  • ffmpeg converting .mkv to .264

    13 octobre 2015, par V. Panchenko

    I want to convert .mkv to .264.
    I try to do it using ffmpeg :

    ffmpeg -i input.mkv -vcodec copy -acodec copy output.264

    It works without errors, but when I try to play output.264 using ffplay :

    ffplay -f h264 -i output.264

    ffplay response is :

    14 janvier 2014, par user2914878

    I'm trying to add an audio file to a video file generated from images with FFmpeg.

    The command i am using on a Debian distrib is this one

    ffmpeg -r 1 -i edit%0d.jpg outputName.mp4 -i Test.mp3

    The video file is created but the audio is not working .

    On Windows it is working fine, i tried multiple scenarios but i can't seem to find the issue, maybe a codec problem ?

    Thank you !

    Update :

    I manage to fix it this way :

    ffmpeg -r 1 -i edit%0d.jpg -i Test.mp3 -ar 44100 -strict experimental
