Detailed Description

A channel from an element implementing the Gst::Tuner interface.

The Gst::TunerChannel object is provided by an element implementing the Gst::Tuner interface.

Gst::TunerChannel provides a name and flags to determine the type and capabilities of the channel. If the Gst::TUNER_CHANNEL_FREQUENCY flag is set, then the channel also information about the minimum and maximum frequency, and range of the reported signal strength.
