More detailed:

Before start it asks you what is server url you would use.For example: if Proxy Addon is runngin then Link Generator suggests using it.


SDI Out Addon

Totally new SDI Out Addon. Now it supports multichannel outputs.
Also it uses SRT-->SDI chain instead SRT-->NDI-->SDI in previous version. It means performance and quality optimization.
This addon included directly inside server and you don't need separate install it.

imagethe addon supports output to file also

Support for Larix Talkback

Last version of Larix Broadcaster app offer Talkback feature: it allows play audio feed from Studio.We added support this feature to our server.Just use same SRT params for Talkback settings in Larix Broadcaster with only one update: add #talkback suffix to stream id.

imagesettings for Talkback connection

It's useful for Anroid users because Stream To Studio(with video/audio feedback) exists only for iOS.

Watchdog for buffer

We added new field called “Critical Delay”. The server resets buffers when the video buffer exceeds this value.
Recommended value is "Start Delay" plus 500ms (or more). Set it to zero if you don't need watchdog.


Conference Addon

This addon created to make SRT-conference easy.Every participant will get:

  • common video feed
  • mix-minus audio feed

No heavy setup for CrossLine and audio - this addon does this automatically.Also it allows use NDI feed as master (from vMix or Tricaster for example).

This apps can be used by participants:

  • RemoteExpert (Windows)
  • SRTStreamer (Windows)
  • Stream to Studio (iOS)
  • Larix Broadcaster (version with Talkback) (iOS & Android)
  • vMix (Windows)
  • OBS (Windows & macOS)

notes: how to play feedback in vMix or OBS see here


This addon marked as BETA because we are still working on it. We will be glad any feedback about it.
