## Introduction
@ -26,684 +24,127 @@ improvements.
## Highlights
- new `msdk` plugin for Intel's Media SDK for hardware-accelerated video
encoding and decoding on Intel graphics hardware on Windows or Linux.
- `x264enc` can now use multiple x264 library versions compiled for different
bit depths at runtime, to transparently provide support for multiple bit
depths.
- `videoscale` and `videoconvert` now support multi-threaded scaling and
conversion, which is particularly useful with higher resolution video.
- `h264parse` will now automatically insert AU delimiters if needed when
outputting byte-stream format, which improves standard compliance and
is needed in particular for HLS playback on iOS/macOS.
- `rtpbin` has acquired bundle support for incoming streams
- this section will be completed shortly
## Major new features and changes
### Noteworthy new API
- The video library gained support for a number of new video formats:
- `GBR_12LE`, `GBR_12BE`, `GBRA_12LE`, `GBRA_12BE` (planar 4:4:4 RGB/RGBA, 12 bits per channel)
- `GBRA_10LE`, `GBRA_10BE` (planar 4:4:4:4 RGBA, 10 bits per channel)
- `GBRA` (planar 4:4:4:4 ARGB, 8 bits per channel)
- `I420_12BE`, `I420_12LE` (planar 4:2:0 YUV, 12 bits per channel)
- `I422_12BE`,`I422_12LE` (planar 4:2:2 YUV, 12 bits per channel)
- `Y444_12BE`, `Y444_12LE` (planar 4:4:4 YUV, 12 bits per channel)
- `VYUY` (another packed 4:2:2 YUV format)
- The high-level `GstPlayer` API was extended with functions for taking video
snapshots and enabling accurate seeking. It can optionally also use the
still-experimental `playbin3` element now.
- this section will be filled in shortly
### New Elements
- msdk: new plugin for Intel's Media SDK for hardware-accelerated video encoding
and decoding on Intel graphics hardware on Windows or Linux. This includes
an H.264 encoder/decoder (`msdkh264dec`, `msdkh264enc`),
an H.265 encoder/decoder (`msdkh265dec`, `msdkh265enc`),
an MJPEG encoder/encoder (`msdkmjpegdec`, `msdkmjpegenc`),
an MPEG-2 video encoder (`msdkmpeg2enc`) and a VP8 encoder (`msdkvp8enc`).
- `iqa` is a new Image Quality Assessment plugin based on [DSSIM][dssim],
similar to the old (unported) videomeasure element.
- The `faceoverlay` element, which allows you to overlay SVG graphics over
a detected face in a video stream, has been ported from 0.10.
- our `ffmpeg` wrapper plugin now exposes/maps the ffmpeg Opus audio decoder
(`avdec_opus`) as well as the GoPro CineForm HD / CFHD decoder (`avdec_cfhd`),
and also a parser/writer for the IVF format (`avdemux_ivf` and `avmux_ivf`).
- `audiobuffersplit` is a new element that splits raw audio buffers into
equal-sized buffers
- `audiomixmatrix` is a new element that mixes N:M audio channels according to
a configured mix matrix.
- The `timecodewait` element got renamed to `avwait` and can operate in
different modes now.
- The `opencv` video processing plugin has gained a new `dewarp` element that
dewarps fisheye images.
- `ttml` is a new plugin for parsing and rendering subtitles in Timed Text
Markup Language (TTML) format. For the time being these elements will not
be autoplugged during media playback however, unless the `GST_TTML_AUTOPLUG=1`
environment variable is set. Only the EBU-TT-D profile is supported at this
point.

- this section will be filled in shortly
### New element features and additions
- `x264enc` can now use multiple x264 library versions compiled for different
bit depths at runtime, to transparently provide support for multiple bit
depths. A new configure parameter `--with-x264-libraries` has been added to
specify additional paths to look for additional x264 libraries to load.
Background is that the libx264 library is always compile for one specific
bit depth and the `x264enc` element would simply support the depth supported
by the underlying library. Now we can support multiple depths.
- this section will be filled in shortly
- `x264enc` also picks up the interlacing mode automatically from the input
caps now and passed interlacing/TFF information correctly to the library.
- `videoscale` and `videoconvert` now support multi-threaded scaling and
conversion, which is particularly useful with higher resolution video.
This has to be enabled explicitly via the `"n-threads"` property.
- `videorate`'s new `"rate"` property lets you set a speed factor
on the output stream
- `splitmuxsink`'s buffer collection and scheduling was rewritten to make
processing and splitting deterministic; before it was possible for a buffer
to end up in a different file chunk in different runs. `splitmuxsink` also
gained a new `"format-location-full"` signal that works just like the existing
`"format-location"` signal only that it is also passed the primary stream's
first buffer as argument, so that it is possible to construct the file name
based on metadata such as the buffer timestamp or any GstMeta attached to
the buffer. The new `"max-size-timecode"` property allows for timecode-based
splitting. `splitmuxsink` will now also automatically start a new file if the
input caps change in an incompatible way.
- `fakesink` has a new `"drop-out-of-segment"` property to not drop
out-of-segment buffers, which is useful for debugging purposes.
- `identity` gained a `"ts-offset"` property.
- both `fakesink` and `identity` now also print what kind of metas are attached
to buffers when printing buffer details via the `"last-message"` property
used by `gst-launch-1.0 -v`.
- multiqueue: made `"min-interleave-time"` a configurable property.
- video nerds will be thrilled to know that `videotestsrc`'s snow is now
deterministic. `videotestsrc` also gained some new properties to make the
ball pattern based on system time, and invert colours each second
(`"animation-mode"`, `"motion"`, and `"flip"` properties).
- `oggdemux` reverse playback should work again now. You're welcome.
- `playbin3` and `urisourcebin` now have buffering enabled by default, and
buffering message aggregation was fixed.
- `tcpclientsrc` now has a `"timeout"` property
- `appsink` has gained support for buffer lists. For backwards compatibility
reasons users need to enable this explicitly with `gst_app_sink_set_buffer_list_support()`,
however. Once activated, a pulled `GstSample` can contain either a buffer
list or a single buffer.
- `splitmuxsrc` reverse playback was fixed and handling of sparse streams, such
as subtitle tracks or metadata tracks, was improved.
- `matroskamux` has acquired support for muxing G722 audio; it also marks all
buffers as keyframes now when streaming only audio, so that `tcpserversink`
will behave properly with audio-only streams.
- `qtmux` gained support for ProRes 4444 XQ, HEVC/H.265 and CineForm (GoPro) formats,
and generally writes more video stream-related metadata into the track headers.
It is also allows configuration of the maximum interleave size in bytes and
time now. For fragmented mp4 we always write the `tfdt` atom now as required
by the DASH spec.
- `qtdemux` supports FLAC, xvid, mp2, S16L and CineForm (GoPro) tracks now, and
generally tries harder to extract more video-related information from track
headers, such as colorimetry or interlacing details. It also received a
couple of fixes for the scenario where upstream operates in TIME format and
feeds chunks to qtdemux (e.g. DASH or MSE).
- `audioecho` has two new properties to apply a delay only to certain channels
to create a surround effect, rather than an echo on all channels. This is
useful when upmixing from stereo, for example. The `"surround-delay"` property
enables this, and the `"surround-mask"` property controls which channels
are considered surround sound channels in this case.
- `webrtcdsp` gained various new properties for gain control and also exposes
voice activity detection now, in which case it will post `"voice-activity"`
messages on the bus whenever the voice detection status changes.
- The `decklink` capture elements for Blackmagic Decklink cards have seen a
number of improvements:
- `decklinkvideosrc` will post a warning message on "no signal" and an info
message when the signal lock has been (re)acquired. There is also a new
read-only `"signal"` property that can be used to query the signal lock
status. The `GAP` flag will be set on buffers that are captured without
a signal lock. The new `drop-no-signal-frames` will make `decklinkvideosrc`
drop all buffers that have been captured without an input signal. The
`"skip-first-time"` property will make the source drop the first few
buffers, which is handy since some devices will at first output buffers
with the wrong resolution before they manage to figure out the right input
format and decide on the actual output caps.
- `decklinkaudiosrc` supports more than just 2 audio channels now.
- The capture sources no longer use the "hardware" timestamps which turn
out to be useless and instead just use the pipeline clock directly.
- `srtpdec` now also has a readonly `"stats"` property, just like `srtpenc`.
- `rtpbin` gained RTP bundle support, as used by e.g. WebRTC. The first
rtpsession will have a `rtpssrcdemux` element inside splitting the streams
based on their SSRC and potentially dispatch to a different rtpsession.
Because retransmission SSRCs need to be merged with the corresponding media
stream the `::on-bundled-ssrc` signal is emitted on `rtpbin` so that the
application can find out to which session the SSRC belongs.
- `rtprtxqueue` gained two new properties exposing retransmission
statistics (`"requests"` and `"fulfilled-requests"`)
- `kmssink` will now use the preferred mode for the monitor and render to the
base plane if nothing else has set a mode yet. This can also be done forcibly
in any case via the new `"force-modesetting"` property. Furthermore, `kmssink`
now allows only the supported connector resolutions as input caps in order to
avoid scaling or positioning of the input stream, as `kmssink` can't know
whether scaling or positioning would be more appropriate for the use case at
hand.
- `waylandsink` can now take DMAbuf buffers as input in the presence
of a compatible Wayland compositor. This enables zero-copy transfer
from a decoder or source that outputs DMAbuf.
- `udpsrc` can be bound to more than one interface when joining a
multicast group, this is done by giving a comma separate list of
interfaces such as multicast-iface="eth0,eth1".
### Plugin moves
- `dataurisrc` moved from gst-plugins-bad to core
- The `rawparse` plugin containing the `rawaudioparse` and `rawvideoparse`
elements moved from gst-plugins-bad to gst-plugins-base. These elements
supersede the old `videoparse` and `audioparse` elements. They work the
same, with just some minor API changes. The old legacy elements still
exist in gst-plugins-bad, but may be removed at some point in the future.
- `timecodestamper` is an element that attaches time codes to video buffers
in form of `GstVideoTimeCodeMeta`s. It had a `"clock-source"` property
which has now been removed because it was fairly useless in practice. It
gained some new properties however: the `"first-timecode"` property can
be used to set the inital timecode; alternatively `"first-timecode-to-now"`
can be set, and then the current system time at the time the first buffer
arrives is used as base time for the time codes.
### Plugin and library moves
- this section will be filled in shortly
### Plugin removals
- The `mad` mp1/mp2/mp3 decoder plugin was removed from gst-plugins-ugly,
as libmad is GPL licensed, has been unmaintained for a very long time, and
there are better alternatives available. Use the `mpg123audiodec` element
from the `mpg123` plugin in gst-plugins-ugly instead, or `avdec_mp3` from
the `gst-libav` module which wraps the ffmpeg library. We expect that we
will be able to move mp3 decoding to gst-plugins-good in the next cycle
seeing that most patents around mp3 have expired recently or are about to
expire.
- this section will be filled in shortly
- The `mimic` plugin was removed from gst-plugins-bad. It contained a decoder
and encoder for a video codec used by MSN messenger many many years ago (in
a galaxy far far away). The underlying library is unmaintained and no one
really needs to use this codec any more. Recorded videos can still be played
back with the MIMIC decoder in gst-libav.
## Miscellaneous API additions
- Request pad name templates passed to `gst_element_request_pad()` may now
contain multiple specifiers, such as e.g. `src_%u_%u`.
- [`gst_buffer_iterate_meta_filtered()`][buffer-iterate-meta-filtered] is a
variant of `gst_buffer_iterate_meta()` that only returns metas of the
requested type and skips all other metas.
- [`gst_pad_task_get_state()`][pad-task-get-state] gets the current state of
a task in a thread-safe way.
- [`gst_uri_get_media_fragment_table()`][uri-get-fragment-table] provides the
media fragments of an URI as a table of key=value pairs.
- [`gst_print()`][print], [`gst_println()`][println], [`gst_printerr()`][printerr],
and [`gst_printerrln()`][printerrln] can be used to print to stdout or stderr.
These functions are similar to `g_print()` and `g_printerr()` but they also
support all the additional format specifiers provided by the GStreamer
logging system, such as e.g. `GST_PTR_FORMAT`.
- a `GstParamSpecArray` has been added, for elements who want to have array
type properties, such as the `audiomixmatrix` element for example. There are
also two new functions to set and get properties of this type from bindings:
- gst_util_set_object_array()
- gst_util_get_object_array()
- various helper functions have been added to make it easier to set or get
GstStructure fields containing caps-style array or list fields from language
bindings (which usually support GValueArray but don't know about the GStreamer
specific fundamental types):
- [`gst_structure_get_array()`][get-array]
- [`gst_structure_set_array()`][set-array]
- [`gst_structure_get_list()`][get-list]
- [`gst_structure_set_list()`][set-list]
- a new ['dynamic type' registry factory type][dynamic-type] was added to
register dynamically loadable GType types. This is useful for automatically
loading enum/flags types that are used in caps, such as for example the
`GstVideoMultiviewFlagsSet` type used in multiview video caps.
- there is a new [`GstProxyControlBinding`][proxy-control-binding] for use
with GstController. This allows proxying the control interface from one
property on one GstObject to another property (of the same type) in another
GstObject. So e.g. in parent-child relationship, one may need to call
`gst_object_sync_values()` on the child and have a binding (set elsewhere)
on the parent update the value. This is used in `glvideomixer` and `glsinkbin`
for example, where `sync_values()` on the child pad or element will call
`sync_values()` on the exposed bin pad or element.
Note that this doesn't solve GObject property forwarding, that must
be taken care of by the implementation manually or using GBinding.
- `gst_base_parse_drain()` has been made public for subclasses to use.
- `gst_base_sink_set_drop_out_of_segment()' can be used by subclasses to
prevent GstBaseSink from dropping buffers that fall outside of the segment.
- [`gst_calculate_linear_regression()`][calc-lin-regression] is a new utility
function to calculate a linear regression.
- [`gst_debug_get_stack_trace`][get-stack-trace] is an easy way to retrieve a
stack trace, which can be useful in tracer plugins.
- allocators: the dmabuf allocator is now sub-classable, and there is a new
`GST_CAPS_FEATURE_MEMORY_DMABUF` define.
- video decoder subclasses can use the newly-added function
`gst_video_decoder_allocate_output_frame_with_params()` to
pass a `GstBufferPoolAcquireParams` to the buffer pool for
each buffer allocation.
- the video time code API has gained a dedicated [`GstVideoTimeCodeInterval`][timecode-interval]
type plus related API, including functions to add intervals to timecodes.
- There is a new `libgstbadallocators-1.0` library in gst-plugins-bad, which
may go away again in future releases once the `GstPhysMemoryAllocator`
interface API has been validated by more users and was moved to
`libgstallocators-1.0` from gst-plugins-base.

### GstPlayer
New API has been added to:
- get the number of audio/video/subtitle streams:
- `gst_player_media_info_get_number_of_streams()`
- `gst_player_media_info_get_number_of_video_streams()`
- `gst_player_media_info_get_number_of_audio_streams()`
- `gst_player_media_info_get_number_of_subtitle_streams()`
- enable accurate seeking: `gst_player_config_set_seek_accurate()`
and `gst_player_config_get_seek_accurate()`
- get a snapshot image of the video in RGBx, BGRx, JPEG, PNG or
native format: [`gst_player_get_video_snapshot()`][snapshot]
- selecting use of a specific video sink element
([`gst_player_video_overlay_video_renderer_new_with_sink()`][renderer-with-vsink])
- If the environment variable `GST_PLAYER_USE_PLAYBIN3` is set, GstPlayer will
use the still-experimental `playbin3` element and the `GstStreams` API for
playback.

- this section will be filled in shortly
## Miscellaneous changes
- video caps for interlaced video may contain an optional `"field-order"` field
now in the case of `interlaced-mode=interleaved` to signal that the field
order is always the same throughout the stream. This is useful to signal to
muxers such as mp4mux. The new field is parsed from/to `GstVideoInfo` of course.
- video decoder and video encoder base classes try harder to proxy
interlacing, colorimetry and chroma-site related fields in caps properly.
- The buffer stored in the `PROTECTION` events is now left unchanged. This is a
change of behaviour since 1.8, especially for the mssdemux element which used to
decode the base64 parsed data wrapped in the protection events emitted by the
demuxer.
- `PROTECTION` events can now be injected into the pipeline from the application;
source elements deriving from GstBaseSrc will forward those downstream now.
- The DASH demuxer is now correctly parsing the MSPR-2.0 ContentProtection nodes
and emits Protection events accordingly. Applications relying on those events
might need to decode the base64 data stored in the event buffer before using it.
- The registry can now also be disabled by setting the environment variable
`GST_REGISTRY_DISABLE=yes`, with similar effect as the `GST_DISABLE_REGISTRY`
compile time switch.
- Seeking performance with gstreamer-vaapi based decoders was improved. It would
recreate the decoder and surfaces on every seek which can be quite slow.
- more robust handling of input caps changes in videoaggregator-based elements
such as `compositor`.
- Lots of adaptive streaming-related fixes across the board (DASH, MSS, HLS). Also:
- `mssdemux`, the Microsoft Smooth Streaming demuxer, has seen various
fixes for live streams, duration reporting and seeking.
- The DASH manifest parser now extracts MS PlayReady ContentProtection objects
from manifests and sends them downstream as `PROTECTION` events. It also
supports multiple Period elements in external xml now.
- gst-libav was updated to ffmpeg 3.3 but should still work with any 3.x
version.
- GstEncodingProfile has been generally enhanced so it can, for
example, be used to get possible profiles for a given file
extension. It is now possible to define profiles based on element
factory names or using a path to a `.gep` file containing a
serialized profile.
- `audioconvert` can now do endianness conversion in-place. All other
conversions still require a copy, but e.g. sign conversion and a few others
could also be implemented in-place now.
- The new, experimental `playbin3` and `urisourcebin` elements got many
bugfixes and improvements and should generally be closer to a full
replacement of the old elements.
- `interleave` now supports > 64 channels.
- this section will be filled in shortly
### OpenGL integration
- As usual the GStreamer OpenGL integration library has seen numerous
fixes and performance improvements all over the place, and is hopefully
ready now to become API stable and be moved to gst-plugins-base during the
1.14 release cycle.
- The GStreamer OpenGL integration layer has also gained support for the
Vivante EGL FB windowing system, which improves performance on platforms
such as Freescale iMX.6 for those who are stuck with the proprietary driver.
The `qmlglsink` element also supports this now if Qt is used with eglfs or
wayland backend, and it works in conjunction with [gstreamer-imx][gstreamer-imx]
of course.
- various `qmlglsrc` improvements
[gstreamer-imx]: https://github.com/Freescale/gstreamer-imx
- this section will be filled in shortly
## Tracing framework and debugging improvements
- New tracing hooks have been added to track GstMiniObject and GstObject
ref/unref operations.
- The memory leaks tracer can optionally use this to retrieve stack traces if
enabled with e.g. `GST_TRACERS=leaks(filters="GstEvent,GstMessage",stack-traces-flags=full)`
- The `GST_DEBUG_FILE` environment variable, which can be used to write the
debug log output to a file instead of printing it to stderr, can now contain
a name pattern, which is useful for automated testing and continuous
integration systems. The following format specifiers are supported:
- `%p`: will be replaced with the PID
- `%r`: will be replaced with a random number, which is useful for instance
when running two processes with the same PID but in different containers.
- this section will be filled in shortly
## Tools
- `gst-inspect-1.0` can now list elements by type with the new `--types`
command-line option, e.g. `gst-inspect-1.0 --types=Audio/Encoder` will
show a list of audio encoders.
- `gst-launch-1.0` and `gst_parse_launch()` have gained a new operator (`:`)
that allows linking all pads between two elements. This is useful in cases
where the exact number of pads or type of pads is not known beforehand, such
as in the `uridecodebin : encodebin` scenario, for example. In this case,
multiple links will be created if the encodebin has multiple profiles
compatible with the output of uridecodebin.
- `gst-device-monitor-1.0` now shows a `gst-launch-1.0` snippet for each
device that shows how to make use of it in a `gst-launch-1.0` pipeline string.
- this section will be filled in shortly
## GStreamer RTSP server
- The RTSP server now also supports Digest authentication in addition to Basic
authentication.
- The `GstRTSPClient` class has gained a `pre-*-request` signal and virtual
method for each client request type, emitted in the beginning of each rtsp
request. These signals or virtual methods let the application validate the
requests, configure the media/stream in a certain way and also generate error
status codes in case of an error or a bad request.
- this section will be filled in shortly
## GStreamer VAAPI
- GstVaapiDisplay now inherits from GstObject, thus the VA display logging
messages are better and tracing the context sharing is more readable.
- When uploading raw images into a VA surfaces now VADeriveImages are tried
fist, improving the upload performance, if it is possible.
- The decoders and the post-processor now can push dmabuf-based buffers to
downstream under certain conditions. For example:
`GST_GL_PLATFORM=egl gst-play-1.0 video-sample.mkv --videosink=glimagesink`
- Refactored the wrapping of VA surface into gstreamer memory, adding lock
when mapping and unmapping, and many other fixes.
- Now `vaapidecodebin` loads `vaapipostproc` dynamically. It is possible to
avoid it usage with the environment variable `GST_VAAPI_DISABLE_VPP=1`.
- Regarding encoders: they have primary rank again, since they can discover,
in run-time, the color formats they can use for upstream raw buffers and
caps renegotiation is now possible. Also the encoders push encoding info
downstream via tags.
- About specific encoders: added constant bit-rate encoding mode for VP8 and
H265 encoder handles P010_10LE color format.
- Regarding decoders, flush operation has been improved, now the internal VA
encoder is not recreated at each flush. Also there are several improvements
in the handling of H264 and H265 streams.
- VAAPI plugins try to create their on GstGL context (when available) if they
cannot find it in the pipeline, to figure out what type of VA Display they
should create.
- Regarding `vaapisink` for X11, if the backend reports that it is unable to
render correctly the current color format, an internal VA post-processor, is
instantiated (if available) and converts the color format.

## GStreamer Editing Services and NLE
- Enhanced auto transition behaviour
- Fix some races in `nlecomposition`
- Allow building with msvc
- Added a UNIX manpage for `ges-launch`
- API changes:
- Added ges_deinit (allowing the leak tracer to work properly)
- Added ges_layer_get_clips_in_interval
- Finally hide internal symbols that should never have been exposed
- this section will be filled in shortly
## GStreamer validate
- Port `gst-validate-launcher` to python 3
- this section will be filled in shortly
- `gst-validate-launcher` now checks if blacklisted bugs have been fixed on
bugzilla and errors out if it is the case
## GStreamer Python Bindings
- Allow building with msvc
- Add ability for the launcher to run GStreamer unit tests
- Added a way to activate the leaks tracer on our tests and fix leaks
- Make the http server multithreaded
- New testsuite for running various test scenarios on the DASH-IF test vectors
- this section will be filled in shortly
## Build and Dependencies
- Meson build files are now disted in tarballs, for jhbuild and so distro
packagers can start using it. Note that the Meson-based build system is not
100% feature-equivalent with the autotools-based one yet.
- Some plugin filenames have been changed to match the plugin names: for example
the file name of the `encoding` plugin in gst-plugins-base containing the
`encodebin` element was `libgstencodebin.so` and has been changed to
`libgstencodebin.so`. This affects only a handful of plugins across modules.
**Developers who install GStreamer from source and just do `make install`**
**after updating the source code, without doing `make uninstall` first, will**
**have to manually remove the old installed plugin files from the installation**
**prefix, or they will get 'Cannot register existing type' critical warnings.**
- Most of the docbook-based documentation (FAQ, Application Development Manual,
Plugin Writer's Guide, design documents) has been converted to markdown and
moved into a new gst-docs module. The gtk-doc library API references and
the plugins documentation are still built as part of the source modules though.
- GStreamer core now optionally uses libunwind and libdw to generate backtraces.
This is useful for tracer plugins used during debugging and development.
- There is a new `libgstbadallocators-1.0` library in gst-plugins-bad (which
may go away again in future releases once the `GstPhysMemoryAllocator`
interface API has been validated by more users).
- `gst-omx` and `gstreamer-vaapi` modules can now also be built using the
Meson build system.
- The `qtkitvideosrc` element for macOS was removed. The API is deprecated
since 10.9 and it wasn't shipped in the binaries since a few releases.
- this section will be filled in shortly
## Platform-specific improvements
### Android
- androidmedia: add support for VP9 video decoding/encoding and Opus audio
decoding (where supported)
- this section will be filled in shortly
### OS/X and iOS
### macOS and iOS
- `avfvideosrc`, which represents an iPhone camera or, on a Mac, a screencapture
session, so far allowed you to select an input device by device index only.
New API adds the ability to select the position (front or back facing) and
device-type (wide angle, telephoto, etc.). Furthermore, you can now also
specify the orientation (portrait, landscape, etc.) of the videostream.
- this section will be filled in shortly
### Windows
- `dx9screencapsrc` can now optionally also capture the cursor.
- this section will be filled in shortly
