@da2001 I can confirm that the sole source of observable latency in Phantom is due to network buffering, and you are right about the optical direct mode which bypasses the network entirely and does not show such latency.
You say that Phantom should just use the AES67 protocol because GStreamer on which it is built supports it. Although that's true, you're missing one key point completely: AES67 is designed for wired ethernet. It's so much easier to have latency guarantees using good old, dedicated copper wires... Wi-Fi or PLC are nowhere as reliable...
And now, think about the fact that 99% of the Phantom customer installations are wireless through either Wi-Fi or PLC.
I'll let you figure out why they are not using AES67.
