  • Multilang : améliorer l’interface pour les blocs multilingues

    18 February 2011, by

    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.

  • Strange "pause" in video after concatenation of two mp4 videos

    3 October 2016, by user606521

    I am concatenating two mp4 videos. The problem is that first video (intro.mp4) lasts 5 seconds, second video (output.mp4) lasts 2 seconds and video created by concatenating them lasts 9 seconds (and should last 5+2 = 7 seconds). In final.mp4 video the last frame from first video (intro.mp4) i shown for additional 2 seconds before second video (output.mp4) is played. It looks like a lag when watching video. What I am doing wrong?

    list.txt:

    file 'data/intro.mp4'
    
file 'output.mp4'

    command:

    ./bin/ffmpeg -f concat -i list.txt -c copy final.mp4

    output:

  • Get correct framerate from ffmpeg

    20 September 2015, by user3249421

    Good day,

    I have a problem. I need get correct framerate from ffmpeg libs..

    I tried use

    pFormatCtx->streams[videoStream]->avg_frame_rate.num

    return of avg_frame_rate is 2997. But when I dumped meta info, I got:

    Input #0, avi, from '/test.avi':

    sample rate is: 23.98fps. What value is correct and why are they different?
