A more simple trigger (if you have a camera):

gst-launch-0.10 videotestsrc ! videomixer name=mix ! ffmpegcolorspace !
xvimagesink hdv1394src ! decodebin ! ffmpegcolorspace ! mix.

Framerate is one every few seconds for both sources. One processor is
thoroughly saturated, others are idle.

Launching each stream with separate instances presents two windows operating
acceptably with ample processor headroom.

Mixing two test or pre-recorded sources performs acceptably.


version: 0.10.21

gnome version: 2.24.1
