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 (...) -

Trying to stream H264 with Janus Gateway to web browser
15 mars 2021, par sibrownI have installed Janus-Gateway using the very comprehensive install instructions on an Ubuntu 18.04LTS machine.
I have configured the streaming config file (janus.plugin.streaming.jcfg) with :



gstreamer-sample: {
 type = "rtp"
 id = 1
 description = "H.264 live stream coming from gstreamer"
 audio = false
 video = true
 videoport = 5004
 videopt = 96
 videortpmap = "H264/90000"
 videofmtp = "profile-level-id=42e01f;packetization-mode=1"
}




(I didn't change the name because that required least changes to other files.)



Having then started the server, I then take a pre-encoded stream and send that to the server with ffmpeg :



ffmpeg -i udp://127.0.0.1:9034 -c:v copy -an -f rtp rtp://127.0.0.1:5004?pkt_size=1300




Opening up the demo webpage the server comes with, I go to streaming demos, and choose the "gstreamer" demo and click start. The right hand half of the screen produces a spinning circle, but tells me that it is receiving data at the appropriate rate for the stream I'm sending. So if it's receiving the stream, why isn't it playing it ?



Cheers,
Simon
