GI.GstAudio.Objects.AudioSink

This is the most simple base class for audio sinks that only requires subclasses to implement a set of simple functions:

• open() :Open the device.
• prepare() :Configure the device with the specified format.
• write() :Write samples to the device.
• reset() :Unblock writes and flush the device.
• delay() :Get the number of samples written but not yet played by the device.
• unprepare() :Undo operations done by prepare.
• close() :Close the device.

All scheduling of samples and timestamps is done in this base class together with AudioBaseSink using a default implementation of a AudioRingBuffer that uses threads.

class (GObject o, IsDescendantOf AudioSink o) => IsAudioSink o

Type class for types which can be safely cast to AudioSink, for instance with toAudioSink.

Instances

(GObject o, IsDescendantOf AudioSink o) => IsAudioSink o

toAudioSink :: (MonadIO m, IsAudioSink o) => o -> m AudioSink

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