What's New

Flussonic Media Server

• #1364 (new) (Flussonic) The NIT is now sent to CBR MPTS output streams.
• #8936 (new) (Flussonic) The new option 'interlace' was added to the transcoder to prepare video for broadcasting to cable TV networks.
• #9256 (new) (Flussonic) If you use authorization with tokens (auth securetoken://), you can skip checking the client's IP address. Flussonic can generate tokens without taking IP addresses into account. This is useful if clients' IP addresses are not known.
• #10441 (new) (Flussonic) Ingesting video and audio from the Stream Labs SDI cards that support Video4Linux. Specify the source as 'url v4l2:// video_device=/dev/video1 audio_device=plughw:1,1;'
• #11032 (new) (Flussonic) achieved full DVB compliance in MPTS output: 1 and 2 level of tr101290 are green
• #11145 (new) (Flussonic) Flussonic can pass SCTE35 markers from input MPEG-TS to output MPEG-TS. Processing of SCTE35 markers was re-worked and the option 'scte35=true' now works.
• #11967 (new) (Flussonic) We are working on enhanced infrastructure for deploying help buttons to the UI.
• #12085 (new) (Flussonic) The CPU transcoder now adapts seamlessly (without losing any frames) to the change of the stream's media information, and the option 'seamless=true' is no longer necessary for the CPU transcoder because this is the default behavior now. The option 'seamless=false' can still be used to disable smooth adaptation.
• #12086 (new) (Flussonic) We have completely reworked the system of sending UDP multicast with a constant bitrate. Flussonic can now maintain the HRD buffer between zero and one second during CBR MPEG-TS encoding, thus making CBR possible.
• #12210 (new) (Flussonic) Decklink duplex mode that allows you to select input or output direction of an SDI card.
• #12228 (new) (Flussonic) The hardware transcoder on Nvidia NVENC now adapts seamlessly (without losing any frames) to the change of the stream's media information, and the option 'seamless=true' is no longer necessary for the NVENC transcoder because this is the default behavior now.
• #12295 (new) (Flussonic) HEVC is now supported in outcoming MPTS streams via UDP2.
• #2983 (improved) (Flussonic) now can produce MPEG-TS that VLC can play without "playback way too early" warnings
• #11413 (improved) (Flussonic) now can handle DVB subtitles that appear word-by-word during broadcasting
• #11667 (improved) (Flussonic) can properly teardown keepalive connection to broken server that doesn't send body fully
• #11804 (improved) (Flussonic) Flussonic can publish from admin page using password from config
• #11908 (improved) (Flussonic) now can disconnect while pushing to upstream server when stream doesn't have any frames anymore
• #11990 (improved) (Flussonic) Using IPv6 for video delivery.
• #12398 (improved) (Flussonic) PAT/PMT frequency no longer depend upon the bitrate.

Flussonic Coder

• #12083 (new) (Сoder) The support for Nvidia SDK 32.4.2.

The player

• #10012 (new) (WebRTC player) Now our WebRTC publisher code will automatically detect silence, lost microphone, and will produce uninterruptable smooth output.
• #12276 (new) (Player) To enable a pause before playing on-demand streams in the DVR player (/embed.html?dvr=true) use 'autoplay' or 'autoPlay'.
• #12238 (improved) (Player) MSE-LD now properly switches when media info changes
• #12079 (improved) (Player) We published a new demo app at github.com/flussonic that imports our library to demonstrate the work of the WebRTC player.
