Introducing SLDP

Low latency has been a trending issue during past years as Flash and RTMP are being deprecated by the industry. So media streaming companies are trying different options to handle real-time video and audio delivery. Our company are getting requests about providing the solution which might address this concern.

We introduce SLDP: Softvelum Low Delay Protocol.

It's a last-mile delivery protocol to end-user devices at multiple platforms. SLDP is based on WebSockets.

It's basic capabilities are:
  • Sub-second delay between origin and player.
  • Codec-agnostic to play whatever your end-user platform has - H.264, VP9, HEVC.
  • ABR support with switching channels taking just a GOP time and each channel may use its own codec.
  • HTTP and HTTPS on top of TCP: use it with any network settings.
SLDP HTML5 playback is available in MSE and MMS browsers via light-weight JavaScript player. It works fine in Chrome, Firefox, Safari, Chromium and Microsoft Edge on the hardware platforms which have that support, like PC, Mac, iOS (iPad and iPhone), Android.


As for server side, at the moment SLDP transmission is available Nimble Streamer. It's just another protocol output supported by our server. Any supported live protocols can be used as an input.

Feel free to try it in action right now by installing or upgrading your Nimble instance and selecting SLDP in live streams settings besides existing methods.

Please visit SLDP website and contact us in case of any questions as we're moving on with SLDP so your feedback is appreciated.

    Great initiative, I've been testing it and so far seems good. Looking forward to using in production when it's a little more mature.

    Is this now stable enough for production?

      Yes, it's being used by dozens of our customers successfully. We'll soon release State of Streaming Protocols for Q4 and entire year of 2017 - you'll see it there.
