interesting. I'm inclined to try those two too, since it seems they have some stuff `mpv` doesn't...
For example, the 3D contents support on sview, it seems like if you were to run 3D content on mpv, it would use more cpu/ram than usual.
I guess sview does some weird optimization on the background/under the hood?
And yeah, mpv is basically pretty minimalist, so there isn't much UI buttons (keyboard centric basically) though there is some basic one, but not as advanced as BSPlayer.
