eAVDecVideoInputScanType 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 how the decoded video stream is interlaced. This enumeration is used with the AVDecVideoInputScanType property.

  eAVDecVideoInputScan_Unknown = 0,
  eAVDecVideoInputScan_Progressive = 1,
  eAVDecVideoInputScan_Interlaced_UpperFieldFirst = 2,
  eAVDecVideoInputScan_Interlaced_LowerFieldFirst = 3
} ;
