Qualité du média après traitement
21 juin 2013, parLe bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...) -

Les tâches Cron régulières de la ferme
1er décembre 2010, parLa gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
Le super Cron (gestion_mutu_super_cron)
Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement.

Can not add tmcd stream using libavcodec to replicate behavior of ffmpeg -timecode option

Yet another ffmpeg/libx264 issue
26 décembre 2013, par kerim yucelMy current situation is ; ffmpeg and libx264 has been compiled for Android, as shared and static libraries respectively. Since I have libx264.a and libffmpeg.so with me, only thing that remains is to link them and obtain a ffmpeg library that would allow me to proceed with my application. However, some questions remain unanswered. I am using Ubuntu with a virtual machine under Windows 7. I am using x264’s last version, ffmpeg 0.10.4 release and NDK 7.
I have tried to adjust flags (extracf and extrald) in order to include libx264 to ffmpeg compilation process as well, however I keep failing. Below you may find my build script for ffmpeg and the errors I have encountered.

/home/mehmet/Android_NDK_r7b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-ar: creating libavcodec/libavcodec.a
/home/mehmet/Android_NDK_r7b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/bin/arm-linux-androideabi-ld: cannot open output file ./androidIncludeTrialsNDK7/armv7-a/libffmpeg.so: No such file or directoryI have x264 installed in my directory /home/mehmet/x264 and I also check whereis x264.a, it shows me as /usr/local/lib. I have tried changing the path $x264 to point out to home/mehmet/x264 folder, but I get the same error.
Lastly, if I enable both extracf and extrald flags ( both commented ones and the used ones) . I get the same error mentioned above. I am afraid I am doing a simple typo here, but can`t see it and it is driving me crazy. Thanks a lot for your help.
Best.
EDIT
I have deleted the comments and now obtain the following.
