    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • ffmpeg - merge mp3 and mp4 (duration difference)

    8 décembre 2017, par dfionov

    I’m trying to merge mp4 and mp3 files with ffmpeg.
    mp4 duration - 9.800 sec, mp3 - 58.540 sec. So i using -shortest key.
    Code :

    ffmpeg -i video.mp4 -i audio.mp3 -c:v libx264 -c:a aac -strict experimental -shortest output.mp4

    After that i got output.mp4 with duration 9.846. Where is my error ? Why output video longer than source ? (9.846 sec and 9.800 sec).

    So as per the indications of this thread ffmpeg : convert audio-only flv to swf I ran the command sudo apt-get install ffmpeg libavcodec-extra-52
    to install the extra libraries and i still have the same issue. Any other ideas ?

    UPDATE : also in the thread they link to this site to make it work http://stephenjungels.com/jungels.net/articles/ffmpeg-howto.html followed all the steps and it still won’t work
