HEAACWAVEFORMAT Structure

[This documentation is preliminary and is subject to change.]

Contains format data for an AAC or HE-AAC stream that includes AudioSpecificConfig() data.

Syntax

typedef struct heaacwaveformat_tag {
  HEAACWAVEINFO wfInfo;
  BYTE pbAudioSpecificConfig[1];
} HEAACWAVEFORMAT, 
 *PHEAACWAVEFORMAT;

Members

  • wfInfo
    A HEAACWAVEINFO structure.

  • pbAudioSpecificConfig
    A byte array that contains the value of AudioSpecificConfig(), as defined by ISO/IEC 14496-3. The array might be larger than the size given in the structure declaration. Use the value of wfInfo.wfx.cbSize to determine the size.
