Summary0000215: OpenCL support via ffmpeg
DescriptionIt seems ffmpeg already have some filters utilizing openCL (even running arbitrary CL program).
See my mail https://lists.cinelerra-gg.org/pipermail/cin/2019-May/000650.html
Steps To Reproduceadd two hacks in usual places (thirdparty/Makefile and global_config)

system_libs += -lOpenCL for global_config
and
--enable-opencl for ffmpeg.cfg_params in thirdparty/Makefile

I don't have OpenCL-capable drivers for my again NVIDIA Corporation G92 [GeForce 8800 GS] (nv50-generation card), but new-ish AMD and Intel should work to some degree ....?

Do not forgot to install opencl-headers. I used icd loader coming with Mesa, but thing like ROCm and Beignet may require their own loader files.

https://github.com/RadeonOpenCompute/ROCm - overview advanced OpenCL for AMD (integrated in mesa clover state tracker limited to OpenCL 1.1 at the moment)

https://github.com/intel/beignet - Intel thing.

This sounds like it should be at least given a test; GG should be able to eventually come up with some configuration to test this now that you have done the groundwork of what has to be done to compile it in. But no time schedule yet.
