Comment 15 for bug 930372

This patch is from freescale internal. for the videosink support csc and resize, it will not connect videoconvert and videorescale.
It will help i.mx for performance with freescale's gstreamer plugins package..
We discussed it in the LC Q1 2012 that freescale landing team do not want release the gstreamer-plugin-base package dedicate for freescale . And the patch should be harmless for the TI platform.
I have test it on the panda board, and does not see any bad affect until now.
