Extract the install that was applied by hand to the Jetson Nano into a single checkout that builds itself for whatever Jetson it lands on. The two nodes on the rig share no JetPack — tegra210 caps at 4, tegra234 needs 5+ — so nothing binary is portable between them. The source and the procedure are: install.sh detects the platform (L4T / JetPack / SoC), installs deps, builds the OrbbecSDK and the preview server from source locally, and generates a per-user config and systemd unit. The tested bridge.py ships verbatim; all machine-specific paths live in the generated config, so it stays unmodified — its one hardcoded path is made home-relative. The retired GStreamer/RTSP target is dropped: the direct route encodes no video. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

# One command, the same on every Jetson: installs the Ithaca capture node from this
|
|
# checkout. Detects the platform, installs dependencies, builds the C++ against a
|
|
# locally-built OrbbecSDK, generates a config and a service for the CURRENT user,
|
|
# and starts the bridge.
|
|
#
|
|
# Idempotent: safe to re-run after a git pull. It rebuilds the server, rewrites the
|
|
# config and unit, and restarts the service; it does not touch a working SDK build.
|
|
#
|
|
# Why a script and not a prebuilt image: the two Jetsons here have no common
|
|
# JetPack — tegra210 caps at 4, tegra234 needs 5+ — so nothing binary is portable
|
|
# between them. The source and this procedure are; the binaries are made locally.
