Description Florent Thiéry 2015-12-11 15:50:57 UTC 
I am trying to scale video using OpenGL/GLES

No-scaling works flawlessly:

gst-launch-1.0 videotestsrc pattern=18 background-color=251651651 ! video/x-raw\,\ format\=\(string\)RGBA\,\ width\=\(int\)128\,\ height\=\(int\)72\,\ framerate\=\(fraction\)30/1 ! glimagesink

720p works good:

gst-launch-1.0 videotestsrc pattern=18 background-color=251651651 ! video/x-raw\,\ format\=\(string\)RGBA\,\ width\=\(int\)128\,\ height\=\(int\)72\,\ framerate\=\(fraction\)30/1 ! glupload ! glcolorscale ! video/x-raw\(memory:GLMemory\)\,\ format\=\(string\)RGBA\,\ width\=\(int\)1280\,\ height\=\(int\)720 ! glimagesink -v

1080p produces heavy artifacts:

gst-launch-1.0 videotestsrc pattern=18 background-color=251651651 ! video/x-raw\,\ format\=\(string\)RGBA\,\ width\=\(int\)128\,\ height\=\(int\)72\,\ framerate\=\(fraction\)30/1 ! glupload ! glcolorscale ! video/x-raw\(memory:GLMemory\)\,\ format\=\(string\)RGBA\,\ width\=\(int\)1920\,\ height\=\(int\)1080 ! glimagesink

The following video shows 1080p then 720p captured from the rpi output:

I don't see any error showing up in 1080 vs 720

The only case where I've had this is when gpu_mem is set too low to accommodate the 1080p buffers.
Comment 2 Matthew Waters (ystreet00) 2016-05-15 08:51:18 UTC 
Does this still occur with the master?
