Callback interface for the Microsoft Media Foundation sink writer.
When to implement
Implement this interface if you use the IMFSinkWriter interface and want to receive asynchronous notifications.
The IMFSinkWriterCallback interface inherits from the IUnknown interface. IMFSinkWriterCallback also has these types of members:
The IMFSinkWriterCallback interface has these methods.
Called when the IMFSinkWriter::Finalize method completes.
Called when the IMFSinkWriter::PlaceMarker method completes.
Set the callback pointer by setting the MF_SINK_WRITER_ASYNC_CALLBACK attribute when you first create the sink writer.
The callback methods can be called from any thread, so an object that implements this interface must be thread-safe.
This interface is available on Windows Vista if Platform Update Supplement for Windows Vista is installed.
