  [in] DWORD dwMutexNum,
  [in] WORD  wSelectedRecord
);

Parameters

Return code Description
S_OK
 The method succeeded.

Remarks

An output is a stream in an Advanced Systems Format (ASF) data section that will be parsed. If mutual exclusion is used, mutually exclusive streams share the same output.

An ASF file can contain multiple mutually exclusive relationships, such as a file with both language based and bit-rate based mutual exclusion. If an output is involved in multiple mutually exclusive relationships, a record from each must be selected.
