Implemented Interfaces

GESAudioTestSource implements GESExtractable and GESMetaContainer.

Description

Outputs a test audio stream using audiotestsrc. The default property values output silence. Useful for testing pipelines, or to fill gaps in an audio track.

typedef struct _GESAudioTestSource GESAudioTestSource;

ges_audio_test_source_set_freq ()

void                ges_audio_test_source_set_freq      (GESAudioTestSource *self,
                                                         gdouble freq);

Lets you set the frequency applied on the track element

self :

a GESAudioTestSource

freq :

The frequency you want to apply on self

ges_audio_test_source_set_volume ()

void                ges_audio_test_source_set_volume    (GESAudioTestSource *self,

Sets the volume of the test audio signal.

self :

a GESAudioTestSource

volume :

The volume you want to apply on self

ges_audio_test_source_get_freq ()

double              ges_audio_test_source_get_freq      (GESAudioTestSource *self);

Get the current frequency of self.

self :

a GESAudioTestSource

Returns :

The current frequency of self.
