"Media center" is just a media center Including XBMC and others.
People usually what to interact with them using remotes instead of mouse & keyboard.
So by "improving usability for media center users" I mean "add more informative and may be even interactive OSD".
Vapoursynth support is not a big problem, but I really don't think mpv is "user friendly" in any way.
Besides SVP needs to interact with the player on-the-fly, and I just don't know now if it possible with mpv.
I need to dig into it first
I wanted to know on which technologies you work at the moment for the next svp release since there is nothing about it on the indiegogo page, just "but is a subject to 3rd party dependencies" (wich ones) and "up to 40% better" (what makes this possible) inside the more technical table.
