[Topic] WSE 4.8.26 What's New

Wowza Streaming Engine is a robust, customizable, and scalable media server software that powers reliable streaming of high-quality video and audio to any device, anywhere. Wowza Streaming Engine 4.8.26 contains enhancements and fixes that improve the functionality of the media server software.

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:

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.
