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. -

GOP size for realtime video stream
7 janvier 2017, par MadMassI’m working on a kind of rich remote desktop system, with a video stream of the desktop encoded using avcodec/x264. I have to set manually the GOP size for the stream, and so far I was using a size of fps/2.
But I’ve just read the following on Wikipedia :This structure [Group Of Picture@ suggests a problem because the fourth frame (a P-frame) is needed in order to predict the second and the third (B-frames). So we need to transmit the P-frame before the B-frames and it will delay the transmission (it will be necessary to keep the P-frame).
It means I’m creating a lot of latency since the client needs to receive at least half of the GOP to output the first frame following the I frame. What is the best strategy for the GOP size if I want the smallest latency possible ? A gop of 1 picture ?

Passing FFmpeg encoder output to live 555 media server
23 septembre 2013, par AshutoshI need help on transmitting encoded output from encoder video output to live 555 media server.
ret=avcodec_encode_video2(c,&pkt,(AVFrame*)&sc_dst_data,&gotim);
source=ByteStreamMemoryBufferSource::createNew(*env,pkt.data,ret);
if (source == NULL){}
videoES = source;
video_source=H264VideoStreamFramer::createNew(*env,videoES);
video_sink->startPlaying(*video_source,afterPlaying, video_sink);The above codes doesn't transmit the streams properly.it breaks.any insights on how to do for a proper streaming in ffmpeg ?
Please help.
