This structure describes an MPEG-2 video stream.

Syntax

typedef struct tagMPEG2VIDEOINFO {
  VIDEOINFOHEADER2 hdr;
  DWORD dwStartTimeCode;
  DWORD cbSequenceHeader;
  DWORD dwProfile;
  DWORD dwLevel;
  DWORD dwFlags;
  DWORD dwSequenceHeader[1];
} MPEG2VIDEOINFO;

Members

  • dwStartTimeCode
    25-bit "group-of-pictures" time code at start of data.
  • cbSequenceHeader
    Length in bytes of dwSequenceHeader.
  • dwProfile
    MPEG2Profile enumerated type member.
  • dwLevel
    MPEG2Level enumerated type member.
  • dwFlags
    Flag indicating preferences. Set one or a combination of the following values.

    Value Description
