Comment (by dcbw):

 VIDIOC_ENUM_FRAMESIZES is the _new_ way to figure out what frame sizes the
 camera supports.  The old way is redundant.  ENUM_FRAMESIZES is Good
 Thing, because the old way was to toss successive values at the driver and
 when it returned -EINVAL you'd gone too far (ick).  However, it's not
 integrated into the kernel V4L framework well enough and only a few
 drivers implement it.

 That said, I don't think this is the problem that gstreamer 0.10.13 is
 showing, because in my testing in July, gstreamer wouldn't even show any
 video at all, having failed the image size queries because our driver
 doesn't support the new way.

 I think this is a different issue entirely.

 And the problem with "cafe1000-ccic 0000:00:0c.2: Frame overrun on [012],
 frames lost." has _always_ been there and is a kernel driver problem,
 since it shows up from VTs.
