HiveMind Media Player

Turn any device into a remotely controlled OVOS media player via HiveMind.

hivemind-media-player ships HiveMindPlayerProtocol, a HiveMind agent protocol plugin (hivemind.agent.protocol) that embeds ovos-media (the OCP-native media daemon) for playback and ovos-audio for TTS only, plus optional ovos-PHAL, and exposes it to any HiveMind client. Remote controllers send standard OCP (Open Voice OS Common Play) messages over the HiveMind encrypted WebSocket; the wire contract is unchanged regardless of which media backend is embedded underneath. The player device handles playback locally.

This is for devices that are not running a full OVOS instance. Think of a Raspberry Pi dedicated to being a networked speaker.

Architecture

remote controller           HiveMind (encrypted WebSocket)    this device
(Home Assistant,       <--------------------------------->    hivemind-core
 hivemind-player-ctl,                                         + HiveMindPlayerProtocol
 any OCP client)                                              + ovos-media (playback, VLC/MPV...)
                                                                + ovos-audio (TTS only)

The player agent answers no natural-language questions (natural_language_query yields only the end-of-query sentinel). Its sole role is to receive OCP bus messages forwarded by hivemind-core and play them through the embedded ovos-media daemon. Because a satellite's session is always namespaced by hivemind-core rather than left as the device-local "default" (HiveMind-Bridge-1 §4), the embedded daemon is started to act on every authorized session — this device is a single dedicated player, not a multi-session host.

Install

pip install hivemind-player-protocol

Optional extras (VLC, MPV backends):

pip install "hivemind-player-protocol[extras]"

Or from source:

git clone https://github.com/JarbasHiveMind/hivemind-media-player
cd hivemind-media-player
pip install -e .

Dependencies

The whole stack rides the ovos-bus-client 2.x line (HiveMind core 4.6.x requires it). That line, and the OVOS components updated to ride it (ovos-audio, ovos-media, ovos-plugin-manager, ovos-workshop), are currently published as prereleases.

pyproject.toml pins each dependency to its prerelease floor (for example ovos-bus-client>=2.0.0a3). A plain pip install then resolves the right versions. No --pre flag is needed. Do not add --pre. The floor pins opt into the prereleases, package by package, and keep resolution deterministic.

hivemind-core itself (AGPL) is not a runtime dependency. The plugin only imports its AgentProtocol base. The host process supplies hivemind-core. The test suite pulls it in through the [e2e] extra.

Quickstart

1. Configure hivemind-core

Edit ~/.config/hivemind-core/server.json on the player device:

{
  "agent_protocol": {
    "module": "hivemind-player-agent-plugin",
    "hivemind-player-agent-plugin": {}
  }
}

2. Configure TTS and playback

Edit ~/.config/mycroft/mycroft.conf on the same device: tts configures the embedded ovos-audio (TTS only), media configures the embedded ovos-media playback backends.

{
  "tts": {
    "module": "ovos-tts-plugin-server"
  },
  "media": {
    "preferred_audio_services": ["vlc"],
    "audio_players": {
      "vlc": {
        "module": "ovos-media-audio-plugin-vlc",
        "aliases": ["VLC"],
        "active": true
      }
    }
  }
}

See docs/configuration.md for the full reference.

3. Create a client credential

On the player device (where hivemind-core will run):

hivemind-core add-client
# note the Access Key and Password printed

4. Grant OCP permissions

# replace 3 with your Node ID from add-client
hivemind-core allow-msg "ovos.common_play.play" 3
hivemind-core allow-msg "ovos.common_play.pause" 3
hivemind-core allow-msg "ovos.common_play.resume" 3
hivemind-core allow-msg "ovos.common_play.stop" 3
hivemind-core allow-msg "ovos.common_play.next" 3
hivemind-core allow-msg "ovos.common_play.previous" 3
hivemind-core allow-msg "ovos.common_play.status" 3
hivemind-core allow-msg "speak" 3

See Permissions for the full list.

5. Set the identity on the controller

On the device that will send commands:

hivemind-client set-identity \
  --key <access_key> --password <password> \
  --host <player_device_ip> --port 5678 --siteid player

6. Start hivemind-core on the player device

hivemind-core listen

7. Control playback

python hivemind-player-ctl.py play "http://example.com/audio/track.mp3"
python hivemind-player-ctl.py pause
python hivemind-player-ctl.py resume
python hivemind-player-ctl.py next

Home Assistant / Music Assistant Integration

With hivemind-homeassistant, HiveMind player devices appear as media players in Home Assistant. Music Assistant can then browse and play music to them.

hivemind-player-ctl

hivemind-player-ctl.py is a CLI to control a running player. It requires only hivemind_bus_client and click.

Usage: python hivemind-player-ctl.py [OPTIONS] COMMAND
Options:
  --key TEXT       Access key (or read from identity file)
  --password TEXT  Password (or read from identity file)
Commands:
  play URI          Start playback of a URI
  pause             Pause
  resume            Resume
  stop              Stop
  next              Next track
  prev              Previous track
  shuffle.set       Enable shuffle
  shuffle.unset     Disable shuffle
  repeat.set        Enable repeat-all
  repeat.unset      Disable repeat
  interactive       Interactive shell

Permissions

Core audio

OCP (Open Voice OS Common Play, served by the embedded ovos-media)

Media control is ovos.common_play.* only; the legacy mycroft.audio.service.* verbs are not served by the embedded stack.

PHAL (optional)

Running the tests

The suite is end-to-end. It stands up a real hivemind-core master in-process and drives the real player plugin over a real HiveMessageBusClient (through hivescope). It asserts that remote play, pause, and stop control commands round-trip from a satellite, through the deny-by-default ACL, to the player.

The media playback backend is mocked. The embedded ovos-media daemon is disabled (disable_media=True), so no real media backend plugin loads and nothing touches an audio device or the network.

pip install -e ".[test]"   # pulls hivescope + in-process hivemind-core ([e2e])
pytest tests/

The heavyweight e2e hosts live in the [e2e] extra. [test] includes them plus the test runner. hivescope and hivemind-core are required test dependencies. The suite never importorskips them.
