Redundant Channels

In this topic, you will learn how to create Redundant Channels. Redundant Channels allow you to send two contribution sources with automatic failover for uninterrupted, reliable playback.

Enabling Redundant Channels

While Creating a New Channel, scroll down to the Redundancy section and select Enable In-Region Redundancy.

After you click Save, Scroll down to the Live Channel Details to see your Input URLs.

You can stream to both endpoints to create live-stream redundancy and ensure uninterrupted playback.

Monitoring

Click the Health Monitoring tab below the preview player to view monitoring information for both streams simultaneously.

Monitoring information is available while a channel is in progress and for up to 1 hour after the channel ends.

Enable Low-Latency Redundant Streaming

This topic shows how to create a low-latency event with in-region redundancy in Live.

Creating an Event Channel

  • In Studio, open the Live module.
  • While creating a new channel, select Enable In-Region Redundancy under the Redundancy section.
  • Scroll down to the Low latency section.
    • Low latency setting screenshot
  • Click Create Event.
  • After the event is created, note the SRT/RTMP Ingest URLs for both primary and backup feeds.

Configure ffmpeg for low latency

  • In the terminal, enter the following command (replace input.mp4 with your source): 
    ffmpeg -re -i input.mp4 -c:v libx264 -profile:v baseline -level 3.0 -preset ultrafast -g 30 -keyint_min 30 -sc_threshold 0 -r 30 -x264opts "no-scenecut" -c:a aac -b:a 128k -f mpegts "srt://0123456789-1.ingest.live.brightcove.com:5000?pkt_size=1316&latency=200"
