Exactly, something along the lines of theora_encode_DUPin() would do the
Nudging off-topic, the libogg API pages at xiph.org seem to have gotten
mixed up or corrupted. For example parts of the page for
ogg_stream_pageout() seems to be describing ogg_stream_pagein().
What I was actually looking for was who owns the memory the ogg_page
structure points to after a call to ogg_stream_pageout()? I'd like to
keep a copy of the initial pages for saving parts of the live stream to
a local file later.
