[Icecast] [Video at Xiph] OGG Theora streaming

[WCI Peter Lewis]

Hi,

We are building our own custom streamer using your theora libraries. If we 
can get help to debug the solution and figure out why its not streaming 
smoothly that would be great. The end gold is to have a custom streamer for 
Windows and Mac that streams to icecast and can be viewed using HTML5. If 
you have any questions or need further details I would be happy to provide 
more details and thank you for the quick response .

Regards
Peter Lewis

Visionair isn't ours (xiph's) directly. but it does use our libraries
somewhere to do the actual encoding stuff.  Layers upon layers :-)  I
know about it and have seen it used, but never worked directly with it
myself.  I'm not sure what others on the list have-- there's a good
chance (it looks nice).  You may need to contact the Visionair folks
for setup help.

That said, we do know Icecast and the actual Ogg streaming formats
very well.  We can help debug from that side.

(BTW, Ogg isn't an acronym, it's just "Ogg")

I don't know Visionair setup, but Icecast itself doesn't do much
buffering; it's just a 1->many server that passes whatever the source
hands it onto whatever client connects.  The exception is when
'burst-on-connect' is enabled, in which case it keeps around a small
buffer so that when a client connects, it can fill the client-side
buffer rapidly.  There's also a little bit of in-band fanciness to
start an Ogg stream properly in the middle.

Are you doing broadcast streaming, or low-latency conferencing, or...?

(BTW, I've trimmed the response list down to just icecast at xiph.org
since that's the most appropriate place for it to go).
