Some extra configurations are ignored

[7system7]

Overview Description:

I have default mpv config files here: ~/.config/mpv/mpv.conf Some lines are ignored, i.e. the vo even if I try to add it in command line:

$ celluloid --mpv-vo=gpu-next --mpv-gpu-api=vulkan --mpv-hwdec=vaapi <video-file>

Or here

Or here

)

Steps to Reproduce:

1. Add mpv extra config
2. Play a H.265 (Main 10 Profile) video file and it won't be clear.

Actual Results:

There is a bug around on my machine and it cannot play H.265 (Main 10 Profile) w/o flickering. So I have to add extra configuration to play it clearly. And actually, through the vaapi the cpu using is 10x less.

Expected Results:

With mpv player only, I can play video files clearly if I add my config here ~/.config/mpv/mpv.conf or in cli too.

Version:

$ celluloid --version                                                                                                                                                                                 
Celluloid 0.26

[gnome-mpv]

Only vo=libmpv is supported right now (if you try to set vo to something else, it will be overridden). We need it so that we can use the rendering API, which is the only embedding method that works on Wayland.
