[gst-devel] colorspace plugin (inside a c program)

Hi Jeremy,

when can we see your app ? :) it sounds interesting.

Yes, since fakesink accepts anything, colorspace will not be motivated
to change something :) Check gst_element_link_filtered; that way you can
specify what caps to use on the link between colorspace and fakesink. 
Forcing a specific format that way will cause colorspace to do a
conversion.

Bear in mind that
a) colorspace in HEAD might be buggy, I have run into issues this
weekend
b) I have no clue what format to specify, but they should be basic caps.
