What would you do? make the window unresizeable? That's hardly very usable. Anyway to get this information about what fixed sizes a card supports, other than some kind of guessing game? X window managers don't support the general concept of a few fixed sizes for a window anyway, so it wouldn't be that useful. > > Any chance of getting aspect ratio information, so that window > > resizes can be contrained that way too? > > Anything missing in v4l2_cropcap? Is there any information on v4l2_cropcap? The v4l2 document on thedirks.org just says: Still to come.... I see a "pixelaspect" in the v4l2 header file, but the name alone doesn't make it clear how it's used.
