GstAudioSink* | gobj () |
Provides access to the underlying C GObject. | |
const GstAudioSink* | gobj () const |
Provides access to the underlying C GObject. | |
GstAudioSink* | gobj_copy () |
Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs. | |

vfunc to open the device. | |
virtual bool | prepare_vfunc (Gst::RingBufferSpec& spec) |
vfunc to prepare the device to operate with the specified parameters. | |
virtual bool | unprepare_vfunc () |
vfunc to undo operations done in prepare. | |
virtual bool | close_vfunc () |
vfunc to close the device. | |
virtual guint | write_vfunc (const void* data, guint length) |
vfunc to write data to the device. | |
virtual guint | get_delay_vfunc () const |
vfunc to return how many samples are still in the device. | |
virtual void | reset_vfunc () |
vfunc to return as quickly as possible from a write and flush any pending samples from the device. | |

A simple base class for audio sinks.
This is the most simple base class for audio sinks that only requires subclasses to implement a set of simple virtual functions:
All scheduling of samples and timestamps is done in this base class together with Gst::BaseAudioSink using a default implementation of a Gst::RingBuffer that uses threads.
