eAVEncAudioDualMono enumeration (codecapi.h)

  • Article

[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 2-channel audio is encoded as stereo or dual mono. This enumeration is used with the AVEncAudioDualMono property.

Syntax

typedef enum eAVEncAudioDualMono {
  eAVEncAudioDualMono_SameAsInput = 0,
  eAVEncAudioDualMono_Off = 1,
  eAVEncAudioDualMono_On = 2
} ;

Constants

eAVEncAudioDualMono_Off
