Что нового

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. Learn more
#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. Learn more
#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;' Learn more
#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. Learn more
#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. Learn more
#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. Learn more
#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. Learn more
#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. Examples are added to the documentation at https://flussonic.ru/doc/play/webrtc-play#webrtc-examples and https://flussonic.ru/doc/live/webrtc-publish#webrtc-examples
