• H264 Encoding - Could not play video using VLC Player

  31 mars 2016, par bot1131357

  I am have trouble encoding an H264 video correctly using FFmpeg libav. I could not play the encoded video in VLC media player, and although I could play the video on MPC-HC the time shows 00:00/00:00. Clearly I’m missing something.

  The Media info from MPC-HC shows this :

  I noticed something odd in the above info :
   The frame rate is 20.833 fps, instead of the specified 10 fps.
   Duration of 2s 400ms did not seem right either, since the video played for more than 4s.

  Also, (AVFrame* picture)->pict_type is always set to AV_PICTURE_TYPE_NONE. I don’t think this is normal.

  The library that I’m using is ffmpeg-20160219-git-98a0053-win32-dev. I would really really appreciate if you could help me out of this confusion.

  On another machine I can open the flv-stream via VLC by opening the address http://ip.running.ffserver:8090/live.flv.

  So why does it works step by step via the movie.flv file and not directly ?

  What is the difference between

  • avconv -f mjpeg -i movie.mjpg -r 20 -b 2000k -vcodec libx264 -preset ultrafast -f flv -metadata streamName="mjpeg_to_flv" -metadata title="converting mjpeg to flv via avconv" movie.flv
    followed by
    ffmpeg -stream_loop -1 -i movie.flv http://localhost:8090/feed1.ffm and

  • avconv -f mjpeg -i movie.mjpg -r 20 -b 2000k -vcodec libx264 -preset ultrafast -f flv -metadata streamName="mjpeg_to_flv" -metadata title="converting mjpeg to flv via avconv" http://localhost:8090/feed1.ffm ? Why ends this command with a av_interleaved_write_frame(): Connection reset by peer ?
