OpenAL Tizen

---

OpenAL is open source for audio play. Various user applications or audio related modules can invoke OpenAL api in Tizen.

Required Header

Overview

As Tizen Audio Framework works with stream information concept since 3.0, OpenAL needs to be integrated with stream information.
The function "alcOpenDeviceNew" is same as alcOpenDevice() with addition of "StreamType" and "StreamIndex" fields to Device structure.

Remarks :

• 2 additional variables are added to the structure "ALCdevice_struct" in the existing Header file "OpenAL32/Include/alMain.h"
  

  Remarks:

  ALuint StreamIndex;
  ALchar *StreamType;
  

• 1 function needs to be added in "include/AL/alc.h".
