IMediaObject::GetInputStreamInfo (Compact 2013)
3/26/2014
This method retrieves information about an input stream, such as any restrictions on the number of samples per buffer, and whether the stream performs a lookahead on the input data. This information never changes.
Syntax
HRESULT GetInputStreamInfo(
DWORD dwInputStreamIndex,
DWORD* pdwFlags
);
Parameters
- dwInputStreamIndex
Zero-based index of an input stream on the DMO.
- pdwFlags
[out] Pointer to a variable that receives a bitwise combination of zero or more DMO_INPUT_STREAM_INFO_FLAGS flags.
Return Value
Returns an HRESULT value. Possible values include the following.

E_POINTER |
NULL pointer argument |
Remarks
The DMO_INPUT_STREAMF_HOLDS_BUFFERS flag indicates that the DMO performs a lookahead on the incoming data.
The application must be sure to allocate sufficient buffers for the DMO to process the input. Call the IMediaObject::GetInputSizeInfo method to determine the buffer requirements.
