Network inputs

SRT Input

Receive a live SRT stream.

Before you start

Open the intended collection and layout. For capture or network inputs, have the device or sender available.

Where to find it

Sources > Add > SRT Input.

Use it

Open the scene that will contain the source.
Choose Add in Sources.
Select SRT Input in Create Source.
Enter a name and choose New.
Choose Mode: caller, listener, or rendezvous.
Enter Host and Port.
Enter Stream ID if required.
Match encryption and latency with the sender.
Check the generated Input URL.
Choose Save and Close (or OK where shown).
Check the source in Preview before taking it to Program.

Controls and additional tasks

Port accepts 1–65535. A passphrase, if used, needs at least 10 characters. Encryption key length 0 means no encryption. Local and peer latency trade delay for network tolerance. Width/Height set the scene item size, not the incoming stream resolution. Use Extra input options only with settings supplied for your feed.

Control reference

Control	Use
Mode	Choose caller, listener, or rendezvous connection mode.
Host	Enter the remote host or local listener address for this SRT input.
Port	Enter the SRT UDP port, from 1 to 65535.
Stream ID	Optional SRT stream ID required by some senders or receivers.
Passphrase	Optional SRT encryption passphrase. SRT requires at least 10 characters when set.
Encryption key length	Choose the SRT encryption key length. Use 0 only when encryption is not required.
Latency (ms)	Set local SRT receive latency in milliseconds.
Peer latency (ms)	Set peer SRT latency in milliseconds.
Input URL	Generated SRT input URL based on the connection, security, and timing settings.
Width	Set the scene item width. The incoming stream resolution is decoded from the SRT input.
Height	Set the scene item height. The incoming stream frame timing is decoded from the SRT input.
Extra input options	Optional safe input-side arguments for this SRT input.
Save and Close	Save SRT Input settings. Shortcut: Ctrl+S.
Cancel	Close without saving changes.

If something is wrong

If it does not connect, match mode, host, port, stream ID, and encryption with the sender.

Stop or remove

Hide the source to stop showing its picture. Use its available playback/connection stop control when you need to stop the input itself. Remove the source item from the scene when it is no longer needed. Shared sources can still be used in other scenes.
