We had an old software at work that would only take a specific file format, and of course the files came from multiple sources, which made it really painful for the users. We transformed a relatively decent desktop into a ffmpeg transcoding machine, which would monitor files incoming from a samba share and it would output the converted file into another samba share. It was just a bunch of scripts and cron jobs but it worked much better than I anticipated and it was mostly maintenance-free.
