Hi list,

I am using gstreamer-1.5.90 on ubuntu14.04.

So here's the pipeline which intend to resize a video stream :

gst-launch-1.0 videotestsrc num-buffers=500 !
video/x-raw,format=RGBA,width=828,height=544 ! glupload ! glcolorscale !
capssetter caps="video/x-raw,format=RGBA,width=800,height=600" ! gldownload
! glimagesink

The problem is with *glcolorscale* along with the *capssetter* : If I put
*width* and *height* other then the original ones (828 X 544 ) I get black

PS :

   - The API which my gstreamer uses is OpenGL
   - When preserving the same resolution I get the normal video stream.

Best Regards,
