eAVEncMPVQScaleType 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 quantizer scale is linear or non-linear. This enumeration is used with the AVEncMPVQScaleType property.

Syntax

typedef enum eAVEncMPVQScaleType {
  eAVEncMPVQScaleType_Auto = 0,
