eAVDDSurroundMode enumeration (codecapi.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]

Specifies whether the audio is encoded in Dolby Surround. This enumeration is used with the AVDDSurroundMode property.

Syntax

typedef enum eAVDDSurroundMode {
  eAVDDSurroundMode_NotIndicated = 0,
  eAVDDSurroundMode_No = 1,
  eAVDDSurroundMode_Yes = 2
} ;

Constants

Remarks

If the audio stream is Dolby AC-3, this property reflects the value of the dsurmod field in the bit stream.

If the audio stream is any other format, the value is eAVDDSurroundMode_No.
