Creating and Managing NextGen Live Events

In this topic you will learn how to create and manage live events using NextGen Live.

Introduction

NextGen Live is Brightcove's next-generation live streaming solution that provides improved reliability, consistency, and scalability. The NextGen Live module can be used to broadcast live events to both desktop and mobile devices with enhanced features and better performance than Legacy Live.

After entering your event information into NextGen Live, you will be provided with streaming endpoint URL that you configure in your encoder.

NextGen Live supports two types of streaming configurations:

  • Event Channels - Created for shorter-length, one-time, or recurring events
  • Linear Channels - Used for delivering 24/7 live content

Prerequisites

Before you can broadcast a NextGen Live event, the following items are required:

  • A Brightcove account with access to NextGen Live
  • A video source to broadcast the event
  • Encoding software (e.g., Telestream Wirecast, Open Broadcaster Software, or hardware encoders)
  • Stable internet connection with sufficient upload bandwidth

Limitations

  • Live broadcasts will experience a 15-30 second delay (can be reduced to 5-10 seconds with low latency mode)
  • Streaming must begin within 30 minutes of starting the channel (default account setting)
  • Some output settings cannot be modified after the channel has been created (use the Edit function to modify configurable options or modify JSON directly)
  • Brightcove scales live streaming capacity dynamically, but creating several channels in a region simultaneously may cause short delays

Billable States

Billing for NextGen Live channels applies to active states:

Active States (billing applies)

  • waiting - Channel is active and waiting for encoder connection
  • connected - Encoder is connected and channel is actively streaming
  • disconnected - Encoder disconnected but channel remains active within reconnect time

Inactive States (billing does not apply)

  • configuring - Channel is being configured and is not active
  • off - Processing state is off and channel is not active
  • starting - Channel is starting and is not active
  • stopping - Channel is stopping and is not active
  • error - Channel encountered an error and is not active
  • finishing - Channel is in the process of finishing streaming and is not active
  • finished - Channel has finished streaming and has been archived

Managing NextGen Live Channels

To access the Live module, log in to Video Cloud Studio and click Live in the left navigation. The Channels page displays all your NextGen Live channels organized into four tabs:

  • All - Displays all channels regardless of state
  • Live - Channels that are currently streaming
  • Standby - Channels that are ready but not actively streaming
  • Archived - Channels that have been archived
NextGen Live Channels page

Each channel displays the following information:

  • Name - Channel name with thumbnail
  • ID - Unique channel identifier
  • Status - Current operational state of the channel (e.g., Off, On, Error)
  • Input Source - Whether or not the encoder is connected (e.g., Disconnected, Connected)
  • Type - Channel type (Event or Linear)
  • Created At - Date and time when the channel was created
  • Input Protocol - Protocol used for the input stream (e.g., RTMP, SRT, RTP)
  • Outputs - Output formats and resolutions generated by the channel (e.g., hls270p, hls360p, hls540p)
  • Region - The geographical region where the channel is hosted (e.g., us-west-2)

You can search for channels using the search bar, and sort results using the Created Date sort button.

Channel Actions

Click a channel row to open the Control Room. From the Control Room header, you can start or stop the channel, open the Embed on Web dialog, open the Create Clips dialog, and access the three-dot menu (⋮) for additional actions (Edit JSON, Copy Channel ID, Archive). See Control Room for details.

Creating a New NextGen Live Event

For complete step-by-step guides to creating and streaming NextGen Live events, see:

To create a new NextGen Live channel, click New Channel at the top right of the Channels page. A 3-step wizard will guide you through the setup.

Step 1: Choose Channel Type

Select the type of channel to create:

  • Event Channel - A single live broadcast with a clear start and end time, ideal for one-time events like webinars, sports, or concerts
  • Linear Channel - A 24/7 always-on live stream designed for continuous, scheduled programming without a defined end
New Channel - Step 1: Choose channel type

Click Next to continue.

Step 2: Channel Configurations

Configure the core settings for your channel:

  • Event Channel Name - Name for the channel (required, max 250 characters). This name will also appear in the Media module if a live media asset is created.

General

  • Create an audio only event - Toggle to live stream audio only over MPEG/TS. This will override some other features.
  • Renditions Profile - Controls the quality and number of live renditions (e.g., Live HD 1080). To manage profiles, go to Admin Settings.
  • Frame Rate - Select frame rate (e.g., 30 fps)
  • Region - Select the region closest to your encoder location (required). The following regions are supported:
    • US East (N. Virginia)
    • US West (Oregon)
    • Asia Pacific (Tokyo)
    • Asia Pacific (Seoul)
    • Asia Pacific (Singapore)
    • Asia Pacific (Sydney)
    • Asia Pacific (Mumbai)
    • Europe (Frankfurt)
    • Europe (Ireland)
  • Input Transport Protocol - Select the protocol for the input stream (required, e.g., SRT, RTMP, RTP)

Input

  • Enable In-Region Redundancy - Adds a backup ingest path in the same region to ensure seamless failover if one input fails
  • SRT Input Passphrase - Enter a passphrase for secure input (only displayed if SRT is selected as the input protocol)

VOD

  • Convert media asset from Live to VOD when complete - Once the live event channel is stopped, the associated media asset will be updated to use the VOD content captured from the event. The channel will then be archived, and it can be accessed through the Media module.

Renditions

A preview of the Video Renditions and Audio Renditions that will be created based on the selected renditions profile is displayed at the bottom of this step.

Important Tips

Understanding Playback Tokens

NextGen Live uses the livePlaybackToken parameter to ensure that playback behavior matches the channel’s configuration.

What is livePlaybackToken?

The livePlaybackToken is a JWT (JSON Web Token) generated by the NextGen Live API. It contains encoded configuration details that determine how playback is delivered for a specific live channel.

This may include settings such as:

  • DVR availability
  • Server-Side Ad Insertion (SSAI)
  • DRM configuration
  • BYO CDN routing

When is livePlaybackToken generated?

A livePlaybackToken is automatically generated for all NextGen Live channels when the channel is published — even if advanced features are not enabled.

Is livePlaybackToken required?

  • Not required for basic live playback without advanced features.
  • Required for channels using advanced features (e.g., DVR, SSAI, DRM, or BYO CDN).
  • Strongly recommended for all custom integrations, even when no advanced features are configured.

While playback may work without the token, always including it ensures:

  • Playback reflects the channel’s intended configuration
  • Consistent behavior across environments
  • Compatibility with future platform enhancements

What happens if the token is omitted?

If the livePlaybackToken is not included in a Playback API request:

  • Playback uses the default live delivery configuration
  • DVR functionality is not available
  • SSAI endpoints are not used (no ad insertion)
  • Channel-specific DRM configuration may not be fully applied
  • BYO CDN routing is not applied (default CDN delivery is used instead)

Playback may still succeed, but it behaves as a standard live stream without advanced channel configuration.

Feature dependency overview

livePlaybackToken Feature Dependency
Feature Requires livePlaybackToken Behavior if Token Is Omitted
Basic Live Playback No Playback works using default live delivery.
DVR Yes No DVR window or seek capability.
SSAI Yes No ad insertion. Playback bypasses SSAI endpoints.
DRM Yes Playback may not fully reflect the channel’s DRM configuration.
BYO CDN Yes Playback uses the default CDN instead of the configured BYO CDN.

Brightcove Player vs Custom Playback API Integrations

Brightcove Player embed codes automatically include the livePlaybackToken.

For custom Playback API integrations:

  • Basic live playback works without the token.
  • Advanced features require the token.
  • Best practice: Always pass the livePlaybackToken when it is available.

Example Playback URL

Using RTMP Outputs

NextGen Live supports RTMP outputs to stream simultaneously to external platforms like Facebook, YouTube, or custom RTMP endpoints.

To configure RTMP outputs:

  1. In the Control Room, scroll to the RTMP Outputs section
  2. Click Add RTMP Output
  3. Enter the RTMP Output URL (destination)
  4. Select the Rendition to send:
    • Choose a specific quality rendition
  5. Click Add to start the RTMP output

Monitoring Your Stream

NextGen Live provides comprehensive monitoring capabilities:

Health Monitoring Dashboard

NextGen Live provides comprehensive health monitoring organized into three main sections:

Ingest Metrics (SRT streams only)

  • Source Bit Rate - Bit rate of the incoming source
  • Source Connected - Connection status (1 = connected, 0 = disconnected)
  • Source Disconnections - Count of source disconnections
  • Source Dropped Packets - Network packets lost during transit
  • Source Packet Loss Percent - Percentage of packets lost

Encoder Metrics

  • Network Traffic In/Out - Rate of network traffic to/from encoder
  • Source Frame Rate - Frame rate in FPS
  • Source Loss Fill Duration - Duration of fill frames used to cover source loss
  • Dropped Frames - Input frames dropped by encoder
  • Output Audio Level - Audio levels in dBFS and LKFS

Packager Metrics

  • Egress Bytes - Bytes successfully sent per request
  • Egress Response Time - Time to process each output request

For more information, see Health Monitoring Dashboards.

NextGen Live Extended Monitoring

Creating Clips

NextGen Live supports creating video clips from your live stream:

  • Clips can be created while streaming or after the event ends
  • Streams are available for clipping for 14 days after the event ends
  • Clips are saved as VOD assets in your Video Cloud library

To create a clip:

  1. In the Control Room, click Create Clip
  2. Set the start and end times for your clip
  3. Enter clip metadata (name, description, tags)
  4. Click Create Clip
NextGen Live Create Clip

Archived Channels

NextGen Live channels can be manually archived and moved to the Archived Channels section of the NextGen Live dashboard. Archiving a channel is a manual action that you perform when you want to remove it from the active channels list.

Notes about archived channels

  • There is no limit on the number of channels that can be archived for an account
  • Once a channel is archived, it will remain in the archived channels list for 30 days although it cannot be started again
  • After 30 days have passed, the archived channel will be automatically removed from the UI

Media Asset Retention

The Live media asset associated with the channel behaves differently depending on whether Live-to-VOD conversion is enabled:

Channels Without Live-to-VOD

  • The Live media asset is not deleted when a channel disappears from the UI after the 30-day archive period
  • The media asset remains available in the Media Module even after the archived channel is removed from the Live module

Channels With Live-to-VOD Enabled

  • When the job is stopped, the Live media asset is overwritten with the Live-to-VOD version
  • The converted VOD asset remains in the Media Module and can be accessed even after the archived channel is removed from the Live module
