Ivtvctl old
From IVTV
(Redirected from Ivtvctl)
In the newer releases of ivtv (>=ivtv-0.8) most these options have been moved to v4l2-ctl. The syntax should be almost the same
ivtvctl is a utility that can control many card settings, like changing the inputs from tuner to svideo or composite, setting video resolution or changing video mode (PAL, SECAM, NTSC).
It is included in the ivtv source under the utils directory, and is installed with make install. Most non-ivtv specific options (such as selecting inputs, etc) have been moved into 'v4l2-ctl' utility, and ivtvctl now only has settings specific to ivtv.

-a --all display all information available
-B --get-vbi query the current VBI mode [IVTV_G_VBI_MODE]
-b --set-vbi=<mode> set the current VBI mode [IVTV_S_VBI_MODE]
