Package: ffmpeg
Version: 7:4.0.2-2+b1
Severity: normal
Dear Maintainer,
* What led up to the situation?
I am just following the FFmpeg wiki
https://trac.ffmpeg.org/wiki/Hardware/VAAPI, and things are not working as
documented.
* What exactly did you do
I first tried the simplest one which should "allows the decoder to work
standlone to make decoding faster without any additional options", then I tried
to feed the vaapi pixfmt to a vaapi encoder, but both are not working (see
below)
* What was the outcome of this action?
For the first one:

They should work...

The input is a short video cut in h264. Hardware decoding looks fine:

Thanks for checking. I guess it's one of the cases where encoding does
not work because of the non-free shaders we had to remove for the
version in main.
Cheers
