Methods / Constructors
Method / Constructor		Defined By
	channel_changed (TunerChannel *channel) : none Called by elements implementing the GstTuner* interface when the current channel changes. Called by elements implementing the GstTuner interface when the current channel changes. Fires the GstTuner::channel-changed signal. Parameters: GstInterfaces.TunerChannel channel Required (not null) Returns: none	GstInterfaces.Tuner
	find_channel_by_name (String *channel) : GstInterfaces.TunerChannel Look up a GstTunerChannel* by name. Look up a GstTunerChannel by name. is available. Parameters: String channel Required (not null) Returns: GstInterfaces.TunerChannel	GstInterfaces.Tuner
	find_norm_by_name (String *norm) : GstInterfaces.TunerNorm Look up a GstTunerNorm* by name. Look up a GstTunerNorm by name. is available. Parameters: String norm Required (not null) Returns: GstInterfaces.TunerNorm	GstInterfaces.Tuner
	frequency_changed (TunerChannel *channel, Number frequency) : none Called by elements implementing the GstTuner* interface when the configured frequency changes. Called by elements implementing the GstTuner interface when the configured frequency changes. Fires the GstTuner::frequency-changed signal on the tuner, and the GstTunerChannel::frequency-changed signal on the channel. Parameters: GstInterfaces.TunerChannel channel Required (not null) Number frequency Required (not null) Returns: none	GstInterfaces.Tuner
	get_channel () : GstInterfaces.TunerChannel Retrieve the current channel from the tuner. Retrieve the current channel from the tuner. Returns: GstInterfaces.TunerChannel	GstInterfaces.Tuner
	get_frequency (TunerChannel *channel) : Number Retrieve the current frequency from the given channel. Retrieve the current frequency from the given channel. As for gst_tuner_set_frequency(), the GstTunerChannel* must support frequency operations, as indicated by the GST_TUNER_CHANNEL_FREQUENCY flag. Parameters: GstInterfaces.TunerChannel channel Required (not null) Returns: Number	GstInterfaces.Tuner
	get_norm () : GstInterfaces.TunerNorm Get the current video norm from the given tuner object for the currently selected channel. Get the current video norm from the given tuner object for the currently selected channel. Returns: GstInterfaces.TunerNorm	GstInterfaces.Tuner
	list_channels () : Array Retrieve a GList of GstTunerChannels available (e.g. Retrieve a GList of GstTunerChannels available (e.g. 'composite', 's-video', ...) from the given tuner object. Returns: Array owned by the GstTuner and must not be freed.	GstInterfaces.Tuner
	list_norms () : Array Retrieve a GList of available GstTunerNorm settings for the currently tuned channel on the given tuner object. Retrieve a GList of available GstTunerNorm settings for the currently tuned channel on the given tuner object. Returns: Array tuner object. The list is owned by the GstTuner and must not be freed.	GstInterfaces.Tuner
	norm_changed (TunerNorm *norm) : none Called by elements implementing the GstTuner* interface when the current norm changes. Called by elements implementing the GstTuner interface when the current norm changes. Fires the GstTuner::norm-changed signal. Parameters: GstInterfaces.TunerNorm norm Required (not null) Returns: none	GstInterfaces.Tuner
	set_channel (TunerChannel *channel) : none Tunes the object to the given channel, which should be one of the channels returned by gst_tuner_list_channels(). Tunes the object to the given channel, which should be one of the channels returned by gst_tuner_list_channels(). Parameters: GstInterfaces.TunerChannel channel* Required (not null) Returns: none	GstInterfaces.Tuner
	set_frequency (TunerChannel *channel, Number frequency) : none Sets a tuning frequency on the given tuner/channel. Sets a tuning frequency on the given tuner/channel. Note that this requires the given channel to be a "tuning" channel, which can be checked using GST_TUNER_CHANNEL_HAS_FLAG (), with the proper flag being GST_TUNER_CHANNEL_FREQUENCY. The frequency is in Hz, with minimum steps indicated by the frequency_multiplicator provided in the GstTunerChannel. The valid range is provided in the min_frequency and max_frequency properties of the GstTunerChannel. Parameters: GstInterfaces.TunerChannel channel* Required (not null) Number frequency Required (not null) Returns: none	GstInterfaces.Tuner
	set_norm (TunerNorm *norm) : none Changes the video norm on this tuner to the given norm, which should be one of the norms returned by gst_tuner_list_norms(). Changes the video norm on this tuner to the given norm, which should be one of the norms returned by gst_tuner_list_norms(). Parameters: GstInterfaces.TunerNorm norm* Required (not null) Returns: none	GstInterfaces.Tuner
	signal_changed (TunerChannel *channel, Number signal) : none Called by elements implementing the GstTuner* interface when the incoming signal strength changes. Called by elements implementing the GstTuner interface when the incoming signal strength changes. Fires the GstTuner::signal-changed signal on the tuner and the GstTunerChannel::signal-changed signal on the channel. Parameters: GstInterfaces.TunerChannel channel Required (not null) Number signal Required (not null) Returns: none	GstInterfaces.Tuner
	signal_strength (TunerChannel *channel) : Number Get the strength of the signal on this channel. Get the strength of the signal on this channel. Note that this requires the current channel to be a "tuning" channel, i.e. a channel on which frequency can be set. This can be checked using GST_TUNER_CHANNEL_HAS_FLAG (), and the appropriate flag to check for is GST_TUNER_CHANNEL_FREQUENCY. The valid range of the signal strength is indicated in the min_signal and max_signal properties of the GstTunerChannel. Parameters: GstInterfaces.TunerChannel channel* Required (not null) Returns: Number	GstInterfaces.Tuner
