Out of curiousity, can cedrus_formats[i].capabilities > be zero? Because it feels like that's what should be checked. Yes, it can be. It's the case for V4L2_PIX_FMT_NV12_32L32. All variants supports it, so there is no special capability needed in order to be listed. What would you check in such case? Condition still works for this case. Best regards, Jernej
