There is no built in way to cast plex music to DLNA speakers. This project will be the bridge.
- Use UPNP auto discovery to find your DLNA devices in LAN.
- Use Plex GDM to notify Plex clients about the DLNA devices.
- Connect your DLNA device to plex.tv and let the Plex clients which don't support GDM find your DLNA devices. eg, Plexamp.
- Connect to your DLNA speakers with your Plex client's
Select Playerwindow.
Just clone this repo and run main.py with python.
It's tested with python 3.9.
git clone https://github.com/songchenwen/plexdlnaplayer.git
cd plexdlnaplayer
python3 main.py
It's recommended to use this project in docker.
Note: It can only run with host network mode, due to udp broadcasting by UPNP and Plex GDM discovery.
docker run -d \
--name=plexdlnaplayer \
--network host \
--restart unless-stopped \
-v <path to data>:/config
ghcr.io/songchenwen/plexdlnaplayer
This project is configured with pydantic settings.
| Env | Description | Default |
|---|---|---|
| HTTP_PORT | The port for the http server | 32488 |
| HOST_IP | IP of this host. Plex client will use http://HOST_IP:HTTP_PORT to connect to your DLNA devices |
Auto Guess |
| ALIASES | Preferred DLNA device names, looks like this uuid:name1,ip:name2,origin_name:name3 |
Empty |
| LOCATION_URL | The location url of your DLNA device. Setting this env will disable DLNA device auto discovery | None |
| CONFIG_PATH | In where to store the persistent data. | /config |
Normally, you don't need to configure any of these environment variables.
If you need data persistence with docker, you need to map /config to some location in your host. Data persistence will only be needed if you use the following features.
- Use Plexamp as controller instead of Plex.
- Edit device alias in the web page, instead of using environment variables.
Go to http://HOST_IP:HTTP_PORT to manage your DLNA devices.
In this page you can link your DLNA devices to your plex.tv account and edit the display name of them.
Because Plexamp don't support GDM discovery. You need to link your device to your account to use Plexamp as the controller.
Yeah, I know, Plexamp has the better play queue support.
Any discovery of a new compatible DLNA device will start a new thread looping for its status.
Plex client uses the new subscribing method to get the player's status, while Plexamp uses the old inefficient polling way. In this case, using Plexamp with this project will certainly consume more resources.
DLNA devices can vary in functions. These differences will affect us most on the auto next part, which is where one track ends and we auto start playing the next track. If you find your device is unable to auto start the next track, please try to edit the check_auto_next function in plex/adapters.py. Pull request is always welcome.
- A virtual device to play music with all the available DLNA speakers in sync.
