SRT Alliance Announces the Addition of the SRT Low Latency Protocol to Open Broadcaster Software’s OBS Studio

OBS Studio adds SRT (Secure Reliable Transport) as an alternative to RTMP streaming

Montreal, Canada(04 Apr 2019)

The SRT Alliance, supporting the SRT Open Source Project, announces that the SRT streaming protocol is being added to Open Broadcaster Software’s OBS Studio – a free and open source software for video recording and live streaming widely adopted within the streaming industry.

SRT is an open-source protocol, developed by Haivision, which allows broadcasters and streamers to deliver high-quality, low-latency streams across the public internet. SRT is fast becoming the de facto low-latency video streaming standard in the broadcast and streaming industries.

OBS Studio is a free open source tool that creators use to broadcast their content to the world through livestreams and recordings. OBS Studio allows users to capture video from a variety of sources, such as cameras and computer screens, and composite them into professional productions that are used to entertain, teach, and inspire. It has formed the bedrock for creators to launch entire careers broadcasting to their audiences on platforms like Twitch, YouTube, Mixer, Facebook and more.

SRT has also been integrated within these other popular open source initiatives:

  • VideoLAN’s VLC multimedia player, encoder, and streamer
  • GStreamer multimedia framework
  • FFmpeg cross-platform solution to record, convert and stream audio and video
  • Libav open source audio and video processing tools
  • Wireshark the world’s foremost and widely-used network protocol analyzer

Since SRT became open source at NAB 2017, over 200 companies, including Microsoft, Comcast, Bitmovin, Limelight, Brightcove, Wowza, and Kaltura, have shown their support for the emerging standard by joining the SRT Alliance. For a current list of SRT Alliance members see srtalliance.org/members.

At NAB 2019, the SRT Alliance is hosting a free-to-attend SRT Technical Panel featuring developers from Bitmovin, Deluxe, Gogo, Haivision, and Wowza.
