Description Julien Isorce 2014-05-29 10:13:23 UTC 
1- should support GstBaseTransformClass->passthrough_on_same_caps

Indeed if the caps are exactly the same, there is nothing to do (i.e. no need upload->download)

2- Currently "videotestsrc ! glcolorscale ! "GL" ! fakesink" uses 2 FBO, one
for the upload and one that just does the identity. The later should be
avoided.

This should be fixed by

https://bugzilla.gnome.org/show_bug.cgi?id=732178

and 

commit 720405b56188773a68ac521b491c21a4eac61f05

    glfilter: pass through the allocation query when in passthrough mode
    
    Otherwise two GL elements on either side will fail to use the same
    GL context.
