When starting, the transcode's import_v4l2 module by default report a line like this: [import_v4l2.so] v4l2 video grabbing, driver = saa7134, card = Pinnacle PCTV 310i So you can verify what is connected to the device node. Unfortunately, this is printed out at the end of the setup, so we must fix the colorspace issue before (or use a different tool).
