MPEG1VIDEOINFO structure (amvideo.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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 MPEG1VIDEOINFO structure describes an MPEG-1 video stream.

Syntax

  VIDEOINFOHEADER hdr;
  DWORD           dwStartTimeCode;
  DWORD           cbSequenceHeader;
  BYTE            bSequenceHeader[1];
} MPEG1VIDEOINFO;
