About: With the failover mechanism, LTN Live Video Cloud provides increased ingest reliability for SRT and RTMP inputs. It allows configuring an input with two ingest points for a primary and secondary signal. Both signals are treated equally. Live Video Cloud automatically switches to the currently unused signal based on stream stats, such as CC errors and signal interruptions. Even if one signal breaks, consumers of the input experience a continuous stream.
For certain use cases, forcing Live Video Cloud to use a specific signal and temporarily disable automatic failover can be helpful. While a signal is forced, Live Video Cloud does not switch automatically, and the input acts as if failover was not configured.
Force a signal
Incoming signals of an input with failover enabled are treated equally. The first signal Live Video Cloud receives is used and gets the "active" label.
To force a signal and disable the failover mechanism:
- In the input inspector, select the signal you want to force.
- Press "Force Signal" in bottom left corner of the signal flyout.
- Confirm the action by clicking on "Force".
- If you want to enable the automatic failover again, click "Activate".
- The "active" label appears, and failover is ready again.
Identify a forced signal
Depending on the states of the signals, the input represents a consolidated state. If an input is configured with failover enabled and a signal is forced, the input is in an attention state. Live Video Cloud expects automatic failover to be desired when configured, and forcing a signal disables automatic failover.
A – Signal indicator: Displays signal indicator in attention color.
B – Status message: Displays "Attention" state of input, including description "Signal forced".
C – Forced label: Shows "forced" label, which substitutes the "active" label.
The input status and signal indicators are shown in different interface parts to identify the forced signal quickly.
