[QUOTE="tourettes, post: 505504, member: 10858"] In MediaPortal the graph building works in following way: 1) MediaPortal loads all configured codecs (that user has selected in player settings) into the diretcshow graph 2) MediaPortal asks the directshow to render the output pins of the souce filter At that point the control is completely on directshow side. Basicy that means that the codec selection is not 100% explicit. For example if the graph has multiple codecs that are able to decode MPEG2 stream it is up to directshow to decide what codec will be connected. Directshow will always prefer the loaded codecs and if none of those are capable of handling the stuff then the non-loaded codecs are checked next. In short following rules are used when connecting the filters (by directshow): 1. loaded filters are tried to connect by their merits 2. if there are still undendered pins all available directshow filters are tried to connect (order is again based on the merit values) [/QUOTE]
