The Pubnub ID should be used to connect the GstWebRTCWrapperbin pipeline.


== Nvidia Xavier/TX2 ==
The '''ID Number''' will change whenever you open the [https://stephenlb.github.io/webrtc-sdk/ PubNub WebRTC Demo], so take it into account to use the new number for '''PEER_CHANNEL'''.


This pipeline are creating using the Nvidia resources like cameras, video codecs.

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.

  • Safari not yet supported


Figure 1. Pubnub Web Demo


The Pubnub ID should be used to connect the GstWebRTCWrapperbin pipeline. Take PEER_CHANNEL=136' as highlighted in the image above as ID Number, for the following examples.



Figure 2. WebRTC-Wrapper on work


The ID Number will change whenever you open the PubNub WebRTC Demo, so take it into account to use the new number for PEER_CHANNEL.

WebRTC connection along xirsys CoTurn

This example includes the Xirsys credentials to enable the Xirsys CoTurn service, the xirsys credentials are also used in the 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>

AUDIO_DEVICE="plughw:0,7" # Assign your audio device

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 one.

Go to Xirsys Dashboard services.


Figure 4. Xirsys Dashboard.
