What is the difference between adding a new Sink vs. adding a new Output Stream for SRT workflows? Is there any implication for system resources when using one over the other?

(i) Adding a new Sink takes advantage of the already encoded signal and enables easy replication of the output on a new IP, port, NIC, or even encapsulating it in SRT.

Example: For 10 remote clients who all want to view the same SRT stream, simply use “Configure Sinks” and within the same Pipeline – add sinks by bumping the port number for each additional remote client; E.g., client 1 – port 5051, client 2 – port 5052, and so on.

(ii) A new Output stream is used if the video configuration or bandwidth needs to vary between outputs.

Example: For 10 remote clients who all want to view the same SRT stream, but 5 of them want 20Mbps, and the other 5 need to use a lower quality, 8Mbps. In this case, we cannot only use “Configure Sinks” and different port numbers. We must create two separate output streams – one for 20Mbps and another for 8Mbps, and then again use the port numbers to provide 5 of each for the receiving clients.

(iii) Resource Utilization

There is no notable resource utilization differential between using Add Sink vs. Add Output Stream, where all settings are equal.
