i.MX6Q 1080P encode problem

Hi Community,

I'm new to VPU encoding. We encouter a problem and have no opinion about it. :smileyconfused:

MIPI camera input source is 1080P 30fps or 60fps, the preview image is normal. however, after encoded, the image seems abnormal. Viewed from image displayed, it seems that RED and GREEN are changed each other. please see below picture for comparing.

Could you give me some advices? :smileyhappy:

Many many thxs....

You need to verify the VPU supported YUV formats.

You need to do YUV format conversion before encoding.

Thanks

the rootcause is that 1080P input is different from 720P input. the format of 1080P is YV12.
