  I am working on imx6q with android7.1 platform ,I want to setting the Max9286Mipi.cpp ,pass the parameters to IPU.

We want change the camera module image from YUV422(UYVY) to NV21,when I did not change the parameters,the camera app preview is normal,but capture the video,the video file is abnormal.(attachment: VID_19700101_000326.yuv)

when I change the  

sensorFormats[index] = v4l2_fourcc('Y', 'U', 'Y', 'V');---->sensorFormats[index] = v4l2_fourcc('N', 'V', '1', '2'); 

 availFormats[index++] = v4l2_fourcc('Y', 'U', 'Y', 'V');


the system camera can not open.

is any wrong for my change?
