Live streams vs Files?

[Stirling Westrup]

I'm having some problems with my gstreamer application. I've added a
switch to allow someone to specify a live stream (from ximagesrc in my
test case) rather than a video file as a source.

Playing a video file works, but attempts to play the video from
ximagesrc fails with a blank screen.  As far as I can tell the problem
is that my xvimagesink is waiting for pre-roll, which its never going
to get. However, if I build simple model of the pipeline with
gst-launch, it works.

So, basically, I think there is probably something fundamental about
how you set up a pipeline for a live stream that must be different
from a canned stream, but my searching of the gstreamer documentation
hasn't given me any clues as to what.

So, does anyone have any clues for me as to how manipulating a dynamic
live pipeline differs from a dynamic canned one?
