On va configurer rapidement le serveur IceCast2.

Envoie d'un flux vidéo VLC sur Icecast
Exemple d'une requête VLC pour créer un /point de montage Icecast sur un serveur distant :
flows.zw3b.fr:8000/cam0→ le rendu de la caméra. - non disponible actuellement
La requête ci-dessous récupère le périphérique /dev/video0 de l'ordinateur.
Et envoie le flux vidéo sur une autre machine (au Canada en l'occurrence, sur un container de ma serveur hébergé chez OVH) la machine "10.101.150.80 sur le port "8000" qui bien sûr passe par un VPN.

Cela permet de créer un flux constant en (vrai) streaming. Ce n'est pas un WebCam avec des images toutes les minutes.
Liquid SOAP (de Savonet)
#Liquidsoap est un outil puissant pour créer des générateurs de flux audio et vidéo complexes, ciblant généralement les radios Internet #webradio et les #webtv. Il se compose d'un langage de script simple, qui a une notion de première classe de source (essentiellement un flux) et fournit des constructeurs de source élémentaires et des compositions de source à partir desquels vous pouvez créer le générateur de flux que vous souhaitez. Cette conception rend le savon liquide flexible et facilement extensible.
Je vous pose un exemple de scripting liq liquidsoap 1.1.1 (la version LiquidSoap 2.2.0 est disponible mais ce script ne fonctionne pas avec, il faut l'adapter).

Il faut faire attention, l'ordre dans le fichiers est "extrêmement" important.
Pour lancer le streaming encoder en 2 formats (%vorbis et %mp3 et d'autres -- il faut installer les codecs des "dépots multimedia de débian" par exemple pour le codec "flac" etc.).

J'écris la suite prochainement..
Histoire que vous essayez, ce n'est pas forcement simple.
Je vous laisse lire la documentation Liquidsoap.
Je vous expliquerais et détaillerais les fonctions et ajouterais la mise en place de possible connection de "DJs" sur le flux "constant" de la Web Radio.
J'ai fais des test de streaming vidéo avec inscrutation "image dans image", logo, ticker, text etc.. cela doit mieux fonctionner avec la version 2.2.0 qu'avec la version 1.1.1.
je vous laisse découvrir !
Romain, bonne soirée.

Il y a 5 utilisateurs DJ qui peuvent interagir sur la webradio à n'importe quel moment - En gros, le bordel. On peut définir des plages horaires.
Pour vous connectez il suffit de lancer une "table de mixage" type le logiciel Mixxx : Diffuser en live de la musique disponible sur Microsoft, Linux et Apple.
Bon mix !
