Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.

webm to mp4 conversion using ffmpeg
2 décembre 2015, par Pavan KWhen I try to convert a webm file to mp4 the output is very very choppy and it appears as if many frames have been dropped by ffmpeg
I used the following commands to convert
ffmpeg -i movie.webm movie.mp4
ffmpeg -i movie.webm -vcodec libx264 movie.mp4
ffmpeg -i movie.webm -vcodec libx264 -qscale 0 movie.mp4All of them have the same problem. When I use ffprobe it seems to show the frames more or less properly.
