Detailed description
OpenGL/OpenCL and VAAPI/OpenCL interop fail when used in the same program. I want the following:
- Draw on the GPU via OpenGL
- Share a buffer with OpenCV (via cl_khr_gl_sharing) and use OpenCV/OpenCL algorithms on it
- Share a buffer with VAAPI (via cl_intel_va_api_media_sharing) and encode to video on the GPU
The very first error I hit was:

Steps to reproduce
I wrote a full example you can read on github: https://github.com/kallaballa/GCV/blob/main/src/tetra/tetra-demo.cpp
and a OpenCV 4.x fork (branch GCV) with the changes I needed to get it to work: https://github.com/kallaballa/opencv/tree/GCV
For Linux/Intel user this issue might be of interest to get this to work: intel/compute-runtime#166
Issue submission checklist
- I report the issue, it's not a question
- I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
- I updated to the latest OpenCV version and the issue is still there
- There is reproducer code and related data files (videos, images, onnx, etc)
