This method queries whether an input stream can accept more input data.
Syntax
HRESULT GetInputStatus(
DWORD dwInputStreamIndex,
DWORD* dwFlags
);
Parameters
- dwInputStreamIndex

Remarks
If the input stream will accept more data, the method returns the DMO_INPUT_STATUSF_ACCEPT_DATA flag in the dwFlags parameter. Otherwise, it sets this parameter to zero.
If the stream will accept more data, the application can call the IMediaObject::ProcessInput method.
The status of an input stream can change only as the result of one of the following method calls:
- IMediaObject::Discontinuity
- IMediaObject::Flush
- IMediaObject::ProcessInput
- IMediaObject::ProcessOutput
