Good PPA for ffmpeg

Its annoying that the default ffmpeg in ubuntu's repositories is outdated and hobbled for legal reasons, however, there's a great page on the forums that walks you through building it from scratch: http://ubuntuforums.org/showthread.php?t=786095 (I also add in support for --enable-libdc1394 --enable-libgsm --enable-libopenjpeg --enable-libschroedinger --enable-libspeex when I build, which is nice, but not essential.)

Anyway, I'm getting set to setup a computer lab running ubuntu for a multimedia class I'm teaching, and I was wondering if there was PPA out there that did something similar to what is available when building from scratch. The things I absolutely need from it are up-to-date libxvid, libx264, libfaac, and libmp3lame support plus the un-encumbered stuff (vorbis, theora, vpx).

Is there a PPA out there that provides something like this?

For older releases we may be able to install the libavcodec-extra-52 package from Medibuntu that includes ffmpeg 0.6. Newer Ubuntu versions are supported from Medibuntu with the libavcodec-extra-53-library.

Note that recent Ubuntu versions have libavcode-extra-53 together with ffmpeg or avconv installable from the repositories too.

According to http://www.ffmpeg.org/download.html

FFmpeg Ubuntu packages for Precise, Oneiric, Natty, Maverick, and Lucid (amd64, i386) are available at Jon Severinsson's FFmpeg PPA.

I don't think there can be any better PPA than this ;)
