Les statuts des instances de mutualisation
13 mars 2010, parPour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.

ffmpeg live rtmp stream does not start to process for long time
10 août 2013, par user1492502I have rtmp stream created by flash player in h264 but when i convert it to video or tumbnail using ffmpeg it some times works after very very long time and some time not work but if I create a stream with Flash Media live encoder on same FMS server the command below works fine. At the same time if I try the stream in player it works well and fine.
I am using IP so DNS resolving issue is not possible either I think.
ffmpeg -i rtmp ://xxx.xxx.xx.xx/live/bdeef2c065509361e78fa8cac90aac741cc5ee29 -r 1 -an -updatefirst 1 -y thumbnail.jpg
Following is when it worked aftre 15 - 20 minutes
ffmpeg -i "rtmp://xxx.xxx.xx.xx/live/bdeef2c065509361e78fa8cac90aac741cc5ee29 live=1" -r 1 -an -updatefirst 1 -y thumb.jpg

Frame rate very high for a muxer not efficiently supporting it
23 avril 2014, par DevDaveI got an error when trying to run the following command with FFMpeg :
-i "file1.mp4" -s 506x406 -b:v 2000k -ar 22050 "file2.mp4"
FFMpeg was stuck converting this video, which was just a 7Mb .mp4 file, for hours and eventually I had to kill the process.
The output error from FFMpeg is as follows :
