There's quite a few apps that support it, but like books, it's not the main dev focus. Personally, I have a collection of about 8k 'albums' (including singles) that took like a whole day for Jellyfin to scan and index properly. Then navigating through it was always very slow. I leave video content to Jellyfin and use Navidrome for music because it's significantly faster and most apps that support Jellyfin also support Navidrome/Subsonic, etc.
