BrazenLive Broadcasts provide live video broadcast and screen sharing capabilities in your event. Group Video allows you to hold a live video/audio chat between booth hosts and participants, with up to a total of nine people at a time. One-on-One (1:1) Video Chat gives Representatives the option to transition from a text-based conversation to a private video chat with an event Attendee.
All three features use Vonage technology, which is built using WebRTC. All multimedia traffic is routed through Vonage media servers; peer-to-peer connections are never used. Hosts, Presenters, and Representatives see incoming video in real time.
If you are troubleshooting your audio and video connection, first review Troubleshooting Audio & Video for BrazenLive Video Broadcast and 1-on-1 Video Chats, then review the technical requirements below.
Technical Requirements
Hardware
BrazenLive Broadcasts, Group Video, and 1:1 video chats require access to each user's camera and microphone, and for Hosts and Presenters, access to their device's screen.
Supported Browsers
All modern browsers which support WebRTC are supported, including the latest versions of:
- Chrome (desktop and mobile)
- Version 83 and higher for Windows
- Safari (desktop and mobile; screen sharing feature is limited)
- Firefox
- MS Edge
- NOTE: Older, non-Chromium versions of Microsoft Edge (versions less than 79) do not support screen sharing capabilities
Bandwidth
A minimum of 350Kbps available bandwidth per stream is recommended. A stream is any incoming or outgoing video source.
Example: a BrazenLive Broadcast with a Presenter in the Host role, an additional Presenter, and a shared screen is three streams, so each Presenter should have at least 3×350Kbps available bandwidth.
Required Domains
Users' browsers must be able to reach the following domains directly, in addition to the standard Brazen Connect domains:
-
*.tokbox.com
-
*.opentok.com
Ports
BrazenLive Broadcasts, Group Video, and 1:1 Video Chat automatically negotiate the best possible route for multimedia traffic. Users must be able to send and receive TCP traffic on port 443. We also require allowing traffic on UDP port 3478, as UDP's speed-over-reliability approach is much better suited to streaming multimedia. This resolves video issues that can semi-frequently occur during events.
WebSockets
WebSockets are recommended, but not required, for BrazenLive Broadcasts, Group Video, and 1:1 Video Chat. Certain metadata, such as other users' connectivity status, is relayed over a WebSocket connection and is lost when this connection type is blocked.
Proxies
All three features work as normal through transparent proxies. Proxies which inspect and or alter traffic may interfere with them, however. Please ask your Account Manager for more details.
BrazenLive Broadcast Streaming Requirements
BrazenLive Broadcast viewers see the broadcast as a live stream in real time. This is a single consolidated video showing all Presenters, along with any shared screens. BrazenLive viewers cannot share their video, audio, or screen. Because these live streams are delivered over HTTP Live Streaming, they have much less stringent technical requirements.
Hardware
There are no hardware requirements.
Supported Browsers
All modern browsers, including the latest versions of:
- Chrome (desktop and mobile)
- Version 83 and higher for Windows
- Safari (desktop and mobile; screen sharing feature is limited)
- Firefox
- MS Edge
- NOTE: Older, non-Chromium versions of Microsoft Edge (versions less than 79) do not support screen sharing capabilities
Bandwidth
BrazenLive Broadcast viewers always receive exactly one incoming stream and never have outgoing streams of their own. A minimum of 350Kbps available bandwidth is recommended.
Required Domains
Users' browsers must be able to reach the following domains directly, in addition to the standard Brazen Connect domains:
-
*.tokbox.com
-
*.opentok.com
Ports
There are no port requirements.
WebSockets
BrazenLive streaming does not require WebSockets.
Proxies
HTTP Live Streaming is treated as normal HTTP traffic and should not be affected by proxies.
