  • 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 !

    Craig

  • Andriod streaming screen [closed]

    9 avril 2013, par blganesh

    Im able to share screen via ffmpeg

    But the output live stream is very slow.

  • Using FFMPEG to reliably convert videos to mp4 for iphone/ipod and flash players

    23 avril 2016, par Jake Stevenson

    I need to convert videos for use in both a flash player and the iphone/ipod touch. I’m using the following batch script with ffmpeg :

    @echo off
    ffmpeg.exe -i %1 -s qvga -acodec libfaac -ar 22050 -ab 128k -vcodec libx264 -threads 0 -f ipod %2

    This always outputs an mp4 file, and I can always play it on my PC. The videos also seem to play fine on my iphone 3GS. But with some input files it won’t work for older iphone versions (3G and iPod touch).

    Here’s the ffmpeg output from one such file :

    My suspicion is that it has something to do with the audio encoding. If so, does anyone know how to force it to reencode the audio to the proper format ?

    Any other ideas ?
