WMT_PAYLOAD_FRAGMENT 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 It has been superseded by Source Reader and Sink Writer.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_PAYLOAD_FRAGMENT structure contains the information needed to extract a payload fragment from a buffer and identifies the payload to which the fragment belongs. An array of WMT_PAYLOAD_FRAGMENT structures is used as a member of the WMT_FILESINK_DATA_UNIT structure to provide access to each payload fragment in a packet.
Syntax
typedef struct _WMT_PAYLOAD_FRAGMENT {
DWORD dwPayloadIndex;
WMT_BUFFER_SEGMENT segmentData;
} WMT_PAYLOAD_FRAGMENT;
Members
dwPayloadIndex
DWORD containing the payload index. This identifies the payload item to which this fragment belongs.
segmentData
A WMT_BUFFER_SEGMENT structure specifying the buffer segment containing the payload fragment.
