GI.GstAudio.Objects.AudioSrc

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.

class (GObject o, IsDescendantOf AudioSrc o) => IsAudioSrc o

Type class for types which can be safely cast to AudioSrc, for instance with toAudioSrc.

Instances

(GObject o, IsDescendantOf AudioSrc o) => IsAudioSrc o

Defined in GI.GstAudio.Objects.AudioSrc

toAudioSrc :: (MonadIO m, IsAudioSrc o) => o -> m AudioSrc

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