Flussonic 19.09 was released.

What's New

Flussonic Media Server

• #6567 (new) [Flussonic] Flussonic is available as a Docker image: docker run --rm -e LICENSE_KEY="l4|...." -p 80 -p 443 flussonic/flussonic
• #7517 (new) [Flussonic] You can configure bitrate when transcoding from Opus to AAC, with the option 'aac_ab' that sets the bitrate in output AAC (the default is 'aac_ab=32k').
• #7842 (new) [Flussonic] Flussonic can recognize HE-AAC codec features in AAC frames and can read HE-AAC version markers.
• #9134 (new) [Flussonic] The UI supports the new push representation.
• #9149 (improved) [Flussonic] Audio codecs that are not supported by browsers are no longer packed for the MSE-LD protocol to be played in our MSE player.
• #7369 (improved) [Flussonic] In some cases, Flussonic can consume a lot of CPU at launch. Now Flussonic shows a warning in the UI that the system has 'Not optimal scaling_governor profile set' so that you could change it to 'performance' for each CPU and prevent excessive CPU consumption.
• #9150 (improved) [Flussonic] Streams published via RTMP from Flash players can be configured for playback in browsers via WebRTC or MSE-LD. Add the option 'output_audio=keep|add_aac|aac' to output stream configuration.
• #8283 (improved) [Flussonic] The new option expires that you add to DRM settings allows you to set the interval for key rotation.
• #8734 (improved) [Flussonic] You can configure global DVR RAID options in the Flussonic UI and assign global DVR configurations to streams.
• #8891 (improved) [Flussonic] The source switching mechanism was reworked to minimize lags. Flussonic can accept frames from several sources and it will not switch from the lower-priority source until it receives frames from a higher-priority source.
• #9096 (improved) [Flussonic] Switching from one source to another in a cluster was optimized.
