GI.GstAudio.Objects.AudioSrc
Contents
Description
This is the most simple base class for audio sources that only requires subclasses to implement a set of simple functions:
open():Open the device.prepare():Configure the device with the specified format.read():Read samples from the device.reset():Unblock reads and flush the device.delay():Get the number of samples in the device but not yet read.unprepare():Undo operations done by prepare.close():Close the device.
All scheduling of samples and timestamps is done in this base class
together with AudioBaseSrc using a default implementation of a
AudioRingBuffer that uses threads.
Synopsis
- newtype AudioSrc = AudioSrc (ManagedPtr AudioSrc)
- class GObject o => IsAudioSrc o
- toAudioSrc :: (MonadIO m, IsAudioSrc o) => o -> m AudioSrc
- noAudioSrc :: Maybe AudioSrc
Exported types
Memory-managed wrapper type.
