Vous pouvez utiliser la liste de discussion de développement afin de le faire savoir ou demander de l’aide quant à la réalisation de ce plugin. MediaSPIP étant basé sur SPIP, il est également possible d’utiliser le liste de discussion SPIP-zone de SPIP pour (...) -
Menus personnalisés
14 novembre 2010, parMediaSPIP utilise le plugin Menus pour gérer plusieurs menus configurables pour la navigation.
Cela permet de laisser aux administrateurs de canaux la possibilité de configurer finement ces menus.
Menus créés à l’initialisation du site
Par défaut trois menus sont créés automatiquement à l’initialisation du site : Le menu principal ; Identifiant : barrenav ; Ce menu s’insère en général en haut de la page après le bloc d’entête, son identifiant le rend compatible avec les squelettes basés sur Zpip ; (...) -
Possibilité de déploiement en ferme
12 avril 2011, parMediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...)

How can I stream mjpeg file as rtsp
24 août 2013, par Ilya YevlampievWe have an mjpeg video, obtained from the webcam and stored into *.avi file, still encoded as mjpeg.
We need to restream this file as rtsp (and stil preserve the mjpeg there, i.e. no decoding). The goal is to emulate the webcam this video was obtained from for the software that processes the video. The file can be open with vlc/ffplay with no problems. The ffmpeg behaves like it is streaming it, however, ffplay/vlc can't open this stream.
We tried to stream if with gstreamer.
1) we fount no free rtsp sink element for gstreamer pipeline. So, is there a free analogue for rtspsink to launch this pipeline with gst-launch ? we need and only cast, so we don't need so advanced element as rtspsink is.
2) we also tried to build own simple rtsp server as described in http://weeklybuild.com/2013/01/creating-an-rtsp-stream-with-gstreamer/
replacing videotestsrc with filesrc ; but what kind of elements we should use there ? usage of an only filesrc doesn't help ; we get the same problem as if we stream with ffmpeg. But what kind of lements we need there, if we dont' wan to decode/encode it, just to stream the file (to reproduce the thing what the webcam actually does).

FFmpeg stops encoding after x minutes when using Mjpeg
31 janvier 2018, par Rune AspvikI’m using ffmpeg in a node application with this command :
ffmpeg -seekable 0 -i http://127.0.0.1:8100/Mjpeg/1?authToken=xxx -video_size 1280x720 -r 30 -pix_fmt yuv420p -y D:\Video\pflyers\test.mp4
The encoding would stop after 28:53 every time. After some reading I figured I had to spawn the child instead of exec because of the large sterr output.
Before doing that I wanted to see if that was in fact the issue so I tried doing :
-nostats -hide_banner -loglevel panic
to avoid the large output to sterr. FFmpeg still stopped after 28:53. Further I tried to write the sterr to log.txt instead of using the above code. I did so adding this to the end :
2> log.txt
Still it would stop at 28:53.
Finally I tried running the command in cmd.exe resulting in the encoding stopping at 29:14.
What I realized comparing the outputs from ffmpeg run from node and run from cmd.exe was that the encoding stopped when the log.txt reached 388kB.
How can I fix this ?
Here’s the full output :
C:\Users\VossVind>ffmpeg -seekable 0 -i http://127.0.0.1:8100/Mjpeg/1?authToken=xxx -video_size 1280x720 -r 30 -pix_fmt yuv420p -y D:\Video\pflyers\test.mp4
