 - Encoder: **libx264 CPU** only. `h264_v4l2m2m` is in `RETIRED_ENCODERS` because every Pi hardware revision we tested writes a non-conforming SPS that browsers reject.
 - Preset: libx264 `ultrafast` keeps a 1080p30 stream under ~1.5 cores on a Pi 4, leaving room for a second camera. See "HLS generation" for the full rationale.
 - USB: plug cameras into the Pi directly, not through an unpowered hub. Hub EMI faults show up as `usb-port: disabled by hub (EMI?)` + `xhci_hcd: Setup ERROR` in `dmesg` and wedge the whole USB controller until reboot.
