This is just a wild guess, but have you tried adding a videorate? From
experience I learned that videomixer doesn't work well with some
framerate combinations.

Also, I'm just curious if you can't use xvimagesink instead of
ximagesink. That would probably save you from that colorspace before
ximagesink.
