I'd assume quality is for audio quality, I tried uncommenting it, still no results.

When I uncomment the line #max_height = "720" # Optional maximal height of video, example: 720, 1080, 1440, 2160, ...

The container fails to start: fatal msg="failed to load configuration file" error="failed to unmarshal toml: line 31: (config.Feed.MaxHeight) cannot unmarshal TOML string into int"
