The new version of Wowza Streaming Engine includes bug fixes, updates to third-party open source components, and some new API features that are useful when integrating Wowza Streaming Engine with custom software. Among the rather extensive list of bug fixes, the most notable are fixes for dead lock in the WMSReentrantReadWriteLock class, performance degradation in the Nvidia transcoder on Ubuntu 24.04, ...
The new version significantly expands the scope of Wowza Streaming Engine due to the ability to install software on new types of devices. Most small single-board computers, such as Raspberry Pi, use the ARM architecture. The WSE installer on ARM did not run in previous versions. Technically, it was possible to run Wowza on a Linux platform with an ARM processor before, by "manually" deploying and configu...
The release of the new version of Wowza Streaming Engine 4.9.4 is marked by a significant improvement in the implementation of the SRT protocol. The new option is called "SRT listener mode", which can be a bit confusing, since SRT "Listener" mode for receiving a stream in Wowza has been around for a long time, there was no "Caller". But in this case, this is Wowza terminology, not the SRT protocol terms....
In this version, the manufacturer has not added any new functionality, but has made a number of changes that, as stated, can significantly improve the performance and reliability of the media server in some usage scenarios. First of all, this applies to transcoding using the Nvidia GPU card. According to the comments from the developers for driver version 550.127.05, the problem with the degradation of ...
In mid-January, Wowza Media released the next version of Wowza Streaming Engine – 4.9.2+6 (build 20250115103439). This release does not contain any security fixes or fundamentally new functionality, but there is a significant improvement in the ability to work with subtitles of the CEA-708 standard. In previous versions of Wowza, text subtitles in the CEA-708 standard received as part of the transport st...
The Wowza 4.9.1+2 release does not introduce any new functionality and is entirely focused on eliminating discovered vulnerabilities and fixing software errors. As many as five vulnerabilities have been discovered by Rapid7 in the REST API and, accordingly, in the Wowza Streaming Engine Manager web management interface. It is not easy to leverage the vulnerabilities for an attack, but the consequences c...
Wowza Media continues its efforts to migrate the Wowza Streaming Engine software to the current Long Term Support (LTS) version of the Java platform. The new version of Wowza 4.9.0 is built using Java 17 libraries (unlike the previous version of Wowza 4.8.28 built on Java 11) and supports both Java 17 and Java 21. Moreover, Java 21 is included in the software installation pack and its presence is require...
Unlike previous releases, Wowza 4.8.28 comes bundled with Java 21 (OpenJDK Java SE JRE 21.0.3) instead of Java 11. The media server components are still built using Java 11, but with the ability to run them, both under Java 11 and all newer versions of Java. Replacing Java with the current LTS (Long-Term Support) release 21 will allow updating its components at least until 2028, which is primarily import...
The main changes in version 4.8.27 relate to an even greater degree of integration of the Wowza Streaming Engine software product and the Wowza Video cloud service. Gradually, it becomes possible to control all the functions of Wowza Video directly through REST API calls provided by the Wowza Streaming Engine installed on-premises. The use of such a hybrid infrastructure from a single vendor carries both...
In this Wowza release, we would like to highlight two points that address issues of security and efficiency of using the media server. The Eclipse Jetty library, one of the third-party components included in the Wowza Streaming Engine, has been updated to address a vulnerability discovered in it. The vendor does not disclose details, but most likely we are talking about CVE-2023-26048 and CVE-2023-2604...
Traditionally for the latest releases of Wowza Streaming Engine, a third of all fixes and new release options relate to transcoding by the AMD Xilinx Alveo U30 graphics card. The process of finalizing this feature continues. We have not yet had the opportunity to evaluate its effectiveness ourselves, but Wowza has published updated performance test data for 3 supported transcoding methods and the results...
As in the previous two updates, half of the changes in the new release relate to the hardware transcoding option with the U30 card. Obviously, Wowza Media developers will need some more time to solve all the problems associated with the support of this card. In addition to fixes for the U30, the new update includes several important improvements that are interesting to the wider number of users. First ...
The new release includes several important options that allow you to use the Wowza Streaming Engine in conjunction with the Wowza Video cloud platform. Closer product integration will allow Wowza Video to offload all the complexity of streaming system scaling to Wowza Video while continuing to use its own Wowza Streaming Engine as a publishing point and media server for local broadcasts. In the new rel...
The main news of the release is the addition of support for the specialized AMD Xilinx Alveo U30 video card for H.264 and H.265 transcoding. It looks like using Wowza with Xilinx will allow you to create extremely productive transcoding systems and will be a good alternative to using Nvidia GPUs. But for now this is just a preview, for the full use of this method Wowza Streaming Engine will be ready in...
This release mainly includes bug fixes, most of which relate to the Wowza Streaming Engine Manager web interface. But there are also some important fixes for errors that lead to problems with the media server performance: Fixed an issue where PushPublish modules were taking too long to return for a failed request. Fixed an issue where network issues caused server crashes. Fixed a bug where RTCP pack...
Wowza Media Systems has acquired Flowplayer, the developer of the HTML5 video player of the same name, one of the most famous and successful software products for viewing videos on a website page. Following its strategy to move from a media server software developer to a global integrated video streaming platform, Wowza has acquired the rights to Flowplayer by taking over a Scandinavian software firm w...
The new release of Wowza Streaming Engine™ 4.8.20 (build 20220919162035) includes bug fixes and additional functionality. The most important fixes are a fix for starting the transcoding process and a fix for transcoding freezing that occurs under certain conditions. A memory leak has also been fixed when converting a WebRTC stream to HLS. Of the new features, it should be noted the use of the Beamr li...
Major changes in the new release. In order to exclude code vulnerable according to CVE-2022-22965 the dependencies of the Spring Cloud libraries were changed when building the Wowza Streaming Engine Manager administration web console. The likelihood of an attack using this vulnerability seems unlikely, but it's still better to update Wowza. Added the ability to digest authentication and store Wowza ...
