glcolorscale

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 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.
