Oops, wanted to add that if you are validating things on Android, CTS contains tests that utilize Media + GL stack and validate the media use-case.

[Mesa-dev] Zero-Copy Texture usage from OpenCL
Hi, Can someone please help to validate below MESA features. "system shall allow 3D rendering to make use of OpenCL buffers in a zero-copy manner" "system shall allow 3D rendering to make use of Media SDK buffers in a zero-copy manner."
