
|
|
configure at what point the decoder should error out, or tell it to
|
|
|
|
|
just keep going
|
|
|
|
|
|
|
|
|
|
- gst_audio_make_raw_caps() and gst_audio_formats_raw() are
|
|
|
|
|
bindings-friendly versions of the GST_AUDIO_CAPS_MAKE() C macro.
|
|
|
|
|
|
|
|
|
|
- gst_audio_info_from_caps() now handles encoded audio formats as well
|
|
|
|
|
|
|
|
|
|
PbUtils library
|
|
|
|
|
|
|
|
|
|
- GstEncodingProfile:
|
|
|
|
|
- Do not restrict number of similar profiles in a container
|
|
|
|
|
- add GstValue serialization function
|
|
|
|
|
- codec utils now support more H.264/H.265 profiles/levels and have
|
|
|
|
|
improved extension handling
|
|
|
|
|
|
|
|
|
|
RTP library
|
|
|
|
|
|
|
|
|
|
- rtpbasepayloader: Add scale-rtptime property for scaling RTP
|
|
|
|
|
timestamp according to the segment rate (equivalent to RTSP speed
|
|
|
|
|
parameter). This is useful for ONVIF trickmodes via RTSP.
|
|
|
|
|
|
|
|
|
|
- rtpbasepayload: add experimental property for embedding twcc
|
|
|
|
|
sequencenumbers for Transport-Wide Congestion Control (gated behind
|
|
|
|
|
the GST_RTP_ENABLE_EXPERIMENTAL_TWCC_PROPERTY environment
|
|
|
|
|
variable) - more generic API for enabling this is expected to land
|
|
|
|
|
in the next development cycle.
|
|
|
|
|
|
|
|
|
|
- rtcpbuffer: add RTPFB_TYPE_TWCC for Transport-Wide Congestion
|
|
|
|
|
Control
|
|
|
|
|
|
|
|
|
|
- rtpbuffer: add
|
|
|
|
|
gst_rtp_buffer_get_extension_onebyte_header_from_bytes()``, so that one can parse theGBytes`
|
|
|
|
|
returned by gst_rtp_buffer_get_extension_bytes()
|
|
|
|
|
|
|
|
|
|
- rtpbasedepayload: Add max-reorder property to make the
|
|
|
|
|
previously-hardcoded value when to consider a sender to have
|
|
|
|
|
restarted configurable. In some scenarios it’s particularly useful
|
|
|
|
|
to set max-reorder=0 to disable the behaviour that the depayloader
|
|
|
|
|
will drop packets: when max-reorder is set to 0 all
|
|
|
|
|
reordered/duplicate packets are considered coming from a restarted
|
|
|
|
|
sender.
|
|
|
|
|
|
|
|
|
|
RTSP library
|
|
|
|
|
|
|
|
|
|
- add gst_rtsp_url_get_request_uri_with_control() to create request
|
|
|
|
|
uri combined with control url
|
|
|
|
|
|
|
|
|
|
- GstRTSPConnection: add the possibility to limit the Content-Length
|
|
|
|
|
for RTSP messages via
|
|
|
|
|
gst_rtsp_connection_set_content_length_limit(). The same
|
|
|
|
|
functionality is also exposed in gst-rtsp-server.
|
|
|
|
|
|
|
|
|
|
SDP library
|
|
|
|
|
|
|
|
|
|
- add support for parsing the extmap attribute from caps and storing
|
|
|
|
|
inside caps The extmap attribute allows mapping RTP extension header
|
|
|
|
|
IDs to well-known RTP extension header specifications. See RFC8285
|
|
|
|
|
for details.
|
|
|
|
|
|
|
|
|
|
Tags library
|
|
|
|
|
|
|
|
|
|
- update to latest iso-code and support more languages
|
|
|
|
|
|
|
|
|
|
- add tags for acoustid id & acoustid fingerprint, plus MusicBrainz ID
|
|
|
|
|
handling fixes
|
|
|
|
|
|
|
|
|
|
Video library
|
|
|
|
|
|
|
|
|
|
- High Dynamic Range (HDR) video information representation and
|
|
|
|
|
signalling enhancements:
|
|
|
|
|
|
|
|
|
|
- New APIs for HDR video information representation and
|
|
|
|
|
signalling:
|
|
|
|
|
- GstVideoMasteringDisplayInfo: display color volume info as
|
|
|
|
|
per SMPTE ST 2086
|
|
|
|
|
- GstVideoContentLightLevel: content light level specified in
|
|
|
|
|
CEA-861.3, Appendix A.
|
|
|
|
|
- plus functions to serialise/deserialise and add them to or
|
|
|
|
|
parse them from caps
|
|
|
|
|
- gst_video_color_{matrix,primaries,transfer}_{to,from}_iso():
|
|
|
|
|
new utilility functions for conversion from/to ISO/IEC
|
|
|
|
|
23001-8
|
|
|
|
|
- add ARIB STD-B67 transfer chracteristic function
|
|
|
|
|
- add SMPTE ST 2084 support and BT 2100 colorimetry
|
|
|
|
|
- define bt2020-10 transfer characteristics for clarity:
|
|
|
|
|
bt707, bt2020-10, and bt2020-12 transfer characteristics are
|
|
|
|
|
functionally identical but have their own unique values in
|
|
|
|
|
the specification.
|
|
|
|
|
- h264parse, h265parse: Parse mastering display info and content
|
|
|
|
|
light level from SEIs.
|
|
|
|
|
- matroskademux: parse HDR metadata
|
|
|
|
|
- matroskamux: Write MasteringMetadata and Max{CLL,FALL}. Enable
|
|
|
|
|
muxing with HDR meta data if upstream provided it
|
|
|
|
|
- avviddec: Extract HDR information if any and map bt2020-10, PQ
|
|
|
|
|
and HLG transfer functions
|
|
|
|
|
|
|
|
|
|
- added bt601 transfer function (for completeness)
|
|
|
|
|
|
|
|
|
|
- support for more pixel formats:
|
|
|
|
|
|
|
|
|
|
- Y412 (packed 12 bits 4:4:4:4)
|
|
|
|
|
- Y212 (packed 12 bits 4:2:2)
|
|
|
|
|
- P012 (semi-planar 4:2:0)
|
|
|
|
|
- P016_{LE,BE} (semi-planar 16 bits 4:2:0)
|
|
|
|
|
- Y444_16{LE,BE} (planar 16 bits 4:4:4)
|
|
|
|
|
- RGB10A2_LE (packed 10-bit RGB with 2-bit alpha channel)
|
|
|
|
|
- NV12_32L32 (NV12 with 32x32 tiles in linear order)
|
|
|
|
|
- NV12_4L4 (NV12 with 4x4 tiles in linear order)
|
|
|
|
|
|
|
|
|
|
- GstVideoDecoder:
|
|
|
|
|
|
|
|
|
|
- new max-errors property so applications can configure at what
|
|
|
|
|
point the decoder should error out, or tell it to just keep
|
|
|
|
|
going
|
|
|
|
|
|
|
|
|
|
- new qos property to disable dropping frames because of QoS, and
|
|
|
|
|
post QoS messages on the bus when dropping frames. This is
|
|
|
|
|
useful for example in a scenario where the decoded video is
|
|
|
|
|
tee-ed off to go into a live sink that syncs to the clock in one
|
|
|
|
|
branch, and an encoding and save to file pipeline in the other
|
|
|
|
|
branch. In that case one wouldn’t want QoS events from the video
|
|
|
|
|
sink make the decoder drop frames because that would also leave
|
|
|
|
|
gaps in the encoding branch then.
|
|
|
|
|
|
|
|
|
|
- GstVideoEncoder:
|
|
|
|
|
|
|
|
|
|
- gst_video_encoder_finish_subframe() is new API to push out
|
|
|
|
|
subframes (e.g. slices), so encoders can split the encoding into
|
|
|
|
|
subframes, which can be useful to reduce the overall end-to-end
|
|
|
|
|
latency as we no longer need to wait for the full frame to be
|
|
|
|
|
encoded to start decoding or sending out the data.
|
|
|
|
|
- new min-force-key-unit-interval property allows configuring the
|
|
|
|
|
minimum interval between force-key-unit requests and prevents a
|
|
|
|
|
big bitrate increase if a lot of key-units are requested in a
|
|
|
|
|
short period of time (as might happen in live streaming RTP
|
|
|
|
|
pipelines when packet loss is detected).
|
|
|
|
|
- various force-key-unit event handling fixes
|
|
|
|
|
|
|
|
|
|
- GstVideoAggregator, compositor, glvideomixer: expose
|
|
|
|
|
max-last-buffer-repeat property on pads. This can be used to have a
|
|
|
|
|
compositor display either the background or a stream on a lower
|
|
|
|
|
zorder after a live input stream freezes for a certain amount of
|
|
|
|
|
time, for example because of network issues.
|
|
|
|
|
|
|
|
|
|
- gst_video_format_info_component() is new API to find out which
|
|
|
|
|
components are packed into a given plane, which is useful to prevent
|
|
|
|
|
us from assuming a 1-1 mapping between planes and components.
|
|
|
|
|
|
|
|
|
|
- gst_video_make_raw_caps() and gst_video_formats_raw() are
|
|
|
|
|
bindings-friendly versions of the GST_VIDEO_CAPS_MAKE() C macro.
|
|
|
|
|
|
|
|
|
|
- video-blend: Add support for blending on top of 16 bit per component
|
|
|
|
|
formats, which makes sure we can support every currently supported
|
|
|
|
|
raw video format for blending subtitles or logos on top of video.
|
|
|
|
|
|
|
|
|
|
- GST_VIDEO_BUFFER_IS_TOP_FIELD() and
|
|
|
|
|
GST_VIDEO_BUFFER_IS_BOTTOM_FIELD() convenience macros to check
|
|
|
|
|
whether the video buffer contains only the top field or bottom field
|
|
|
|
|
of an interlaced picture.
|
|
|
|
|
|
|
|
|
|
- GstVideoMeta now includes an alignment field with the
|
|
|
|
|
GstVideoAlignment so buffer producers can explicitly specify the
|
|
|
|
|
exact geometry of the planes, allowing users to easily know the
|
|
|
|
|
padded size and height of each plane. Default values will be used if
|
|
|
|
|
this is not set.
|
|
|
|
|
|
|
|
|
|
Use gst_video_meta_set_alignment() to set the alignment and
|
|
|
|
|
gst_video_meta_get_plane_size() or gst_video_meta_get_plane_height()
|
|
|
|
|
to compute the plane sizes or plane heights based on the information
|
|
|
|
|
in the video meta.
|
|
|
|
|
|
|
|
|
|
- gst_video_info_align_full() works like gst_video_info_align() but
|
|
|
|
|
also retrieves the plane sizes.
|
|
|
|
|
|
|
|
|
|
MPEG-TS library
|
|
|
|
|
|
|
|
|
|
- support for SCTE-35 sections
|
|
|
|
|
|
|
|
|
|
- extend support for ATSC tables:
|
|
|
|
|
|
|
|
|
|
- System Time Table (STT)
|
|
|
|
|
- Master Guide Table (MGT)
|
|
|
|
|
- Rating Region Table (RRT)

Miscellaneous performance, latency and memory optimisations
|
2019-01-17 01:38:59 +00:00
|
|
|
|
|
|
|
|
|
As always there have been many performance and memory usage improvements
|
2020-06-19 18:13:36 +00:00
|
|
|
|
across all components and modules. Some of them have already been
|
|
|
|
|
mentioned elsewhere so won’t be repeated here.
|
2019-01-17 01:38:59 +00:00
|
|
|
|
|
|
|
|
|
The following list is only a small snapshot of some of the more
|
|
|
|
|
interesting optimisations that haven’t been mentioned in other contexts
|
|
|
|
|
yet:
|
|
|
|
|
|
2020-09-07 23:01:33 +00:00
|
|
|
|
- caps negotiation, structure and GValue performance optimizations
|
|
|
|
|
|
|
|
|
|
- systemclock: clock waiting performance improvements (moved from
|
|
|
|
|
GstPoll to GCond for waiting), especially on Windows.
|
|
|
|
|
|
|
|
|
|
- rtpsession: add support for buffer lists on the recv path for better
|
|
|
|
|
performance with higher packet rate streams.
|
|
|
|
|
|
|
|
|
|
- rtpjitterbuffer: internal timer handling has been rewritten for
|
|
|
|
|
better performance, see Nicolas’ talk “Revisiting RTP Jitter Buffer
|
|
|
|
|
Timers” for more details.
|
|
|
|
|
|
|
|
|
|
- H.264/H.265 parsers and RTP payloaders/depayloaders have been
|
|
|
|
|
optimised for latency to make sure data is processed and pushed out
|
|
|
|
|
as quickly as possible
|
|
|
|
|
|
|
|
|
|
- video-scaler: correctness and performance improvements, esp. for
|
|
|
|
|
interlaced formats and GBRA
|
|
|
|
|
|
|
|
|
|
- GstVideoEncoder has gained new API to push out subframes
|
|
|
|
|
(e.g. slices), so encoders can split the encoding into subframes,
|
|
|
|
|
which can be useful to reduce the overall end-to-end latency as we
|
|
|
|
|
no longer need to wait for the full frame to be encoded to start
|
|
|
|
|
decoding or sending out the data.
|
|
|
|
|
|
|
|
|
|
This is complemented by the new GST_VIDEO_BUFFER_FLAG_MARKER which
|
|
|
|
|
is a video-specific buffer flag to mark the end of a video frame, so
|
|
|
|
|
elements can know that they have received all data for a frame
|
|
|
|
|
without waiting for the beginning of the next frame. This is similar
|
|
|
|
|
to how the RTP marker flag is used in many RTP video mappings.
|
|
|
|
|
|
|
|
|
|
The video encoder base class now also releases the internal stream
|
|
|
|
|
lock before pushing out data, so as to not block the input side of
|
|
|
|
|
things from processing more data in the meantime.
|
|
|
|
|
|
|
|
|
|
Miscellaneous other changes and enhancements
|
|
|
|
|
|
|
|
|
|
- it is now possible to modify the initial rank of plugin features
|
|
|
|
|
without modifying the source code or writing code to do so
|
|
|
|
|
programmatically via the GST_PLUGIN_FEATURE_RANK environment
|
|
|
|
|
variable. Users can adjust the rank of plugin(s) by passing a
|
|
|
|
|
comma-separated list of feature:rank pairs where rank can be a
|
|
|
|
|
numerical value or one of NONE, MARGINAL, SECONDARY, PRIMARY, and
|
|
|
|
|
MAX. Example: GST_PLUGIN_FEATURE_RANK=myh264dec:MAX,avdec_h264:NONE
|
|
|
|
|
sets the rank of the myh264dec element feature to the maximum and
|
|
|
|
|
that of avdec_h264 to 0 (none), thus ensuring that myh264dec is
|
|
|
|
|
prefered as H264 decoder in an autoplugging context.
|
|
|
|
|
|
|
|
|
|
- GstDeviceProvider now does a static probe on start as fallback for
|
|
|
|
|
providers that don’t support dynamic probing to make things easier
|
|
|
|
|
for users
|
|
|
|
|
|
|
|
|
|
WebRTC
|
|
|
|
|
|
|
|
|
|
- webrtcbin now contains initial support for renegotiation involving
|
|
|
|
|
stream addition and removal. There are a number of caveats to this
|
|
|
|
|
initial renegotiation support and many complex scenarios are known
|
|
|
|
|
to require some work.
|
|
|
|
|
|
|
|
|
|
- webrtcbin now exposes the internal ICE object for advanced
|
|
|
|
|
configuration options. Using the internal ICE object, it is possible
|
|
|
|
|
to toggle UDP or TCP connection usage as well as provide local
|
|
|
|
|
network addresses.
|
2017-05-04 12:36:55 +00:00
|
|
|
|
|
2020-09-07 23:01:33 +00:00
|
|
|
|
- Fix a number of call flows within webrtcbin’s GstPromise handling
|
|
|
|
|
where a promise was never replied to. This has been fixed and now a
|
|
|
|
|
promise will always receive a reply.
|
2017-05-04 12:36:55 +00:00
|
|
|
|
|
2020-09-07 23:01:33 +00:00
|
|
|
|
- webrtcbin now exposes a latency property for configuring the
|
|
|
|
|
internal rtpjitterbuffer latency and buffering when receiving
|
|
|
|
|
streams.
|
2017-05-04 12:36:55 +00:00
|
|
|
|
|
2020-09-07 23:01:33 +00:00
|
|
|
|
- webrtcbin now only synchronises the RTP part of a stream, allowing
|
|
|
|
|
RTCP messages to skip synchronisation entirely.
|
2018-03-13 19:08:54 +00:00
|
|
|
|
|
2020-09-07 23:01:33 +00:00
|
|
|
|
- Fixed most of the webrtcbin state properties (connection-state,
|
|
|
|
|
ice-connection-state, signaling-state, but not ice-gathering-state
|
|
|
|
|
as that requires newer API in libnice and will be fixed in the next
|
|
|
|
|
release series) to advance through the state values correctly. Also
|
|
|
|
|
implemented DTLS connection states in the DTLS elements so that
|
|
|
|
|
peer-connection-state is not always new.
|
|
|
|
|
|
|
|
|
|
- webrtcbin now accounts for the a=ice-lite attribute in a remote SDP
|
|
|
|
|
offer and will configure the internal ICE implementation
|
|
|
|
|
accordingly.
|
|
|
|
|
|
|
|
|
|
- webrtcbin will now resolve .local candidate addresses using the
|
|
|
|
|
system DNS resolver. .local candidate addresses are now produced by
|
|
|
|
|
web browsers to help protect the privacy of users.
|
|
|
|
|
|
|
|
|
|
- webrtcbin will now add candidates found in the SDP to the internal
|
|
|
|
|
ICE agent. This was previously unsupported and required using the
|
|
|
|
|
add-ice-candidate signal manually from the application.
|
|
|
|
|
|
|
|
|
|
- webrtcbin will now correctly parse a TURN URI that contains a
|
|
|
|
|
username or password with a : in it.
|
|
|
|
|
|
|
|
|
|
- The GStreamer WebRTC library gained a GstWebRTCDataChannel object
|
|
|
|
|
roughly matching the interface exposed by the WebRTC specification
|
|
|
|
|
to allow for easier binding generation and use of data channels.

GStreamer OpenGL bindings/build related changes
|
|
|
|
|
|
|
|
|
|
- The GStreamer OpenGL library (libgstgl) now ships pkg-config files
|
|
|
|
|
for platform-specific API where libgstgl provides a public
|
|
|
|
|
integration interface and a pkg-config file for a dependency on the
|
|
|
|
|
detected OpenGL headers. The new list of pkg-config files in
|
|
|
|
|
addition to the original gstreamer-gl-1.0 are gstreamer-gl-x11-1.0,
|
|
|
|
|
gstreamer-gl-wayland-1.0, gstreamer-gl-egl-1.0, and
|
|
|
|
|
gstreamer-gl-prototypes-1.0 (for OpenGL headers when including
|
|
|
|
|
gst/gl/gstglfuncs.h).
|
|
|
|
|
|
|
|
|
|
- GStreamer OpenGL now ships some platform-specific introspection data
|
|
|
|
|
for platforms that have a public interface. This should allow for
|
|
|
|
|
easier integration with bindings involving platform specific
|
|
|
|
|
functionality. The new introspection data files are named
|
|
|
|
|
GstGLX11-1.0, GstGLWayland-1.0, and GstGLEGL-1.0.
|
|

GStreamer OpenGL Features
|
|
|
|
|
|
|
|
|
|
- The iOS implementation no longer accesses UIKit objects off the main
|
|
|
|
|
thread fixing a loud warning message when used in iOS applications.
|
|
|
|
|
|
|
|
|
|
- Support for mouse and keyboard handling using the GstNavigation
|
|
|
|
|
interface was added for the wayland implementation complementing the
|
|
|
|
|
already existing support for the X11 and Windows implementations.
|
|
|
|
|
|
|
|
|
|
- A new helper base class for source elements, GstGLBaseSrc is
|
|
|
|
|
provided to ease writing source elements producing OpenGL video
|
|
|
|
|
frames.
|
|
|
|
|
|
|
|
|
|
- Support for some more 12-bit and 16-bit video formats (Y412_LE,
|
|
|
|
|
Y412_BE, Y212_LE, Y212_BE, P012_LE, P012_BE, P016, NV16, NV61) was
|
|
|
|
|
added to glcolorconvert.
|
|
|
|
|
|
|
|
|
|
- glupload can now import dma-buf’s into external-oes textures.
|
|
|
|
|
|
|
|
|
|
- A new display type for EGLDevice-based systems was added. It is
|
|
|
|
|
currently opt-in by using either the GST_GL_PLATFORM=egl-device
|
|
|
|
|
environment variable or manual construction
|
|
|
|
|
(gst_gl_display_egl_device_new*()) due to compatibility issues with
|
|
|
|
|
some platforms.
|
|
|
|
|
|
|
|
|
|
- Support was added for WinRT/UWP using the ANGLE project for running
|
|
|
|
|
OpenGL-based pipelines within a UWP application.
|
|
|
|
|
|
|
|
|
|
- Various elements now support changing the GstGLDisplay to be used at
|
|
|
|
|
runtime in simple cases. This is primarily helpful for changing or
|
|
|
|
|
adding an OpenGL-based video sink that must share an OpenGL context
|
|
|
|
|
with an external source to an already running pipeline.
|
|
|
|
|
|
|
|
|
|
GStreamer Vulkan integration
|
|
|
|
|
|
|
|
|
|
- There is now a GStreamer Vulkan library to provide integration
|
|
|
|
|
points and helpers with applications and external GStreamer Vulkan
|
|
|
|
|
based elements. The structure of the library is modelled similarly
|
|
|
|
|
to the already existing GStreamer OpenGL library. Please note that
|
|
|
|
|
the API is still unstable and may change in future releases,
|
|
|
|
|
particularly around memory handling. The GStreamer Vulkan library
|
|
|
|
|
contains objects for sharing the vkInstance, vkDevice, vkQueue,
|
|
|
|
|
vkImage, VkMemory, etc with other elements and/or the application as
|
|
|
|
|
well as some helper objects for using Vulkan in an application or
|
|
|
|
|
element.
|
|
|
|
|
|
|
|
|
|
- Added support for building and running on/for the Android and
|
|
|
|
|
Windows systems to complement the existing XCB, Wayland, MacOS, and
|
|
|
|
|
iOS implementations.
|
|
|
|
|
|
|
|
|
|
- XCB gained support for mouse/keyboard events using the GstNavigation
|
|
|
|
|
API.
|
|
|
|
|
|
|
|
|
|
- New vulkancolorconvert element for converting between color formats.
|
|
|
|
|
vulkancolorconvert can currently convert to/from all 8-bit RGBA
|
|
|
|
|
formats as well as 8-bit RGBA formats to/from the YUV formats AYUV,
|
|
|
|
|
NV12, and YUY2.
|
|
|
|
|
|
|
|
|
|
- New vulkanviewconvert element for converting between stereo view
|
|
|
|
|
layouts. vulkanviewconvert can currently convert between all of the
|
|
|
|
|
single memory formats (side-by-side, top-bottom, column-interleaved,
|
|
|
|
|
row-interleaved, checkerboard, left, right, mono).
|
|
|
|
|
|
|
|
|
|
- New vulkanimageidentity element for a blit from the input vulkan
|
|
|
|
|
image/s to a new vulkan image/s.
|
|
|
|
|
|
|
|
|
|
- The vulkansink element can now scale the input image to the output
|
|
|
|
|
window/surface size where that information is available.
|
|
|
|
|
|
|
|
|
|
- The vulkanupload element can now configure a transfer from system
|
|
|
|
|
memory to VulkanImage-based memory. Previously, this required two
|
|
|
|
|
vulkanupload elements.

Tracing framework and debugging improvements
|
2017-05-04 12:36:55 +00:00
|
|
|
|
|
2020-09-07 23:01:33 +00:00
|
|
|
|
- gst_tracing_get_active_tracers() returns a list of active tracer
|
|
|
|
|
objects. This can be used to interact with tracers at runtime using
|
|
|
|
|
GObject API such as action signals. This has been implemented in the
|
|
|
|
|
leaks tracer for snapshotting and retrieving leaked/active objects
|
|
|
|
|
at runtime.
|
|
|
|
|
|
|
|
|
|
- The leaks tracer can now be interacted with programmatically at
|
|
|
|
|
runtime via GObject action signals:
|
|
|
|
|
|
|
|
|
|
- get-live-object returns a list of live (allocated) traced
|
|
|
|
|
objects
|
|
|
|
|
- log-live-objects logs a list of live objects into the debug log.
|
|
|
|
|
This is the same as sending the SIGUSR1 signal on unix systems,
|
|
|
|
|
but works on all operating systems including Windows.
|
|
|
|
|
- activity-start-tracking, activity-get-checkpoint,
|
|
|
|
|
activity-log-checkpoint, activity-stop-tracking: add support for
|
|
|
|
|
tracking and checkpointing objects, similar to what was
|
|
|
|
|
previously available via SIGUSR2 on unix systems, but works on
|
|
|
|
|
all operating systems including Windows.
|
|
|
|
|
|
|
|
|
|
- various GStreamer gdb debug helper improvements:
|
|
|
|
|
|
|
|
|
|
- new ‘gst-pipeline-tree’ command
|
|
|
|
|
- more gdb helper functions: gst_element_pad(), gst_pipeline() and
|
|
|
|
|
gst_bin_get()
|
|
|
|
|
- support for queries and buffers
|
|
|
|
|
- print more info for segment events, print event seqnums, object
|
|
|
|
|
pointers and structures
|
|
|
|
|
- improve gst-print command to show more pad and element
|
|
|
|
|
information

|
|
gst-launch-1.0
|
|
|
|
|
|
|
|
|
|
- now prints the pipeline position and duration if available when the
|
|
|
|
|
pipeline is advancing. This is hopefully more user-friendly and
|
|
|
|
|
gives visual feedback on the terminal that the pipeline is actually
|
|
|
|
|
up and running. This can be disabled with the --no-position command
|
|
|
|
|
line option.
|
|
|
|
|
|
|
|
|
|
- the parse-launch pipeline syntax now has support for presets:
|
|
|
|
|
use@preset=<preset-name>" after an element to load a preset.
|
|
|
|
|
|
|
|
|
|
gst-inspect-1.0
|
|
|
|
|
|
|
|
|
|
- new --color command line option to force coloured output even if not
|
|
|
|
|
connected to a tty
|
|
|
|
|
|
|
|
|
|
gst-tester-1.0 (new)
|
|
|
|
|
|
|
|
|
|
- gst-tester-1.0 is a new tool for plugin developers to launch
|
|
|
|
|
.validatetest files with TAP compatible output, meaning it can
|
|
|
|
|
easily and cleanly be integrated with the meson test harness. It
|
|
|
|
|
allows you to use gst-validate (from the gst-devtools module) to
|
|
|
|
|
write integration tests in any GStreamer repository whilst keeping
|
|
|
|
|
the tests as close as possible to the code. The tool transparently
|
|
|
|
|
handles gst-validate being installed or not: if it is not installed
|
|
|
|
|
those integration tests will simply be skipped.
|
|
|
|
|
|
|
|
|
|
gst-play-1.0
|
|
|
|
|
|
|
|
|
|
- interactive keyboard controls now also work on Windows
|
|
|
|
|
|
|
|
|
|
gst-transcoder-1.0 (new)
|
|
|
|
|
|
|
|
|
|
- gst-transcoder-1.0 is a new command line tool to transcode one URI
|
|
|
|
|
into another URI based on the specified encoding profile using the
|
|
|
|
|
new GstTranscoder API (see above).

GStreamer RTSP server
|
2017-05-04 12:36:55 +00:00
|
|
|
|
|
2020-09-07 23:01:33 +00:00
|
|
|
|
- Fix issue where the first few packets (i.e. keyframes) could
|
|
|
|
|
sometimes be dropped if the rtsp media pipeline had a live input.
|
|
|
|
|
This was a regression from GStreamer 1.14. There are more fixes
|
|
|
|
|
pending for that which will hopefully land in 1.18.1.
|
|
|
|
|
|
|
|
|
|
- Fix backpressure handling when sending data in TCP interleave mode
|
|
|
|
|
where RTSP requests and responses and RTP/RTCP packets flow over the
|
|
|
|
|
same RTSP TCP connection: The previous implementation would at some
|
|
|
|
|
point stop sending data to other clients when a single client
|
|
|
|
|
stopped consuming data or did not consume data fast enough. This
|
|
|
|
|
obviously created problems for shared media, where the same stream
|
|
|
|
|
from a single producer pipeline is sent to multiple clients. Instead
|
|
|
|
|
we now manage a backlog in the server’s stream-transport component
|
|
|
|
|
and remove slow clients once this backlog exceeds a maximum duration
|
|
|
|
|
(which is currently hardcoded).
|
|
|
|
|
|
|
|
|
|
- Onvif Streaming Specification trick modes support (see section at
|
|
|
|
|
the beginning)
|
|
|
|
|
|
|
|
|
|
- Scale/Speed header support: Speed will deliver the data at the
|
|
|
|
|
requested speed, which means increasing the data bandwidth for
|
|
|
|
|
speeds > 1.0. Scale will attempt to do the same without affecting
|
|
|
|
|
the overall bandwidth requirement vis-a-vis normal playback speed
|
|
|
|
|
(e.g. it might drop data for fast-forward playback).
|
|
|
|
|
|
|
|
|
|
- rtspclientsink: send buffer lists in one go for better performance

GStreamer VAAPI
|
2017-05-04 12:36:55 +00:00
|
|
|
|
|
2020-09-07 23:01:33 +00:00
|
|
|
|
- A lot of work was done adding support for media-driver (iHD), the
|
|
|
|
|
new VAAPI driver for Intel, mostly for Gen9 onwards.
|
|
|
|
|
|
|
|
|
|
- Available color formats and frame sizes are now detected at run-time
|
|
|
|
|
according to the context configuration.
|
|
|
|
|
|
|
|
|
|
- Gallium drivers have been re-enabled in the allowed drivers list
|
|
|
|
|
|
|
|
|
|
- Improved the mapping between VA formats and GStreamer formats by
|
|
|
|
|
generating a mapping table at run-time since even among different
|
|
|
|
|
drivers the mapping might be different, particularly for RGB with
|
|
|
|
|
little endianness.
|
|
|
|
|
|
|
|
|
|
- The experimental Flexible Encoding Infrastructure (FEI) elements
|
|
|
|
|
have been removed since they were not really actively maintained or
|
|
|
|
|
tested.
|
|
|
|
|
|
|
|
|
|
- Enhanced the juggling of DMABuf buffers and VASurface metas
|
|
|
|
|
|
|
|
|
|
- New vaapioverlay element: a compositor element using VA VPP blend
|
|
|
|
|
capabilities to accelerate overlaying and compositing. Example
|
|
|
|
|
pipeline:
|
|
|
|
|
|
|
|
|
|
gst-launch-1.0 -vf videotestsrc ! vaapipostproc ! tee name=testsrc ! queue \
|
|
|
|
|
! vaapioverlay sink_1::xpos=300 sink_1::alpha=0.75 name=overlay ! vaapisink \
|
|
|
|
|
testsrc. ! queue ! overlay.
|
|
|
|
|
|
|
|
|
|
vaapipostproc
|
|
|
|
|
|
|
|
|
|
- added video-orientation support, supporting frame mirroring and
|
|
|
|
|
rotation
|
|
|
|
|
|
|
|
|
|
- added cropping support, either via properties (crop-left,
|
|
|
|
|
crop-right, crop-bottom and crop-top) or buffer meta.
|
|
|
|
|
|
|
|
|
|
- new skin-tone-enhancenment-level property which is the iHD
|
|
|
|
|
replacement of the i965 driver’s sink-tone-level. Both are
|
|
|
|
|
incompatible with each other, so both were kept.
|
|
|
|
|
|
|
|
|
|
- handle video colorimetry
|
|
|
|
|
|
|
|
|
|
- support HDR10 tone mapping
|
|
|
|
|
|
|
|
|
|
vaapisink
|
|
|
|
|
|
|
|
|
|
- resurrected wayland backend for non-weston compositors by extracting
|
|
|
|
|
the DMABuf from the VASurface and rendering it.
|
|
|
|
|
|
|
|
|
|
- merged the video overlay API for wayland. Now applications can
|
|
|
|
|
define the “window” to render on.
|
|
|
|
|
|
|
|
|
|
- demoted the vaapisink element to secondary rank since libva
|
|
|
|
|
considers rendering as a second-class feature.
|
|
|
|
|
|
|
|
|
|
VAAPI Encoders
|
|
|
|
|
|
|
|
|
|
- new common target-percentage property which is the desired target
|
|
|
|
|
percentage of bitrate for variable rate control.
|
|
|
|
|
|
|
|
|
|
- encoders now extract their caps from the driver at registration
|
|
|
|
|
time.
|
|
|
|
|
|
|
|
|
|
- vaapivp9enc: added support for low power mode and support for
|
|
|
|
|
profile 2 (profile 0 by default)
|
|
|
|
|
|
|
|
|
|
- vaapih264enc: new max-qp property that sets the maximum quantization
|
|
|
|
|
value. Support for ICQ and QBVR bitrate control mode, adding a
|
|
|
|
|
quality-factor property for these modes. Support baseline profile as
|
|
|
|
|
constrained-baseline
|
|
|
|
|
|
|
|
|
|
- vaapih265enc:
|
|
|
|
|
|
|
|
|
|
- support for main-444 and main-12 encoding profiles.
|
|
|
|
|
- new max-qp property that sets the maximum quantization value.
|
|
|
|
|
- support for ICQ and QBVR bitrate control mode, adding a
|
|
|
|
|
quality-factor property for these modes.
|
|
|
|
|
- handle SCC profiles.
|
|
|
|
|
- num-tile-cols and num-tile-row properties to specify the number
|
|
|
|
|
of tiles to use.
|
|
|
|
|
- the low-delay-b property was deprecated and is now determined
|
|
|
|
|
automatically.
|
|
|
|
|
- improved profile selection through caps.
|
|
|
|
|
|
|
|
|
|
VAAPI Decoders
|
|
|
|
|
|
|
|
|
|
- Decoder surfaces are not bound to their context any longer and can
|
|
|
|
|
thus be created and used dynamically, removing the deadlock
|
|
|
|
|
headache.
|
|
|
|
|
|
|
|
|
|
- Reverse playback is now fluid
|
|
|
|
|
|
|
|
|
|
- Forward Region-of-Interest (ROI) metas downstream
|
|
|
|
|
|
|
|
|
|
- GLTextureUploadMeta uses DMABuf when GEM is not available. Now
|
|
|
|
|
Gallium drivers can use this meta for rendering with EGL.
|
|
|
|
|
|
|
|
|
|
- vaapivp9dec: support for 4:2:2 and 4:4:4 chroma type streams
|
|
|
|
|
|
|
|
|
|
- vaapih265dec: skip all pictures prior to the first I-frame. Enable
|
|
|
|
|
passing range extension flags to the driver. Handle SCC profiles.
|
|
|
|
|
|
|
|

|
|
- omxh264enc, omxh265enc: negotiate subframe mode via caps. To enable

GStreamer Editing Services and NLE
|
2017-05-04 12:36:55 +00:00
|
|
|
|
|
2020-09-07 23:01:33 +00:00
|
|
|
|
- Added nested timelines and subproject support so that GES projects
|
|
|
|
|
can be used as clips, potentially serializing nested projects in the
|
|
|
|
|
main file or referencing external project files.
|
|
|
|
|
|
|
|
|
|
- Implemented an OpenTimelineIO GES formatter. This means GES and
|
|
|
|
|
GStreamer can now load and save projects in all the formats
|
|
|
|
|
supported by otio.
|
|
|
|
|
|
|
|
|
|
- Implemented a GESMarkerList object which allow setting timed
|
|
|
|
|
metadata on any GES object.
|
|
|
|
|
|
|
|
|
|
- Fixed audio rendering issues during clip transition by ensuring that
|
|
|
|
|
a single segment is pushed into encoders.
|
|
|
|
|
|
|
|
|
|
- The GESUriClipAsset API is now MT safe.
|
|
|
|
|
|
|
|
|
|
- Added ges_meta_container_register_static_meta() to allow fixing a
|
|
|
|
|
type for a specific metadata without actually setting a value.
|
|
|
|
|
|
|
|
|
|
- The framepositioner element now handles resizing the project and
|
|
|
|
|
keeps the same positioning when the aspect ratio is not changed .
|
|
|
|
|
|
|
|
|
|
- Reworked the documentation, making it more comprehensive and much
|
|
|
|
|
more detailed.
|
|
|
|
|
|
|
|
|
|
- Added APIs to retrieve natural size and framerate of a clip (for
|
|
|
|
|
example in the case of URIClip it is the framerate/size of the
|
|
|
|
|
underlying file).
|
|
|
|
|
|
|
|
|
|
- ges_container_edit() is now deprecated and GESTimelineElement gained
|
|
|
|
|
the ges_timeline_element_edit() method so the editing API is now
|
|
|
|
|
usable from any element in the timeline.
|
|
|
|
|
|
|
|
|
|
- GESProject::loading was added so applications can be notified about
|
|
|
|
|
when a new timeline starts loading.
|
|
|
|
|
|
|
|
|
|
- Implemented the GstStream API in GESTimeline.
|
|
|
|
|
|
|
|
|
|
- Added a way to add a timeoverlay inside the test source (potentially
|
|
|
|
|
with timecodes).
|
|
|
|
|
|
|
|
|
|
- Added APIs to convert times to frame numbers and vice versa:
|
|
|
|
|
|
|
|
|
|
- ges_timeline_get_frame_time()
|
|
|
|
|
|
|
|
|
|
- ges_timeline_get_frame_at()
|
|
|
|
|
|
|
|
|
|
- ges_clip_asset_get_frame_time()
|
|
|
|
|
|
|
|
|
|
- ges_clip_get_timeline_time_from_source_frame()
|
|
|
|
|
|
|
|
|
|
Quite a few validate tests have been implemented to check the
|
|
|
|
|
behavior for various demuxer/codec formats
|
|
|
|
|
|
|
|
|
|
- Added ges_layer_set_active_for_tracks() which allows muting layers
|
|
|
|
|
for the specified tracks
|
|
|
|
|
|
|
|
|
|
- Deprecated GESImageSource and GESMultiFileSource now that we have
|
|
|
|
|
imagesequencesrc which handles the imagesequence “protocol”
|
|
|
|
|
|
|
|
|
|
- Stopped exposing ‘deinterlacing’ children properties for clip types
|
|
|
|
|
where they do not make sense.
|
|
|
|
|
|
|
|
|
|
- Added support for simple time remapping effects

GStreamer validate

|
|
|
|
|
2020-09-07 23:01:33 +00:00
|
|
|
|
- Introduced the concept of “Test files” allowing to implement “all
|
|
|
|
|
included” test cases, meaning that inside the file the following can
|
|
|
|
|
be defined:
|
|
|
|
|
|
|
|
|
|
- The application arguments
|
|
|
|
|
- The validate configurations
|
|
|
|
|
- The validate scenario
|
|
|
|
|
|
|
|
|
|
This replaces the previous big dictionary file in
|
|
|
|
|
gst-validate-launcher to implement specific test cases.
|
|
|
|
|
|
|
|
|
|
We set several variables inside the files (as well as inside
|
|
|
|
|
scenarios and config files) to make them relocatable.
|
|
|
|
|
|
|
|
|
|
The file format has been enhanced so it is easier to read and write,
|
|
|
|
|
for example line ending with a coma or (curly) brackets can now be
|
|
|
|
|
used as continuation marker so you do not need to add \ at the end
|
|
|
|
|
of lines to write a structure on several lines.
|
|
|
|
|
|
|
|
|
|
- Support the imagesequence “protocol” and added integration tests for
|
|
|
|
|
it.
|
|
|
|
|
|
|
|
|
|
- Added action types to allow the scenario to run the Test Clock for
|
|
|
|
|
better reproducibility of tests.
|
|
|
|
|
|
|
|
|
|
- Support generating tests to check that seeking is frame accurate
|
|
|
|
|
(base on ssim).
|
|
|
|
|
|
|
|
|
|
- Added ways to record buffers checksum (in different ways) in the
|
|
|
|
|
validateflow module.
|
|
|
|
|
|
|
|
|
|
- Added vp9 encoding tests.
|
|
|
|
|
|
|
|
|
|
- Enhanced seeking action types implementation to allow support for
|
|
|
|
|
segment seeks.
|
|
|
|
|
|
|
|
|
|
- Output improvements:
|
|
|
|
|
|
|
|
|
|
- Logs are now in markdown formats (and bat is used to dump them
|
|
|
|
|
if available).
|
|
|
|
|
- File format issues in scenarios/configs/tests files are nicely
|
|
|
|
|
reported with the line numbers now.

2020-09-07 23:01:33 +00:00
|
|
|
|
- Support mapping buffers without any memcpy:
|
|
|
|
|
|
|
|
|
|
- Added a ContextManager to make the API more pythonic

GStreamer C# Bindings

2019-01-17 01:38:59 +00:00
|
|
|
|
|
2020-09-07 23:01:33 +00:00
|
|
|
|
- Bind gst_buffer_new_wrapped() manually to fix memory handling.
|
|
|
|
|
|
|
|
|
|
- Fix gst_promise_new_with_change_func() where bindgen didn’t properly
|
|
|
|
|
detect the func as a closure.
|
|
|
|
|
|
|
|
|
|
- Declare GstVideoOverlayComposition and GstVideoOverlayRectangle as
|
|
|
|
|
opaque type and subclasses of Gst.MiniObject. This changes the API
|
|
|
|
|
but without this all usage will cause memory corruption or simply
|
|
|
|
|
not work.
|
|
|
|
|
|
|
|
|
|
- on Windows, look for gstreamer, glib and gobject DLLs using the MSVC
|
|
|
|
|
naming convention (i.e. gstvideo-1.0-0.dll instead of
|
|
|
|
|
libgstvideo-1.0-0.dll).
|
|
|
|
|
|
|
|
|
|
The names of these DLLs have to be hardcoded in the bindings, and
|
|
|
|
|
most C# users will probably be using the Microsoft toolchain anyway.
|
|
|
|
|
|
|
|
|
|
This means that the MSVC compiler is now required to build the
|
|
|
|
|
bindings, MingW will no longer work out of the box.
|
|

GStreamer Rust Bindings and Rust Plugins
|
|
|
|
|
|
|
|
|
|
The GStreamer Rust bindings are released separately with a different
|
|
|
|
|
release cadence that’s tied to gtk-rs, but the latest release has
|
|
|
|
|
already been updated for the new GStreamer 1.18 API, so there’s
|
|
|
|
|
absolutely no excuse why your next GStreamer application can’t be
|
|
|
|
|
written in Rust anymore.
|
|
|
|
|
|
|
|
|
|
gst-plugins-rs, the module containing GStreamer plugins written in Rust,
|
|
|
|
|
has also seen lots of activity with many new elements and plugins.
|
|
|
|
|
|
|
|
|
|
What follows is a list of elements and plugins available in
|
|
|
|
|
gst-plugins-rs, so people don’t miss out on all those potentially useful
|
|
|
|
|
elements that have no C equivalent.
|
|
|
|
|
|
|
|
|
|
Rust audio plugins
|
|
|
|

|
encoder implementation
|
|
|
|
|
- rsflvdemux: Alternative to the flvdemux FLV demuxer element from
|
|
|
|
|
gst-plugins-good, not feature-equivalent yet

|
|
|
|
- rsgifenc/rspngenc: GIF/PNG encoder elements based on the pure-Rust

|
|
showing a fallback stream instead
|
|
|
|
|
- threadshare: Set of elements that provide alternatives for various
|
|

|
|
|
|
- The Autotools build system has finally been removed in favour of the
|
|
|
|
|
Meson build system. Developers who currently use gst-uninstalled
|
|
|
|
|
should move to gst-build.

|
|
|
|
|
2020-06-19 18:13:36 +00:00
|
|
|
|
- API and plugin documentation are no longer built with gtk_doc. The
|
|
|
|
|
gtk_doc documentation has been removed in favour of a new unified
|
2020-09-07 23:01:33 +00:00
|
|
|
|
documentation module built with hotdoc (also see “Documentation
|
|
|
|
|
improvements” section below). Distributors should use the
|
|
|
|
|
documentation release tarball instead of trying to package hotdoc
|
|
|
|
|
and building the documentation from scratch.
|
|
|
|
|
|
|
|
|
|
- gst-plugins-bad now includes an internal copy of libusrsctp, as
|
|
|
|
|
there are problems in usrsctp with global shared state, lack of API
|
|
|
|
|
stability guarantees, and the absence of any kind of release
|
|
|
|
|
process. We also can’t rely on distros shipping a version with the
|
|
|
|
|
fixes we need. Both firefox and Chrome bundle their own copies too.
|
|
|
|
|
It is still possible to build against an external copy of usrsctp if
|
|
|
|
|
so desired.
|
|
|
|
|
|
|
|
|
|
- nvcodec no longer needs the NVIDIA NVDEC/NVENC SDKs available at
|
|
|
|
|
build time, only at runtime. This allows distributions to ship this
|
|
|
|
|
plugin by default and it will just start to work when the required
|
|
|
|
|
run-time SDK libraries are installed by the user, without users
|
|
|
|
|
needing to build and install the plugin from source.
|
|
|
|
|
|
|
|
|
|
- the gst-editing-services tarball is now named gst-editing-services
|
|
|
|
|
for consistency (used to be gstreamer-editing-services).
|
|
|
|
|
|
|
|
|
|
- the gst-validate tarball has been superseded by the gst-devtools
|
|
|
|
|
tarball for consistency with the git module name.
|
|
|
|
|
|
|
|
|
|
gst-build
|
|
|
|
|
|
|
|
|
|
gst-build is a meta-module and serves primarily as our uninstalled
|
|
|
|
|
development environment. It makes it easy to build most of GStreamer,
|
|
|
|
|
but unlike Cerbero it only comes with a limited number of external
|
|
|
|
|
dependencies that can be built as subprojects if they are not found on
|
|
|
|
|
the system.
|
|
|
|
|
|
|
|

|
gst-build is based on Meson and replaces the old autotools
|
|
|
|
|
gst-uninstalled script.
|
|
|
|
|
|
|
|
|
|
- The ‘uninstalled’ target has been renamed to ‘devenv’
|
|
|
|
|
|
|
|
|
|
- Experimental gstreamer-full library containing all built plugins and
|
|
|
|
|
their deps when building with -Ddefault_library=static. A monolithic
|
|
|
|
|
library is easier to distribute, and may be required in some
|
|
|
|
|
environments. GStreamer core, GLib and GObject are always included,
|
|
|
|
|
but external dependencies are still dynamically linked. The
|
|
|
|
|
gst-full-libraries meson option allows adding other GStreamer
|
|
|
|
|
libraries to the gstreamer-full build. This is an experiment for now
|
|
|
|
|
and its behaviour or API may still change in future releases.
|
|
|
|
|
|
|
|
|
|
- Add glib-networking as a subproject when glib is a subproject and
|
|
|
|
|
load gio modules in the devenv, tls option control whether to use
|
|
|
|
|
openssl or gnutls.
|
|
|
|
|
|
|
|
|
|
- git-worktree: Allow multiple worktrees for subproject branches
|
|
|
|
|
|
|
|
|
|
- Guard against meson being run from inside the uninstalled devenv, as
|
|
|
|
|
this might have unexpected consequences.
|
|
|
|
|
|
|
|
|
|
- our ffmpeg and x264 meson ports have been updated to the latest
|
|
|
|
|
stable version (you might need to update the subprojects checkout
|
|
|
|
|
manually though, or just remove the checkouts so meson checks out
|
|
|
|
|
the latest version again; improvements for this are pending in
|
|
|
|
|
meson, but not merged yet).

Cerbero
|
|
|
|
|
|
|
|
|
|
Cerbero is a meta build system used to build GStreamer plus dependencies
|
|
|
|
|
on platforms where dependencies are not readily available, such as
|
|
|
|
|
Windows, Android, iOS and macOS.

General improvements
|
|
|
|
|
|
|
|
|
|
- Recipe build steps are done in parallel wherever possible. This
|
|
|
|
|
leads to massive improvements in overall build time.
|
|
|
|
|
- Several recipes were ported to Meson, which improved build times
|
|
|
|
|
- Moved from using both GnuTLS and OpenSSL to only OpenSSL
|
|
|
|
|
- Moved from yasm to nasm for all assembly compilation
|
|
|
|
|
- Support zsh when running the cerbero shell command
|
|
|
|
|
- Numerous version upgrades for dependencies
|
|
|
|
|
- Default to xz for tarball binary packages. bz2 can be selected with
|
|
|
|
|
the --compress-method option to package.
|
|
|
|
|
- Added boolean variant for controlling the optimization level:
|
|
|
|
|
-v optimization
|
|
|
|
|
- Ship .pc pkgconfig files for all plugins in the binary packages
|
|
|
|
|
- CMake and nasm will only be built by Cerbero if the system versions
|
|
|
|
|
are unusable
|
|
|
|
|
- The nvcodec variant was removed and the nvcodec plugin is built by
|
|
|
|
|
default now (as it no longer requires the SDK to be installed at
|
|
|
|
|
build time, only at runtime)
|
|
|
|
|
|
|
|
|
|
macOS / iOS
|
|
|
|
|
|
|
|
|
|
- Minimum iOS SDK version bumped to 11.0
|
|
|
|
|
- Minimum macOS SDK version bumped to 10.11
|
|
|
|
|
- No longer need to manually add support for newer iOS SDK versions
|
|
|
|
|
- Added Vulkan elements via MoltenVK
|
|
|
|
|
- Build times were improved by code-signing all build tools
|
|
|
|
|
- macOS framework ships all gstreamer libraries instead of an outdated
|
|
|
|
|
subset
|
|
|
|
|
- Ship pkg-config in the macOS framework package
|
|
|
|
|
- fontconfig: Fix EXC_BAD_ACCESS crash on iOS ARM64
|
|
|
|
|
- Improved App Store compatibility by setting LC_VERSION_MIN_MACOSX,
|
|
|
|
|
fixing relocations, and improved bitcode support
|
|
|
|
|
|
|
|
|
|
Windows
|
|
|
|
|
|
|
|
|
|
- MinGW-GCC toolchain was updated to 8.2. It uses the Universal CRT
|
|
|
|
|
instead of MSVCRT which eliminates cross-CRT issues in the Visual
|
|
|
|
|
Studio build.
|
|
|
|
|
- Require Windows 7 or newer for running binaries produced by Cerbero
|
|
|
|
|
- Require Windows x86_64 for running Cerbero to build binary packages
|
|
|
|
|
- Cerbero no longer uses C:/gstreamer/1.0 as a prefix when building.
|
|
|
|
|
That prefix is reserved for use by the MSI installers.
|
|
|
|
|
- Several recipes can now be buit with Visual Studio instead of MinGW.
|
|
|
|
|
Ported to meson: opus, libsrtp, harfbuzz, cairo, openh264, libsoup,
|
|
|
|
|
libusrsctp. Existing build system: libvpx, openssl.
|
|
|
|
|
- Support building using Visual Studio for 32-bit x86. Previously we
|
|
|
|
|
only supported building for 32-bit x86 using the MinGW toolchain.
|
|
|
|
|
- Fixed annoying msgmerge popups in the middle of cerbero builds
|
|
|
|
|
- Added configuration options vs_install_path and vs_install_version
|
|
|
|
|
for specifying custom search locations for older Visual Studio
|
|
|
|
|
versions that do not support vswhere. You can set these in
|
|
|
|
|
~/.cerbero/cerbero.cbc where ~ is the MSYS homedir, not your Windows
|
|
|
|
|
homedir.
|
|
|
|
|
- New Windows-specific plugins: d3d11, mediafoundation, wasapi2
|
|
|
|
|
- Numerous compatibility and reliability fixes when running Cerbero on
|
|
|
|
|
Windows, especially non-English locales
|
|
|
|
|
- proxy-libintl now exports the same symbols as gettext, which makes
|
|
|
|
|
it a drop-in replacement
|
|
|
|
|
- New mapping variant for selecting the Visual Studio CRT to use:
|
|
|
|
|
-v vscrt=<value>. Valid values are md, mdd, and auto (default). A
|
|
|
|
|
separate prefix is used when building with either md (release) or
|
|
|
|
|
mdd (debug), and the outputted package will have +debug in the
|
|
|
|
|
filename. This variant is also used for selecting the correct Qt
|
|
|
|
|
libraries (debug vs release) to use when building with -v qt5 on
|
|
|
|
|
Windows.
|
|
|
|
|
- Support cross-compile on Windows to Windows ARM64 and ARMv7
|
|
|
|
|
- Support cross-compile on Windows to the Universal Windows Platform
|
|
|
|
|
(UWP). Only the subset of plugins that can be built entirely with
|
|
|
|
|
Visual Studio will be selected in this case. To do so, use the
|
|
|
|
|
config/cross-uwp-universal.cbc configuration, which will build
|
|
|
|
|
ARM64, x86, and x86_64 binaries linked to the release CRT, with
|
|
|
|
|
optimizations enabled, and debugging turned on. You can combine this
|
|
|
|
|
with -v vscrt=mdd to produce binaries linked to the debug CRT. You
|
|
|
|
|
can turn off optimizations with the -v nooptimization variant.
|
|
|
|
|
|
|
|
|
|
Windows MSI installer
|
|
|
|
|
|
|
|
|
|
- Require Windows 7 or newer for running GStreamer
|
|
|
|
|
- Fixed some issues with shipping of pkg-config in the Windows
|
|
|
|
|
installers
|
|
|
|
|
- Plugin PDB debug files are now shipped in the development package,
|
|
|
|
|
not the runtime package
|
|
|
|
|
- Ship installers for 32-bit binaries built with Visual Studio
|
|
|
|
|
- Ship debug and release “universal” (ARM64, X86, and X86_64) tarballs
|
|
|
|
|
built for the Universal Windows Platform
|
|
|
|
|
- Windows MSI installers now install into separate prefixes when
|
|
|
|
|
building with MSVC and MinGW. Previously both would be installed
|
|
|
|
|
into C:/gstreamer/1.0/x86 or C:/gstreamer/1.0/x86_64. Now, the
|
|
|
|
|
installation prefixes are:

|
|
|
|
|
|
|
|

shell and runit cerbero commands
|
|
|
|
|
- Added bash-completion support inside the cerbero shell on Linux
|

|
|
|
- d3d11videosink: new Direct3D11-based video sink with support for
|
|
|
|
|
HDR10 rendering if supported.
|
|
|
|
|
|
|
|
|
|
- Hardware-accelerated video decoding on Windows via DXVA2 /
|
|
|
|
|
Direct3D11 using native Windows APIs rather than per-vendor SDKs
|
|
|
|
|
(like MSDK for Intel or NVCODEC for NVidia). Plus modern Direct3D11
|
|
|
|
|
integration rather than the almost 20-year old Direct3D9 from
|
|
|
|
|
Windows XP times used in d3dvideosink. Formats supported for
|
|
|
|
|
decoding are H.264, H.265, VP8, and VP9, and zero-copy operation
|
|
|
|
|
should be supported in combination with the new d3d11videosink. See
|
|
|
|
|
Seungha’s blog post “Windows DXVA2 (via Direct3D 11) Support in
|
|
|
|
|
GStreamer 1.17” for more details.
|
|
|
|
|
|
|
|
|
|
- Microsoft Media Foundation plugin for hardware-accelerated video
|
|
|
|
|
encoding on Windows using native Windows APIs rather than per-vendor
|
|
|
|
|
SDKs. Formats supported for encoding are H.264, H.265 and VP9. Also
|
|
|
|
|
includes audio encoders for AAC and MP3. See Seungha’s blog post
|
|
|
|
|
“Bringing Microsoft Media Foundation to GStreamer” for some more
|
|
|
|
|
details about this.
|
|
|
|
|
|
|
|
|
|
- new mfvideosrc video capture source element using the latest Windows
|
|
|
|
|
APIs rather than ancient APIs used by ksvideosrc/winks. ksvideosrc
|
|
|
|
|
should be considered deprecated going forward.
|
|
|
|
|
|
|
|
|
|
- d3d11: add d3d11convert, a color space conversion and rescaling
|
|
|
|
|
element using shaders, and introduce d3d11upload and d3d11download
|
|
|
|
|
elements that work just like glupload and gldownload but for D3D11.
|
|
|
|
|
|
|
|
|
|
- Universal Windows Platform (UWP) support, including official
|
|
|
|
|
GStreamer binary packages for it. Check out Nirbheek’s latest blog
|
|
|
|
|
post “GStreamer 1.18 supports the Universal Windows Platform” for
|
|
|
|
|
more details.
|
|
|
|
|
|
|
|
|
|
- systemclock correctness and reliability fixes, and also don’t start
|
|
|
|
|
the system clock at 0 any longer (which shouldn’t make any
|
|
|
|
|
difference to anyone, as absolute clock time values are supposed to
|
|
|
|
|
be meaningless in themselves, only the rate of increase matters).
|
|
|
|
|
|
|
|
|
|
- toolchain specific plugin registry: the registry cache is now named
|
|
|
|
|
differently for MSVC and MinGW toolchains/packages, which should
|
|
|
|
|
avoid problems when switching between binaries built with a
|
|
|
|
|
different toolchain.
|
|
|
|
|
|
|
|
|
|
- new wasapi2 plugin mainly to support UWP applications. The core
|
|
|
|
|
logic of this plugin is almost identical to existing wasapi plugin,
|
|
|
|
|
but the main target is Windows 10 and UWP. This plugin uses WinRT
|
|
|
|
|
APIs, so will likely not work on Windows 8 or older. Unlike the
|
|
|
|
|
existing wasapi plugin, this plugin supports automatic stream
|
|
|
|
|
routing (auto fallback when device was removed) and device level
|
|
|
|
|
mute/volume control. Exclusive streaming mode is not supported,
|
|
|
|
|
however, and loopback features are not implemented yet. It is also
|
|
|
|
|
only possible to build this plugin with MSVC and the Windows 10 SDK,
|
|
|
|
|
it can’t be cross-compiled with the MingW toolchain.
|
|
|
|
|
|
|
|
|
|
- new dxgiscreencapsrc element which uses the Desktop Duplication API
|
|
|
|
|
to capture the desktop screen at high speed. This is only supported
|
|
|
|
|
on Windows 8 or later. Compared to the existing elements
|
|
|
|
|
dxgiscreencapsrc offers much better performance, works in High DPI
|
|
|
|
|
environments and draws an accurate mouse cursor.
|
|
|
|
|
|
|
|
|
|
- d3dvideosink was downgraded to secondary rank, d3d11videosink is
|
|
|
|
|
preferred now. Support OverlayComposition for GPU overlay
|
|
|
|
|
compositing of subtitles and logos.
|
|
|
|
|
|
|
|
|
|
- debug log output fixes, esp. with a non-UTF8 locale/codepage
|
|
|
|
|
|
|
|
|
|
- speex, jack: fixed crashes on Windows caused by cross-CRT issues
|
|
|
|
|
|
|
|
|
|
- gst-play-1.0 interactive keyboard controls now also work on Windows
|
|
|
|
|
|
|
|
|
|
Linux
|
|
|
|
|
|
|
|
|
|
- kmssink: Add support for P010 and P016 formats
|
|
|
|
|
|
|
|
|
|
- vah264dec: new experimental va plugin with an element for H.264
|
|
|
|
|
decoding with VA-API. This novel approach, different from
|
|
|
|
|
gstreamer-vaapi, uses the gstcodecs library for decoder state
|
|
|
|
|
handling, which it is hoped will make for cleaner code because it
|
|
|
|
|
uses VA-API without further layers or wrappers. Check out Víctor’s
|
|
|
|
|
blog post “New VA-API H.264 decoder in gst-plugins-bad” for the full
|
|
|
|
|
lowdown and the limitations of this new plugin, and how to give it a
|
|
|
|
|
spin.
|
|
|
|
|
|
|
|
|
|
- v4l2codecs: introduce a V4L2 CODECs Accelerator. This plugin will
|
|
|
|
|
support the new CODECs uAPI in the Linux kernel, which consists of
|
|
|
|
|
an accelerator interface similar to DXVA, NVDEC, VDPAU and VAAPI. So
|
|
|
|
|
far H.264 and VP8 are supported. This is used on certain embedded
|
|
|
|
|
systems such as i.mx8m, rk3288, rk3399, Allwinner H-series SoCs.
|
|
|
|
|

Documentation improvements
|
|
|
|
|
|
|
|
|
|
- unified documentation containing tutorials, API docs, plugin docs,
|
|
|
|
|
etc. all under one roof, shipped in form of a documentation release
|
|
|
|
|
tarball containing both devhelp and html documentation.
|
|
|
|
|
|
|
|
|
|
- all documentation is now generated using hotdoc, gtk-doc is no
|
|
|
|
|
longer used. Distributors should use the above-mentioned
|
|
|
|
|
documentation release tarball instead of trying to package hotdoc
|
|
|
|
|
and building the documentation from scratch.
|
|
|
|
|
|
|
|
|
|
- there is now documentation for wrapper plugins like gst-libav and
|
|
|
|
|
frei0r, as well as tracer plugins.
|
|
|
|
|
|
|
|
|
|
- for more info, check out Thibault’s “GStreamer Documentation”
|
|
|
|
|
lightning talk from the 2019 GStreamer Conference.
|
|
|
|
|
|
|
|
|
|
- new API for plugins to support the documentation system:
|
|
|
|
|
|
|
|
|
|
- new GParamSpecFlag GST_PARAM_DOC_SHOW_DEFAULT to make
|
|
|
|
|
gst-inspect-1.0 (and the documentation) show the paramspec’s
|
|
|
|
|
default value rather than the actually set value as default
|
|
|
|
|
- GstPadTemplate getter and setter for “documentation caps”,
|
|
|
|
|
gst_pad_template_set_documentation_caps() and
|
|
|
|
|
gst_pad_template_get_documentation_caps(): This can be used in
|
|
|
|
|
elements where the caps of pad templates are dynamically
|
|
|
|
|
generated and/or dependent on the environment, to override the
|
|
|
|
|
caps shown in the documentation (usually to advertise the full
|
|
|
|
|
set of possible caps).
|
|
|
|
|
- gst_type_mark_as_plugin_api() for marking types as plugin API,
|
|
|
|
|
used for plugin-internal types like enums, flags, pad
|
|
|
|
|
subclasses, boxed types, and such.
|
|
|
|
|
|
|
|
|
|
Possibly Breaking Changes
|
|
|
|
|
|
|
|
|
|
- GstVideo: the canonical list of raw video formats (for use in caps)
|
|
|
|
|
has been reordered, so video elements such as videotestsrc or
|
|
|
|
|
videoconvert might negotiate to a different format now than before.
|
|
|
|
|
The new format might be a higher-quality format or require more
|
|
|
|
|
processing overhead, which might affect pipeline performance.
|
|
|
|
|
|
|
|
|
|
- mpegtsdemux used to wrongly advertise H.264 and H.265 video
|
|
|
|
|
elementary streams as alignment=nal. This has now been fixed and
|
|
|
|
|
changed to alignment=none, which means an h264parse or h265parse
|
|
|
|
|
element is now required after tsdemux for some pipelines where there
|
|
|
|
|
wasn’t one before, e.g. in transmuxing scenarios (tsdemux ! tsmux).
|
|
|
|
|
Pipelines without such a parser may now fail to link or error out at
|
|
|
|
|
runtime. As parsers after demuxers and before muxers have been
|
|
|
|
|
generally required for a long time now it is hoped that this will
|
|
|
|
|
only affect a small number of applications or pipelines.
|
|
|
|
|
|
|
|
|
|
- The Android opensles audio source and sink used to have hard-coded
|
|
|
|
|
buffer-/latency-time values of 20ms. This is no longer needed with
|
|
|
|
|
newer Android versions and has now been removed. This means a higher
|
|
|
|
|
or lower value might now be negotiated by default, which can affect
|
|
|
|
|
pipeline performance and latency.

- GStreamer 1.18 versions <= 1.18.4 would fail to build on Linux with
|
|
|
|
|
Meson 0.58 due to an issue with the include directories. Either
|
|
|
|
|
apply the patch or build with an older Meson version (<= 0.57) until
|
|
|
|
|
there is a GStreamer 1.18.5 release that includes the fix.

|
After the 1.18.0 release there will be several 1.18.x bug-fix releases
|
2018-03-03 21:51:49 +00:00
|
|
|
|
which will contain bug fixes which have been deemed suitable for a
|
|
|
|
|
stable branch, but no new features or intrusive changes will be added to
|
2020-06-19 18:13:36 +00:00
|
|
|
|
a bug-fix release usually. The 1.18.x bug-fix releases will be made from
|
|
|
|
|
the git 1.18 branch, which will be a stable branch.

Schedule for 1.20

2020-06-19 18:13:36 +00:00
|
|
|
|
Our next major feature release will be 1.20, and 1.19 will be the
|
|
|
|
|
unstable development version leading up to the stable 1.20 release. The
|
|
|
|
|
development of 1.19/1.20 will happen in the git master branch.
|
2017-05-04 12:36:55 +00:00
|
|
|
|
|
2020-09-07 23:01:33 +00:00
|
|
|
|
The plan for the 1.20 development cycle is yet to be confirmed, but it
|
2021-09-08 19:01:46 +00:00
|
|
|
|
is now expected that feature freeze will take place some time in
|
|
|
|
|
September/October 2021, with the first 1.20 stable release hopefully
|
|
|
|
|
towards the end of October 2021.
|
2017-05-04 12:36:55 +00:00
|
|
|
|
|
2020-06-19 18:13:36 +00:00
|
|
|
|
1.20 will be backwards-compatible to the stable 1.18, 1.16, 1.14, 1.12,
|
|
|
|
|
1.10, 1.8, 1.6, 1.4, 1.2 and 1.0 release series.
