Recently I got a new HiFi streamer with built-in Chromecast. When I use Plex or Plexamp to cast an album, it shows the Title, Artist and Album, but album art seems to be missing. What it looks like when casting Plex/Plexamp:
The missing piece seems to be called the ‘entity_picture’. When I create a cast stream myself in Home Assistant (Home automation tool) I can get album art shown on the screen:
When I create my own cast stream with parameters I can add an image which is displayed when casting. There’s an ‘Images’ parameter under cast metadata, see here for more info. My stream has these parameters:
Alternative solution I found today: the Symfonium app.
It connects to Plex Media Server and sends album art metadata along when casting. Unlike Plex(amp) it also supports ‘casting’ to UPnP media players which makes gapless playback possible.
Please include Artwork in the data sent through Chromecast for music playback, so that streamers with a display, such as the Wiim Ultra, can display album artwork while playing a track.
This should be an easy win for Plex and Plexamp!
