           Summary: Higher frame rates cause glimagesink to use excessive
                    cpu
    Classification: Desktop
           Product: GStreamer
           Version: 0.10.1
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-gl

I'm not sure if this is something that can be fixed, but I noticed glimagesink
using more cpu than I thought it should with my HD videos. I think it is
related to the frame rate see the test launches below:

gst-launch-0.10 videotestsrc !  "video/x-raw-yuv, format=(fourcc)I420,
width=1280, height=720, framerate=(fraction)80/1" ! fakesink sync=1

gst-launch-0.10 videotestsrc !  "video/x-raw-yuv, format=(fourcc)I420,
width=1280, height=720, framerate=(fraction)80/1" ! glimagesink

gst-launch-0.10 gltestsrc ! "video/x-raw-gl, width=1280, height=720,
framerate=(fraction)80/1" ! glimagesink

I know "top" is very relative, but these are my quick and dirty findings with
my linux box:

fakesink uses: 15% CPU
glimagesink uses: 25% CPU

for reference:
gltestsrc uses: 2% CPU
