PlxNative

A fast, unofficial Plex client for LG webOS televisions. Native, not a web page — the interface is drawn straight on the GPU at 60 fps, and video plays on the TV's own decoder.

Website: plxnative.com · Install guide · Troubleshooting

In daily use on a 2019 LG set. PlxNative is an independent project and is not affiliated with Plex, Inc. or LG. The same install steps are in the repo: installation guide.

Why this exists

The official Plex app on my old LG is slow. Scrolling a shelf stutters, opening a poster takes a beat too long. It behaves like a web page because it is one: a web app running in the television's Chromium. Patching it doesn't help — the ceiling isn't the code, it's the browser.

So I threw the browser away.

PlxNative draws straight on the GPU and hands video to the same silicon the built-in apps use. No Chromium, no JavaScript, no web view. It just draws. Almost all of it is Rust, and I use it every day to watch things off my server in the next room.

What it looks like

Real captures of the app, not mockups: the same code that runs on the television, on the desktop simulator, browsing a demo library of openly licensed films (credits). make screenshots regenerates them.

Home

Home — a rotating hero from what you're partway through and what's just landed, shelves under it.

Library

Library — a library opens on its own shelves: what you're partway through, with the time left under the focused card, and what just landed. Further down is the full grid, with sort, filter (including unwatched-only) and an A–Z rail down the side (pictured here).

Search

Search — one query across every server you can reach, results grouped by kind.

Player

Player — the transport with chapters and track menus, drawn over video the television decodes itself. (In this capture the frame under it was decoded by the simulator.)

What it does

Will it work on my television?

It needs webOS 4.0 or newer, with one tested exception: a 2016 set on webOS 3.4.3 signs in, browses, searches and plays (direct play, transcodes, subtitles and seeking) through Developer Mode. Other 3.x releases are untested, and anything older than 3.4 is unknown. Past that, it most likely will. I develop and test on a 2019 set, and opt-in usage reports show video playing on sets from 2018 through the newest, on webOS 11 — both direct play and server transcodes, Developer Mode installs included.

Known issues

Where What happens
Some 2019 sets on LG's k5lp or k3lp chip, installed through Developer Mode Video won't play. On these sets LG's Developer Mode sandbox can withhold a device the video path needs — Kodi and Moonlight hit the same wall. The app checks for it and says so instead of crashing; other sets on the same chip play normally. On a rooted TV with Homebrew Channel, the failure screen offers Repair, which applies the Homebrew Channel fix to the sandbox (one owner fixed it this way from a root shell; the button itself hasn't been run on an affected set yet). Without root there is no fix.
2018 sets on firmware that reports platform release 3.9.3 Sign-in and browsing work, but video has never been seen to start on one, and no error is reported either: #249.
webOS 3.x Seeking restarts the stream at the new position instead of jumping in place, so each seek takes a moment longer. In-place seek depends on the internal layout of LG's 4.x media player, and on 3.4 that layout differs.
Sets on LG's k6hp chip A crash seen in opt-in crash reports and not reproduced here, because I have no such set: #174.

Rooted or not

No root is needed. A regular TV in Developer Mode runs everything except the k5lp/k3lp Repair above. What Developer Mode costs you is renewal: if the session lapses, LG removes the apps installed through it (how to keep them). A rooted TV with Homebrew Channel has no expiry.

If something goes wrong, check Troubleshooting first, then tell me what happened — and if you own one of the sets above, it working is as useful a report as it failing.

Installing

First time installing an app outside the LG Content Store? Follow the step-by-step installation guide. It starts with a regular LG webOS TV, a computer on the same network, and a Plex account with access to your own or a shared server. No root is required.

Set up LG Developer Mode and connect with webOS Dev Manager, then choose:

Already have Homebrew Channel? Find PlxNative in its catalogue and select Install. Skip the computer setup.

Developer Mode needs periodic renewal. If it expires and LG disables Developer Mode, apps installed through it are removed. Installing Homebrew Channel through Developer Mode does not remove that requirement. The guide explains how to renew the session.

For manual .ipk downloads, verify the release checksum before installing. Homebrew Channel verifies catalogue downloads for you.

Nightly builds

Every day main moves, CI cuts a nightly .ipk from wherever it stands. It installs beside the regular app as "PlxNative Nightly" — its own tile, its own sign-in — so trying it never touches the release you already trust.

With Homebrew Channel: under Settings choose Add repository, enter https://plxnative.com/nightly/repo.json, then install PlxNative Nightly. Every later nightly appears there as an update. The nightly builds guide has the steps, how the versions work and what to do if something goes wrong.

Without it: each build is a prerelease, and the newest is always linked from plxnative.com/nightly/latest.json. Install it with Dev Manager; a package installed that way does not update itself.

It is not tested on a television. It passes the same automated build and packaging checks a release does, but nobody has watched it play. Each nightly is deleted 30 days after it is published, so link to a specific .ipk at your own risk.

Release candidates

Before a release, CI may publish a release candidate as a prerelease named like PlxNative 0.8.0-rc.1. It is the release build itself, so it installs as the regular PlxNative app, replacing the one you have the way an update would. It is not in the Homebrew Channel, and the Channel will not offer the final release over it either: reinstall the final by hand once it is out.

Privacy

Your library data never reaches me. The app talks to your Plex server, to plex.tv to sign in, and to discover.provider.plex.tv for cast biographies.

Crash reports and usage analytics are off until you turn them on — two separate first-run questions, each answerable with Don't Share, both reversible later under Account → Settings → Privacy & data. No title, search term, subtitle line, server name or address can appear in any report. PRIVACY.md is the whole statement, including the schemas.

ASS/SSA subtitles render natively during direct play, including styles, positioning, overlapping signs and dialogue, karaoke, and embedded fonts. External ASS files retain their original scripts. A re-encode still burns the selected subtitle on the server; over a remux the app draws a sidecar, and an embedded track when the link is local and the Part is 1..=30000 kbps, and otherwise the server burns it.

The honest scope

I built this for how I watch, so it's narrower than Plex's:

If that fits, it's genuinely nice to use. If it doesn't, the official app will serve you better.

Contributing

Issues and pull requests are welcome, especially from anyone whose television or library differs from mine — docs/building.md is the build and the test loop, and says what hardware I most need help with. Feature ideas go to Discussions > Ideas. Security issues go through SECURITY.md rather than a public issue.

Plx-native
What is this?PlxNative is a fast, unofficial Plex client built specifically for LG webOS TVs. It draws its interface directly on the GPU at 60 fps and hands video off to the TV's own hardware decoder, instead of running as a web app inside the TV's Chromium browser like the official Plex client.
How do I get it installed on my TV?Enable LG Developer Mode on the TV and connect with webOS Dev Manager from a computer, then either install PlxNative directly (future .ipk updates come from your computer) or install Homebrew Channel first so updates come from the remote. If you already have Homebrew Channel, you can just find PlxNative in its catalogue.
Do I need to root my TV first?No. A regular TV in Developer Mode runs everything, with one exception: a repair for a specific sandbox bug on some 2019 LG k5lp/k3lp-chip sets only works if the TV has Homebrew Channel (root) installed.
Will it work on any LG webOS TV?It needs webOS 4.0 or newer; a 2016 set on webOS 3.4.3 works via Developer Mode but with slower seeking, and anything older than 3.4 is untested. Some 2019 sets with LG's k5lp/k3lp chip can't play video at all through Developer Mode due to a sandbox limitation Kodi and Moonlight also hit.
Where does my viewing and library data go?PlxNative only talks to your Plex server, to plex.tv for sign-in, and to discover.provider.plex.tv for cast bios — your library data never reaches the developer. Crash reports and usage analytics are off by default, each a separate opt-in that can be reversed later, and no title, search term, or server address can appear in them.
Does it support 4K and Dolby Vision?Yes — it can direct play H.264 and HEVC including 4K, 10-bit, and Dolby Vision profiles 5 and 8 with E-AC-3 Atmos when the TV's codec table supports it. Anything else falls back to the server transcoding, and playback can be switched to Auto to follow a link whose speed changes.
What's the difference between nightly builds and release candidates?Nightlies are CI builds cut daily from the main branch and install side-by-side as a separate 'PlxNative Nightly' app that auto-deletes 30 days after publishing. Release candidates are full release builds that install as the regular PlxNative app itself, replacing your current version ahead of the final release.
Can I use it for music or photos too?No — the scope is intentionally narrow to movies and TV shows only, with no support for music, photos, or live TV/DVR.
Why build a whole new client instead of improving the official Plex app?The official LG Plex app is really a web app running in the TV's Chromium browser, so scrolling and navigation hit a performance ceiling that patching can't fix. PlxNative throws out the browser entirely and draws straight on the GPU while handing video to the TV's native decoder.
