We release experimental features to benefit our advanced user community

  • These features may be less reliable and are subject to change

  • We don't provide direct support for these features and don't recommend them for new users


Why might I want to use SRT?

  1. SRT is another method to send your stream to sidelineHD.  You will get the same UP/DOWN messages, the same publishing to FB/YT, and the same clips.
  2. The SRT protocol allows you to use HEVC (H.265) video compression, which sends the same quality video in 1/2 the bandwidth.  (Note: the fastest way to get started with HEVC is to use the Larix Broadcaster app.)
  3. More reliable data transmission in certain situations.

What should I know?

  • SRT works as any other sidelineHD advanced camera source.
  • You will get UP / DOWN text messages as before.

Creating your SRT URL:

1/ Go to your STREAMING tab.

2/ If you don't already have an advanced camera, create one.  If your advanced camera is not a Mevo, click on "Edit camera" to change camera type to Mevo. 

3/ Get your stream key by clicking on Camera info >> Manually enter RTMP.  Copy the Stream Key field.

Your SRT URL is:

srt://g002.sideline-ingest.com:50000?streamid=shd03/{Stream Key}

(in the above, 0="zero")

For example, let's say your stream key is: s03-wwww-xxxx-yyyy-zzzz.  Your SRT URL would then be:


In some situations, you may need to use this longer URL:

srt://g002.sideline-ingest.com:50000?maxbw=625000&latency=3000&streamid=shd03/{Stream Key}

NOTE: URL parameters are subject to change

SRT parameters / notes:

  • We recommend H.265 (HEVC).  There are easier ways to send us H.264.
  • Do not exceed 4mbit (maxbw = 625000).
  • Do not exceed 1080p.
  • For time-sync parity, we currently force a latency = 3000ms.
