HRESULT GetInputStatus(DWORDdwInputStreamIndex,DWORD* dwFlags);
Parameters
- dwInputStreamIndex
Zero-based index of an input stream on the DMO. - dwFlags
[out] Pointer to a variable that receives either zero or DMO_INPUT_STATUSF_ACCEPT_DATA.
Return Values
Returns an HRESULT value. Possible values include the following.
| Value | Description |
|---|---|
| S_OK | Success |
| DMO_E_INVALIDSTREAMINDEX | Invalid stream index |
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
