Wowza Streaming Engine™ 4.8.26+3 build 20231207183517 released December 11, 2023.
New features and functionality in Wowza Streaming Engine 4.8.26
Added CMAF improvements
To lead innovation and move the industry towards better playback and packaging standards, we've improved our Common Media Application Format (CMAF) workflows. SRT and CMAF formats offer the best end-to-end HEVC-capable playback over HLS, with significant bitrate reductions that can eliminate cost and bandwidth concerns. Version 4.8.26 of Wowza Streaming Engine delivers the following CMAF enhancements:
Added the ability to configure live applications in Wowza Streaming Engine Manager to deliver CMAF streams. This UI-based approach provides a more convenient alternative to the previous XML method used for the same goal. Learn how to create CMAF streams using Wowza Streaming Engine Manager.
Added a push publish workflow to distribute CMAF HLS stream targets to Wowza Video and cloud providers like Oracle and AWS. To learn more about this new feature, see Use CMAF to distribute live streams from Wowza Streaming Engine.
Updated castLabs DRMtoday module
We've updated the setup and documentation for the castLabs DRMtoday module to reflect its support for key rotation in version 3.1.0. Key rotation enhances security and minimizes vulnerabilities by allowing you to rotate keys that encrypt content over time. For more details about setting up secure video delivery in Wowza Streaming Engine, see the updated Set up castLabs DRMtoday article.
Improved AMD Xilinx accelerated transcoding
In Wowza Streaming Engine 4.8.25, we added support to transcode WebRTC inputs with the AMD Xilinx Alveo U30 card in preview mode. While the preview version has some limitations, we've improved the stability for WebRTC inputs when using the U30 cards in Wowza Streaming Engine 4.8.26. These enhancements limit the number of crashes when resolution changes occur with input sources. For more, see WebRTC input-specific limitations in Wowza Streaming Engine.
