RTC @Scale, Video Session
summary
AV1 runs in Duo at low resolutions and shows a single-digit battery increase from the non‑AV1 baseline when first deployed about 1–1.5 years ago and then improves as encoder speedups land. Tests use the open‑source AOM encoder wrapped inside closed‑source settings, metrics run on 30–40 screen‑content clips with identical command lines to produce PSNR, SSIM and VMAF, and AV1 SVC in Chrome is supported for layered RTC use. No mainstream GPU AV1 encoder is yet available.
