The player does not support multimedia browsing

Is it possible for the media player to have access to the media directory from the browser?

action: media_player.play_media
target:
entity_id: media_player.mqtt_media_player_lnxlink_x2media_media_player
data:
media_content_id: media-source://media_source/local/d.mp3
media_content_type: audio/mpeg
metadata: {}

I saw your thread and figured out that you were talking about my integration of MQTT Media Player. This is a custom integration, so any issues or feature requests you have, it’s best to create a new issue on my github.

I’ve pushed an update to version 2025.2.0 which will now support browsing media through the web interface of Home Assistant.
