Hello
It uses autovideosrc which should pick the default video source from
your system. You can hack the code to pass a hardcoded videotestsrc
easily. Bonus points if you provide a patch that adds a command line
parameter for selecting the video source to use, defaulting to
autovideosrc.
For investigating what's the cause of the hang, I'd need more details
and gstreamer logs (GST_DEBUG logs).
