Flussonic Media Server v.23.07

We're excited to announce the release of Flussonic Media Server 23.07. This update brings significant enhancements to the Admin UI, improving push status display, audio track configuration, and failover file transcoding. The DVR Player has been refined with bug fixes, addressing logo display issues, playback during input unavailability, and WebRTC WHEP session restarts. A notable addition is the episode-based DVR mechanism, offering flexibility, scalability, and fault tolerance. The update also introduces passthrough support for time_signal markers, enabling precise ad insertion. Furthermore, logging and DVR index optimization result in clearer logs and reduced storage requirements.
