Original commit message from CVS:
* sys/v4l2/v4l2src_calls.c: (gst_v4l2src_probe_caps_for_format):
If VIDIOC_ENUM_FRAMESIZES is defined (= recent kernel), but the
corresponding ioctl() call fails even though the driver claims to
support this format, just fall back to the pre-2.6.19 kernel
routine that creates caps with suitable height and width ranges
(see #448278).
