Methods and systems are provided for predicting an event's occurrence and
notifying one or more interested applications that an event has been
predicted to have occurred. The events are associated with media content
samples that are to be rendered on a computing device. Multiple filters
are provided and define a filter graph. The filter graph is configured to
process multiple media content samples and includes one or more render
filters that render the media content samples. An event prediction
module, associated with the filter graph, receives event notification
requests from an application and predicts rendition times associated with
the individual events. Event notifications are sent to the application in
accordance with the predictions that are made. The event prediction
module can be located upstream of the render filters and can include part
of one of the filters in the filter graph such as a source filter.
