decklink: unable to reduce bit depth from 10 to 8 bit using the video-format
There is no way to reduce the bit depth from 10 bit to 8 bit to save computing power while leaving autodetection of resolution enabled. The "video-format" flag does not work without specifying the "mode" flag at the same time. For example, an attempt to reduce a 10bit-yuv video to 8bit-yuv ends up with the message: "Video input format does not match the user-set format".
