SRT playback support in Larix Player

SRT became a popular transport protocol for live streams secure delivery over unreliable network. Softvelum team has been an active contributor to SRT open source community being part of SRT Alliance.

Softvelum products lead products have full support for SRT:

Now we introduce SRT playback support in Larix Player for Android and Larix Player for iOS.
SLDP Player for HTML5 does not support SRT yet unfortunately.

SRT playback is available in all 3 modes: Pull (Caller), Listen and Rendezvous.

Mobile Larix Players provide low latency consumption of SLDP, RTMP, Icecast, HLS and MPEG-DASH and adding SRT gives more flexibility, robustness and reliability for end-user last-mile playback.

You can get Larix Player free app in Google Play and AppStore.

If you want to obtained SRT via SRT Pull mode, you need to make sure your source media server or streaming service has SRT Listen mode enabled for the output stream. Read SRT setup description for Nimble Streamer to see how it can be set up there.

The player setup is easy, just open the application, add new connection and enter your stream with srt:// protocol prefix.

The Player supports the following SRT parameters and provides respective fields:
  • passphrase and pbkeylen;
  • latency and maxbw - read this article for more details about their usage;
  • streamid in case your media source supports it.
If you'd like to use Listen or Rendezvous modes, they are set up in a similar way.

Once you save it and tap on it, it will connect to your server and will start playing the stream.

Let us know if you have any questions or suggestions regarding Larix Player.


  1. Hi , I am trying Larix Broadcaster ( downloaded from Android play store sep23 version), to broadcast to a listener (gstreamer) on my laptop. both the mobile and the laptop are on the same WiFi network. I dont see any UDP-SRT packets on my laptop, not even the initial handshake. Is there something fundamentally wrong with the way am setting it up ?
    Thanks for any insight.
