Re: Live Stream Encoding

I have written a simple HTTP server which streams a "virtual" file. The 
file doesn't exist in real, my pictures grabbed directly from the frame 
buffer (OpenGL), encoded via Theora and sent with the windows socket 
functions to the client (Firefox 3.6.3). For response i am using this header

HTTP/1.1 206 Partial Content
Accept-Ranges: bytes
Content-Type: video/ogg
Connection: keep-alive

and attached the output from Theora directly after this header.

Additionally for debugging i can write the Theora output to a file. This 
file can be played correctly in VLC but without the correct duration. In 
Firefox it doesn't play the first two seconds.

The stream is "infinite". What do you mean with "OggIndex"?
