imx6sololite not support usb Camera YUV422 output

I am now developing a monitoring equipment, because the camera and the imx6sololite is far from the distance, about 20cm, can only use usb camera , can not use the CSI interface

Camera. But the  IMX6SoloLite video interface only supports YUV 420 encoding into h264, and  usb camera can only output YUV422 format。 so I need to use the software to turn,the  YUV422 to  YUV420, but this is seriously  Occupy CPU resources, even though the resolution of 680*480 can reach 80% CPU occupancy rate. 720P is even higher, so the Software conversion format Could not be used

Please comment there is no good way to solve this problem?

Hi tao

i.MX6SoloLite has not VPU, VPU uses YUV420 for encoding into h264.

In general, link below shows examples with CSC for conversion YUV422 to  YUV420

Hi igor

thank you。

I am wrong, i used i.MX6Solo  not i.MX6SoloLite。

I used to try to use IPU to convert the format, but it looks like the IPU interface is CSI not USB
