Hi,

If an ogg file contains a skeleton oggdemux used the presentation - basetime in
the fishead as the start of the segment. Unfortunately when streaming skeleton
files using icecast the presentation time in the fishead doesn't get updated.
Which leads to the situation where gstreamer starts a segment at time 0:00.00,
but the first media packets have timestamps at say 2:14.00. Causing the sink to
then wait two hours and 14 minutes before actually playing the meda :(

An easy workaround is to just ignore the start time as indicated by the fishead
and instead fallback to the starttimes of the media (like is done when an ogg
file doesn't have a skeleton).. But i'm not sure if this would break other
things, it does fix the problem that currently you can't view debconf video
streams using gstreamer based applications..
