Comment:
well, probably just a repeated typo here but I get an error in mpv log if I set `gpu_context=`: the correct option name is `gpu-context=` whit a _hyphen_  instead of a _underscore_

```
Error parsing option gpu_context (option not found)
/home/user/.config/mpv/mpv.conf:24: setting option gpu_context='auto' failed.

```
