[FFmpeg-devel] [PATCH v2] avcodec/cuvidddec: Guess pixel format based on probed bit depth and chroma sampling

[Roman Arzumanyan]

Thanks a lot Timo !

Just for my own education: in my application I follow the usual sequence of
API calls to init hw device context and open the codec. What's the right
place to probe the input? I was under the impression that it's done within
avformat_find_stream_info().
