Leave "Camera audio" off to send a silent AAC track (YouTube requires audio). Adding a name that already exists updates that entry.
Schedule
Rules run [start, end) in the container's timezone. An end at or before the start crosses midnight. The first matching rule wins, so use ↑/↓ to reorder and ⧉ to duplicate a rule. With no match the stream goes offline. The schedule only drives output while mode is Schedule.
Rotation fill
Tick two or more cameras, pick a window, and this appends one plain schedule rule per time slot, cycling through the cameras in the order listed above. Review (and reorder if needed), then press Save schedule. Since the first match wins, move the generated block above any broad rule covering the same hours — or Clear all first for a fresh start.
