Re: [osg-users] Rendering 2 video stream
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi Adrian, You can stream directly from the source, but in order to avoid the same machine support the broadcasting and generating the stream, i used two machine: o the stream generator o a server on the net that can send 100Mb/sec If you have only a few client or if your stream needs to be view in localnetwork then maybe you can avoid the broadcast server. To use the flux on a webpage i used http://www.flumotion.net/ . You can have a look on the web, then the html needed to use the flux is video width=600 height=400 autoplay=yes src=http://stream.pok.me/stream.ogg view-source:http://stream.pok.me/stream.ogg tabindex=0 /video Off course you will maybe need some fallback depending on your target.

Well once i have the video rendered , i launch gstreamer with gst-launch-0.10 and with the parameters you send me once. Now the gstream takes the input from location and streams it as a ogg video over network. Do i need a webserver instance to stream to or how does it work? own can i integrate it into a firefox html webpage. say i will stream it from localhost and watch on localhost with firefox -console my_Test_page.hmtl with the video display. and i have the osgviewer application running and i can navigate with my mouse (as common) and watch in real time the video beside with a copy of the osgviewer frame buffer output/ /adrian Hi, I render a video game based on osg into a video stream, you can have an idea here http://plopbyte.net/?page_id=6/ you need a firefox plugin to watch it.
