It's a merge bug. Sorry. I have pushed an update that fixes this so you 
may want to rebase.

The initial push had caps issues, mostly it was missing format=BGRx, 
which caused GStreamer 1.0 not to work. Note that the failure mode 
caused the video to be sent through the regular non-stream channel so it 
looked like it worked.

Now the GStreamer 1.0 situation is as follows:
 * VP8 works.
 * MJPEG fails because of a caps negotiation error despite the 
   videoconvert element.
 * H264 seems to work but the client fails to display it. So I'm not 
   totally sure.

Also I finally found the right parameters to improve the VP8 encoder 
performance.

Cheers,
