IXAudio2VoiceCallback::OnStreamEnd method
Called when the voice has just finished playing a contiguous audio stream.
Syntax
virtual void OnStreamEnd() = 0;
Parameters
This method has no parameters.
Return value
This method does not return a value.
Remarks
OnStreamEnd is triggered when XAudio2 processes an XAUDIO2_BUFFER with the XAUDIO2_END_OF_STREAM flag set. See the IXAudio2SourceVoice::SubmitSourceBuffer method for more information.
The OnStreamEnd callback indicates that XAudio2 has finished consuming the last buffer submitted to the voice. With PCM data, all audio is guaranteed to have been played and the voice can be stopped or destroyed safely.
The OnStreamEnd callback only indicates that an XAUDIO2_BUFFER with the XAUDIO2_END_OF_STREAM flag set has been processed. The callback is strictly informational and does not change the state of the source voice that triggered it. A voice stays in the start state until IXAudio2SourceVoice::Stop is called and will continue to play submitted source buffers and to trigger additional callbacks.
OnStreamEnd is guaranteed to be called just after the last byte of the current buffer has been consumed.
For information about IXAudio2VoiceCallback interface methods, see the XAudio2 Callbacks topic.
