Sets the streams to be parsed by the Advanced Systems Format (ASF) splitter.

HRESULT SelectStreams(
  [in] WORD *pwStreamNumbers,
  [in] WORD wNumStreams
);

[in] pwStreamNumbers

An array of variables containing the list of stream numbers to select.

[in] wNumStreams

The number of valid elements in the stream number array.

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code	Description
S_OK	The method succeeded.
E_INVALIDARG	pwStreamNumbers is NULL and wNumStreams contains a value greater than zero.
MF_E_INVALIDSTREAMNUMBER	Invalid stream number was passed in the array.
