Easy or not, On2 presumably already did it.  MEncoder is the program
behind their "Flix Engine" Linux SDK (no doubt the app running behind
the scenes at YouTube). And to make things even easier, you can download
a free demo (which thereby gives you the right to request the source
code, with all modifications they've made).

copy of the source code for any of the Open Source Software for the cost
of performing the distribution."
