Generate (or load) an RGBD clip, encode it in-browser via WebCodecs VP9, then decode and view it back. The RGB pane is what a legacy player shows; depth (and other uint16 signals) ride along, bit-exact. On Chromium this runs entirely on WebCodecs with no WASM; other engines transparently load a small libvpx-WASM fallback.
WebCodecs path isn't bit-exact here, so the demo will use the
bundled libvpx-WASM fallback (correct, just slower to load). For the fastest, fully native path, try
Chrome or Edge.
