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
• 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• finished - Channel has finished streaming and has been archived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 Events

The NextGen Live interface displays channels organized by their current state:

• Channels - Channels that are created and active
• Archived Channels - Channels that have finished streaming and are archived

Each channel displays the following information:

• Name - Channel name and Job ID for identification
• Status - Current operational state of the channel (e.g., Off, On, Error)
• Input Source - Whether or not encoder is 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, etc.)
• 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)

Configuring Advanced Options

NextGen Live provides several advanced configuration options:

Digital Rights Management (DRM)

Configure DRM encryption for your live stream:

• Enable All Encryptions - Enable all available DRM encryptions
• Widevine - Google Widevine DRM encryption
• FairPlay - Apple FairPlay DRM encryption
• PlayReady - Microsoft PlayReady DRM encryption
• License Key Protection - Additional license key protection (may require account enablement)

RTMP Output

Configure RTMP outputs to stream simultaneously to external platforms:

• RTMP Output URL - Destination URL for RTMP output (required)
• Video Rendition - Select video quality for RTMP output (required)
• Audio Rendition - Select audio quality for RTMP output (required)

Redundancy

Configure redundancy settings for improved reliability:

• Enable In-Region Redundancy - Enable redundancy within the same region for failover protection. In case one of the streams fails or encoder goes down, the other stream will automatically take over.

Advanced Options

Configure advanced streaming features:

• SCTE 35 Passthrough - Pass through SCTE 35 signals for ad insertion
• Low Latency (LL-HLS) - Use Low-Latency HLS protocol for 5-10 second end-to-end latency
• Ingest IP Whitelist - Restrict input to specific IP addresses for security
• Caption Languages - Configure supported caption languages

DVR Window

Configure DVR functionality for live stream playback:

• DVR Window - Enable DVR functionality
• Time - Set the time in seconds to keep in the live DVR manifest (maximum 28,800 seconds/8 hours)

Captions

NextGen Live supports closed captions with enhanced compatibility across platforms:

Supported Caption Formats

• EIA-608 - Standard closed caption format
• EIA-708 - Digital television closed caption format

Caption Configuration

Configure caption languages for maximum compatibility:

• Caption Languages - Specify up to 4 caption languages using 3-letter ISO 639-2 codes
• Embedded Captions - Captions embedded in the input stream will be passed through by default
• Android Compatibility - Language codes are essential for Android devices to properly display captions

Caption Language Examples

Common language codes for captions:

• eng - English
• spa - Spanish
• fra - French

API Configuration

When creating a NextGen Live channel via API, configure captions in the job payload:

{
  "outputs": {
    "caption": [
      {
        "type": "embedded_closed_caption",
        "passthrough": true,
        "language_code": "eng"
      },
      {
        "type": "embedded_closed_caption", 
        "passthrough": true,
        "language_code": "spa"
      }
    ]
  }
}

This example configures two caption languages (English and Spanish) that will be passed through from the input stream with proper language identification.

Important Tips

Understanding Playback Tokens

NextGen Live uses livePlaybackToken parameters to provide enhanced playback functionality and ensure consistent streaming behavior.

What is livePlaybackToken?

The livePlaybackToken is a JWT (JSON Web Token) that contains configuration information for how the Brightcove platform should handle your live stream. This includes settings for DVR, SSAI, CDN routing, and other advanced features.

When is livePlaybackToken used?

NextGen Live automatically generates and includes livePlaybackToken in playback URLs for:

• All NextGen Live channels (regardless of features enabled)
• DVR-enabled streams
• SSAI-enabled streams
• BYO CDN configurations
• DRM-protected content

Example Playback URLs

Simple NextGen Live channel:

https://players.brightcove.net/2048251699001/default_default/index.html?videoId=6378332368112&livePlaybackToken=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJtbiI6InBsYXlsaXN0IiwiaXNzIjoiYmxpdmUtcGxheWJhY2stbWFuYWdlbWVudC1hcGkiLCJzdWIiOiJwbGF5YmFja3Rva2VuIiwiYXVkIjpbIjIwNDgyNTE2OTkwMDEiXSwianRpIjoiNjM3ODMzMjM2ODExMiJ9.PhV0KkKfE6ryO5hieDnHyTieVKJkDszGvckIzYYal-c

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
