IWMWriter::SetInputProps method (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 It has been superseded by Source Reader and Sink Writer.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 SetInputProps method specifies the media properties of an input stream.
Syntax
HRESULT SetInputProps(
[in] DWORD dwInputNum,
[in] IWMInputMediaProps *pInput
);
Parameters
[in] dwInputNum
DWORD containing the input number.
[in] pInput
Pointer to an IWMInputMediaProps interface. See Remarks.
Return value
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |
|---|---|
|
The method succeeded. |
|
dwInputNum is greater than the highest index number. |
|
There is not enough available memory. |
|
The method failed for an unspecified reason. |
Remarks
Manipulating the IWMInputMediaProps object has no effect on the writer until the application calls this method to configure the input.
Specify NULL for pInput if the input contains compressed samples that will be written directly to the new stream (using IWMWriterAdvanced::WriteStreamSample) without being recompressed.
