Ogg Theora Streaming Discussion

[savage747]

- libtheora alpha4 has been released (API updates, encoder bugfixes and crasher bugfixes IIRC)

- fluendo.com has released the first version of Cortado, a theora player implemented as java applet (intended for usage with their Flumotion streaming server) http://www.flumotion.net/

- the official spec is available at http://www.theora.org/doc/Theora_I_spec.pdf - I recommend pointing to this document

Icecast supports Ogg Theora streaming beginning with version 2.2.0 (released some days ago) - http://www.icecast.org/

how does the interoperability between the two streaming servers look like? (meaning do all the players, able to handle streamed ogg theora, handle it, no matter what streaming server was used?) is http streaming used in both cases?

sorry but i am not really the streaming guru ;)

All servers streaming Theora use HTTP at the time being. Every Theora compatible client with HTTP streaming support will work with any server.

(btw: VLC - http://videolan.org - supports Theora streaming, too)

There are efforts to specify Vorbis/Theora usage over RTP (very usable for multicasting to save bandwidth). http://lists.xiph.org/pipermail/xiph-rtp/

This is, however, still in discussion.

thanks a lot :)

PeerCast has supported Theora/Vorbis streaming in OGG for some time
now. I've had some success using this format with PeerCast via UK
broadband connections upload capped at 125kbps.
If you install the Peercast client:

www.peercast.org

Theora/Vorbis OGG streams show up as OGM on the PeerCast yellowpages.

yp.peercast.org

I currently have a PeerCast test stream running at 95kbps at:
(Peercast's stream search format)
http://127.0.0.1:7144/stream/793CC28B0719E9C2F846C7B8CB5C4B49.ogg

I'd recommend viewing this with RealPlayer10 and the Xiph
Theora/Vorbis plugins but VLC also makes a reasonable job of it too.

The above stream was encoded using Helix Producer(win32) and the
Producer Xiph plugins for Theora and Vorbis.
