How to Enable Adaptive Bitrate (ABR) in Castr

Castr supports adaptive bitrate streaming for our HTML5 players. Here's how to enable it in the Video Settings Page:

  1. Go to a All in One Stream project

  2. Click on Video Settings 

  3. Toggle Enable Adaptive Bitrate Transcoding button

The stream is now transcoded and delivered in multiple bitrates from Castr. 

Note: It's highly recommended to set the incoming bitrate of the stream to 4000 kbps to 5000 kbps for better performance.

How to Get Custom Live Transcoding Settings

What is Adaptive Bitrate Streaming?

Adaptive bitrate (ABR) is a video streaming technology that helps to deliver video in the highest quality possible based on user’s bandwidth and device capacity.

In ABR, videos are transcoded real-time compressed at a number of different rates, We transcode one single video source to multiple versions of different bitrates.

If your internet bandwidth doesn’t allow for streaming the 4000 Kbps version, you can still view the same video at a lower bitrate, for example, 2,500 Kbps.
