Each token item has a quick action menu that provides various options: Disable/Enable token, Delete Token, Online Broadcaster, and Token Settings.

Broadcaster

The Live Broadcaster interface is a lightweight hosted web application which allows you to instantly begin broadcasting your live stream to your global audience without installing any software.

The Broadcaster has the following user interface controls:

• Video Devices
• Audio Devices
• Record
• Settings
• Picture-in-Picture
• Share Broadcast

More detail about each of these can be found below.

Video devices

By choosing the camera icon you will see the available capture devices from your computer. This may include built-in cameras or accessories such as a USB camera. Virtual cameras may also be present such as with OBS or NDI devices. You can also begin screen sharing from this menu.

Video test

There is a Video Test option you can use that may be helpful alternative to sharing your video for testing a live streaming setup end-to-end.

You can also disable the camera option entirely and send an audio-only stream.

Audio devices

The Mic input selector allow you to select between the microphone inputs that are active on your computer.

You can alternatively mute the audio entirely for video only streaming.

Start broadcast

Click the green Start button to begin a broadcast. The timecode above the button displays the duration of the stream. Click the red Stop button when you are finished publishing.

Record

When recording is enabled for a publish token a record button will be present.

You can toggle the record feature only when you are not broadcasting live. If you are in a live broadcasting, you must stop the broadcast first to toggle the button and begin recording.

Settings

The settings menu provides a few options to change the behavior of the broadcaster. It allows you to modify media settings, adjust the video display, and report issues with the Publisher.

It allows you to manipulate camera quality, capture size, frame rate and aspect ratio. You can use these controls to tune the stream for quality, size and even codec (eg. H264, VP9 or AV1) which can provide certain benefits and capabilities. These adjustments can be very helpful when streaming to a wide variety of devices and network conditions. For example if the broadcaster is streaming from a very bandwidth-limited location, you have the ability to lower the quality, capture-size and framerate to maintain a smooth stream. More details about this pop-up are described below.

• Media Settings
• Media Stats provides diagnostic details about the performance of the broadcast stream
• Video Display Adjust
• Report Publisher Issue can be used to request help from support and identify problems that occur while streaming.

Disabled Settings Cannot Be Changed

Some settings must be set before beginning to publish your broadcast. If the item is greyed out and disabled it is because the publish token may not have the feature enabled or a broadcast is already live and can no longer be changed such as: Codec, Simulcast, Absolute Capture Time, Stream Type, Audio, and Echo Cancellation.

Picture-in-picture

This button allows you to toggle picture-in-picture viewing.

Share

The share button opens up a panel that provides links to the viewer for sharing your stream, as well as information about your stream. The share panel provides a link to a hosted viewer that you can share, as well as iFrame code for you to embed the player on your website. More details about this pop-up are described below.

Live stream status

After clicking the Start button you will begin broadcasting. The status and stream name will be displayed in the upper right corner as confirmation.
