- What OS platforms does Wowza Streaming Engine run on?
Wowza Streaming Engine, as well as the nDVR and DRM Premium AddOns, run on any platform that supports the Java Runtime Environment (JRE) 6 (a.k.a. 1.6) or later. Installer packages are available for Windows, Linux, and OS X. For best performance, we recommend using a 64-bit OS. You will also need to have Java Runtime Environment (JRE) or Java Development Kit (JDK) installed.
- What are the hardware requirements?
As 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 at least 2 or more disks in the array for on-demand. Depending upon your application and load, you may need more or less horsepower.
- Where can I download Java Runtime Environment (JRE)?
Java downloads are available at www.oracle.com/technetwork/java/javase/downloads/index.html
- What OS platforms does Wowza Transcoder AddOn run on?
Operation of Wowza Transcoder AddOn requires 64-bit Windows or Linux. This includes the use of Intel Media SDK, or NVIDIA CUDA and NVIDIA NVENC SDK acceleration technologies as well.
- Is there a tool for server-side programming?
You can utilize industry-standard development tools to accomplish the server-side programming tasks. Wowza offers 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 backend 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 document found on the Documentation page.
- What resources are available for developers?
Wowza is committed to supporting our developer community and offers a variety of tools and resources, including a developer license for use in building products and applications on the Wowza platform. Learn more about resources for Wowza developers.
Operations & Support
- What live encoders can I use with Wowza Streaming Engine?
Wowza Streaming Engine supports a wide range of H.264 encoders that use RTMP, RTSP/RTP, or MPEG-TS protocols. Encoders can be either unicast or multicast. For more information on compatible encoders, visit the Live Streaming and Encoders section on the Wowza forums.
- Does Wowza Streaming Engine support H.264/AAC streaming?
Wowza Streaming Engine supports a wide variety of protocols and codecs. See the complete specifications.
- Do you support re-streaming of SHOUTcast or Icecast streams?
Yes. Wowza Streaming Engine supports re-streaming of MP3 and AAC SHOUTcast/Icecast streams to the all supported player technologies. (At this time the Silverlight Smooth Streaming player is not able to support audio-only streams. One solution is to add a very low bit rate video stream.)
- 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 software maintenance and support policy.
Performance & 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.
- How can I scale live streaming beyond a single server?
Wowza Streaming Engine instances can easily be configured in an origin and edge architecture to deliver live media content across multiple servers. This functionality is built-in and will require additional licenses for each Wowza instance.
- Do you offer a load-testing tool?
We offer an RTMP Load Test tool that simulates load to benchmark performance of Wowza Streaming Engine in your environment. For more information, see our Flash RTMP Load Test Tool page.
- 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 only go 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 MediaCache improves performance by caching on-demand content.
- Can Wowza Streaming Engine deliver up to 10Gbps of streaming from a single server?
Some of our customers have been able to get up to 10Gbps of streaming performance for both live and on-demand on multi-threaded, multi-CPU machines that were finely tuned at the kernel level. On standard servers with dual quad-core processors and multiple NICs, up to 5Gbps 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 multi-threaded 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.
