Fixes #7410.
The value of sub-pixel precision for me/mc can change during an Intra frame. In
multi-threaded decoding this change is not propagated to other frame threads
causing decoding artifacts. This patch initializes the sub-pixel precision
parameter from previous thread, which fixes the

Hello,
I've been working with HEVC + mpegts at low bitrates 10-20kbps.
At these bitrates, mpegts can create a substantial overhead due
to the 188 byte frame size (i.e. a NAL unit of 200 bytes will get
rounded up to 376 bytes).
I've tried to get around this by concatenating multiple NAL

Fixes Ticket #7895.
Currently, timestamp interpolation is disabled by default in H264 and
HEVC. This creates playback issues when the demuxer does not output a
valid timestamp. This patch allows interpolation when no b-frames have
been observed during decoding, which fixes

Currently, the mp4toannexb filter always inserts the same extradata at

decoding errors if modified parameter sets are signalled in-band.

This patch avoids a read past the end of the input buffer in memcpy since the
size
of the received zmq message is recv_buf_size - 1.

Changes in v2:
1. Replaced zmq_poll with zmq_msg_recv.
2. Remove user timeout option as zmq_msg_recv(.., .., ZMQ_DONTWAIT) is a
non-blocking call.
3. Updated docs.

Fixes #7799
Currently, the mp4toannexb filter always inserts extradata at the start
of each IRAP unit. This can lead to duplication of parameter sets if the
demuxed packet from mdat atom already contains a version of the
parameters.
As in ticket #7799 this can also lead
From: Andriy Gelman
Since reading 4 bits always returns a value in the range [0, 15], the
check for vps_id >= HEVC_MAX_VPS_COUNT, where HEVC_MAX_VPS_COUNT = 16, is
redudant.

Fixes #7799
Currently, the mp4toannexb filter always inserts the same extradata at
the start of the first IRAP unit. As in ticket #7799, this can lead to
decoding errors if modified parameter sets are signalled in-band.
This commit keeps track of the VPS/SPS/PPS parameter
From: Andriy Gelman
Test hevc-mp4annexb-pps:
Test contains 64 PPS that are signalled in extradata.
Different PPS are referenced by the VCL nal units during the mp4 to
annexb conversion.
Test hevc-mp4annexb-sps:
Access units contain PPS that reference different cached SPS nal
units.

tests
Changes to v5:
- Remove -y from new fate tests so that they are in the same format as other
md5 tests. And removed proposed change to existing fate test.

Since the original extradata is in HVCC format, there is no need to
segment the output extradata into nal units.

This allows the user to set a maximum number of buffered packets when

Before this commit an av_assert0 would fail if a v4l2 device did not
support a target format.
For example,
./ffmpeg -f v4l2 -codec:v h264 -i /dev/video0 -f mpegts -
would signal an abort if /dev/video0 did not support h264.
The new behaviour is to return an AVERROR(EINVAL

Currently an av_assert0 is triggered when a target format is not
supported by a v4l2 device. Replace by av_assert1 to fix this issue.
Fixes #6629.

This commit removes an av_assert0 which signals an abort when a v4l2 device
does not support a target format.
For example:
./ffmpeg -f v4l2 -codec:v h264 -i /dev/video0 -f mpegts -
will currently signal an abort if /dev/video0 does not support h264.
