Что нового

Flussonic Media Server

  • #10668 (new) (Flussonic) Flussonic can pass subtitles in WebVTT to output DASH streams. Before, only TTML subtitles were supported for DASH. Подробнее
  • #10877 (new) (Flussonic) Flussonic ingests raw frames from Decklink cards now without transcoding, and then transcodes them as specified in the ’transcoder’ directive. This way, in the configuration with several stream sources and the transcoder, video from Decklink is transcoded only once. The ’enc’ option used with ‘url decklink://’ was deprecated, so use the ’transcoder’ directive. The UI support the new settings making it more convenient to configure Decklink streams. Подробнее
  • #10439 (new) (Flussonic UI) The new DVR tab with global DVR settings was added to Config.
  • #11460 (new) (Flussonic) For devices that cannot play DASH with multi-period timeline, such as LG TVs on WebOS, we designed a single-period manifest enabling you to play DASH on that devices. Add ‘period=mono’ to the URL as follows: ‘http://HOST/STREAM/archive-TIME-DURATION.mpd?period=mono’ and ‘http://HOST/STREAM/archive-TIME-now.mpd?period=mono’. Подробнее
  • #11462 (new) (Flussonic) It is possible now to create streams in an external system and provision stream settings to Flussonic by request. Flussonic has a new plugin ‘config_remote’ that directs requests for streams to a custom backend that returns the settings of a requested stream. If there are thousands of published streams and the configuration file is frequently updated, this measure makes your service work without delays. Stream configurations are dynamically updated from this external system.
  • #11505 (new) (Flussonic) We add to Flussonic the MPEG-TS constant bitrate generator that produces per-PID strict CBR.
  • #11573 (new) (Flussonic) You can enable logging of HTTP requests to Flussonic in the UI section Config by selecting the check box ‘Log requests’. This sets the server’s global option ’logrequests true’. This log shows which manifests and segments are sent to players, and the player’s IP address and session.
  • #11656 (new) (Flussonic) New transcoder options: ‘rc_method=cbr|vbr’ (that sets constant or variable bitrate) and ‘qp_range=QPmin:QPmax’ (or ‘qp_range=QPminI:QPmaxI:QPminP:QPmaxP:QPminB:QPmaxB’), which sets the range of the quantization parameter.
  • #11164 (improved) (Flussonic) Important! Aspect(X) and Aspect(Y) are no longer supported. Please use SAR instead. SAR values greater than 9 no longer cause transcoder failure.
  • #11783 (new) (Flussonic) Playing live MSS streams with DRM (such as PlayReady) on LG WebOS3 is now supported (as well as on some Samsung and Phillips models).
  • #11794 (improved) (Flussonic) The bitrate of PIDs in output MPEG-TS MPTS has become smoother.
  • #11869 (improved) (Flussonic UI) The UI for configuring authorization backends was re-worked to support all settings.
  • #11904 (new) (Flussonic) You can configure PIDs in the MPTS transponder that you add in the ’transponder’ directive.
  • #11911 (new) (Flussonic) Playing live MSS streams with DRM (such as PlayReady) on LG WebOS4 and WebOS5 is now supported.
  • #11919 (new) (Flussonic) The MPTS transponder now can reload configuration.
  • #12025 (improved) (Flussonic) The MPEG-TS’s program map table has the ‘stream_type’ field. We have changed it from 4 to 3 to support MPEG-1 Layer 2 audio (mp2a) (stream_type = 3).

Flussonic Coder

  • #11713 (new) (Coder) The transcoders’ metrics are collected separately for each transcoder and can be obtained in Pulse via custom queries, for example, ‘dec_timnig{media=stream_name}’. The metrics are ‘dec_timing’, ’enc_timing’, ‘bitstream_err_count’ (errors in an input stream), ‘dec_err_count’ (errors when decoding), ’encoders’ (the number of output qualities), ‘fps_in’, ‘fps_out’, ‘mqlen’ (queue size of the transcoder process).
  • #11886 (new) (Coder) We are further preparing the transition to the seamless-only mode where the transcoder does not drop frames when the stream source changes.

The player

  • #5118 (new) (Player) You can play live and VOD streams on LG TVs, which have WebOS, by using the Flussonic’s embed.html player in the browser. For WebOS, the player uses DASH.
