sys/v4l2/v4l2src_calls.c: but the corresponding ioctl() call fails even though the driver claims to support this form...
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).
