2019 Q2 summary

Our team has been working on improvements through Q2 of 2019 so let's see what we've accomplished.


Last quarter we've introduced Qosifire live streaming monitoring service. It allows tracking availability and consistency of HLS, RTMP and Icecast live streams. The HLS support was added this quarter, take a look at this page for more details and also watch this video on our channel showing this feature in action. We've also added debugging capabilities for HLS - you can track DTS/PTS timestamps and see their dynamics real-time. Read this article and watch this video for more details.

If you still haven't tried using Qosifire, read why Qosifire might be useful for you and how you can get started with Qosifire, the step-by-step guide to using our quality monitoring control.

Products snapshots

We've added a couple of new pages in our gallery of Softvelum products snapshots which show how you can use our products for building your streaming infrastructure.

Nimble Streamer and more

Nimble Advertizer, our server side ads insertion framework, now has SCTE-35 markers support. So now ads insertion time point can by defined by absolute and relative time as well as SCTE-35 markers.
Also, Nimble Streamer transmuxing engine now supports passthrough of SCTE-35 markers during live streaming.

The Advertizer now also allows using AAC and MP3 containers for advertisement files during audio-only streaming. Take a look at Advertizer tech spec for more details.

We have some updates for SRT users of Nimble Streamer:
  • SRT packet loss for Sender in Listener mode has been fixed. Read this article for more details and upgrade your SRT package.
  • SRT sender "maxbw" parameter is highly useful for preventing from excessive bandwidth usage during lost packets re-transmission. We recommend using it for all streams on sender side. Read this article for more information.
  • SRT "latency" parameters is also very important for re-transmission control and it should be used with "maxbw". Read this article to find out more.

If SRT technology is part of your streaming infrastructure, please read those articles to be up-to-date with latest improvements.

Nimble Streamer now supports RTMP republishing into Limelight Networks, Inc. Realtime Streaming service, take a look at Realtime Streaming Guide for setup details.

We've also improved RTMP to support HEVC for Nimble Streamer and Larix Broadcaster. This is an experimental non-standard feature available in limited number of players.

Starting from May 1st, Facebook deprecates the usage of RTMP and requires RTMP over SSL (RTMPS). And we've glad to confirm our Nimble Streamer and Larix Broadcaster products have full support for RTMPS.

Streaming to social media becomes more and more popular so we've made a couple of articles about that.
We have also collected all documentation for Larix applications in documentation reference page.

Another big update of Larix Broadcaster for iOS and Android and Larix Screencaster for Android is the release of adaptive bitrate (ABR). ABR (adaptive bitrate) is available in 2 modes:
  • Logarithmic descend - gracefully descend from max bitrate down step by step.
  • Ladder ascend - first cut bitrate by 2/3 and increase it back to normal as much as possible.

You can visit Larix website to find out full feature set.

Last but now least, take a look at The State of Streaming Protocols for Q2 2019 with RTMP declining and HLS going up.

We'll keep you updated on our latest features and improvements. Stay tuned for more updates and follow us at Facebook and Twitter to get latest news and updates of our products and services.
