Installation and update considerations for Wowza Streaming Engine 4.8.16
Wowza Streaming Engine 4.8.5 and later installs a custom packaged version of OpenJDK Java SE JRE 9.0.4 that includes the java.scripting module. This module is required for Wowza Streaming Engine 4.8.16 but is not added by the Wowza Streaming Engine 4.8.16 updater. If you are updating to Wowza Streaming Engine 4.8.16 from a base installation of Wowza Streaming Engine 4.8.0 or earlier, before you update, you need to install a supported version of Java that contains the java.scripting module, such as Java 9-12 or the custom version of OpenJDK Java SE JRE 9.0.4 installed with Wowza Streaming Engine 4.8.16 (available from the Downloads tab of My Account). Then instruct Wowza Streaming Engine to use that version of Java according to the instructions in Manually install and troubleshoot Java on Wowza Streaming Engine.
When using the Wowza Streaming Engine 4.8.16 installer to install a new instance of Wowza Streaming Engine on Windows, you may need to install additional dependencies in order to ingest SRT MediaCaster streams or use the generic SRT stream targets destination to publish an SRT stream. To address this, install the latest version of the Microsoft Visual C++ Redistributable for Visual Studio appropriate to your operating system.
