[gst-devel] [dshwovideosrc] Composite S-Video Tuner

"GstTuner is an interface for controlling capture devices with tuners"
</quote>

We are ok, a video capture device have not necessary a tuner. For example,
my video capture device have not a tuner (and no tuner input by the way),
and have S-video, composite and vga inputs.

So it is strange if I use GstTuner interface with a NO-tuner video capture
device.


Thx
