mrg-iot stream

Camera-equipped devices are proxied over RTSP. list, open, and url watch them; push sends video the other way, into a device. capture streams the experiment's live network traffic into Wireshark.

Streams hold a tunnel open

A stream is continuous, so open, url, push, and capture keep running to hold their tunnel open; closing the command closes the feed. The local port is assigned per session, which is why stream list prints a <port> placeholder.

Requirements

• stream open needs VLC.
• stream push needs ffmpeg.
• stream capture needs Wireshark, unless it writes to a file with --write.

Flags

Every command that talks to a running experiment takes the same four experiment flags, each with a default, so you usually pass only -e:

Argument	Description
--project, -p	Project name. Default: your only project; required when you belong to several.
--experiment, -e	Experiment name. Default: your username.
--realization, -r	Realization name. Default: realiot.
--xdc, -x	XDC name. Default: <experiment>xdc.

Commands

Command	What it does
stream list	Name the experiment's cameras.
stream open	VLC viewers for every camera.
stream url	Print the RTSP URLs and keep forwarding.
stream push	Send a video stream to a device.
stream capture	Watch the experiment's live traffic in Wireshark.
