This is the last chapter describing the evolution of the audio transcoding server. In this last chapter, two more areas will be detailed—how to handle dynamic configuration and how to manage errors correctly. This chapter is composed of four parts. The first one explains how one can monitor changes in a file. The second part details the new operators that are needed to implement such a feature. The third part covers the implementation of this feature in the encode server. Finally, the last part shows you a smarter way to handle errors than the current one.

The following topics will be covered in this chapter:

• Monitoring file changes
• Operators used for dynamic configuration
• Encode driver reconfiguration
• Error management
