v4l2src: Add GstURIHandler interface.

This allows using v4l2://[<device>]

Review of attachment 147207 [details] [review]:

Looks good in general, could you do the same for v4l(1) too? :)

+  return g_strdup_printf ("v4l2://%s", v4l2src->v4l2object->videodev);
+}
+

Isn't it possible that ->videodev is NULL?

What is the use-case? I was thinking of adding this to videotestsrc, as one could then test playbin2 without media :)

I was writing some minimalistic application which encodes a given uri. With this you can just do : tests/encode val2:// -format ogg

See gst-convenience/tests/examples/ for the code.

But yes, you could also do playbin2 uri=v4l2:// to just view the camera

I don't want to steal the bug, but I wonder if then we should have some extra parameters in the uri, like "num-buffers". The video-mode can be selected with a capsfilter already.

Adding parameters might be interesting, but to me sounds like a separate bug report. I think Edward should commit this, with slomo's comment applied :)
