Original commit message from CVS:
* ext/esd/esdsink.c: (gst_esdsink_get_time), (gst_esdsink_chain):
Basic hacks to make video playback using esdsink not totally make
yuou rip your heart out. We write a few samples per cycle, so that
the clock will increment in a slightly lineair fashion instead of
in large hiccuped steps (which makes video playback in an ok'ish
way, compared to how it was), and we take timestamps into account for
calculating the clock position, so that _get_time() at least returns
a value that will make video playback in sync. Should make Ubuntu
users happy (they default to esdsink).
