Reverse engineering an LG TV with Claude Code to build a native Plex client
The author used Claude Code and Ghidra to reverse engineer the native media stack of a 2019 LG TV, building the PlxNative client from scratch using C and Rust. This cut the official Plex app's 30-second load time down to about 3 seconds while achieving a native 60 fps OpenGL UI on the TV.

Steps
- 1Root a development LG TV, extract the native library files, and perform reverse engineering analysis using Ghidra.
- 2Consult webOS Homebrew community documentation to have the AI (Opus) locate internal implementations, addresses, and strings within the binaries.
- 3Write an initial C prototype to test whether the TV could render a native interface at 60 fps by rendering colored squares.
- 4Hand the problem over to the AI to hook up the local media stack, successfully rendering video output on the screen.
- 5Address memory and ownership errors (such as stack overflows) caused by C refactoring by progressively migrating the project to Rust to leverage strict compiler checks.
- 6Handwrite shaders and a custom UI library on top of OpenGL to implement navigation, focus handling, animation, and caching, ultimately hitting the 60 fps performance target.
