Ogg Vorbis audio streaming

Prev:

read-vorbis-stream ( filename buffer-size -- vorbis-stream )

Vocabulary
audio.vorbis

Inputs

stream	a binary input stream
buffer-size	an integer

Outputs

vorbis-stream

a vorbis-stream

Word description
Constructs vorbis-stream over the contents of stream. When used as an audio generator, the Vorbis stream will supply data to the audio engine in buffer-size byte blocks. If the Vorbis stream is created successfully, it will take ownership of stream, disposing it when dispose is called on the vorbis-stream.
