Could you build this?
Partial The browser extension UI and audio transcoding via WebAssembly FFmpeg are straightforward, but parsing and extracting streaming audio directly from YouTube violates platform protections and requires frequently maintained deciphering algorithms.
What it would actually take: Building a browser extension that extracts media streams from platforms like YouTube requires embedding or running dynamic cipher-extracting scripts (similar to yt-dlp's JS challenge solver) inside the browser extension context. Once raw stream chunks are fetched, the extension needs a WebAssembly-compiled build of FFmpeg or libmp3lame to demux and re-encode the audio streams into MP3 locally. Maintaining this requires ongoing reverse-engineering expertise to handle platform stream obfuscation updates and signature deciphers.
