Comment (by JEEB):
Replying to [comment:3 cehoyos]:
> Did you transcode the input file with vlc? If not, the comparison makes
little sense (vlc does suppport transcoding).
Could you please note why you think transcoding/non-transcoding is
relevant in this case? The issue is just being replicated through ffmpeg.c
as that is the simplest way to utilize FFmpeg's internal tooling as a way
of reproduction for an issue ticket. It is also visible in another
application utilizing VT through the the FFmpeg hwaccel interface.
This can be a difference in the VT API usage between VLC's and FFmpeg's
hwdec interfaces, yes. If that is what you are pointing towards, I would
note that mentioning it in this way is with quite the detour (at least in
my opinion).
