I want to batch convert a directory containing hundreds of FLV files so that each file has a MP4 equivalent.

In the past we have used Adobe Media Encoder (AME) CS4, but we are working with *.VOB files this time, and AME CS4 does not support them.

I'm working on a little web app that uses Firefox 4's Audio Data API to manipulate raw audio samples. I'd like the user to be able to supply their own source material, but unfortunately Firefox 4 doesn't currently support mp3s in Audio elements.
