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.
