Settings


Decoder read settings at call IBaseFilter::JoinFilterGraph(). Decoder don't save current settings to registry. For save/load current state of decoder you can use standard IPersistStream approach.

NOTE. You should call IPersistStream methods after insert filter into graph (after IBaseFilter::JoinFilterGraph() call). In opposite case settings will be load from registry (if found) or reset to default.
