I assume you're using libvorbisfile.
Instead of calling ov_open() (which takes a FILE *, to read from a file), use 
ov_open_callbacks, providing a set of callbacks which read data from your 
pre-allocated buffer. These callbacks are fairly trivial to write (and even 
simpler if you don't want to support seeking).
