OLD (Legacy Workflows)

This document contains legacy WRecorder workflows that are no longer the primary path.

Legacy files

• Single-stream OpenCV: old/opencv_streamer.py, old/opencv_receiver.py
• Demo IP discovery scripts: old/demo_ip_discovery_broadcaster.py, old/demo_ip_discovery_receiver.py
• Single-stream GStreamer: old/gstreamer_streamer.py, old/gstreamer_receiver.py

Single Stream OpenCV Method (Old)

This method uses OpenCV to capture and display video frames, and ZeroMQ (pyzmq) to transmit frames over the network. It supports a single camera stream.

Launch stream command

Parameters:

• auto-ip-discovery: Controls auto IP discovery, either on or off (default: off)
• discovery-port: Port for IP discovery packets (must differ from broadcast port) (default: 5556)
• discovery-timeout: Delay in seconds to allow IP discovery (default: 15)
• broadcast-port: Stream port, must match receiver (default: 5555)
• camera-id: Video device index (default: 0)

Example:

python3 old/opencv_streamer.py --auto-ip-discovery=on --discovery-timeout=30 --broadcast-port=5555 --camera-id=0

Launch receiver command

Parameters:

• auto-ip-discovery: Toggle auto IP discovery (default: off)
• discovery-port: Port for IP discovery packets (must differ from broadcast port) (default: 5556)
• discovery-timeout: Delay in seconds to allow IP discovery (default: 15)
• broadcast-ip: Manual IP if auto discovery is disabled (default: 0.0.0.0)
• broadcast-port: Stream port, must match broadcaster (default: 5555)

Example:

python3 old/opencv_receiver.py --auto-ip-discovery=on --discovery-timeout=30 --broadcast-port=5555

Single Stream GStreamer Method (Old)

This method uses GStreamer to capture, display, and transmit frames. It supports a single stream.

Launch stream command

Parameters:

• ip: Receiver IP, available from hostname -I
• port: Stream port (must match receiver)
• video: Video device index, appended to /dev/video

Example:

python3 old/gstreamer_streamer.py -ip=172.20.10.3 -port=5000 -video=0

Launch receiver command

Parameters:

• port: Stream port, must match broadcaster

Example:

python3 old/gstreamer_receiver.py -port=5000

Legacy troubleshooting notes

• No camera detected: verify device node (for example /dev/video0) and permissions.
• Connection refused: verify broadcaster IP/port and firewall rules.
• Auto-discovery fails: verify discovery ports and UDP broadcast support.
