MediaSPIP 0.1 Beta version
25 avril 2011, parMediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
The zip file provided here only contains the sources of MediaSPIP in its standalone version.
To get a working installation, you must manually install all-software dependencies on the server.
If you want to use this archive for an installation in "farm mode", you will also need to proceed to other manual (...) -
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. -

C - Transcoding to UDP using FFmpeg ?
30 avril 2013, par golmschenkI'm trying to use the FFmpeg libraries to take an existing video file and stream it over a UDP connection. Specifically, I've been looking at the muxing.c and demuxing.c example files in the source code doc/example directory of FFmpeg. The demuxing file presents code which allows an input video to be converted into the video and audio streams. The muxing file presents code which creates fake data and can already be output to a UDP connection as I would like. I've begun work combining the two. Below can be found my code which is basically a copy of the muxing file with some parts replaced/appended with parts of the demuxing file. Unfortunately I'm running into plenty of complications attempting my goal through this approach. Is there an existing source code example which does the transcoding I'm looking for ? Or at least a tutorial on how one might create this ? If not, at least a few pointers might be helpful in directing my work in combing the two files to achieve my goal. Specifically, I'm getting the error :
[NULL @ 0x23b4040] Unable to find a suitable output format for 'udp://localhost:7777'
Could not deduce output format from file extension: using MPEG.
Output #0, mpeg, to 'udp://localhost:7777':Even though the muxing file could accept UDP formats. Any suggestions ? Thank you much !

Android AudioRecord to FFMPEG encode native AAC
8 mars 2013, par Curtis KiuI am doing video chatting in android and i would like to port ffmpeg to stream rtsp or rtmp but now i have a try in RTSP first.
Somehow the problem now is av_write_frame or av_interleaved_write_frame is fail to work or just crash.
Maybe...
AudioRecord Sample format is not equals to FFMPEG setting
Frame receive is not equalsSo code... AudioRecorder
