Use VP8, not VP9 , if latency > bitrate efficiency. Force lag-in-frames=0 and deadline=realtime . Tune keyint to expected RF burst loss duration (e.g., 200ms loss → keyint ≤ 6 frames @30fps). Combine with small FEC (e.g., 10% overhead) outside libvpx. libvpx won’t win beauty contests, but it will keep video flowing through a burning radio link.
