AVI files are not designed to be played on OSX : at least not anymore, since Apple video library are in 64-bits (AVFoundation).
Millumin cannot read them directly, so they have to be converted. We tried to support as many codec as possible to handle the right conversion (with or without alpha), but it's impossible to cover all : in your case, you're using the "Basic Windows bitmap format" codec, which is not very friendly (so Millumin convert it by default withour alpha).
In brief : convert your AVI files with Premiere or any softwares to do so, and ask it to convert it, ProRes-4444.
More info regarding codec here.
