[vorbis-dev] Bride of vorbisfile questions

[Rob D]

I made an mp3 player several years ago. Now it supports OGG also.

I have several puters throughout the house that can run the player over the 
network. Each of the puters are capable of controlling music on other 
computers over then network, and a few have IR remote control for next 
track, volume, etc.

My existing setup is fairly high tech, but would be nice for several puters 
to be able to play the same song at exactly the same time. I assume this is 
the main benefit of streaming.

I also assume the multichannel streaming allows all puters to select 
different songs from a single stream? I dont think I understand the usage 
of this enough to figure why.

I plan on adding stream creation and decoding to my player. It would save 
alot of bandwidth to stream the file data as opposed to the decoded PCM 
data, but I am worried that it may end up just as unsynchronized as my 
first attempt at synchronizing several decoders on the same file several 
years ago.

My first attempt was pretty goofy. I wasnt broadcasting the data, but 
rather telling each decoder when to start playing the same file in a round 
robin type fashion. There was just enough delay to be annoying if you had 
several decoders in the same room.
