Jan Schmidt 38baf136e6 sys/v4l2/v4l2_calls.c: Treat ENOTTY (driver does not implement ioctl) the same as
Original commit message from CVS:
* sys/v4l2/v4l2_calls.c: (gst_v4l2_fill_lists):
Treat ENOTTY (driver does not implement ioctl) the same as
EINVAL since it implies there are no available standards.
* sys/v4l2/v4l2src_calls.c: (gst_v4l2src_probe_caps_for_format),
(gst_v4l2src_get_nearest_size):
Replace gst_v4l2src_get_size_limits with 2 calls to new function
gst_v4l2src_get_nearest_size, and get it to use VIDIOC_S_FMT to
probe if the driver does not support VIDIOC_TRY_FMT for whatever
reason, and if we aren't yet actively capturing.
* sys/v4l2/v4l2src_calls.h:
Remove replaced function declaration.
