  • failed to converted raw H264 to mp4 wiht FFMPEG and playback it

    27 décembre 2015, par Efimk

    I am trying to convert raw video file captured from Cisco EX60 to valid MP4 file.
    I use the following command
    ffmpeg -f rawvideo -pix_fmt yuv420p -s:v 1920x1080 -r 25 -i input2 -vcodec libx264 output2.mp4

    and get

    When I use just
    ffmpeg -f h264 -i input -vcodec copy -r 25 outfile.mp4
    It replace initial IFrame with B-frames so I cannot playback it. I can view it with VCL, but not with Windows Media player, for example.
    What is wrong with the command ?
