IMFSinkWriterCallback interface (mfreadwrite.h)
Callback interface for the Microsoft Media Foundation sink writer.
The IMFSinkWriterCallback interface inherits from the IUnknown interface. IMFSinkWriterCallback also has these types of members:
The IMFSinkWriterCallback interface has these methods.
|IMFSinkWriterCallback::OnFinalize||Called when the IMFSinkWriter::Finalize method completes.|
|IMFSinkWriterCallback::OnMarker||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.
