The viewer launched mpv with `--untimed`, which displays each video
frame the instant it decodes and ignores audio timestamps. Sharing a
desktop (no audio) that just minimizes latency, but sharing a *video*
made its audio drift progressively out of sync — confirmed in a field
test watching a video together. Remove the flag so mpv paces video to
the audio clock; the remaining low-latency flags keep lag negligible for
desktop pointing.
