AMVAUncompDataInfo structure (amva.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 AMVAUncompDataInfo structure specifies the dimensions and pixel format of the uncompressed surfaces for DirectX Video Acceleration (DXVA) video decoding.

Syntax

typedef struct _tag_AMVAUncompDataInfo {
  DWORD         dwUncompWidth;
  DWORD         dwUncompHeight;
  DDPIXELFORMAT ddUncompPixelFormat;
} AMVAUncompDataInfo, *LPAMVAUncompDataInfo;

Members

dwUncompWidth

Width of the decoded, uncompressed data, in pixels.

dwUncompHeight

Height of the decoded, uncompressed data, in pixels.

ddUncompPixelFormat

A DDPIXELFORMAT structure that specifies the pixel format of the uncompressed data.
