Hi,

Can you please save the image, which is going to the display and analyze offline to see if it has correct RGB data? 

Also can you please check if the image format is matching between image and the one configured in the video pipeline? This looks like some format mismatch..

Hi，

I analyzed the picture data, make sure it is normal RGB format。 Tried to brush with DRM direct memory data display is normal 。Perhaps in OpenGL rendering went wrong?
