v4l2-compliance fails with this message: fail: v4l2-test-formats.cpp(463): !pfmt.sizeimage fail: v4l2-test-formats.cpp(736): \ Video Capture Multiplanar is valid, \ but TRY_FMT failed to return a format test VIDIOC_TRY_FMT: FAIL This failure is causd by the driver failing to handle out range 'bytesperline' values from user space applications. VPDMA hardware is limited to 64k line stride (16 bytes aligned, so 65520 bytes). So make sure the provided or calculated 'bytesperline' is smaller than the maximum value.
