visio-display CLI

visio-display is installed with the visio-schema package. It takes one data source plus at least one output.

Examples​

# Live TCP (device port 50001, over the Wi-Fi hotspot) → record to MCAP
visio-display --tcp 192.168.4.1:50001 --out capture.mcap

# Replay an MCAP into Rerun for visualization
visio-display --mcap-in capture.mcap --rerun

# Live stream → Foxglove WebSocket bridge (see below)
visio-display --tcp 192.168.4.1:50001 --foxglove

Options​

  • Source (choose one): --tcp HOST[:PORT] · --mcap-in FILE
  • Output (at least one): --out FILE.mcap · --foxglove [--port 8765] · --rerun
note

EGO1's TCP port is 50001 — write it explicitly, e.g. --tcp 192.168.4.1:50001.

View a "live" stream in Foxglove Studio​

Foxglove Studio can't connect to the device directly. Start a Foxglove WebSocket bridge with visio-display first:

visio-display --tcp 192.168.4.1:50001 --foxglove
# → Foxglove WebSocket server on ws://localhost:8765

Then in Foxglove Studio: Open connection → Foxglove WebSocket → ws://localhost:8765.

To view an already-recorded file you don't need the bridge — just File ▸ Open local file on the .mcap (see Retrieve & view data).
