ogg demuxer
-----------
This ogg demuxer has two modes of operation, which both share a significant
amount of code. The first mode is the streaming mode which is automatically
selected when the demuxer is connected to a non-getrange based element. When
connected to a getrange based element the ogg demuxer can do full seeking
with great efficiency.
1) the streaming mode.
In this mode, the ogg demuxer receives buffers in the _chain() function which
are then simply submited to the ogg sync layer. Pages are then processed when the
sync layer detects them, pads are created for new chains and packets are sent to
the peer elements of the pads.
In this mode, no seeking is possible. This is the typical case when the stream is
read from a network source.
In this mode, no setup is done at startup, the pages are just read and decoded.
A new logical chain is detected when one of the pages has the BOS flag set. At this
point the existing pads are removed and new pads are created for all the logical
streams in this new chain.
2) the random access mode.
In this mode, the ogg file is first scanned to detect the position and length of
all chains. This scanning is performed using a recursive binary search algorithm
that is explained below.
find_chains(start, end)
{
ret1 = read_next_pages (start);
ret2 = read_prev_page (end);
if (WAS_HEADER (ret1)) {

ogg and the granulepos
----------------------
an ogg streams contains pages with a serial number and a granule pos. The granulepos
is a number that is codec specific and denotes the 'position' of the last packet
in that page.
is a number that is codec specific and denotes the 'position' of the last sample in
the last packet in that page.
ogg has therefore no notion about time, it only knows about bytes and granule positions.
