IMFQualityAdvise interface

Enables the quality manager to adjust the audio or video quality of a component in the pipeline.

This interface is exposed by pipeline components that can adjust their quality. Typically it is exposed by decoders and stream sinks. For example, the enhanced video renderer (EVR) implements this interface. However, media sources can also implement this interface.

To get a pointer to this interface from a media source, call IMFGetService::GetService with the service identifier MF_QUALITY_SERVICES. For all other pipeline objects (transforms and media sinks), call QueryInterface.
