Although programmatic and command-line configuration and management of Wowza Streaming Engine is still available, the browser-based manager offers key benefits that enable publishers with a diverse range of technical abilities to have greater control and confidence when streaming video.

Why should I use Wowza Streaming Engine 4.8.13?

Wowza Streaming Engine 4.8.13 contains several fixes and enhancements that help to improve the functionality of the media server software.

What administration consoles can I use?

The server can be administered with any Java Management Extension–compatible administration console, such as JConsole (available with the Java JDK) or the open source MC4J JMX browser, free of charge. Wowza Streaming Engine can also be administered from HP OpenView, Tivoli, IBM Websphere, BEA Weblogic, SNMP and many other management platforms.


What operating systems does Wowza Streaming Engine run on?

Wowza Streaming Engine runs on any platform that supports Java 9 (OpenJDK Java SE JRE 9.0.4) or later. Installer packages are available for Windows, Linux, and OS X. For best performance, we recommend using a 64-bit OS.

What are the hardware requirements?

At a minimum, we recommend a quad-core system with at least 8 GB of RAM. To get the most throughput out of Wowza Streaming Engine software we suggest you use RAID 0 or RAID 10 configurations with two or more disks in the array for on-demand streaming. Depending upon your application and load, you may need more or less horsepower.

What operating systems does Wowza Transcoder run on?

Operation of Wowza Transcoder requires 64-bit Windows or Linux. This includes the use of Intel Media SDK, or NVIDIA CUDA and NVIDIA NVENC SDK acceleration technologies.


Is there a tool for server-side programming?

You can utilize industry-standard development tools to accomplish the server-side programming tasks. Wowza offers the free Eclipse-based integrated development environment (IDE), which greatly simplifies and streamlines the tasks of extending, configuring, and managing the Wowza Media Systems products. The download information for this free development tool can be found on our Wowza IDE page.

Does Wowza Streaming Engine provide back-end system integration?

Our extensible Java API provides a wide variety of system-integration options. Integration options include web services, JNI (Java Native Interface), direct Java integration, XML, remote procedure calls, and others.

Can I use server-side programming with Wowza Streaming Engine?

Yes. Server-side programming is in Java. Wowza Streaming Engine offers an extensive API to give you maximum flexibility. For more information please refer to the Wowza Streaming Engine API Overview page or the Wowza Streaming Engine Rest API page.

What resources are available for developers?

Do I need to use Wowza Transcoder to repackage a stream from one transport protocol to another?

No. The core Wowza Streaming Engine software offers native capability for repackaging (i.e., transmultiplexing) H.264 content from one incoming transport protocol type (for example, RTMP) to a different outgoing transport protocol (for example, HLS). You need to use the transcoding feature only if you need to convert a non-H.264 incoming stream to H.264 streams, and/or change the bitrate or encoding profile of the incoming stream. Learn more about Wowza Transcoder.

How can I get support?

Wowza offers multiple technical-support resources for our user community. Please visit the support area of the website for complete details about support resources, including email, forums, guides, tutorials, and code samples. Also see more information about the Wowza premium support offering.

Why do I need a maintenance and support contract?

Maintenance and support contracts are required in order to receive software upgrades and updates, R&D licenses, and technical support. Perpetual edition customers must purchase contract renewals prior to the contract expiration date. Subscription customers do not need to purchase contract renewals because maintenance and support is built into the subscription. Learn more about maintenance and support.

Performance and Scalability

Can I load-balance across multiple Wowza Streaming Engine instances?

Yes, there is support for load-balancing between multiple Wowza Streaming Engine instances. Wowza Streaming Engine also includes a very scalable HTTP-based caching mechanism for multiple-server delivery for on-demand streaming. For more information, please visit the Load Balancing Overview page.

Can I load-balance across multiple Wowza Streaming Engine instances?

Yes, there is support for load-balancing between multiple Wowza Streaming Engine instances. Wowza Streaming Engine also includes a very scalable HTTP-based caching mechanism for multiple-server delivery for on-demand streaming. For more information, please visit the Load Balancing Overview page.

Do you offer a load-testing tool?

Yes, the Load Test Tool can simulate connections for load testing on Wowza Streaming Engine 4.5 and later. This tool enables you to configure, control, and monitor load tests through a web-based interface.

How can I maximize the server on-demand performance?

A lot of Wowza Streaming Engine software performance is driven by the I/O performance of the underlying server. Wowza Streaming Engine software can go only as fast as the server can deliver content bits from the disk. To get the most throughput out of Wowza Streaming Engine, we suggest you use RAID 0 or RAID 10 configurations with as many disks as possible in the RAID array. In addition, utilization of Media Cache improves performance by caching on-demand content.

Can Wowza Streaming Engine deliver up to 10 Gbps of streaming from a single server?

Our customers have been able to get up to 10 Gbps of streaming performance for both live and on-demand media on multithreaded, multi-CPU machines that were finely tuned at the kernel level. On standard servers with dual quad-core processors and multiple NICs, up to 5 Gbps of streaming performance can be achieved if the server is properly tuned. Tuning guidance is available in our Performance Tuning Guide.

Is Wowza Streaming Engine scalable?

Yes. Wowza Streaming Engine is a highly scalable, tightly coded, multithreaded Java server. The software effectively utilizes CPU (unlimited cores/threads per instance) and memory resources to let you get more connection capacity out of any given hardware. The connection capacity in most cases is limited by the disk I/O or network interface performance.


Are AddOns available for Wowza Streaming Engine?

Free AddOns, such as StreamLock, Load Balancing, and GeoIP Locking, are available with Wowza Streaming Engine software. Learn more about Wowza Streaming Engine AddOns.
