Flussonic Media Server 22.08

Flussonic Media Server 22.08 has been released.

DVR catch up link now combines two HLS types: EVENT and VOD. Flussonic automatically finishes EVENT links: it will return EVENT if "now" marker points into specified interval and return VOD when it comes into the past. You can insert one universal link into your website or application instead of updating it after event.

It's more convenient to run Flussonic in Kubernetes, we have prepared several improvements: Flussonic can store license files in k8s secret storage, get configuration from system environment, read configuration from includes /etc/flussonic/flussonic.conf.d/, new monitoring endpoints (liveness, readiness) are added. Please share your experience with Flussonic in Kubernetes: support@flussonic.com.

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