The following takes a little more than 40s (sic) before it shows anything :
gst-launch-0.10 v4lsrc ! xvimagesink

It's slow because it's trying to do some probing, so :
v4lsrc autoprobe=0 ! xvimagesink
but of course that won't work : how to use correctly a device which never was
probed !? The error is :
ERROR: from element /pipeline0/v4lsrc0: Could not get/set settings from/on
resource.
Additional debug info:
v4lsrc_calls.c(264): gst_v4lsrc_grab_frame (): /pipeline0/v4lsrc0:
Device is not in streaming mode

Let's try with autoprobe-fps :
gst-launch-0.10 v4lsrc autoprobe-fps=0 ! xvimagesink
same problem :
ERROR: from element /pipeline0/v4lsrc0: Could not get/set settings from/on
resource.
Additional debug info:
v4lsrc_calls.c(264): gst_v4lsrc_grab_frame (): /pipeline0/v4lsrc0:
Device is not in streaming mode

All in all, that means this source gives issues when used in a program : which
user will accept to choose a device and see the application freeze for that
long?!
