Home Assistant Emby Media Player Entity

Overview

Implement MediaPlayerEntity following HA patterns with Emby API mappings.

This covers supported features, state machine, properties, async methods, and Emby-specific implementation details.

Entity Structure

"""Emby media player entity."""
from __future__ import annotations

from homeassistant.components.media_player import (
    BrowseMedia,
    MediaPlayerEntity,
    MediaPlayerEntityFeature,
    MediaPlayerState,
    MediaType,
)

from .coordinator import EmbyDataUpdateCoordinator

    ) -> None:
        """Initialize the media player."""
        super().__init__(coordinator, session.device_id)

Supported Features

Map Emby capabilities to HA features:

HA Feature	Emby API	Notes
PLAY	PlayState/Unpause	Resume playback
PAUSE	PlayState/Pause	Pause playback
STOP	PlayState/Stop	Stop playback
SEEK	PlayState/Seek	PositionTicks
VOLUME_SET	SetVolume	0-100 scale
VOLUME_MUTE	ToggleMute	Boolean toggle
NEXT_TRACK	PlayState/NextTrack	Next in queue
PREVIOUS_TRACK	PlayState/PreviousTrack	Previous in queue
PLAY_MEDIA	Play items	By item ID
BROWSE_MEDIA	Items endpoint	Library browsing

State Machine

@property
def state(self) -> MediaPlayerState | None:
    """Return current state."""
    session = self._get_session()
    if session is None:
        return MediaPlayerState.OFF

    if session.now_playing is None:
        return MediaPlayerState.IDLE

    if session.play_state.is_paused:
        return MediaPlayerState.PAUSED

    return MediaPlayerState.PLAYING

State mapping:

• No session → OFF
• Session but nothing playing → IDLE
• Playing and paused → PAUSED
• Playing and not paused → PLAYING
• Buffering (if detectable) → BUFFERING

Media Browsing

        children=children,
    )

Type Mapping Helpers

def _map_media_type(self, emby_type: str) -> MediaType:
    """Map Emby media type to HA MediaType."""
    mapping: dict[str, MediaType] = {
        "Movie": MediaType.MOVIE,
        "Episode": MediaType.TVSHOW,
        "Audio": MediaType.MUSIC,
        "MusicVideo": MediaType.VIDEO,
        "Video": MediaType.VIDEO,
        "Photo": MediaType.IMAGE,
    }
    return mapping.get(emby_type, MediaType.VIDEO)

def _map_media_class(self, emby_type: str) -> MediaClass:
    """Map Emby type to HA MediaClass."""
    mapping: dict[str, MediaClass] = {
        "Movie": MediaClass.MOVIE,
        "Series": MediaClass.TV_SHOW,
        "Season": MediaClass.SEASON,
        "Episode": MediaClass.EPISODE,
        "Audio": MediaClass.TRACK,
        "MusicAlbum": MediaClass.ALBUM,
        "MusicArtist": MediaClass.ARTIST,
        "Playlist": MediaClass.PLAYLIST,
        "CollectionFolder": MediaClass.DIRECTORY,
    }
    return mapping.get(emby_type, MediaClass.DIRECTORY)

Emby Tick Conversions

Emby uses "ticks" (100-nanosecond intervals):

TICKS_PER_SECOND = 10_000_000
TICKS_PER_MS = 10_000

def ticks_to_seconds(ticks: int) -> int:
    """Convert Emby ticks to seconds."""
    return ticks // TICKS_PER_SECOND

def seconds_to_ticks(seconds: float) -> int:
    """Convert seconds to Emby ticks."""
    return int(seconds * TICKS_PER_SECOND)

def ticks_to_timedelta(ticks: int) -> timedelta:
    """Convert Emby ticks to timedelta."""
    return timedelta(microseconds=ticks // 10)

Image URL Building

def _build_image_url(
    self,
    item_id: str,
    image_type: str = "Primary",
    max_width: int = 500,
) -> str:
    """Build URL for Emby item image."""
    return (
        f"{self.coordinator.client.base_url}"
        f"/Items/{item_id}/Images/{image_type}"
        f"?maxWidth={max_width}"
        f"&api_key={self.coordinator.client.api_key}"
    )

Security note: Don't expose image URLs to media_image_url without auth context. Set media_image_remotely_accessible = False and let HA proxy the images.

Platform Setup

"""Platform setup for Emby media player."""
from homeassistant.config_entries import ConfigEntry
from homeassistant.core import HomeAssistant
from homeassistant.helpers.entity_platform import AddEntitiesCallback

from . import EmbyConfigEntry
from .media_player import EmbyMediaPlayer


async def async_setup_entry(
    hass: HomeAssistant,
    entry: EmbyConfigEntry,
    async_add_entities: AddEntitiesCallback,
) -> None:
    """Set up Emby media player entities."""
    coordinator = entry.runtime_data

    entities = [
        EmbyMediaPlayer(coordinator, session)
        for session in coordinator.data.sessions.values()
        if session.supports_media_control
    ]

    async_add_entities(entities)

The Bottom Line

Properties return cached data. Async methods do I/O. Map Emby concepts to HA correctly.

• Use coordinator data for all state
• Convert ticks to seconds for HA
• Implement browse_media for library access
• Never block in properties
