Sorry, I don't make myself clear here. I wanted to try v4l on my Ubuntu development system first - it's this that isn't working:

gst-launch-0.10 videotestsrc ! v4l2sink
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstV4l2Sink:v4l2sink0: Cannot identify device "/dev/video1".
Additional debug info:
v4l2_calls.c(493): gst_v4l2_open (): /GstPipeline:pipeline0/GstV4l2Sink:v4l2sink0:
system error: No such file or directory
Setting pipeline to NULL ...
Freeing pipeline ...
