A system includes a memory, processors, and an asset player module configured to identify a playable asset configuration for a first playable asset, including a first graph configuration identifying processing nodes and edges, each node in the graph configuration represents a media processing component configured to modify media inputs to generate a media output, construct a graph in the memory based on the first graph configuration, receive a first set of media inputs, execute the media processing components in an order based on the graph configuration and using the first set of media inputs as the one or more input media components, based on said executing, generate a media output configured to be played by a conventional media player, alter the graph at runtime, thereby changing the media processing components identified within the graph, and execute the media processing components of the graph after the altering.
