The ACX_RT_STREAM_CALLBACKS structure defines callbacks for RT streaming to the ACX framework.
SizeThe length, in bytes, of this structure.
EvtAcxStreamGetHwLatencyThe EvtAcxStreamGetHwLatency callback.
EvtAcxStreamAllocateRtPacketsThe EvtAcxStreamAllocateRtPackets callback.
EvtAcxStreamFreeRtPacketsThe EvtAcxStreamFreeRtPackets callback.
EvtAcxStreamSetRenderPacketThe EvtAcxStreamSetRenderPacket callback.
EvtAcxStreamGetCurrentPacketThe EvtAcxStreamGetCurrentPacket callback.
EvtAcxStreamGetCapturePacketThe EvtAcxStreamGetCapturePacket callback.
EvtAcxStreamGetPresentationPositionThe EvtAcxStreamGetPresentationPosition callback.
The driver must also define and use the ACX_STREAM_CALLBACKS structure to create an ACXRTSTREAM.
Minimum ACX version: 1.0
