How to Enable Adaptive Bitrate (ABR) in Castr
Castr supports adaptive bitrate streaming for our HTML5 players, available only in our All-in-one plans.
Here's how to enable it on the Video Settings tab:
Go to an All in One Stream project.
Click on Video Settings > Player Functions
Toggle on the 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.
Customize Your Live Transcoding Settings
The default settings for Frames per second (FPS) when you enable Adaptive bitrate streaming is 30 FPS. If you are streaming at 60 FPS, you can change it in the Advanced 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 the user’s bandwidth and device capacity.
In ABR, videos are transcoded real-time and 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.
