i am using a logitech camera, and i get really bad fps with this pipeline:

gst-launch-0.8 v4lsrc ! ffmpegcolorspace ! ximagesink
RUNNING pipeline ...
WARNING: Your X-Server has no DGA support.
/dev/video0 [v4l]: no overlay support
 
** (process:14628): WARNING **: v4l-conf returned 1.
ERROR: from element /pipeline0/v4lsrc0: Could not get/set settings from/on resource.
Additional debug info:
gstv4lsrc.c(636): gst_v4lsrc_src_link: /pipeline0/v4lsrc0:
Could not set framerate of 0 fps

But after i resize the window the fps goes back to normal.  

I also noticed that initially the cpu load is very low.  But after resizing the
window the cpu load is higher but the video has much higher fps.
