Flussonic Media Server

  • #7921 (new) (Flussonic) Flussonic no longer has the default login and password. You will need to specify your own login and password during the installation. Learn more
  • #9780 (new) (Flussonic) Flussoniс now can read XMLTV EPG and send it to MPTS output as EIT. The ‘transponder’ directive has a new option, ‘eit’, for configuring the EIT EPG output. Learn more
  • #11422 (new) (Flussonic) Three fields for monitoring incoming streams in API ‘/flussonic/api/input_media_info/STREAM_NAME’: last_gop, gop_size, and avg_fps. Usage example: to identify streams that will cause buffering when being published to social networks because they do not meet the key frame interval requirement. Learn more

The players

  • #13349 (new) (Player) The MSE player now supports new controls that are found in usual desktop players, such as the the pause, resume, or unmute. The controls are part of MediaElement, which can be attached to the player as a separate part after initializing. The event onMediaAttached indicates that the player has been attached to the HTTP element and therefore is ready to start playing video. The events onPause and onResume are used for adding player’s reaction to these events. Learn more
  • #12523 (improved) (Player) Publishing and playing audio-only content via WebRTC is supported now (and this makes it possible to create WebRTC audio podcasts). In your code of the publishing app add to publisher’s ‘constraints’ the line ‘video: false’. Along the way, the mute function was added to the publisher class (publisher.mute()). Learn more at https://www.npmjs.com/package/@flussonic/flussonic-webrtc-player and in the documentation.
