Dear all:

I use mx6s_v4l2_capture.out to test ov5640 camera preview,it's worked,but the cpu share is nearly 100%. I think color conversion comsume too much CPU. I notice imx6ul has PXP module can convert color space, how can i use pxp convert camera data and display it on lcd?

Thanks.

Hi leo

one can look at pxp unit tests pxp_lib_test, pxp_v4l2_test

test - imx-test - i.MX Driver Test Application Software

Hi，I'd like to do camera preview with

'gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw,format=YUY2,width=640,height=320 ! imxvideoconvert_pxp ! video/x-raw,format=RGB16 ! waylandsink'

but I can not find this command in my rootfs, how can I get this command with yocto? Thanks
