Can the  N7 play MKV files and avi files?

Accoring to my 3+ month's using experience on my N7, the MKV files cannot be supported natively, and .avi files mainly denpend on the codecs contained, like the divx is not the compatible codec for N7. At the begining, I tried the MX player, but sometimes, the MKV files still can't be played well, like no audio just pictures. I googled the solution and find a relevent post shows us the solution to play mkv, avi, flv, and some other files on Nexus 7 without any issues. I've tried and made it.

I'm working out a solution now.
