  • 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 error trying to create mpeg video

    18 juin 2012, par Eamonn McEvoy

    I am having trouble creating mpeg files, I have 2 bitmaps (2592*2160 32bit). I am trying to combine them into an mpeg file but I cant get it to work, the command I have tried is :

    ffmpeg -i %d.bmp -b:v 99.99M -r 1 -s 2592x2160 vid.mpg

    the output is

    ffmpeg -i %d.bmp -b:v 99.99M -r 1 -s 2592x2160  vid.mpg

  • Limitations of ffmpeg ?

    7 février 2016, par Eamonn McEvoy

    I am trying to convert an avi file to mpeg, but ffmpeg is giving me these error messages, ’buffer underflow’ and ’packet too large’

    The command I am using is :

    ffmpeg -I input.avi -s 2592x2160 -b 1200 output.mpg

    1. Dimensions of video - are there any limitations ?

      I have noticed that if I take a video with smaller dimensions it seems to work ok, Is there any way to accommodate files with large dimensions like this ?

    2. Frame rate - can ffmpeg pad out videos ?

      I also have issues with certain frame rates, the error message tells me that only certain frame rates are supported by the mpeg1 format, can I get ffmpeg to pad out my avi file to account for this ?

    3. File size - are there any limitations on the max file size that can be converted ?

    Thanks,
    Eamonn
