EncoderLink Class Reference

#include <encoderlink.h>

Detailed Description

Provides an interface to both local and remote TVRec's for the mythbackend.

This class be instanciated for either a local or remote TVRec's. Many of the methods will work with either, but many only work for a local TVRec's and these are labeled appropriately in this document.

When used with a remote TVRec all calls go through a PlaybackSock instance.

This class is used primarily by the MainServer, Scheduler and AutoExpire classes.
