I am really into this tool, and I am really really appreciate your contribution. But, please help me to get it to work. External mpv (installed from SVP manager), and SVP

"mpv_ext_ipc": mpvpipe,               * tried typed in 'null', still not working

needs quotes around the mpvpipe like "mpvpipe". You may also need to use a downloaded copy of MPV following the directions here, as I am not sure if the SVP MPV is new enough: https://github.com/iwalton3/plex-mpv-shim#svp-integration-1
