[FFmpeg-devel] AMD Vega 56, UVD and OpenCL

[Mironov, Mikhail]

There are decoding samples and some other samples here:

https://github.com/GPUOpen-LibrariesAndSDKs/AMF

There are no samples how to get Vulkan surfaces/images into OpenCL. These are public interops that you can use yourself at this point.

Ok, I have found and installed "libamfrt64.so".  Comes with amdgpu-pro.
aptitude install amf-amdgpu-pro

So, getting closer to a possible solution.

Are their any example/sample C++ programs for Linux demonstrating how to
use the API?
I am interested in decoding H.264 on the GPU and getting the decoded frame
into opencl.

Kind Regards

James
