When a Matroska Block is only stored in compressed form, the size of
the uncompressed block is not explicitly coded and therefore not known

During initialization of a v4l2m2m device, the configured pix_fmt can be
different to the pix_fmt of the encoder (i.e. avctx->pix_fmt).
For example on the Odroid XU4:
./ffmpeg -f lavfi -i yuvtestsrc -codec:v h264_v4l2m2m out.h264

Yes, I have other function need to use the mean and stdev which is
support in showinfo filter(only 8bit and don't support packed format,
no multi-thread), and signalstats

Thats nice but why is
You are duplicating some functionality of signalstats filter.

I have a file with audio in the format pcm_s16be. When I try to copy this audio
to another file using -c:a copy, it copies the audio but also transcodes it to
AAC.
If it's literally a copy, shouldn't the copy be pcm_s16be as well? How can I do
this and wind up with a pcm copy of the original aud

VP9 decoder should be able to handle resolution changing on inter
frame without re-initialization. For hardware decoder, re-allocate hardware
frame surface.
Fix #8068 for VA-API.

Request for comments.
This works for VA-API, however for dxva2 it didn't cover all cases
Doesn't change the logic, modify to keep it consistent with
7.3.8.8 in spec to avoid some misunderstandings.

Allow hw_frames_ctx to be recreated instead of just return if it exists.
Move hw_frames_ctx check outside ff_decode_get_hw_frames_ctx, and check
in relevant code.

Resolution/format changes lead to re-initialization of hardware
accelerations(vaapi/dxva2/..) with new hwaccel_priv_data in
the worker-thread. But hwaccel_priv_data in user context won't
be updated until the resolution changing frame is output.

It also generates .pb file which will be used by ffmpeg.
