Dear Otavio,
thanks for your suggestion.
Do you mean this module: meta-freescale/recipes-graphics/imx-gpu-viv ? The version is 5.0.11.p8.6.
How can I find out the version of module inside the kernel source and binary driver?
Based on further experiments I have more details about the behaviour:
When I start any Qt application with GUI and then I try to run
export DISPLAY=:0.0 && gst-launch-1.0 videotestsrc ! imxg2dvideotransform ! imxeglvivsink,
I see only a black screen inside the window.
But when I restart X server and run the same Gstreamer pipeline again (without running GUI application before), the I can see the videotest output successfully.
Can this description help you to find any recommendations?
Best,
Vaclav

This is mostly likely to be due the different between the GPU driver
module inside the kernel source versus the binary drivers.
Check if you are using our external module and it should work.
