Hello, I am not a V4L developer so if this is not the right place to bring up the issue please tell me who to contact instead. The page [1] documents a problem with a particular device "Elgato Cam Link 4K" which provides various format options among which most software does not consciously pick the one which it implicitly expects leading to problems. There is a software workaround, transcoding and looping through a virtual device and a hardware fix flashing the problematic profiles away. However it appears to me that the most satisfactory solution is hinted at in the sentence > I couldn't find any option in V4L to force selection of 'YUYV 4:2:2', so instead So my question is: what changes would be necessary to allow v4l2-ctl to enforce a particular format and who would be the right person to ask to make such changes?
