Hi,

Nice! I am intereted to test it but I did not see it in cvs
gst-plugins-bad/sys. Maybe cvs will be updated later.

By the way, I have a question about vscc.OutputGranularityX
vscc.OutputGranularityY. It seems that you did not used it. I am ok, it is not
very important, because it could be strange to use : ... ! video/x-raw-rgb,
width =720, height= 575 ! ....    575 instead of 576, but It could happen.
I used it in the dshowvideosrc element
http://bugzilla.gnome.org/show_bug.cgi?id=517203 (not validated yet, but I am
waitting for admins reactions)
and I really think that a new GST_TYPE is needed:  GST_TYPE_INT_RANGE_STEP.
Instead of using GST_TYPE_INT_RANGE for the gstcaps width and height.
And here step is the granularity. 
What do you think about it?

More important, in the gst_ks_video_src_fixate you set the video size and
framerate as a constant, 352, 288, 15/1.
I do not know if Windows Kernel streaming API can give the default video size
and framerate but with directshow it is possible. And I experiment it in 
http://bugzilla.gnome.org/show_bug.cgi?id=517203  .c attached file.
Because if 352 and 288 are not supported by a device, the following command
line will failed :
gst-launch ksvideosrc ! ffmepgcolorspace ! directdrawsink

I 'll test your element as soon as I see it in cvs.

Julien
