Get Started

Media Acceleration Live Broadcast delivers live video through the CDNetworks content delivery network (CDN). This guide explains how to create live streaming domains, configure DNS, and test ingest and playback.

Plan your live streaming domains

Live streaming involves a source, a CDN, and viewers. The source provides a stream, CDNetworks receives or retrieves it, and viewers request it through a compatible player.

The following diagram shows how a stream enters CDNetworks and reaches viewers.

Choose the domains and stream ingest mode that match your workflow:

An ingest domain receives streams from broadcasters or encoders. A delivery domain provides playback URLs for viewers. For Publisher Ingest, create the ingest domain first so you can select it when creating the delivery domain.

Add a live streaming domain

1. Go to Media Acceleration Live Broadcast > Configuration.
2. Choose New Domain.
3. Configure the basic information.

4. Configure the domain for the selected role:
   • Ingest: Enter the domain name in Ingest Domain.
   • Delivery: Select the Stream Ingest Mode and complete the corresponding settings below.

For Origin Pull:

Use Add for another domain row or Bulk Add (Same Origin, Multiple Domains) for domains that share an origin. Batch Import is also available.

For Publisher Ingest:

5. Configure the remaining domain settings.

6. In Acceleration Configuration, choose how to create the configuration:
   • Custom Configuration: Start with the default configuration and adjust settings after creating the domain.
   • Copy Configuration from Existing Domain: Select an existing domain to copy its configuration.
7. Optional: In Associate Certificate, select an available certificate if the domain will use HTTPS. If no certificate is available, complete certificate setup before testing HTTPS playback.
8. Review the settings and choose Submit.

The new domain appears in the domain list with an assigned CNAME target.

Configure DNS

Complete these steps for each ingest and delivery domain:

1. Copy its assigned CNAME target from the domain list.
2. At your DNS provider, add a CNAME record whose name is your ingest or delivery domain and whose target is the assigned CDNetworks CNAME.
3. Use a DNS lookup tool to confirm that the record resolves to the assigned target. Allow time for DNS changes to take effect.

Use your own ingest and delivery domain names in stream URLs. The assigned CNAME target is for DNS configuration.

Example: Push a stream and play it back

This example uses Publisher Ingest with the following values:

Before testing, confirm that both domains resolve correctly, the delivery domain is associated with the ingest domain, and the application name and playback protocol are allowed. The HTTPS examples below also require a valid certificate for the delivery domain.

In OBS Studio or another compatible encoder, configure custom RTMP output:

• Server: rtmp://push.example.com/live
• Stream Key: demo

Start streaming. The encoder publishes the stream as live/demo. While the encoder is sending data, open a compatible player and test a playback URL for an enabled protocol:

Replace the example values with your own. If authentication is enabled, include the required authentication parameters in the ingest and playback URLs as configured for each domain.

If ingest or playback fails, see Live Streaming Troubleshooting.
