GI.GstAudio.Objects.AudioBaseSrc

This is the base class for audio sources. Subclasses need to implement the ::create_ringbuffer vmethod. This base class will then take care of reading samples from the ringbuffer, synchronisation and flushing.

Methods

createRingbuffer

audioBaseSrcCreateRingbuffer

Arguments

:: (HasCallStack, MonadIO m, IsAudioBaseSrc a)

=> a

src: a AudioBaseSrc.

-> m AudioRingBuffer

Returns: The new ringbuffer of src.

Create and return the AudioRingBuffer for src. This function will call the ::create_ringbuffer vmethod and will set src as the parent of the returned buffer (see objectSetParent).

getProvideClock

audioBaseSrcGetProvideClock

Arguments

:: (HasCallStack, MonadIO m, IsAudioBaseSrc a)

=> a

src: a AudioBaseSrc

-> m Bool

Returns: True if src will provide a clock.

Queries whether src will provide a clock or not. See also gst_audio_base_src_set_provide_clock.

getSlaveMethod

audioBaseSrcGetSlaveMethod

Arguments

:: (HasCallStack, MonadIO m, IsAudioBaseSrc a)

=> a

src: a AudioBaseSrc

-> m AudioBaseSrcSlaveMethod

Returns: The current slave method used by src.

Get the current slave method used by src.

setProvideClock

audioBaseSrcSetProvideClock

Arguments

:: (HasCallStack, MonadIO m, IsAudioBaseSrc a)

=> a

src: a AudioBaseSrc

-> Bool

provide: new state

-> m ()

Controls whether src will provide a clock or not. If provide is True, elementProvideClock will return a clock that reflects the datarate of src. If provide is False, elementProvideClock will return NULL.

setSlaveMethod

audioBaseSrcSetSlaveMethod

Arguments

:: (HasCallStack, MonadIO m, IsAudioBaseSrc a)

=> a

src: a AudioBaseSrc

-> AudioBaseSrcSlaveMethod

method: the new slave method

-> m ()

Controls how clock slaving will be performed in src.
