The Unified Streaming Platform supports all resolutions up to 4K, and even higher resolutions should not pose any immediate problems either. However, do note that to successfully deliver 4K to Apple devices using HLS, using fMP4 HLS is required (so, not HLS TS).

Supported Encoders

Our software is compatible with the output of encoders from a wide variety of vendors, like Ateme, Beamr, Cisco, AWS Elemental, Harmonic, Media Excel and Telestream.

For Live, all encoders that produce output according to interface 1 of the Interface 1 of the DASH-IF Live Media Ingest specification are supported.

For VOD, the basic requirement is that your audio and video content is contained in ISO BMFF (i.e., (f)MP4) with GOP alignment across bitrates and all video fragments starting with an IDR frame. For text and timed metadata, additional formats are supported: Supported Ingest. Also, a HLS stream that adheres to a strict set of requirements may be used as ingest for Unified Origin for VOD (although this is not recommended): Using HTTP Live Streaming (HLS) as source.

Furthermore, content should be encoded in one of the Supported Codecs for both Live and VOD.

System Requirements

Supported Operating Systems

OS Version
Alpine 3
CentOS 7
Ubuntu 18/20
Windows Server 2016

Redhat and Oracle Linux are possible as well, based on the CentOS build.

Supported Webservers

Webserver Version OS Comment
Apache 2.4 Windows, Linux VOD & LIVE



Going forward, we limit our support for new installations to Apache and recommend a switch to Apache for setups currently running on NGINX. We will continue to support NGINX for existing customers for both VOD and Live, but we won't work on feature development for it. In short, support for NGINX should be considered deprecated. Do note that this does not affect our recommendations of using NGINX in other parts of your video streaming setup, such as for (shield) caching.

End Of Support

Unified Streaming Platform is supported for various Operating Systems. For each OS, we aim to support at least two major (LTS) versions: the latest as well as the previous release. Below table shows an overview of sunset dates for each target platform.

To avoid running our software on an unsupported platform, we recommend using a recent OS version. Because different distributions rotate at a different pace, the upgrade horizon differs as well. Customers using CentOS should typically upgrade their OS every 3-4 years, while Ubuntu LTS users should do so every 2 years and Alpine, which is typically provisioned in an automated setting (i.e. docker or LXC) should re-provision at least once per year.
