Vehicle Video Service

This repository builds and packages the vehicle video service as one deployable stack:

• vehicle_video_service: camera capture, RTMP push, MQTT status and record query handling.
• SRS live instance: low-latency live playback over RTMP to WebRTC/WHEP.
• SRS record instance: DVR segment recording and HTTP file serving.
• systemd units for all three services.

Build

./scripts/build_video.sh

If you need to rebuild SRS from the bundled source:

./scripts/build_srs.sh

Package

./scripts/package_release.sh

Or build everything and package it in one command:

./scripts/build_all.sh

The output is:

dist/vehicle-video-service-aarch64.tar.gz
