Vorbis - Sep 2004 - Streaming from memory

How would one go about streaming an entire ogg file from memory?  That is,
I'd like to read the entire file right away and then just decode as I go.

I'm currently using the various functions in vorbisfile.c which read from
files but it's causing intermittent stuttering in my game since the calls to
ov_read sometimes experience spikes in return time.  I'm guessing that these
spikes are due to issues with reading from the disk so I'd like to just keep
the ogg files in memory.

Thanks,

Hi Ken,

i had the same problem. But there's a solution: you can supply 
VorbisFile with your own callback functions for reading and seeking:

it's actually pretty simple.
