Hi, The SRT library has been made Open Source in April 2017, but was used before in Haivision products since 2013. It is used in 100s of mission critical installation (medical, sports, broadcast, military) worldwide and its reliability has been proven. Since its Open Source, 100 organizations have joined the SRT Alliance (https://www.srtalliance.org/) in order to create a new ecosystem for broadcast quality streaming over the public internet, which wasnt available as Open Source up to that point and only offered as commercial solutions by very few specialized companies. Meanwhile many organizations including the EBU (Eurovision), Wowza, Matrox and many more have SRT Ready solutions. SRT has been integrated into VLC and GStreamer. The SRT Alliance is working with the video services forum, who recommends standards to SMPTE, towards a standardization of the protocol. Many architectures in the broadcast industry are using either libav or ffmpeg and are asking when they will be able to utilize SRT though these known media libraries. I understand the name is not optimal, but when it was initially created in 2013 unfortunately nobody thought about taken it Open Source due to the typical industry mindset at that time.
