Cover Art possibility?

[aiftikhar]

I wanted to know if it was possible to add the cover art/ album art? I have been able to integrate this pretty well into my home assistant setup, but it would be awesome to be able to get the cover art too, just to make the card feel more complete. I try to see if there was any way possible, but it seems I would need a video id, since the title and duration is not enough to pull the video thumbnail from YouTube.

Based on my limited knowledge and some web search it seems like its possible and published to URI, so whenever its available ie for YouTube to just publish it.

The MediaSession can expose an "album art" Uri, however that URI is a local Android URI, meaning that you can't share it through MQTT, you can only use it to download the image file locally.
It can also expose a bitmap directly, in a small (thumbnail) format.
It could technically be possible to load the bitmap, compress it to PNG then send it as an MQTT message but it seems a bit overkill.

I did a few tests with the Youtube Android app and it doesn't share any image, only: artist, album artist, album, title, duration, video width and height.
The Youtube Music app however, shares the album art as a small bitmap.
