This repository contains the sending WebRTC server of the real-time point cloud streaming pipeline. The project contains a built in signalling server which is used to exchange SDP messages with the clients. The server is able to transmit data from either a directory within the project or by using point clouds captured by the PC capturing application. NACK based retranmssions are also enabled so frame reception is guaranteed as long as packet loss doesn't go too high. Bandwidth is estimated using Google Congestion Control (GCC) and the quality of the content is adapted using this estimation.
Building the project requires the use of Golang. To ensure comptability Golang version 1.21+ should be used. However, older version might also work but have not yet been tested. The project itself has been tested on both Windows and Ubuntu 20.04.
Following command line parameters can be used to change the behaviour of the application:
| Parameter | Name | Description | Example |
|---|---|---|---|
| -v | IP Filter | Forces the server to communicate using the interface with this IP | 192.168.10.1 |
| -p | Proxy Port | If enabled the server will receive frames from a UDP socket on this port | :8001 |
| -d | Content Directory | When not using the proxy port, a folder with content can be used instead | content_madfr |
| -f | Content Frame Rate | When not using the proxy port, the FPS at which the content is server | 30 |
| -s | Signaling IP | IP on which the signaling server will be created | 127.0.0.1:5678 |
| -m | Result Path | The path to which metrics are saved (folder + file without extension) | results/exp_1 |
To test the application you can use the following test content: 900 frame test sequence
