Member Function Documentation

static void Gst::StreamVolume::add_interface ( GType  gtype_implementer  )  [static]
static double Gst::StreamVolume::convert_volume ( Gst::StreamVolumeFormat  from,
Gst::StreamVolumeFormat  to,
double  val 
) [static]
Parameters:
from Gst::StreamVolumeFormat to convert from.
to Gst::StreamVolumeFormat to convert to.
val Volume in from format that should be converted.
Returns:
The converted volume
Since gstreamermm 0.10:
.25.
bool Gst::StreamVolume::get_mute (  ) 
Returns:
Returns true if the stream is muted
Since gstreamermm 0.10:
.25.
double Gst::StreamVolume::get_volume ( Gst::StreamVolumeFormat  format  ) 
Parameters:
format Gst::StreamVolumeFormat which should be returned.
Returns:
The current stream volume as linear factor
Since gstreamermm 0.10:
.25.
const GstStreamVolume* Gst::StreamVolume::gobj (  )  const [inline]

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

Reimplemented in Gst::PlayBin2, and Gst::Volume.

GstStreamVolume* Gst::StreamVolume::gobj (  )  [inline]

Provides access to the underlying C GObject.

Reimplemented from Glib::Interface.

Reimplemented in Gst::PlayBin2, and Gst::Volume.

Glib::PropertyProxy_ReadOnly<bool> Gst::StreamVolume::property_mute (  )  const

Mute the audio channel without changing the volume.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Reimplemented in Gst::PlayBin2, and Gst::Volume.

Glib::PropertyProxy<bool> Gst::StreamVolume::property_mute (  ) 

Mute the audio channel without changing the volume.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Reimplemented in Gst::PlayBin2, and Gst::Volume.

Glib::PropertyProxy_ReadOnly<double> Gst::StreamVolume::property_volume (  )  const

Linear volume factor.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Reimplemented in Gst::PlayBin2, and Gst::Volume.

Glib::PropertyProxy<double> Gst::StreamVolume::property_volume (  ) 

Linear volume factor.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Reimplemented in Gst::PlayBin2, and Gst::Volume.

void Gst::StreamVolume::set_mute ( bool  mute  ) 
Since gstreamermm 0.10:
.25
Parameters:
mute Mute state that should be set.
void Gst::StreamVolume::set_volume ( Gst::StreamVolumeFormat  format,
double  val 
)
Since gstreamermm 0.10:
.25
Parameters:
format Gst::StreamVolumeFormat of val.
val Linear volume factor that should be set.
