Hello all!
I am wondering if anyone can help me locate some information concerning
streaming Vorbis files. I am needing to locate the information for a
multimedia networking class I am taking so I can learn all this audio
and networking mumbo-jumbo.
For the class, I need to locate 3 streaming media types and answer the
following questions:
Does it use Meta files?
Does it use UDP or TCP?
Is RTP and/or RTSP used?
As far as I've been able to determine thus far, by reading the
documentation (concerning Vorbis):
No
Both
No mention
Can someone help me locate some more specific information concerning any
of the above, or let me know for sure that Vorbis doesn't use said
technology?
Many thanks from a newbie!
Nick

The Ogg format is an audio format, not an audio streaming protocol. I beleive you need to look up "Icecast". which is used to stream ogg + mp3 files over the net.

There is a simplistic metadata header as part of vorbis. It just does key-value pairs. There are plans for a more comprehensive metadata format, but they're still at the design stage. Vorbis is an audio codec that produces packets. The standard implementation packs those packets into an Ogg bitstream (hence 'Ogg Vorbis'). Ogg provides framing, sync, rough seek and multiplexing capabilities and is intended for disk storage and TCP streaming. There's also a project to send vorbis packets over RTP. See http://xiph.org/ogg/vorbis/doc/draft-moffitt-vorbis-rtp-00.txt for the format and 'libvorbisrpt' in the list archives for a sample implementation currently under development. I don't know if RTSP is implemented or not. The primary intention with libvorbisrtp is multicast, so it does SDP. Shouldn't be hard to add, of course. Hope that helps, -r --- >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-request@xiph.org' containing only the word 'unsubscribe' in the body.
