Video input 1600*1200 resolution support issues on NVIDIA AGX Xavier

Hi,
When the video input resolution is 1600 x 1200, nvV4L2CamerasRC is used to play the splintered screen, and V4L2SRC plays normally. Nvv4l2camerasrc can play normally with other resolutions. What is the reason for this?

Best Regards!
