Gets the current media type for an output stream on this Media Foundation transform (MFT).
Output stream identifier. To get the list of stream identifiers, call IMFTransform::GetStreamIDs.
Receives a pointer to the IMFMediaType interface. The caller must release the interface.
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |
|---|---|
|
The method succeeded. |
|
Invalid stream identifier. |
|
The output media type has not been set. |
If the specified output stream does not yet have a media type, the method returns MF_E_TRANSFORM_TYPE_NOT_SET. Most MFTs do not set any default media types when first created. Instead, the client must set the media type by calling IMFTransform::SetOutputType.
If MFT_UNIQUE_METHOD_NAMES is defined before including mftransform.h, this method is renamed MFTGetOutputCurrentType. See Creating Hybrid DMO/MFT Objects.
The MFT should return a clone of the media type, not a pointer to the original type. Otherwise, the caller might modify the type and alter the internal state of the MFT.
