Hi Rostislav, It is just a coincidence that I am also working on the OpenCL version scale filter. So I am very interested in further discussion. I just attached my patch. It still has some problem with aspect ratio, and I only add bilinear filter, but with NV12 support. Basically it is something like scale_cuda. Based on your comments. Seems I also mis-designed the filter:( So could you talk a little bit more about your idea? Why per-algorithm scaling function seems not so good? For the mpv, do you mean something like pass_sample_bicubic_fast() @ $mpv/video/out/gpu/video_shaders.c? I have not read mpv code before, please forgive me if I am wrong. I am not sure if anybody else has idea on how we should implement the OpenCL version scaler? Thanks! Ruiling
