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:

<variablelist> <varlistentry> <term>open()</term> <listitem><para>Open the device.</para></listitem> </varlistentry> <varlistentry> <term>prepare()</term> <listitem><para>Configure the device with the specified format.</para></listitem> </varlistentry> <varlistentry> <term>write()</term> <listitem><para>Write samples to the device.</para></listitem> </varlistentry> <varlistentry> <term>reset()</term> <listitem><para>Unblock writes and flush the device.</para></listitem> </varlistentry> <varlistentry> <term>delay()</term> <listitem><para>Get the number of samples written but not yet played by the device.</para></listitem> </varlistentry> <varlistentry> <term>unprepare()</term> <listitem><para>Undo operations done by prepare.</para></listitem> </varlistentry> <varlistentry> <term>close()</term> <listitem><para>Close the device.</para></listitem> </varlistentry> </variablelist>

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.
