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.
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. -
L’agrémenter visuellement
10 avril 2011MediaSPIP est basé sur un système de thèmes et de squelettes. Les squelettes définissent le placement des informations dans la page, définissant un usage spécifique de la plateforme, et les thèmes l’habillage graphique général.
Chacun peut proposer un nouveau thème graphique ou un squelette et le mettre à disposition de la communauté.

Getting either incorrect output resolution or FPS from ffmpeg
5 novembre 2011, par AdamI am capturing an RTSP stream from a security camera, and transcoding it for (live streaming) to iphone, using OSX as the encoding platform.
I have it working correctly, and Im tuning it.
However, it seems that it is not outputting the requested resolution. This is my script/Applications/SecurityCamera/openRTSP -v -c -t rtsp://10.0.1.118/ch1-s1 | \

Stream mapping:
Stream #0.0 -> #0.0You can see that its working, but it is outputting 1600x1200 for some reason. (possibly
-vcodec copycopies all codec parameters, not just the codec type ?)If I change the
-vcodec copyto-vcodec libx264then I get the correct status report (stating 960x640, correct), but the streaming switches to 2 FPS (why ? Im forcing both input and output !) and it halts after 54 frames (see output below)Seems stream 0 codec frame rate differs from container frame rate: 20.00 (20/1) -> 10.00 (20/2)
