Flussonic Media Server 22.04

Flussonic Media Server 22.04 has been released.

Added split_channel option to transcoder configuration. This option allows to split each audio track with multiple channels into several mono tracks. It is suitable for event streaming when you have to pack different audio content (different languages, music) into a single track.

Start track for [WebRTC adaptive bitrate] playback can now be selected for each playback session instead of stream configuration. It allows quality personalization for each client.

[WebRTC] player now displays only the available resolutions supported by the camera. It is suitable for scenarios when a user needs to manually set, for example, the highest or lowest possible quality of the video that he publishes.
