Hi there!
I’m currently working on the Companion Media Player HACS Addon which adds a media player for the media sessions of Android Devices which have the Home Assistant companion app installed.
Everything is working fine so far. Seeking works, see what is playing and even controlling the volume (since 2026.3.2 supports also min/max volume).
Now one big thing is missing: The cover images (album art). Many media sessions in Android does not have publicly accessible URLs for their cover images. For example, if you use local media Players (like VLC). And even not all cover images of Spotify are publicly accessible. Therefore, I would like to add a functionality to upload cover images to Home Assistant and make them available via the MediaPlayer (e.g. media_image_url).
The meaningful settings will be JPEG in 1000x1000 pixels (current recommend standard for cover images).
Any ideas what might be the best existing API in Home Assistant or what changes needs to be done to make this possible?
Cheers,
Gregor
