changing device with v4l2-ctl is not working

Question

I have a WinTV HVR 1900 TV tuner runnning on Ubuntu 13.10, from which I would like to capture S-VIDEO input. The device is supported, based on LinuxTV. As is written here, it seems that that kind of device defaults to the tuner input, and that a change of input is therefore needed. This is also supported by the fact that trying to read the output stream with VLC using terminal command

cat /dev/video1 > test.mpg

and opening the resulting file does succeed in opening the stream, but since there is no signal I see only a black screen. I am quite sure that my system handles the device correctly, and

/dev/video1

does indeed exist (my integrated webcam holds the video0 slot).

My problem is that trying to change devices through terminal command

v4l2-ctl -d 1

as exposed here yields no error, but seems to do nothing.

Can anyone please help me here?

Terminal session:

raoul@raoul-EasyNote-LS11HR:~$ v4l2-ctl -I

raoul@raoul-EasyNote-LS11HR:~$ v4l2-ctl -d 1

Solution

Ok I made it... In a single line:

raoul@raoul-EasyNote-LS11HR:~$ v4l2-ctl -d /dev/video1 -i 2
Video input set to 2 (s-video: ok)
raoul@raoul-EasyNote-LS11HR:~$ cat /dev/video1>test.mpg

although I do not quite understand what difference it makes from the input I previously posted... it would seem that one needs to define the input type at the same time as the device switch.
