Libx264 uses strtok which is not thread safe. Strtok is used in
x264_param_default_preset in param_apply_tune in x264/common/base.c.
Therefore the flag must be removed.

x264 fixed the issue, once the fix is pushed to stable, an #if can be added
to re-enable the flag based on X264_BUILD number.

Fixes ticket #7446.

Revert "avcodec/decode: copy the output parameters from the last bsf in the chain back to the AVCodecContext"

This reverts commit f631c328.

The avcodec_parameters_to_context() call was freeing and reallocating
AVCodecContext->extradata, essentially taking ownership of it, which according
to the doxy is user owned. This is an API break and has produced crashes in
some library users like Firefox[1].

Revert until a better solution is found to internally propagate the filtered
extradata back into the decoder context, or a decision is made to change the
API.

This has no visible effects but I happened to run under the cuda
memcheck tool and it called it out as an error.

Several SRT options are missing. Since pkg_config requires libsrt v1.3.0 and above, it should be able to support options added in libsrt v1.3.0 and below.
This commit adds 8 SRT options.
sndbuf, rcvbuf, lossmaxttl, minversion, streamid, smoother, messageapi and transtype
The keys of option are equivalent to stransmit.

Allows arrangement of multiple windows such as:
ffmpeg -re -f lavfi -i mandelbrot -f sdl -window_x 1 -window_y 1 mandelbrot -vf waveform,format=yuv420p -f sdl -window_x 641 -window_y 1 waveform -vf vectorscope,format=yuv420p -f sdl -window_x 1 -window_y 481 vectorscop

Some changes by Marton Balint:
- allow negative position (partially or fully out-of-screen positions seem to
  be sanitized automatically by SDL (or my WM?), so no special handling is
  needed)
- only show window after the position is set
- do not use resizable and borderless flags at the same time, that caused
  issues in ffplay
- add docs

Create SMPTE ST 12-1 timecodes based on H.264 SEI picture timing
info.

For framerates > 30 FPS, the field flag is used in conjunction with
pairs of frames which contain the same frame timestamp in S12M.
Ensure the field is properly set per the spec.

Currently qsv (m)jpeg encoding is broken.
Regression introducing by the commit(id: c1bcd3): fix async support,
which requires the minimum async_depth to be 1, instead previous zero.
But the default async_depth of qsv (m)jpeg encoding is still initialized
(mostly) as zero.

This patch also abviously improves qsv (m)jpeg encoding performance
due to the default async_depth is changed to 4.

Any of these buffers (for both H.264 and H.265) might reasonably be
parsed using the bitstream reader, so include padding on all of them.

It should be the same as the one used for the rest of the pic_timing
structure.

64c50c0e declared support for decomposing
them but omitted to implement it; this adds an implementation.

Also do the same for end-of-stream NAL units, since they are equivalent.

There are different the RCV file format for VC-1, vc1test
just handle the case 2 now, this fix will support the case 1.
(Both of test clips come from: SMPTE Recommended Practice -
VC-1 Decoder and Bitstream Conformance). And I think I got
a older VC-1 test clip in the case 1.

It's not used, and pulls in the ffnvcodec header, which does not neccesarily have to exist to build these filters, since they include the full cuda.h.
