Flussonic Media Server 22.10

Flussonic Media Server 22.10 has been released.

Flussonic is now fully compatible with the Kubernetes environment. Use our guide, and you will get a working server ready for receiving streams with a few clicks. We provide examples of running Flussonic both on DigitalOcean and in Docker Desktop. Also find an example of creating a publishing cluster in our public git repository. Please share your experience of using Flussonic in Kubernetes with us at support@flussonic.com.

The quality of experience in real-time communication will greatly improve – in this Flussonic version we enhanced the quality of playback over WebRTC/UDP.

Check the full list of improvements and fixes below and get your servers upgraded as soon as possible.
