Install a lightweight Chrome extension that forces YouTube to serve H.264 (avc1) by blocking VP8, VP9, and AV1 via MediaSource.isTypeSupported. This enables Wave5 hardware video decoding on YouTube, which only supports H.264 and HEVC, without requiring a third-party extension to be manually installed through the Chrome Web Store before use.
Installed at /usr/lib/chromium/extensions/force-h264-youtube and --load-extension is appended to the chromium-wrapper launch script.
