DVD_MultichannelAudioAttributes structure (strmif.h)

[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The DVD_MultichannelAudioAttributes structure describes the multichannel attributes of one audio stream within a specified title.

Syntax

typedef struct tagDVD_MultichannelAudioAttributes {
  DVD_MUA_MixingInfo Info[8];
  DVD_MUA_Coeff      Coeff[8];
} DVD_MultichannelAudioAttributes;

Members

Info[8]

Array of eight DVD_MUA_MixingInfo structures, which contain the mixing information for each channel in the audio stream.

Coeff[8]

Array of eight DVD_MUA_Coeff structures, which contain the mixing coefficients for each channel in the audio stream.

Remarks

The DVD_TitleAttributes structure contains an array of up to eight DVD_MultichannelAudioAttributes structures. When DVD_TitleAttributes is filled by a call to the IDvdInfo2::GetTitleAttributes method, the array will be populated with one DVD_MultichannelAudioAttributes structure for each available audio stream in the title.
