Hi Wei,
I will double check using yuv.
What opencl platform/device you are running it on?
Also, can you point me to /testfile/blueangles.m4v so I can reproduce correct and not correct outputs?

Nope, this is the whole patch. git sendmail automatically added 1/2, even though this is the only part.

did you check the result? of YUV, my command is 
ffmpeg -i ./testfile/blueangels.m4v -vf unsharp=lx=11:ly=9:cx=5:cy=7:ca=1:la=1:opencl=1  -vframes 1 -y ./testfile/out.yuv

and the result of the new patches is not correct. please reference the attachment, the wrong one is created by the new patches, the correct one is node 202947a0665ea523022afb0a6c50eed96bcd6b69

BTW, I use the 2 patches you submitted before. The size of yuv is 1920x1080.
