Flussonic version 20.02

Flussonic Media Server 20.02 was released.

What’s New

  • #4252 (new) [Flussonic] The short notation for specifying output protocols for a stream on one line in the configuration file: by using the new ‘protocols’ option. Learn more
  • #9143 (new) [Flussonic] The support for Blackmagic Decklink Quad2 cards: the ‘duplex’ option was added for you to tell Flussonic whether your card uses 4 or 8 SDI ports (‘url decklink://0 duplex=full|half’, ‘full’ allows using 4 ports, ‘half’ - all 8 ports; set this option for devices 0 - 3).
  • #10337 (new) [Flussonic] Flussonic can now deinterlace progressive streams (decklink://) by using the yadif method (Learn more), and also use yadif when transcoding on Nvidia NVENC (Learn more), thus achieving better quality of output video. Add ‘deinterlace=yadif’ to a stream’s settings.
  • #10443 (new) [Flussonic] The transcoder processes the parameters ‘size’, ‘aspect’, ‘force_original_aspect_ratio’, and ‘crop’ in a new way. The main change is that ‘size’ now means the size of a player window on the screen rather than size in pixels. The strategy of resizing (crop, fit, scale) was added. So the size can be set in one of the ways: size=WxH:fit:#ААFFEE, size=WxH:crop, or size=WxH:scale. The parameter ‘aspect’ means SAR now.
  • #10532 (new) [Flussonic] Parsing WebRTC player statistics for providing QoE measurement.
  • #10533 (new) [Flussonic] The initial support for SDI output was added (Decklink). To the stream settings add a line like the following: ‘push decklink://0 size=720x576 fps=50 volume=0.01 deinterlace=true’. Learn more
  • #10675 (new) [Flussonic UI] The streams’ Overview page was reworked to provide more information and convenience.
  • #8015 (new) [Flussonic UI] Now you can specify Program ID in stream settings > Output > Additional options > MPEG-TS specific.
  • #9560 (improved) [Flussonic] You can configure Flussonic to protect the file system from accessing from the Flussonic UI. For this, use the environment variable FLUSSONIC_DATAPATH to specify the directory to which VOD, DVR, and cache locations should be limited.
  • #9723 (improved) [Flussonic] On the DRM page you can now specify the encryption key rotation interval (the ‘expires’ option).
  • #9746 (improved) [Flussonic] For all supported DRM systems, Flussonic now rotates a DRM key once in 10 minutes by default. Use the option ‘expires’ to set a different interval for key rotation. Learn more
  • #10503 (improved) [Flussonic] We have prevented the situation when Flussonic might stop responding if it fails to load license info. The server will try to reboot and obtain license info each minute while showing the UI page for entering a license key.
