I’m facing significant amount of latency (1-2sec) with my Sonoptix sonar (v2.0.0) only when using the RTSP stream. I am using the RTSP stream to get the raw data from the sonar (rtsp://192.168.2.42:8554/raw), however it has 1-2 second latency when played with the VLC Player.
Meanwhile the “video” stream on the Browser (http://192.168.2.42/) shows near-zero latency (at least to the human eye).
I’m not sure we’ve specifically tested the RTSP latency, but I can ask internally whether it’s something we’ve run into and have any insight on.
That said, your question is likely be better posed to Sonoptix, as it is their device and firmware you’re communicating with / streaming from, so they hopefully have additional insights as to whether higher latency is expected and/or can be adjusted or compensated for.
Following up, the raw data stream was added via a firmware update after we did our primary testing of the Sonoptix Echo, and we haven’t meaningfully tested the feature.
