 // FilterHost describes an interface for individual filters to access and
 // modify global playback information.  Every filter is given a filter host
 // reference as part of initialization.
 //
 // This interface is intentionally verbose to cover the needs for the different
 // types of filters (see media/base/filters.h for filter definitionss).  Filters
 // typically use parts of the interface that are relevant to their function.
 // For example, an audio renderer filter typically calls SetTime as it feeds
 // data to the audio hardware.  A video renderer filter typically calls GetTime
 // to synchronize video with audio.  An audio and video decoder would typically
 // have no need to call either SetTime or GetTime.
