MTD (the Myth Transcoding Daemon)

The MTD is a simple program that is used by the MythVideo plugin.

It currently only transcodes tracks from DVDs, but could in the future also rip CD/VCD tracks, transcode TV recordings, et cetera.

The DVD Rip screen will offer to start MTD if it is not running. It does not currently shut it down afterwards, though.

By default, the MTD listens on port 2442, for commands of this format:

halt
quit
shutdown

• Tells the MTD to wait for all jobs to finish, stop listening, and exit.

hello

• Send a trivial response if the MTD is listening.
