  • Support audio et vidéo HTML5

    10 avril 2011

  • No audio encoded with ffmpeg using webm/libvorbis

    15 mars 2013, par Craig Lillard

    Having issues getting audio to encode to webm. Tried many different methods and it just ain't happenin. The commands are printed below before each pass.

    I have tried moving the audio commands around, trying different bitrates, different audio commands and have tried it on a couple of different files as well that both have audio.

    Encoding these files to MP4 using x264 causes no problems and works just fine and the audio plays, so it appears to be an issue just with webm. As you can see below, it is a 2-pass encode.

    Thanks for any help you can provide !

  • Why does FFMPEG always make large WebM files ?

    2 avril 2013, par Student of Hogwarts

    I'm trying to encode my movies into WebM :

    ffmpeg -i input.MOV -codec:v libvpx -quality good -cpu-used 0 -b:v 10k
    -qmin 10 -qmax 42 -maxrate 10k -bufsize 20k -threads 8 -vf scale=-1:1080
    -codec:a libvorbis -b:a 192k
    output.webm

    I want to encode at a couple of different bit rates (video and audio combined) :

    • 2192 kbps
    • 1692 kbps
    • 1000 kbps

    The problem is that no matter which bit rates I enter, I always get a file with a bit rate higher than 1900 kbps. (1914 kbps with the code example above.)

    What am I doing wrong ?
