That template works with the TimedMediaHandler extension (via a Lua Module), which only plays OGG files (you can convert MP3 files to OGG if you need to), and that would be far easier to install.
If you want, I could easily do that.
It also supports a few other related formats, and any formats it doesn't support will need the files converted for uploading or linked to places with TimedMediaHandler friendly formatting.

P.S. - Places like Youtube offer links in TMH friendly formats, as do some other audio/video hosting services.
