v4l2-utils: Fix incorrect use of fd in streaming_set_cap2out
Running the "Stream video from a capture video device (/dev/video1) to an
output video device (/dev/video2)" example from the manpage with vivid
as the output device failed with a error message.
vedant@pc ~$ v4l2-ctl --list-devices
vivid (platform:vivid-000):
/dev/video2
/dev/video3
/dev/radio0
/dev/radio1
/dev/vbi0
/dev/vbi1
/dev/swradio0
/dev/media1
HD WebCam: HD WebCam (usb-0000:00:14.0-7):
/dev/video0
/dev/video1
/dev/media0
vedant@pc ~$ v4l2-ctl -d0 --stream-mmap --out-device /dev/video3 --stream-out-dmabuf
VIDIOC_G_FMT returned -1 (Invalid argument)
<VIDIOC_QBUF: failed: Invalid argument
handle out -1
handle out2in -1
While using the --out-device mode g_fmt must be operated on out_fd as
well. determine_field was called on fps_timestamp object for output, but was
not passed out_fd.
This patch fixes the VIDIOC_G_FMT returned -1 (Invalid argument) error.
