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

  1. 1Root a development LG TV, extract the native library files, and perform reverse engineering analysis using Ghidra.
  2. 2Consult webOS Homebrew community documentation to have the AI (Opus) locate internal implementations, addresses, and strings within the binaries.
  3. 3Write an initial C prototype to test whether the TV could render a native interface at 60 fps by rendering colored squares.
  4. 4Hand the problem over to the AI to hook up the local media stack, successfully rendering video output on the screen.
  5. 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.
  6. 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.

Reverse engineer software, websites, and games using Craft Anything

Study how a target website, app, game, or file works using real inspection tools, then have a coding agent build a new project in your specified tech stack, compare it against the original, and continuously refine it.

Create code-rendered videos using Claude Skill

Use the video-director skill to guide Claude Opus 5.5 (in Claude Code) through planning, writing, rendering, and QA-checking short code-rendered videos (HTML/Canvas/SVG converted to MP4). It ensures video quality through a phased workflow, QA scripts, and an evaluation system.

Replicating Stripe's internal AI agent workflow

Handle repetitive tasks using the same AI agent setup used internally by Stripe, reducing task completion time from 20 days to 4 days compared to standard Claude Code. This system is built using over 100 saved prompts (one per step) with multiple agents collaborating to handle the build work.
