Note

This feature is currently in Public Preview.

SRT-In enables meeting and event organizers to produce their meetings and events directly from an external hardware or software-based encoder using the Secure Reliable Transport (SRT) protocol.

As an admin, you can use meeting policies to turn on SRT-In for meeting and event organizers. Organizers with this policy can access the SRT link and key that they need to start streaming from the encoder through their Meeting options. To learn more about encoders, see Using an encoder for live event streaming with Microsoft Teams.

The incoming SRT feed must deliver:

  • H.264 Advanced Video Coding (AVC) and H.265 High Efficiency Video Coding (HEVC)

  • Constant Bitrate (CBR) and Variable Bitrate (VBR) for 1080p

  • Frame rate of least 29.97 fps or 30 fps or higher

  • Square Pixel Aspect Ratio (PAR)

SRT ingest endpoints

As part of the network connectivity principles, make sure that the Microsoft 365 endpoints are reachable as defined in Microsoft 365 URLs and IP address ranges.

Verify that you also have the following domain and port:

Domain: *.rtmpingest.mcr.teams.cloud.microsoft
Port: 49891 (SRT)
