Default All cast .avi video support from my android

I'm finding that I can't cast .avi files with Allcast. Will there's be any support? Mp4 files are tye only vireo types I see. Further more, I've tried a lot of other cast apps for .avi files on my android nexus 7 and they just give a black screen and broken audio. Anyone had any success? Do tell! :P

Thanks.
