  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
    L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

  • Is it possible to merge 3 videos with ffmpeg by -f concat and crossfade without video content

    10 août 2019, par user3792705

    I want to merge 3 .mov files quickly without losing any resolution. I want to be able to distinguish the 3 pieces of videos after merge.

    "ffmpeg -f concat" does not lose resolution and quick without crossfade.

    But, I can’t distinguish 3 videos.

    As far as I know ffmpeg filter can be used add crossfade, but it have to use video start/end content to do the merger, which might involve transcoding. It won’t be fast compared with ’concat’, which won’t do transcoding, but simply copying.

    Here is the content (ffmpeg -i video.mov) of one of 3 videos :

    If I don’t care about crossfade with video content, just some ’nice’ black screen in between (It would be nice I add some text, like date + time on the black screen) is good enough for me. Is it possible to do ’concat’ and simple crossfade without video ’content’ ?

  • FFMPEG fails to trim beginning of clip

    23 février 2020, par miguelmorin

    I have two .MTS files taken in sequence and I want to trim them to the first five seconds. This command works for the first file :

    ffmpeg -ss 0 -to 5 -i 00117.MTS -vcodec copy -acodec copy start_00117.MTS

    The result is 5 seconds and 17 MB, as opposed to the 12 minutes and 2 GB from the original.

    The same command on the second file fails :

    ffmpeg -ss 0 -to 5 -i 00118.MTS -vcodec copy -acodec copy start_00118.MTS

    The result is 12 minutes and 2 GB, like its original file.

    What is the problem ?

    Full log :

    $ rm start_00117.MTS; ffmpeg -ss 0 -to 5 -i 00117.MTS -vcodec copy -acodec copy start_00117.MTS
