Thanks for helping with the review. So far, we have conducted tests on 
QCS8300, SA8775P, X1E80100, and QCS8550. However, I don’t have access to 
an SM8650 device—could you help test it?

A 720p NV12 file is available here, which can be converted to 1080p 
using ffmpeg.

file: 
https://github.com/quic/v4l-video-test-app/blob/master/data/resource/simple_nv12_720p_90frms.yuv

cmd: ffmpeg -f rawvideo -pix_fmt nv12 -s 1280x720 \
-i simple_nv12_720p_90frms.yuv \
-vf "scale=1920:1080" -pix_fmt nv12 input_nv12_1080p.yuv
