Same stream, side by side. first frame = play() → first painted
frame; latency = how far behind the live edge (embedplayer:
newest−presented PTS; jessibuca: stats.buf). For real
glass-to-glass, point at a live embed.cam URL and compare which
pane is more current. jessibuca (v3.3.26, the exact build embed.cam ships)
is fetched to /jessibuca/ by pnpm demo:jessibuca;
it is GPL and not part of this repo. embed.cam runs it
useWCS:false (WASM — the default here), so
ep decode = wasm vs jbc = WASM is the true head-to-head. For
a clean CPU read, start one at a time and use Chrome's Task Manager.
