hello i want to change bytes per line. but i didn’t find where. how can i change ? because if i capture image i see left side green image. i don’t want see green image. so i think bytes per line is (1920 x 2). but my camera image size is 1824 so i want to change that.

Modify the TEGRA_STRIDE_ALIGMENT to 1 in …/kernel/kernel-4.4/drivers/media/platform/camera/vi/core.h
Then the Bytes per Line should be change to 1824*2

Thank you for your reply :)
…/kernel/kernel-4.4/drivers/media/platform/camera/vi/core.h → TEGRA_STRIDE_ALIGMENT is already 1.
but i can not change bytesperline = 1824*2

After you change the aligment to 1 the bytesperline should be the width*2
