    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 (...)

  • How to replace the video track in a video file with a still image ?

    22 février 2021, par cornerstore

    I am trying to use ffmpeg to replace the video track in a video file with a still image. I tried some commands I got from other questions such as the one here

    


    ffmpeg -i x.png -i orig.mp4 final.mp4

    


    ffmpeg -r 1/5 -i x.png -r 30 -i orig.mp4 final.mp4

    


    But these didn't work. I'm not sure which of these arguments are required or not. The output should be accepted by YouTube as a valid video - I was able to simply remove the video track, but apparently they don't let you upload a video without a video track.
