Sometimes, one wants to force a clock on some pipelines - for instance,
when testing TSN related pipelines, one usually uses GstPtpClock or
CLOCK_REALTIME (assuming system realtime clock is in sync with network
one). Until now, one needs to write an application for that - not
difficult, but quite boring if one just wants to test something. This
patch presents a new element to help that: clockselect.
clockselect is a pipeline with two properties to select a clock. One
property, "clock-id", enables one to choose between "monotonic",
"realtime", "ptp" or "default" clock - where default keeps pipeline
behaviour of choosing a clock based on its elements. The other property,
"ptp-domain" gives one the choice of which PTP domain should be used.
Some very simple tests also added for this new element.
By passing NULL to `g_signal_new` instead of a marshaller, GLib will
actually internally optimize the signal (if the marshaller is available
in GLib itself) by also setting the valist marshaller. This makes the
signal emission a bit more performant than the regular marshalling,
which still needs to box into `GValue` and call libffi in case of a
generic marshaller.
Note that for custom marshallers, one would use
`g_signal_set_va_marshaller()` with the valist marshaller instead.
The peer is already gone when pad_removed_cb() called, so the ghost cannot
be removed. Use g_object_set_data() instead to remember the ghost pad.
Copied from similar code in GstRTPBin.
Since we are not requiring that profile equals GST_JPEG2000_PARSE_PROFILE_BC_SINGLE,
(as the standard requires) we can allow profile to be null. We relax this condition because
OpenJPEG can't create broadcast profiles.
1. only recalculate src codec format if sink caps change
2. use correct value for "jp2c" magic in J2C box ID
3. only parse J2K magic once, and store result
4. more sanity checks comparing caps to parsed codec
It provides to set tile-columns and tile-rows configurations. The av1
codec allows an input image frame be partitioned into separate vertical
or horizontal tile which can be encoded or decoded independently. It
helps to encode/decode parallel.
CURLOPT_DEBUGFUNCTION option replaces the standard debug function
used when CURLOPT_VERBOSE is in effect. This callback receives various debug information.
In future, a sub class of GstMsdkEncClass may decide a native format by
using this method, e.g. JPEG encoder may accept YUY2 input, however the
current implemation needs a conversion from YUY2 to NV12 before encoding.
In addtion, a sub class may choose a format for encoding if the input
format is not supported by MSDK, e.g. the current implemation does
UYVY->NV12 if the input format is UYVY. We may do UYVY->YUY2 for JPEG
encoder in future
MFX_FOURCC_BGR4 is mapped to VA_FOURCC_ABGR and JPEG encoder needs a
MFX_FOURCC_BGR4 frame for internal usage when the input format is
MFX_FOURCC_RGB4
This is a preparation for supporting native formats of JPEG encoder
This adds two properties:
* scte-35-pid: If not 0, enables the SCTE-35 support for the current
program. This will write the proper PMT and send SCTE-35 NULL
commands (i.e. heartbeats) at a regular interval
* scte-35-null-interval: This specifies the interval at which the
NULL commands should be sent
Sending SCTE-35 commands is done by creating the appropriate SCTE-35
GstMpegtsSection and then sending them on the muxer. See the
associated example
We were unconditionally adding top-level descriptors in the PMT which
were only related to bluray support for PS3 (from 10 years ago).
These should be re-added conditionally
This went un-noticed for 6 years :( The issue is that for short
sections (without subtables and CRC), we would always fail when
checking whether we had enough data or not and then default to the
long section checking.
Use the long section checking would then cause interesting side-effects
for short sections (such as believing they were already seen and therefore
would be dropped/ignored).
Instead of using a proxy of `is_packetized` flag this patch
replaces it with the accessor to that flag in decoder base class,
avoiding probable mismatches.
commit 55c0d720 added the capability to handle non-packetized bitstream,
and there is a loop to handle multiple frames in a non-packetized buffer
in gst_msdkdec_handle_frame. However it is possible that a
non-packetized buffer still contains valid data but there is no long any
pending unfinished frame. Currently gst_video_decoder_decode_frame is
invoked to send a new frame with new input data, the situaltion is
repeated till an EOS is received. An application has to exit when
receiving an EOS, however there is still valid data in a
non-packetezied input buffer, hence some frames are dropped.
This fix adds a parse callback for non-packeteized input, a new frame
will be sent to the subclass as soon as the input buffer has valid data
This fixes https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/665
And only update the caps and stream-start event accordingly. This
ensures that we'll always forward sticky events that arrive after the
caption pad was created, and especially updates to existing sticky
events like the segment event.
Also create a proper stream id based on the upstream stream id for the
stream-start event, and make sure that all the sticky events we know are
already on the caption pad at the time it is added to the element.
clamp-to-border will return the border color which is typically black,
white or transparent. When linear filtering the edge pixels will
typeically be combined with the border color which is not typically what
we want. Especially when color converting, this removes a green box
around the edge when converting YUV->RGB.
This fixes a regression from commit "srtp: Support libsrtp2"
e9aa117200 where an internal
set of ssrc(s) was added because the libsrtp v2 keeps its
internal streams as private. But the change prevented that
ssrc(s) that not in the caps from being added to the stats.
This patch ensures that all ssrc(s) are inserted to this set
instead of only inserting those from the caps.
