*
* video frame scaling and colorspace conversion.
*
* ## Scaling and Color space conversion
*
* Equivalent to glupload ! gldownload.
* glcolorscale implements scaling of GL video frames, equivalent to
* #videoscale. The initial implementation also performed colorspace
* conversion, hence the name of the element, but support has since
* been removed. You should use #glcolorconvert for that purpose.
*
* ## Examples
* |[
* gst-launch-1.0 -v videotestsrc ! video/x-raw ! glcolorscale ! ximagesink
* ]| A pipeline to test colorspace conversion.
* FBO is required.
|[
* gst-launch-1.0 -v videotestsrc ! video/x-raw, width=640, height=480, format=AYUV ! glcolorscale ! \
* video/x-raw, width=320, height=240, format=YV12 ! videoconvert ! autovideosink
* ]| A pipeline to test hardware scaling and colorspace conversion.
*
* ``` shell
* gst-launch-1.0 videotestsrc ! video/x-raw, width=640, height=480 ! glupload ! \
* glcolorscale ! glcolorconvert ! gldownload ! video/x-raw, width=320, height=240 ! \
* autovideosink
* ```
*
* A pipeline to test hardware scaling and colorspace conversion.
* FBO and GLSL are required.
