I used to use dvd::rip [1] (written in perl) that was sort of a similar concept. Deploy transcode jobs onto a cluster of servers accessing a shared filesystem (nfs, smb, etc.). worked really well. I think it used gstreamer though. I set up a homelab of a bunch of pentium 3s that I salvaged from a PC recycler behind my work. They just had a big pile of obsolete computers covered by a tarp. I grabbed a few chassis with working motherboards, and then scrounged around for the best intel CPUs I could find. and memory sticks. I put together a fun little DVD-ripping factory with those machines.
