  • MediaSPIP Core : La Configuration

  • Le plugin : Podcasts.

    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 ;

  • MP4Box / FFMPEG concat loses audio after first clip

    17 novembre 2017, par user1615343

    So I am certainly no expert when it comes to either of these tools, but I have a web-based project that’s executing commands on an Amazon Linux server to concatenate two video files that are uploaded.

    Both files are converted to mp4s first using FFMPEG, and those play perfectly in a browser after conversion :

    ffmpeg -i file1.mpg -c:v libx264 -crf 22 -c:a aac -strict -2 -movflags faststart file2.mp4

    Then, I attempt to combine these two resulting mp4s into a single mp4. I tried using FFMPEG to do this but to no avail. Switching to try MP4Box got me much closer : the videos are concatenated together, but the audio stops playing at the end of the first clip, and the second clip is silent.

    MP4Box -force-cat -keepsys -add file.mp4 -cat file2.mp4 out.mp4

    I’ve tried varying versions of the above command with no better results. Any input is greatly appreciated.

    EDIT : info on .mp4 files using

    ffmpeg -i file1.mp4 -i file2.mp4

    ffmpeg -i 1510189259715DogRunsintoGlassDoor_315a03a8e20acfc.mp4 -i
