The built-in WASM player (frontend/static/vendor/hevcjs/hevc-core.js)
rendered washed-out, green/red-shifted video. Two causes, both fixed:
- VideoFrame path (Chrome): the I420 VideoFrame was created without a
colorSpace, so the browser defaulted to BT.601 limited -> hue shift,
and guessed the range -> washout. Set explicit BT.709, fullRange:false.
- WebGL fallback shader: used BT.709 FULL-range coefficients on
limited-range camera output -> washout/desaturation. Switched to
BT.709 limited-range conversion ((Y-16)*255/219, chroma centered 128).
VERSION -> 0.0.116.
