mpd-discord-rpc's Introduction

MPD Discord RPC

Displays your currently playing song / album / artist from MPD in Discord using Rich Presence, along with the album art.

It includes support for multiple MPD hosts if, like me, you have more than one server you alternate between.

The program does not require MPD or Discord to be running in order to run.

Once installed just run mpd-discord-rpc.

Installation

Cargo

The cargo package can be found here.

cargo install mpd-discord-rpc

Arch Linux

Two AUR packages are available:

The systemd unit is included and can be started with:

systemctl --user enable --now mpd-discord-rpc

NixOS

You can use the mpd-discord-rpc package in nixpkgs. Users of home-manager can also use the services.mpd-discord-rpc.enable option.

Many thanks to Ilan Joselevich for maintaining both of those.

Configuration

Running the program once will generate a default configuration file. On Linux this will be at ~/.config/discord-rpc/config.toml

id - The Discord application ID to run through.
hosts - An array of MPD server host socket addresses. Each one will be tried in order until a playing server is found.
format - Format strings. Tokens are listed below.
- details - A format string for the top line. This is the song title by default.
- state - A format string for the second line. This is the artist / album by default.
- timestamp - The timestamp mode for the third line. This is 'elapsed' by default. Can be one of elapsed, left or off. Falls back to elapsed.
- large_image - The name of the rich presence asset that gets displayed as the large image. This is "notes" by default. Setting this to "" disables the large image.
- small_image - The name of the rich presence asset that gets displayed as the small image. This is "notes" by default. Setting this to "" disables the small image.
- large_text - A format string that is displayed upon hovering the large image. Setting this to "" disables the hover.
- small_text - A format string that is displayed upon hovering the small image. Setting this to "" disables the hover.

Formatting Tokens

Any part of the format string that does not match one of these tokens will be displayed as is. The following will automatically be replaced with their value from MPD:

$title
$album
$artist
$albumartist
$date
$track
$disc
$genre
$duration
$elapsed

Default Configuration

This configuration file is automatically generated if one does not exist. It is included here for reference.

id = 677226551607033903
hosts = ["localhost:6600"]

[format]
details = "$title"
state = "$artist / $album"
timestamp = "elapsed"
large_image = "notes"
small_image = "notes"
large_text = ""
small_text = ""

Album art

Album art is pulled from the MusicBrainz database and Album Art Archive automatically. You'll only get a cover if it can be found though; there's a couple of things you can do to help this:

Make sure your music is sensibly tagged. In most cases MusicBrainz will be searched for releases matching the album/artist name.
Add MusicBrainz release tags to your tracks. This is officially supported by MPD and can be done automatically using MusicBrainz Picard.
Add missing album art to MusicBrainz. Many albums are missing covers, and you can upload your own to the database to contribute these for everyone.

mpd-discord-rpc's Issues

Can't connect to socket file

I run mpd using a socket file (bind_to_address "~/.mpd/socket" in the mpd config file). This works fine for most applications, like Cantata, ncmpc, mpdris2, etc.

However, mpd-discord-rpc fails to connect. Here's my config file:

id = 677226551607033903
hosts = ["/home/username/.mpd/socket"]

[format]
details = "$title"
state = "$artist - $album"

I modified the try_get_mpd_conn function to print the error from MPDClient::connect instead of discarding it, and got this:

failed to lookup address information: Name or service not known

Updates to discord stop if you skip songs too quickly

Hi,

I'm not sure how else to describe it but from my current usage, I have a hotkey setup to skip a song if I don't want to listen to it and go to the next in the playlist, and the currently playing song automatically appears in the top status bar of my screen. If I use that hotkey without giving the song a chance to play for maybe 5-10 seconds or so, I'm basically rolling a dice on whether discord will stop getting updates or not, and when I lose the dice roll, the music stays stuck on whatever song it was on when it broke, which creates a weird case where sometimes I learn way later that according to discord I've been listening to this one song for like 3 days or something. Hopefully it can be reproduced and fixed, it's not really a major bug but it is annoying to have to run systemctl --user restart mpd-discord-rpc every time it does this or to be forced to let a song that I don't want to hear play at that point in time.

Pkg info below, not sure about how to give system info or if that'd even help.

Use the merge crate

Use the merge crate instead of Config.merge() and Format.merge().
This would simplify the code and make adding new options easier by introducing a new dependency.
I could implement this if i get the green light.

Question how to set the image

so reading through the readme file i cant find anything related to changing the image that shown in the discord other than removing it. so how does it work? is it harcoded to only show it or hide it or you can set it to whatever you want? what i wanted is to use from the music file it self(file thumbnail or something not sure what it called) but not sure how.

it will be nice if theres some other description relate to it in the documentation.

[feature request] option to clear the status if paused

i believe adding an configuration option to completely clear the "playing" status if mpd is paused should be added especially since i always have it running in the background, but if i'm not actually listening to anything, it still shows up as my playing status listening to the song it's paused on.

[unless this is already the default behavior and there's something going on in my end of this.]

AUR PKGBUILD: systemd service installs as `mpc-discord-rpc.service` instead of `mpd-discord-rpc.service`

Thought I was going insane trying to enable the package.

-install -Dm 644 "$srcdir/mpd-discord-rpc/mpd-discord-rpc.service" "$pkgdir/usr/lib/systemd/user/mpc-discord-rpc.service"
+install -Dm 644 "$srcdir/mpd-discord-rpc/mpd-discord-rpc.service" "$pkgdir/usr/lib/systemd/user/mpd-discord-rpc.service"

Can crash if MPD connection lost mid-fetch

I've tried both cargo and AUR package using defaults. I'm using the regular discord package of Arch Linux.

Specify target-dir in AUR PKGBUILD

When using a global target-dir, the package step of the PKGBUILD fails:

==> Starting package()...
install: cannot stat '/home/serial/.cache/paru/clone/mpd-discord-rpc/src/mpd-discord-rpc/target/release/mpd-discord-rpc': No such file or directory
==> ERROR: A failure occurred in package().
    Aborting...

error: packages failed to build: mpd-discord-rpc-v1.6.0.r0.ee29533-1 (mpd-discord-rpc-git)

The fix is to just specify the target-dir:

 build() {
     cd "$srcdir/mpd-discord-rpc"
-    cargo build --release --locked
+    cargo build --release --locked --target-dir target
 }

RPC library error: channel to be open full(..)

This package was working fine - it's pretty cool, thanks! - until very recently, where it just... stopped. Not sure if it's a discord update, or something else.

systemctl --user status mpd-discord-rpc output:

Feb 02 17:44:48 hearth mpd-discord-rpc[1552]: 2024-02-02T17:44:48.035347Z ERROR mpd_discord_rpc: {"error_message":"Io Error","error_type":"RPCLibraryError>

On Arch linux 6.7.3-arch1-1, using Discord Stable 263172 (f95e991), not sure if any additional RPC package is relevant given none are listed as dependencies, but libtirpc is 1.3.4-1, just in case.

Not sure how to troubleshoot, to be honest. Running mpd-discord-rpc with the systemctl process stopped says that it connects to discord fine:

024-02-02T17:55:56.960104Z  INFO connect: mpd_protocol::connection: connected successfully version="0.23.5"
2024-02-02T17:55:56.960129Z  INFO mpd_utils::persistent_client: Connected to 'localhost:6600'
2024-02-02T17:55:57.464823Z  INFO mpd_discord_rpc: Connected to Discord

And my firewall should be set up so as to allow discord to connect.

Restarting the systemctl process after killing both that from before and then killing the one ran in the terminal yields this systemctl output:

Feb 02 18:00:17 hearth systemd[1465]: Started Discord Rich Presence for MPD.
Feb 02 18:00:17 hearth mpd-discord-rpc[247950]: 2024-02-02T18:00:17.014233Z  INFO connect: mpd_protocol::connection: connected successfully version="0.23.>

But still no cigar in the discord client.

Here is my config.toml:

id = 677226551605023604
hosts = ["localhost:6600"]

[format]
details = "$title"
state = "$artist / $album"
timestamp = "elapsed"
large_image = "notes"
small_image = ""
large_text = ""
small_text = ""

Any advice on troubleshooting is gratefully received, and thank you for making a neat app!

I'm getting this when building, both when trying to install from the AUR and by cloning the repo and running cargo install manually. I have no rust knowledge and that issue mentioned at the end of the error log is pretty much greek to me.

Apparently it's something with mpd_client so I opened an issue there too

Update NixOS package to latest version

@Kranzes could you update the Nix package to v1.5.1 please?

Is this normal? There is no other stdout info

Also the AUR package doesn't seem to build properly.

elapsed time does not update

so apparently the elapsed time on discord updates every 2 seconds for the person thats running mpd-discord-rpc, but it does not update for the other person that is just viewing the other person's discord status/profile.
it only updates once every minute or so, it inst consistent at all.
i would like if you could make so it updates the elapsed time every 1 second for both of the users, the one that is running mpd-discord-rpc and the one that is viewing the other person's profile.

Nothing happens in Discord when running the program

I'm probably the one at fault here, but I cannot get this or any other RPC integration to work. I have tried it with both discord and discord-canary from the AUR. I am using the default configuration.

Output:

Entering idle mode
Exiting idle mode
Entering idle mode
Exiting idle mode

The mode switches when I play/pause mpd, as expected.

Am I missing some setup in Discord? I couldn't find any installation instructions in the readme other than to run the program.

InvalidMessage when playing a song

Hi, I installed this with cargo, and when I run it it seems to work fine until I play a song, I get a InvalidMessage error:

I'm on macOS Monterey if it's any help. Let me know if you need any extra info.

Crashes if connection to Discord is lost

If Discord restarts or the connection to its RPC server drops for whatever reason, the program crashes.

Internet Radio usually doesn't have any info about $duration of the song. I think album cover will not work too, because MPD doesn't provide any information about $album or $artist (at least i don't see them in ncmpcpp) and $title in MPD consist of two parts: $artist-$title provided by Internet Radio

Default fallback if missing from config

It would be nice if the program would fallback to the default options if they aren't defined in the config.toml.

For example, a config.toml with this content:

[format]
large_image = ""

Should still work, and not crash the program. The program will then use the default options but replace the large_image option with the one defined in the config file.

[new-feature-request] Adding rich presence buttons

It would be nice if there are rich presence buttons that shows link for what song you are playing on spotify or/and youtube

Better error handling

Following on from the more flexible config changes in #19, I'd like to see some nicer error handling. Most unwraps should be replaced with either an expect to print a slightly more sensible message, or friendly console output and a clean exit so it's clear what's wrong with the config.

[feature] config option for string formatting

Add a configuration option to change the string display format for both the details (song title) and state (artist / album) to allow for custom formatting.

For example the current default config options might look like:

[format]
details = "$title"
state = "$artist / $album"

@Phate6660 I spotted your fork, thank you for the inspiration for this and the kind words. I'm glad you like it :)

Using release-group id instead of release id to fetch album arts

I was investigating why this would not show album art for some of my albums.

This API call finds the release with the ID b56f3ba4-77c8-36c4-95f6-4b7da3d21e9a
https://musicbrainz.org/ws/2/release/?query=artist:Muse%20AND%20release:Origin%20of%20Symmetry&limit=1&fmt=json
We can confirm from the following url that no cover art exists for this.
https://coverartarchive.org/release/b56f3ba4-77c8-36c4-95f6-4b7da3d21e9a/front-250

There are 26 releases within the release-group of this album. Only 5 of them lack an attached album cover art. It seems to be hit or miss.
However, release groups themselves get album arts, and we can fetch them using this url, almost the same as it is done currently.
https://coverartarchive.org/release-group/{}/front-250

We can follow the same API result to get the release-group id. It's ef03fe86-b54c-3667-8768-029833e7e1cd. We can see that the following indeed does return a valid cover art.
https://coverartarchive.org/release-group/ef03fe86-b54c-3667-8768-029833e7e1cd/front-250

I found forgoing releases and going for the release-groups a more reliable way to get the album arts (at least for the artists I listen to), however I did not test this thoroughly. Alternatively, it could become a fallback if there is no cover for the release. This would require an extra request with the client.

Album art not always showing up depending on the song

So first of all, I love the new update. I was planning on trying to learn Rust and add the feature myself, but looks like someone read my mind. It's great, but I've noticed that some songs won't have their album art displayed.

Here are images showing just one example of it:

You can see that the album art is not displayed next to the RPC itself.

Yet dunst is able to pickup the album art just fine here.

This isn't the only song where this happens. This might be because of the method that's being used to get the album art. The album art that is being pickup is included in the song file itself, but if mpd-discord-rpc is using some third-party to fetch album art, then that might be why it's not picking up the album art. I'm not sure if it is possible, but the program could try fetching the album art from the file itself assuming it's not already trying to do that. I'm not educated on the matter, but I'm sure you will be able to enlighten the idea further.

Edit: It seems to be a 50:50 for me as far as which songs have their album art shown.

feature request: album cover

It would be great if there was an option to have it fetch the appropriate album cover image from the internet and show it in the image box. Many Discord RPCs for music already do that.

Not connecting to Discord anymore.

Oddly enough, there are no errors or anything. It runs just like it usually does.

However, there is simply just no rich presence being displayed.

I'm not sure what the issue could be, as my own plus other rich presence programs work fine.

Though it did stop working after Discord updated, so that could be part of the issue.

Customization

Is there any built in way to modify the value of the game being played from 'music', in addition, is there any way to change the image?
