Several M3U playlist players are available on the official LG Content Store (webOS). Here is an overview of ELK Player alongside other documented options, based on publicly available information at time of writing. None of these apps provide playlists or media content — all require you to supply your own compatible playlist source.
M3U playlist URL support, added by MAC address via the website. Lightweight, single-purpose player.
M3U, Xtream Codes API and MAC+URL support, with a playlist manager, themes and parental controls.
M3U and Xtream Codes support, EPG, multi-screen viewing and Chromecast/AirPlay.
Playlist via URL, login or file upload, with resume playback and category locking.
