  • 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.
    Version mono serveur
    La version mono serveur consiste à n’utiliser qu’une (...)

  • How to transcode HLS video (with .m3u8 subtitle file) for MPEG-DASH stream using FFMPEG ?

    15 mai 2017, par Toan Tran

    I’m trying to use ffmpeg to transcode a HLS video.m3u8, which uses a .m3u8 subtitle file, for MPEG-DASH streaming. The subtitle file has been defined in the master manifest video.m3u8 but I receive only the video and audio, the subtitle doesn’t come along. What am I doing wrong ? Your help is very much appreciated.

    This is the command I used :

    ffmpeg -i http://myserver_ip/video.m3u8 -vcodec libx264 -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1 -f flv rtmp://myserver_ip/dash/SampleVideo

    This is my video.m3u8 master manifest file :

  • FFMPEG - VP9 - Fail to create DASH manifest file

    Can’t create manifest.mpd file with FFMPEG.
