Nerd sniping myself into a rabbit hole
summary
Android app proxies YouTube audio to Sonos by sniffing the phone app traffic, extracting the MP4 audio track, remuxing AAC into ADTS frames and serving it over HTTP on the phone so Sonos will play it. Uses soco to control Sonos, ffmpeg to inspect and extract streams, and a small MP4 parser to rebuild ADTS headers. Works end-to-end: network capture → ADTS remux → Sonos shows track title and cover art and plays audio.
