  • FFMEPG - How to resolve 'Reinit context to WxH ... deprecated pixel format'

    30 juin 2022, par hi im Bacon

    I am using the pyav library to read and process video data and as I am reading through the videos I am getting lots (and lots) of the following output.

    


    I am creating the videos by segmenting either a much larger source file or RTSP/HTTP IP camera.

    


    I would love to understand what this output actually means, and what I can do to prevent its output

    


    ffmpeg creating videos :

    


    ffmpeg -y -i https://manifest.googlevideo.com/api/... -pix_fmt yuvj422p -c:v libx264 -an -vf scale='min(1280,iw)':'min(720,ih)':force_original_aspect_ratio=decrease -r 12 -vsync cfr -x264opts keyint=12:min-keyint=12 -f segment -segment_format matroska -segment_time 5 -initial_offset 1656497474.686672 -strftime 1 /tmp/tmp87cc1n2o/%Y-%m-%dT%H%M%S.mkv -loglevel error


    


    python :

    


    container = av.open(io.BytesIO(...))
for frame in container.decode(video=0):
