MarsSeed [1] filed a deletion request for fastoggenc [2]: Abandoned, unused Python2 script, last release in 2010, for media file conversion.
I recommend deletion, as there are maintained alternatives with even better features and customizability. And there don't seem to be any active users of this. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/fastoggenc/
