[Topic] WSE 4.8.25 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 4.8.25 contains enhancements and fixes that improve the functionality of the media server software.

Added SRT improvements

We made several SRT improvements to keep our implementation up to date with the latest from the SRT Alliance. As part of these changes, we added support for multiple audio tracks when streaming using the SRT protocol. For more information, see:

We also updated several Java API methods to access information about SRT sessions and fixed several SRT-related bugs.

Improved AMD Xilinx accelerated transcoding

The Wowza Streaming Engine 4.8.25 release contains additions and improvements to the AMD Xilinx Alveo U30 transcoding workflow. These changes include the following:

  • Changed the default behavior for the AMD Xilinx U30 card to prevent it from overflowing to CPU (MainConcept) transcoding when it's transcoding too many streams. Wowza Streaming Engine versions 4.8.21 to 4.8.24 automatically overflow to use MainConcept transcoding when the U30 card has reached its capacity.
  • Added a new parameter that allows a switch to CPU (MainConcept) transcoding when the AMD Xilinx 30 card is over capacity. For more, see Enable fallback to CPU transcoding.
  • Added support to transcode WebRTC inputs using the AMD Xilinx Alveo U30 card. This feature is only available in preview mode, and you may experience some limitations. For related configuration options, see Allocate resources to use WebRTC with U30.
  • Added support for properties related to the lookahead module to allow better video quality tuning when using the AMD Xilinx Alveo U30 card.
  • Added support for streaming 10-bit color-depth videos that are transcoded with an AMD Xilinx Alveo U30 card.
