People with supporting hardware may try this out and report, maybe someone can port a test FFmpeg filter with a matrix to OpenCL and report offloading
performancecompared to x86 filter code running on CPU (S)SSE2/3/VXA.

grep didn't find any opencl in debian testing X, vaapi, source packages besides of mesa which I don't in which dev package opencl code should be, nor "gallium":
