Just wondering if anyone has implemented AVIkit and is willing to part with
the code :) or if AVIkit has been used in any open source mods (rebirth and
arrangemod have the lib's included but don't actually call the functions).
I'd do it myself but it would literally take years (I'm a moron), it'd be
easier just to ask for it here just incase any devs have a dead hl1 mod with
the code already laid out :)
I've scoured the internet and all I could find was this on a russian HL
coding site which seems to use the code but I'm not sure if it's an entire
replacement for avikit.cpp or if it fits in there somehow (again I'm a moron
when it comes to this)

Regardless of this, the AVIkit mod also included fmod.dll, which I'm
guessing is used for sound and I'm not sure how it pulls this from the AVI.
