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.
Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...)

FFplay requesting video via RTSP :// but receiving on multicast address
28 mai 2014, par DavidGFirst of all, I apologize for how long the supporting information will be in this post. This is my first post on this forum.
My issue is I need to run the command line version of ffmpeg to capture a video stream. However, as a proof of concept I’m first attempting to capture and view the video using ffplay (BTW, I have not had any success using ffmpeg or ffprobe). I’m running the ffplay command to read video from a Coretec video encoder which has multicast enabled.
Unicast address: 172.30.18.50
Multicast address: 239.130.18.50:4002My question is how can I request the Unicast address, but receive the video on the multicast address ? (BTW, the ffplay operation does not work even if I replace the Unicast address with the Multicast address below)
NOTE : After looking at the Wireshark trace, I see the video data has GSMTAP in the protocol column. When I do "ffmpeg -protocols : I see there is a Decoder "gsm" which decodes raw gsm. however, when I use ffplay -f gsm ... I get "Protocol not found".
I am able to use VLC to view the video using the following command :
VLC rtsp://172.30.18.50
It appears from the Wireshark trace that the session is initiated on the Unicast address, but the video is streamed on the Multicast address. VLC is able to determine this and perform the appropriate operation. I don’t know what to add to ffplay to let it know that another stream will be carrying the video.
I am UNABLE to perform the following ffplay commands (none of them work) :
ffplay -v debug rtsp://172.30.18.50
ffplay -v debug -rtsp_transport udp rtsp://172.30.18.50
ffplay -v debug -rtsp_transport udp_multicast rtsp://172.30.18.50NOTE : I am able to get ffplay to launch, but the video is garbled badly. Maybe this bit of information will ring a bell for someone ? The command I used was :
ffplay -v debug -i udp://239.130.18.50:4002?sources=172.30.18.50
The version of ffplay I’m using is :
