Network Ports

All ports are plain TCP unless noted otherwise.

Control and clock ports

9998 (IN, UDP)

GStreamer NetTimeProvider — clients use this to synchronise their pipeline clock with voctocore. Required for any client that sends or receives A/V streams (TCP sources, ffmpeg sinks, voctogui previews).

9999 (IN)

Control interface. voctogui and other clients (e.g. voctoremote, voctomidi) connect here to send commands and receive state updates.

Source input ports

10000+ (IN)

TCP A/V sources (kind = tcp). Assigned sequentially in the order sources appear in mix/sources. First TCP source → 10000, second → 10001, and so on.

14000 (IN)

Overlay source port.

16000+ (IN)

Background source input ports. Assigned sequentially per background source.

17000+ (IN)

Blinder video source ports. Assigned sequentially per blinder video source.

18000 (IN)

Audio blinder source port.

Mix output ports

11000 (OUT)

Mix recording output (raw Matroska A/V). Full-quality mix used for recording.

11100 (OUT)

Mix preview output (encoded, lower resolution). Used by voctogui to display the mix preview.

Source output ports

13000+ (OUT)

Raw source output mirrors. Assigned sequentially per source. Used by voctogui when previews are disabled and the GUI runs on the same machine.

13100+ (OUT)

Encoded source previews (when previews/enabled = true). Assigned sequentially per source.

Live output ports

15000 (OUT)

Mix live output (blinder-controlled). The stream sent to live audiences; blanked when the blinder is active.

15100 (OUT)

Mix live preview output.

15001+ (OUT)

Extra live source outputs (mix/livesources). Assigned sequentially.

Other ports

19000 (OUT)

Local playout output.

20000 (OUT)

Metrics served in prometheus format.

Viewing port assignments

voctogui can show the current port assignment table. Enable the ports panel via toolbar/ports = true in the configuration or use the toolbar button if it is visible.

You can also query port state from the control interface (port 9999) by sending the command report_ports.
