Media keys (mpris) support

[ilya-zlobintsev]

I'm not sure if this is the case on Windows, but on Linux there's no media keys support. I'm not sure if this has to be done in the web wrapper or implemented manually, but there's a dbus interface for media key control.

It's definitely possible but this is possibility a very substantial addition. There is an input manager for handling remote control of other types (not sure about mpris) that I haven't done anything with yet.

There's an mpris plugin for mpv, but I don't know if it works with libmpv (which is used here if I understand it correctly?) without the full player.

[iwalton3]

It does work in MPV Shim but this player doesn't respond to MPV keybinds or player events. It is more treated like an embedded player.

I've made this small script to play/pause:

import requests
import os
from os.path import expanduser

home = expanduser("~")

TOKEN = "1234567890abcdefgh"
SERVER_URL = "https://jellyfin.example.com"

headers = {
        "X-Emby-Authorization": """MediaBrowser Client="Python", Device="script", DeviceId="asdf", Version="0.1", Token=\"""" + TOKEN + "\"" }

try:
    f = open(home + "/.cache/jellyfin-id")
    session_id = f.read()
except:
    sessions = requests.get(SERVER_URL + "/Sessions?ActiveWithinSeconds=960", headers=headers).json()
    
    for session in sessions:
        if session["DeviceName"] == "Web Browser":
            session_id = session["Id"]

            f = open(home + "/.cache/jellyfin-id", "w")
            f.write(session_id)
            
            break

requests.post(SERVER_URL + "/Sessions/" + session_id + "/Playing/PlayPause", headers=headers)

If you install this and softlink mpris.so to /usr/share/mpv/scripts/mpris.so in ~/.local/share/jellyfinmediaplayer/scripts, play/pause and metadata works perfectly, both for music and video.

[ilya-zlobintsev]

Thank you, that works perfectly, though the path was /usr/lib/mpv/mpris.so for me.

[ilya-zlobintsev]

Would it be possible to include the plugin by default with it being MIT licensed?

[rodrigosargaco]

Is it possible to add play/pause with spacebar key? (Windows 10)

[iwalton3]

There is partial media key support on Linux in the new release. It just binds to the keyboard keys and doesn't do any MPRIS stuff. This may or may not work in Flatpak.

[iwalton3]

For MPRIS it looks like combining https://packages.debian.org/buster/libmpris-qt5-1 and the taskbar component added recently is a solid option.

Linking/copying mpris.so to the Jellyfin media player scripts directory worked for me. The only slight annoyance is that title information is not shown. The mpris notification only shows the streaming URL that is being used.

[zjeffer]

Linking the mpris.so file indeed works, here's a handy command to link the file:

ln -s /usr/lib/mpv/mpris.so ~/.local/share/jellyfinmediaplayer/scripts

It has full MPRIS support, except for the information. Has anyone found a fix for that yet?

[viggy96]

@zjeffer I started on a fix for missing title data but as I talked to the other developers, I realised there are other issues with this hacky solution to MPRIS.

The problem is that since this is being applied from the MPV side, the next/previous track buttons don't work, because MPV doesn't know what the next/previous items are. MPRIS needs to be implemented at a deeper level in JMP.

That said, if you just want play/pause functionality, then just copy/link the mpris.so file and you're good for now.
