Ok, the problem is that MPV 0.13 (my package) was buildet on lubuntu 14.04 and you have 15.10.
Try to compile it:
https://github.com/mpv-player/mp ... r-debian-and-ubuntu
it takes some time but this will build surely a correct package for your system.
Don't forget to remove the broken mpv package before you install the new one.
Before you try to build it from source try to install the mpv package made by @jacer.
I have it uploaded in my shared googledrivefolder:
