Description
This page presents some GStreamer examples pipeline on supported platforms using PubNub Demo.
Bring up the PubNub Demo
Open the PubNub WebRTC Demo on a Chrome or a Chromium browser.
Figure 3. Pubnub Web Demo
The Pubnub ID should be used to connect the GstWebRTCWrapperbin pipeline.
Nvidia Xavier/TX2
This pipeline are creating using the Nvidia resources like cameras, video codecs.

WebRTC connection along xirsys CoTurn
This example includes the Xirsys credentials to enable the Xirsys CoTurn service, the xirsys credentials is also used in above pipelines as well. The user should be generated his/her xirsys credentials before continuing, see the Xirsys Credentials.
1. Open the Pubnub demo on the mobile device and follow the section Bring up the PubNub Demo
https://stephenlb.github.io/webrtc-sdk
2. Run the below pipeline setting the Xirsys credentials up.
USER_CHANNEL=123
PEER_CHANNEL=136
XIRSYS_IDENT=<ident>
XIRSYS_SECRET=<secret>
XIRSYS_CHANNEL=<channel>
XIRSYS_PATH=<path>

Appendix
Find audio device
Run the command (in the terminal)
aplay -l
The output looks like
**** List of PLAYBACK Hardware Devices ****
card 0: Intel [HDA Intel], device 0: ALC262 Analog [ALC262 Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
The device for this is plughw:0,0. The two zeros come from the device 0 and Subdevice #0.
Xirsys Credentials
Go to Xirsys login panel
Figure 3. Xirsys Account.
Note: Create a Xirsys account if you do not have it.
Go to Xirsys Dashboard services.
Figure 4. Xirsys Dashboard.
Take the Xirsys credentials to set up the WebRTC session.
