// EncoderJobProcessingManager.h: interface for the CEncoderJobProcessingManager class.
// Author: Torsten Landmann
//
// manages the actual processing of one encoder job at a time. Note that this
// class doesn't properly process encoder jobs that have a file mask set
// as input file. Callers must filter out these jobs before using this class.
