debug log when using gstcolorspace

gst-launch --gst-debug=GST_PADS:5 v4lsrc device=/dev/video0 ! colorspace !
ximagesink > gstcolorspace.log 2>&1
Comment 2 Stephane Loeuillet 2004-04-08 23:41:07 UTC 
as a sidenote : i first used spider in the middle, instead of (gst)colorspace
but it seems spider has a preference for (gst)colorspace

perhaps ffmpegcolorspace should have a higher rank
Comment 3 David Schleef 2004-04-09 00:04:55 UTC 
Ok, fixed.  I think.  Now it should fail to negotiate.  I also bumped the rank
of ffmpegcolorspace to PRIMARY, which beats colorspace.
