  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • FFMPEG avi to streaming mp4

    29 mai 2013, par Vprnl

    I'm trying to get ffmpeg to encode various AVI files to mp4 for streaming purposes but my inexperience with the subject matter is making me doubt I'll ever get this to work.

    I use this commandline :

    ffmpeg -i test.avi -vcodec libx264 -r 24 -ac 2 -acodec ac3 -ab 128k -bt 240k -preset    fast -strict -2 -b:v 320K -bufsize 62000 -maxrate 62000 -movflags frag_keyframe+empty_moov test.mp4

    I use the " -movflags frag_keyframe+empty_moov" to make it possible to serve a fragmented mp4

    And this is the log I get :

    I hope someone can point me in the right direction. The goal is to serve the file to a html5 player. But sadly that has not yet worked.
    Thanks !

    [EDIT]

    Sorry if I'm being unclear. I have two issues. First FFMPEG gives me an error (as you can see in the log) but I'm uncertain why I get this error and secondly, the stream does not actually work. The tanscoding starts, but the player never receives the video

  • ffmpeg : mix audio and video of different length

    24 octobre 2016, par user3445678

    I have 2 files : 1 video file (without sound) - length 6 seconds, 1 audio - length 10 seconds.
    Both audio and video contains same conversation, but audio starts 4 seconds earlier and after that was started video.

    [----------] audio
    
    [------] video

    So, I want to mix them together to video file with length 10 seconds where first 4 seconds black screen with audio then goes real video and audio.

    [====------] audio+video (where '=' is black screen)

    I hope my description was clear enough ).
    How can I do this with ffmpeg or gstreamer ?
