설명

예제

사용 예제는 다음과 같습니다.

        ACX_STREAMAUDIOENGINE_CALLBACKS streamAudioEngineCallbacks;

        // Create the AudioEngine element to control offloaded streaming.
        ACX_STREAMAUDIOENGINE_CALLBACKS_INIT(&streamAudioEngineCallbacks);

        streamAudioEngineCallbacks.EvtAcxStreamAudioEngineAssignEffectsState = CodecR_EvtAcxStreamAudioEngineAssignEffectsState;
        streamAudioEngineCallbacks.EvtAcxStreamAudioEngineRetrieveEffectsState = CodecR_EvtAcxStreamAudioEngineRetrieveEffectsState;
        streamAudioEngineCallbacks.EvtAcxStreamAudioEngineRetrievePresentationPosition = CodecR_EvtAcxStreamAudioEngineRetrievePresentationPosition;
        streamAudioEngineCallbacks.EvtAcxStreamAudioEngineAssignCurrentWritePosition = CodecR_EvtAcxStreamAudioEngineAssignCurrentWritePosition;
        streamAudioEngineCallbacks.EvtAcxStreamAudioEngineRetrieveLinearBufferPosition = CodecR_EvtAcxStreamAudioEngineRetrieveLinearBufferPosition;
        streamAudioEngineCallbacks.EvtAcxStreamAudioEngineAssignLastBufferPosition = CodecR_EvtAcxStreamAudioEngineAssignLastBufferPosition;
