When purchasing a Wowza Streaming Engine license, there is no need to select options, editions or versions, since all the functionality of this unique media server is included in the only possible delivery package - the user obtains everything at once. Licenses differ by the period of technical support and the way of checking the license, but their functionality is the same. Wowza Streaming Engine is not a constructor, but a software product designed to work right out of the box in a large number of usage scenarios, with the possibility of more detailed configuration and refinement through an open API. Also a media server developer, Wowza Media offers a fairly extensive set of additional modules - Wowza functionality extensions created using this API. Some of the modules are available along with the source code, some are only in the form of a ready-made library, but they are all free. They can be downloaded from wowza.com and installed on your server without understanding the intricacies of programming or used as an example to create your own program code. This article was prepared by PWI to familiarize existing Wowza users and those who are just planning to purchase a media server with the modules available for download on wowza.com:
1. Additional security options.
ModuleRefererValidate module for Wowza Streaming Engine
The module is capable to allow viewing the stream from the web page of a specific Internet site only. Validation is performed by verification of the HTTP referer header in the player’s request to view the stream. The module is supplied as a ready-made Wowza library and HTML code examples. To use the module, basic HTML knowledge and minimal Wowza administration experience will suffice. The module provides an initial level of protection against unauthorized viewing. As a serious tool for ensuring the preservation of content, it cannot be considered.
ModuleSecureURLParams module for Wowza Streaming Engine
The module is intended for use with RTMP encoders not supporting the publisher authorization request / response mechanism. The key is passed in the RTMP parameters of the link to publish the stream to the server. To use the module, minimal administration experience is sufficient. The module is part of Wowza and does not require the installation of additional components. Provides a minimum level of protection against unauthorized publication of streams to the server
Authorizing a user to publish a stream can be quite a difficult task to implement on the side of a web server or mobile application, requiring the development or complication of existing program code. At the same time, a similar level of protection can be achieved using an alternative approach that does not require user authorization with the transmission of a password or security settings. You can learn more about this method of protecting a publishing point on this page PWI Secure publisher Addon for Wowza Streaming Engine
OnConnectAuthenticate2 module for Wowza Streaming Engine
This module is similar in functionality to the previous module, but allows you to specify personal authorization parameters for several publishers in a text file
ModuleLimitStreamViewers module for Wowza Streaming Engine
A useful module in a situation where the number of viewers who want to view the stream exceeds the capabilities of the network connection. After setting the limit, all new viewers after reaching the specified value will be denied viewing the stream, without interfering with viewing already connected users. The module is supplied as a binary Wowza library. To use the module, minimal Wowza administration experience will be sufficient.

2. Live stream recording management and VOD Wowza.applications
ModuleMediaListPathSelector module for Wowza Streaming Engine
The module allows you to place video and metadata files (SMIL) in different directories. Files with metadata are needed when VOD content is available in several quality options - multi-bitrate. Each such set of several MP4 files must have one SMIL file. In many cases, storing video and metadata files in the same directory may be undesirable. The module allows you to specify separate paths for each type of file. The module is supplied as Wowza library. To use the module, minimal Wowza administration experience will be sufficient.
ModuleMultiTrackVOD module for Wowza Streaming Engine
The MP4 container allows you to store several videos, audio tracks, as well as data tracks in one physical file. Sometimes video content with translation into several languages is recorded in such files. This module allows specifying query parameters in the viewing URL to play one of the tracks, for example, a specific translation language. The module is supplied as a Wowza .jar library. To use the module, minimal Wowza administration experience will be sufficient.
Using the capabilities of the MP4 container for storing video and sound tracks with translation in one file seems very convenient. But viewing such files in desktop players is sometimes fraught with difficulties, as the choice of a sound track in the player’s interface is not always obvious. If users download files for local viewing, this may be important. In these cases, it’s easier to store several variants of the MP4 file, each with its own soundtrack language. It will require more disk space, but fewer problems with the support of users downloading files. To support both methods of recording and playing MP4 files with several translation languages, a special module has been developed by PWI, which you can find out about here PWI Multilingual SMIL Addon for Wowza Streaming Engine
MediaCacheLocalContent module for Wowza Streaming Engine
The module allows you to configure flexible logic of media server's VOD application with MP4 files located on the local disk (for example, live stream recordings) and files available for download from external sources using the HTTP protocol (cloud storage). When a user requests to view a file, his search will first occur on the local disk, and then in external storage. The module is supplied as a ready .jar library. To install and configure it will require some experience with Wowza and the option to cache Wowza Media Cache in particular.
MediaCachePreload module for Wowza Streaming Engine
This module is used to preload certain files from a remote source into the Wowza Media Cache cache in order to speed up work and reduce network spikes on the first request of VOD content. It can also be used to speed up the work of the VOD application as a whole, since files downloaded to the cache are stored in an optimized format. The module is supplied as a ready library. To install and configure it will require some experience with Wowza and the caching option Wowza Media Cache in particular.

This module allows you to enable the bumper video during a break in the broadcast of a live stream or before the start of a live broadcast. It also supports a list of files , for example commercials instead of a single bumper video. Some Wowza administration experience will be needed to install the module.
For not experienced user, installing and configuring the LoopUntilLive module can be quite a challenge, since it actually requires installing two modules and creating XML files. PWI offers its own solution, with a simplified installation procedure and additional options for automatically switching the input stream to backup streams, taking into account their priority or to bumper file, if there are no backup streams or they are down. You can learn about all the options of the PWI module on this page: PWI stream monitor Addon for Wowza Streaming Engine

After editing the SMIL file, you need to restart the application with the module. The module is intended for advanced users of Wowza.
Despite the fact that the StreamPublisher module has enough functionality to form a static schedule for broadcasting a TV channel, it is difficult to use it in a mode with a frequently changed schedule. As a complete TV automation solution, a specialized model was developed by PWI. It supports playlists with several priorities, a schedule for the days of the week, work with files located in the cloud storage, and much more. The module comes with a web-based management console and allows you to change the schedule without restarting the application and interrupting the stream.
