# How to Modify the MPV Player

Be sure to close the Plex App before applying the modifications.

  • Go to https://sourceforge.net/projects/mpv-player-windows/files/libmpv/
    • Click the modified column to sort by newest.
    • Download mpv-dev-x86_64-v3-{date}-git-{hash}.7z, where date is the most recent date in YYYYMMDD format and hash is some random hash.
  • Extract the zip to somewhere, and copy the libmpv-2.dll file.
  • Go to plex install location (by default C:\Program Files\Plex\Plex, though it can vary).
    • If inside the Plex folder libmpv-2.dll exists paste the copied libmpv-2.dll and overwrite it. If it doesn't paste it and rename it to mpv-2.dll. It should be ~80MB in constrast to the original's 10MB.
  • Go to %localappdata%\plex (by default C:\Users\YourUserName\AppData\Local\Plex, where YourUserName is your account name. Again, it can vary).
    • Create mpv.conf file
    • Paste this into the file:
profile=gpu-hq
vo=gpu-next
tls-ca-file={Plex}\resources\cacert.pem

where {Plex} is your plex install path, so it'll most likely look something like tls-ca-file=C:\Program Files\Plex\Plex\resources\cacert.pem if you never changed it.

C:\Users\YourUserName\AppData\Local\Plex is the root folder of the MPV config so you can put your own MPV config in there, do note that Plex overwrites most keybinds tho. For more details on MPV configs visit the tutorial.
