WMT_BUFFER_SEGMENT structure (wmsdkidl.h)

[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The WMT_BUFFER_SEGMENT structure contains the information needed to specify a segment in a buffer. It is used as a member of the WMT_FILESINK_DATA_UNIT and WMT_PAYLOAD_FRAGMENT structures to specify segments of a packet.

Syntax

typedef struct _WMT_BUFFER_SEGMENT {
  INSSBuffer *pBuffer;
  DWORD      cbOffset;

} WMT_BUFFER_SEGMENT;

Members
