Mark Thompson	2a1542d105	lavfi/opencl: Derive global work size from plane image sizes ... Add a new function to find the global work size given the output image and the required block alignment, then use it in the overlay, program and unsharp filters. Fixes the overlay and unsharp filters applying the kernel to locations outside the frame when subsampled planes are present.	2018-03-22 23:12:47 +00:00
