GStreamer WebRTC Wrapper - GStreamer Pipelines - OWR Pipelines
|
Description
This page presents some GStreamer examples pipeline on supported platforms using the OpenWebRTC (OWR) Demo.
Launch OWR Demo
1. Install nodejs
sudo apt install nodejs
2. Start signaler
cd <path-to-gst-webrtc-wrapper>/tests/examples/signalers/owr node signaler.js
3. Start the web client on the PC. By default, the web client starts at port 8080. To use a different port provide it as an argument at the end.
#Start web client at port 8080 cd <path-to-gst-webrtc-wrapper>/tests/examples/signalers/owr node owr_web_client_example.js #Start web client at port 8082 cd <path-to-gst-webrtc-wrapper>/tests/examples/signalers/owr node owr_web_client_example.js 8082
4. Enter the web client at http://localhost:8080/ (remember to change port accordingly) and type the server (signaler) URL where it is running. For example http://10.251.101.124:8081, where 10.251.101.124 is the IP address of the system where the signaler is running. Then press 'join' in the web client.
5. To set up the WebRTC sender (media server) use one of the pipelines in the following sections.
