Hi Ted, 

That's note was for ltib version where you have to copy the libOpenCL On yocto Stop copying. However it should work on Yocto, but I have not tested.

Hi Bio,

Thanks for your suggestion.In fact I have a 120FPS camera using MJPG. I tried to use OpenCV to capture images.But OpenCV seems to be the conversion of MJPG to RGB by CPU. The frame rate of this method is only about 5FPS.

And I noticed that IPU can be used for conversion. but I find it seems convert yuv to RGB? How can I convert MJPG to RGB?
