Media Player Entity Media Player

:::info Incomplete This entry is incomplete. Contribution welcome. ::: A media player entity controls a media player. Derive a platform entity from homeassistant.components.media_player.MediaPlayerEntity.

Properties

:::tip Properties should always only return information from memory and not do I/O (like network requests). Implement update() or async_update() to fetch data. :::

Name Type Default Description
supported_features int int Flag supported features.
sound_mode string None The current sound mode of the media player
sound_mode_list list None Dynamic list of available sound modes (set by platform, empty means sound mode not supported)
source string None The currently selected input source for the media player.
source_list list None The list of possible input sources for the media player. (This list should contain human readable names, suitable for frontend display)
media_image_url string None URL that represents the current image.
media_image_remotely_accessible boolean False Return True if property media_image_url is accessible outside of the home network.
device_class string None Type of media player.
group_members list None A dynamic list of player entities which are currently grouped together for synchronous playback. If the platform has a concept of defining a group leader, the leader should be the first element in that list.

Supported Features

Supported features are defined by using values in the MediaPlayerEntityFeature enum and are combined using the bitwise or (|) operator.

Value Description
BROWSE_MEDIA Entity allows browsing media.
CLEAR_PLAYLIST Entity allows clearing the active playlist.
GROUPING Entity can be grouped with other players for synchronous playback.
MEDIA_ANNOUNCE Entity supports the play_media service's announce parameter.
MEDIA_ENQUEUE Entity supports the play_media service's enqueue parameter.
NEXT_TRACK Entity allows skipping to the next media track.
PAUSE Entity allows pausing the playback of media.
PLAY Entity allows playing/resuming playback of media.
PLAY_MEDIA Entity allows playing media sources.
PREVIOUS_TRACK Entity allows returning back to a previous media track.
REPEAT_SET Entity allows setting repeat.
SEEK Entity allows seeking position during playback of media.
SELECT_SOUND_MODE Entity allows selecting a sound mode.
SELECT_SOURCE Entity allows selecting a source/input.
SHUFFLE_SET Entity allows shuffling the active playlist.
STOP Entity allows stopping the playback of media.
TURN_OFF Entity is able to be turned off.
TURN_ON Entity is able to be turned on.
VOLUME_MUTE Entity volume can be muted.
VOLUME_SET Entity volume can be set to specific levels.
VOLUME_STEP Entity volume can be adjusted up and down.

States

The state of a media player is defined by using values in the MediaPlayerState enum, and can take the following possible values.

Value Description
OFF Entity is turned off and is not accepting commands until turned on.
ON Entity is turned on, but no details on its state is currently known.
IDLE Entity is turned on and accepting commands, but currently not playing any media. Possibly at some idle home screen.
PLAYING Entity is currently playing media.
PAUSED Entity has an active media and is currently paused
STANDBY Entity is in a low power state, accepting commands.
BUFFERING Entity is preparing to start playback of some media

Methods

Play Media

Tells the media player to play media. Implement it using the following:

class MyMediaPlayer(MediaPlayerEntity):

    def play_media(
        self,
        media_type: str,
        media_id: str,
        enqueue: MediaPlayerEnqueue | None = None,
        announce: bool | None = None, **kwargs: Any
    ) -> None:
        """Play a piece of media."""

    async def async_play_media(
        self,
        media_type: str,
        media_id: str,
        enqueue: MediaPlayerEnqueue | None = None,
        announce: bool | None = None, **kwargs: Any
    ) -> None:
        """Play a piece of media."""

The enqueue attribute is a string enum MediaPlayerEnqueue:

  • add: add given media item to end of the queue
  • next: play the given media item next, keep queue
  • play: play the given media item now, keep queue
  • replace: play the given media item now, clear queue

When the announce boolean attribute is set to true, the media player should try to pause the current music, announce the media to the user and then resume the music.

Browse Media

If the media player supports browsing media, it should implement the following method:

class MyMediaPlayer(MediaPlayerEntity):

    async def async_browse_media(
        self, media_content_type: str | None = None, media_content_id: str | None = None
    ) -> BrowseMedia:
        """Implement the websocket media browsing helper."""
        return await media_source.async_browse_media(
            self.hass,
            media_content_id,
            content_filter=lambda item: item.media_content_type.startswith("audio/"),
        )

If the media player also allows playing media from URLs, you can also add support for browsing Home Assistant media sources. These sources can be provided by any integration. Examples provide text-to-speech and local media.

from homeassistant.components import media_source
from homeassistant.components.media_player.browse_media import (
    async_process_play_media_url,
)

class MyMediaPlayer(MediaPlayerEntity):

    async def async_browse_media(
        self, media_content_type: str | None = None, media_content_id: str | None = None
    ) -> BrowseMedia:
        """Implement the websocket media browsing helper."""
        # If your media player has no own media sources to browse, route all browse commands
        # to the media source integration.
        return await media_source.async_browse_media(
            self.hass,
            media_content_id,
            # This allows filtering content. In this case it will only show audio sources.
            content_filter=lambda item: item.media_content_type.startswith("audio/"),
        )

    async def async_play_media(
        self,
        media_type: str,
        media_id: str,
        enqueue: MediaPlayerEnqueue | None = None,
        announce: bool | None = None, **kwargs: Any
    ) -> None:
        """Play a piece of media."""
        if media_source.is_media_source_id(media_id):
            media_type = MediaType.MUSIC
            play_item = await media_source.async_resolve_media(self.hass, media_id, self.entity_id)
            # play_item returns a relative URL if it has to be resolved on the Home Assistant host
            # This call will turn it into a full URL
            media_id = async_process_play_media_url(self.hass, play_item.url)

        # Replace this with calling your media player play media function.
        await self._media_player.play_url(media_id)

Select sound mode

Optional. Switch the sound mode of the media player.

class MyMediaPlayer(MediaPlayerEntity):
    # Implement one of these methods.

    def select_sound_mode(self, sound_mode):
        """Switch the sound mode of the entity."""

    def async_select_sound_mode(self, sound_mode):
        """Switch the sound mode of the entity."""

Select source

Optional. Switch the selected input source for the media player.

class MyMediaPlayer(MediaPlayerEntity):
    # Implement one of these methods.

    def select_source(self, source):
        """Select input source."""

    def async_select_source(self, source):
        """Select input source."""

Mediatype

Required. Returns one of the values from the MediaType enum that matches the mediatype

CONST
MediaType.MUSIC
MediaType.TVSHOW
MediaType.MOVIE
MediaType.VIDEO
MediaType.EPISODE
MediaType.CHANNEL
MediaType.PLAYLIST
MediaType.IMAGE
MediaType.URL
MediaType.GAME
MediaType.APP
class MyMediaPlayer(MediaPlayerEntity):
    # Implement the following method.

    @property
    def media_content_type(self):
    """Content type of current playing media."""

:::info Using the integration name as the media_content_type is also acceptable within the play_media service if the integration provides handling which does not map to the defined constants. :::

Available device classes

Optional. What type of media device is this. It will possibly map to google device types.

Value Description
tv Device is a television type device.
speaker Device is speakers or stereo type device.
receiver Device is audio video receiver type device taking audio and outputting to speakers and video to some display.

Proxy album art for media browser

Optional. If your media player is only accessible from the internal network, it will need to proxy the album art via Home Assistant to be able to work while away from home or through a mobile app.

To proxy an image via Home Assistant, set the thumbnail property of a BrowseMedia item to a url generated by the self.get_browse_image_url(media_content_type, media_content_id, media_image_id=None) method. The browser will then fetch this url, which will result in a call to async_get_browse_image(media_content_type, media_content_id, media_image_id=None).

:::info Only use a proxy for the thumbnail if the web request originated from outside the network. You can test this with is_local_request(hass) imported from homeassistant.helpers.network. :::

In async_get_browse_image, use self._async_fetch_image(url) to fetch the image from the local network. Do not use self._async_fetch_image_from_cache(url) which should only be used to for the currently playing artwork.

:::info Do not pass an url as media_image_id. This can allow an attacker to fetch any data from the local network. :::

class MyMediaPlayer(MediaPlayerEntity):

    # Implement the following method.
    async def async_get_browse_image(self, media_content_type, media_content_id, media_image_id=None):
    """Serve album art. Returns (content, content_type)."""
    image_url = ...
    return await self._async_fetch_image(image_url)

Grouping player entities together

Optional. If your player has support for grouping player entities together for synchronous playback (indicated by SUPPORT_GROUPING) one join and one unjoin method needs to be defined.

class MyMediaPlayer(MediaPlayerEntity):
    # Implement one of these join methods:

    def join_players(self, group_members):
        """Join `group_members` as a player group with the current player."""

    async def async_join_players(self, group_members):
        """Join `group_members` as a player group with the current player."""

    # Implement one of these unjoin methods:

    def unjoin_player(self):
        """Remove this player from any group."""

    async def async_unjoin_player(self):
        """Remove this player from any group."""
