Hey Stefan,
I have a question slightly related to this. Most of the webcams I have
and I've seen so far seem to output a couple somewhat broken frames as
they start streaming. Is there a simple way (e.g. something you can do
with a gst-launch line) in gstreamer to drop the first n frames? I
mean to actually retrieve them from the v4l device but drop them as
videorate does.

Ciao,
Filippo
