REVIEW
Flux Player is the codec-omnivore LG's built-in media player isn't.
Flux Digital's free webOS app handles DLNA/UPnP browsing, M3U IPTV playlists, and the codec edge cases LG's stock player chokes on, with a no-frills interface that gets out of the way.

Flux Player exists because LG’s built-in media player keeps refusing to play the file you actually want to watch. That is the entire pitch, and on a smart-TV platform where polished general-purpose video players are scarce and the alternatives are either Plex’s full server-and-client stack or one of the dozen near-identical IPTV apps in the Content Store, it is a more useful pitch than it sounds. Flux Digital’s app is free, handles DLNA and UPnP servers without configuration, ingests M3U playlists for IPTV, and chews through the codec and container edge cases that the stock player chokes on.
What it isn’t is pretty. The interface was designed for directional-pad navigation first and Magic Remote second, the visual design is a generation behind the platform norm, and updates land months after the developer ships them on Android or Fire TV. None of those things matter much if the problem you are solving is that an MKV with a DTS audio track will not play on your LG OLED — and that is the problem most people install Flux Player to solve.
For LG TV owners running a NAS-based home library, this is the right install. For households that want a unified interface across devices, Plex remains the better pick, and the comparison is not close. Flux Player is a tool, not a service. The free price, the format tolerance, and the absence of an account requirement are what make the rough edges easy to forgive.

FEATURES
Flux Player is a free general-purpose media player for LG webOS, built by Flux Digital GmbH and aimed squarely at the gap between the TV's built-in DLNA browser and a full Plex / Emby setup. It plays local files from USB, streams from DLNA / UPnP servers on the network, and ingests M3U / M3U8 playlists for IPTV — three jobs, one app, no account required.
Format coverage is the headline. MKV with multiple audio tracks, MP4 / H.264 and H.265, AVI, MOV, WMV, FLV, plus the external subtitle formats (SRT, SUB, SSA) that webOS's stock player handles inconsistently. Hardware decoding is wired through to the underlying webOS pipeline, so 1080p and most 4K HEVC content plays without stutter on mid-range LG sets from the past five years.
IPTV mode accepts user-supplied M3U URLs or files, groups channels by category, and remembers favourites. There is no built-in catalogue and no bundled streams — the user brings the playlist, which is both the point and the friction. DLNA browsing surfaces folders, thumbnails, and metadata from any standard server (Plex's DLNA endpoint, Jellyfin, Synology DiskStation, MiniDLNA) without configuration.
MISSION ACCOMPLISHED
The format tolerance is real and it solves the actual problem. LG's built-in media player refuses about a third of the MKVs and TS files in a typical home library — wrong audio codec, missing subtitle support, container quirks. Flux Player chews through most of them, and the cases it can't handle fail cleanly rather than freezing the TV.
Pricing is the other genuine win. The app is free, ad-light by smart-TV standards, and doesn't gate the IPTV or DLNA features behind a subscription the way several competing webOS players do. For a household running a NAS-based media library, this is the cheapest path to a working TV-side client.
ROOM TO IMPROVE
The interface is functional rather than polished. Magic Remote pointing works but the layout was clearly designed for directional-pad navigation first, with small hit-targets, dense text, and modal dialogs that dismiss awkwardly. The visual design lags both the LG content-store norm and competing players like Plex.
Updates are infrequent — the webOS version trails the developer's Android and Fire TV builds by months, and new format support arrives slowly. IPTV stream stability depends entirely on the user's playlist source; the app provides no diagnostic tooling when a stream stalls. There is no Chromecast / AirPlay receiver mode, no transcoding fallback for unsupported audio tracks, and no library indexing — every browse is a live network walk.
CONCLUSION
Flux Player is the right install for LG TV owners who already run a home media library and need a TV-side client that doesn't refuse half their files. It is not a replacement for Plex or Emby if the household wants a polished interface, remote streaming, or library curation — those apps remain better at being apps. Flux Player is better at being a player. For users whose problem is "the file won't play", that's the trade worth making.
