WM_STREAM_PRIORITY_RECORD 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 It has been superseded by Source Reader and Sink Writer.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 WM_STREAM_PRIORITY_RECORD structure contains a stream number and specifies whether delivery of that stream is mandatory.
Syntax
typedef struct _WMStreamPrioritizationRecord {
WORD wStreamNumber;
BOOL fMandatory;
} WM_STREAM_PRIORITY_RECORD;
Members
wStreamNumber
WORD containing the stream number.
fMandatory
Flag indicating whether the listed stream is mandatory. Mandatory streams will not be dropped regardless of their position in the priority list.
Remarks
WM_STREAM_PRIORITY_RECORD is used in an array by the IWMStreamPrioritization interface. Each member of the array specifies a stream; the lower the element number in the array, the higher the priority of the stream.
