Jared McNeill very kindly pointed out I wasn't using VIDIOC_QBUF at all, which of course explains it. I'm fairly sure I wrote a loop with those in it. I don't know whether I'm hallucinating, or I managed to completely lose it during edits at some point, or what, but I find that (a) he's right, of course, and (b) when I supply them, it works just fine. My thanks to him for the thawck with the cluestick and my apologies to everyone for being such a friggin' idiot and bothering the list with a stupid mistake that could have been corrected with a careful reading of the manpage and the code. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mo...@rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
