Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ; -
Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.
Version mono serveur
La version mono serveur consiste à n’utiliser qu’une (...) -

java.lang.ExceptionInInitializerError in FFmpeg Test
22 janvier 2013, par Mehul RanparaI have a demo called FFMpegTest of Android which i downloaded from here..https://github.com/appunite/AndroidFFmpeg..and i also have Library file of FFMpeg which is in this demo and i am using this Library in FFmpegTest..Now when i running..it gives java.lang.ExceptionInInitializerError.. Anyone have an idea about this..please share with me..Thanx in Advance..

Compile ffmpeg arm with libx264 and opencore-amr support
10 janvier 2013, par bruxI am trying to build ffmpeg for Android with libx264 and amrnb/wb support. I have followed the instructions here :
http://dl.dropbox.com/u/22605641/ffmpeg_android/main.html
I then installed opencore-amr from github and also found the opencore-amr-devel package, when I try to build ffmpeg I always get an error :
ERROR : libopencore_amrwb not found
Has anyone managed to buid ffmpeg-arm with libopencore-amr support ?

ffmpeg : images to 29.97fps mpeg2, audio not sync [migrated]
21 novembre 2011, par Andy LeI have spent a lot of time on this issue. Hope someone can help.
I want to convert 3147 images + ac3 audio file into an mpeg2 video at 29.97fps (about 1m45s). My command :
~/ffmpeg/ffmpeg/ffmpeg -loop_input -t 105 -i v%4d.tga -i final.ac3 -vcodec mpeg2video -qscale 1 -s 400x400 -r 30000/1001 -acodec copy -y out.mpeg 2> out.txtHowever, the audio file ends before the frame sequence. Which means the video is slower then audio.
I checked the output file with imageinfo and see :
