GI.GstPbutils.Objects.AudioVisualizer

A baseclass for scopes (visualizers). It takes care of re-fitting the audio-rate to video-rate and handles renegotiation (downstream video size changes).

It also provides several background shading effects. These effects are applied to a previous picture before the render() implementation can draw a new frame.

Exported types

class (GObject o, IsDescendantOf AudioVisualizer o) => IsAudioVisualizer o

Type class for types which can be safely cast to AudioVisualizer, for instance with toAudioVisualizer.

Instances

(GObject o, IsDescendantOf AudioVisualizer o) => IsAudioVisualizer o

Defined in GI.GstPbutils.Objects.AudioVisualizer

toAudioVisualizer :: (MonadIO m, IsAudioVisualizer o) => o -> m AudioVisualizer

Cast to AudioVisualizer, for types for which this is known to be safe. For general casts, use castTo.

noAudioVisualizer :: Maybe AudioVisualizer

A convenience alias for Nothing :: Maybe AudioVisualizer.

Properties

shadeAmount

No description available in the introspection data.

constructAudioVisualizerShadeAmount :: IsAudioVisualizer o => Word32 -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “shade-amount” property. This is rarely needed directly, but it is used by new.

getAudioVisualizerShadeAmount :: (MonadIO m, IsAudioVisualizer o) => o -> m Word32

Get the value of the “shade-amount” property. When overloading is enabled, this is equivalent to

get audioVisualizer #shadeAmount

setAudioVisualizerShadeAmount :: (MonadIO m, IsAudioVisualizer o) => o -> Word32 -> m ()

Set the value of the “shade-amount” property. When overloading is enabled, this is equivalent to

set audioVisualizer [ #shadeAmount := value ]

shader

No description available in the introspection data.

constructAudioVisualizerShader :: IsAudioVisualizer o => AudioVisualizerShader -> IO (GValueConstruct o)

Construct a GValueConstruct with valid value for the “shader” property. This is rarely needed directly, but it is used by new.

getAudioVisualizerShader :: (MonadIO m, IsAudioVisualizer o) => o -> m AudioVisualizerShader

Get the value of the “shader” property. When overloading is enabled, this is equivalent to

get audioVisualizer #shader

setAudioVisualizerShader :: (MonadIO m, IsAudioVisualizer o) => o -> AudioVisualizerShader -> m ()

Set the value of the “shader” property. When overloading is enabled, this is equivalent to

set audioVisualizer [ #shader := value ]
