* A callback used by MediaResource (sub-classes like FileMediaResource,
* RtspMediaResource, and ChannelMediaResource) to notify various events.
* Currently this is implemented by MediaDecoder only.
*
* Since this class has no pure virtual function, it is convenient to write
* gtests for the readers without using a mock MediaResource when you don't
* care about the events notified by the MediaResource.
