Quick setup · Short test

Record whether the phone is hot, whether a local recording also stutters, and whether another device sees the fault. Repeat the test in the same place without downloads or updates. Smooth local footage with a poor live output points toward the connection; a hot device with stuttering local footage points toward load and temperature.

Do not change network, location and resolution simultaneously. Follow the device manufacturer’s cooling guidance and avoid rapid temperature changes. Repeat a longer test after improvement: a smooth opening minute does not prove the entire stream is stable.

Before you go live

Keep your existing configuration and original source file first. Change one parameter at a time. Check a short recording or the actual viewer output, rather than relying only on the editor. Restore the recorded baseline if the result gets worse.
