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

Mark Thompson	7faa8d8b03	lavfi: Add OpenCL unsharp mask filter Intended to replace existing opencl mode of the unsharp filter. Supports many more pixel formats and works without immediate upload and download of frame data. The options are compatible with the existing filter.	2017-11-22 23:18:35 +00:00

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.
