If you are seeking information on troubleshooting your audio & video connection, we recommend first checking out Troubleshooting Audio & Video for BrazenLive Video Broadcast and 1-on-1 Video Chats and then review the technical requirements below.
What Is BrazenLive & 1-on-1 Video Chat?
BrazenLive lives right within the Brazen virtual event platform and provides live video broadcast + screen sharing capabilities in the event. 1-on-1 Video Chat gives representatives the option to transition from a text-based conversation to a private video chat with an event attendee.
BrazenLive and 1-on-1 Video use Vonage technology, which is built using WebRTC. All multimedia traffic is routed through Vonage media servers; peer-to-peer connections are never used.
What Are the Technical Requirements?
Interactive Broadcasts & 1-on-1 Video Chats
Broadcast Hosts and Presenters participate in an Interactive Broadcast. They will see incoming video in real time and have the ability to share their video, audio, and screen. Interactive Broadcasts are delivered using WebRTC. These are the same requirements for users engaging in 1-on-1 video chats.
Hardware
BrazenLive and 1-on-1 video chats require access to each user's camera and microphone. Users are prompted for this access when using BrazenLive or entering a 1-on-1 chat.
Supported Browsers
All modern browsers which support WebRTC, 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: an Interactive Broadcast with a Host, a Presenter, and the Presenter's shared screen is three streams, so each Host and 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 and 1-on-1 Video automatically negotiate the best possible route for multimedia traffic. Clients 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 will resolve video issues that can semi-frequently occur during events.
WebSockets
WebSockets are recommended, but not required, for BrazenLive and 1-on-1 Video. Certain metadata, such as other users' connectivity status, is relayed over a WebSocket connection and is lost when this connection type is blocked.
Proxies
BrazenLive and 1-on-1 Video work as normal through transparent proxies. Proxies which inspect and or alter traffic may interfere with BrazenLive and 1-on-1 Video. Please ask your account manager for more details.
Live Streaming
Broadcast viewers see BrazenLive as a Live Stream. This is a single consolidated video showing all Hosts and Presenters, along with any shared screens. Live Streams are delayed by roughly 15 seconds. Live Stream viewers are not given the option to broadcast video or audio. Because Live Streams are delivered over HTTP Live Streaming, they have much less stringent technical requirements.
Hardware
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
Live Stream 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
No port requirements
WebSockets
Live streaming does not require WebSockets.
Proxies
HTTP Live Streaming is treated as normal HTTP traffic and should not be affected by proxies.
