Hi, I am not sure if this is the right mailinglist (since I have an ogg problem not a vorbis)..... I am looking for some pointers on how to packetize an ogg stream. My idea is to use udp packets for transport, so I would need a way that would minimalize the impact of lost packets. Are there any code examples out there for this? Thanks, Jeroen p.s.

The unresolved issue is how to send the three header packets (including the codebooks) which must be made available immediately to new connects and transmitted losslessly. There's also been some discussion regarding the codebook header being prohibitively large in applications with many short segments (like commercial radio advertising) or contrariwise, how to change metadata independently of the codebooks, if that issue is handled by compression as a continuous stream.> Are there any code examples out there for this?Not that I'm aware of. Two programs that would be good places to start are icecast2 (which does http vorbis streaming) and Apple's Darwin Streaming Server (which does quicktime over rtp). -r p.s. vorbis-dev is the more appropriate list for this question. I've cc'd. --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-dev-request@xiph.org' containing only the word 'unsubscribe' in the body.

I no longer remember for sure, but I believe it was posted to the dev lista few months back... I suspect a Google search will turn that document up quickly.
