Very verbose ...

Couple of general comments:

 - v4l2src 0.10.10!? The current version is 0.10.14. It's
   usually a good idea to try something more recent before
   filing bugs.

 - just because gst-inspect-0.10 xvimagesink shows RGB caps
   in the pad template does not mean that xvimagesink will
   actually accept/support RGB caps in your particular case.
   It may just accept YUV caps. What it supports is queried
   at runtime (after the elements are linked).

> gst-launch-0.10 v4l2src ! capsfilter,width=320 ! ffmpegcolorspace ! ximagesink
> display a video in 1600x1200

 - this syntax is not valid. You're lucky it's parsed at all.
   feel free to file a bug against the parser so we can
   throw an error here.

> gst-launch-0.10 --gst-debug=v4l2src:3 v4l2src ! ffmpegcolorspace ! video/x-raw-rgb,width=320,height=240,framerate=5 ! xvimagesink
> WARNING: erroneous pipeline: could not link ffmpegcsp0 to xvimagesink0

 - specified like this, framerate will end up being of (int) type,
   which is incompatible with the (fraction) type in the xvimagesink
   pad template caps. Try framerate=5/1

Hope this helps.
