Building Wowza Modules with the Wowza Gradle Plugin

Building Wowza modules with the Wowza Gradle Plugin is a straightforward process, thanks to the automation provided by Gradle. In this section, we’ll explore the steps involved in building a Wowza module from start to finish.

Testing and Debugging with the Wowza Gradle Plugin

Testing is a crucial part of the development process, and the Wowza Gradle Plugin makes it easier to write, run, and manage tests for your Wowza modules. Additionally, the plugin provides tools for debugging your modules, helping you identify and fix issues quickly.

Writing Unit Tests

Unit testing is essential for ensuring the reliability of your Wowza modules. With the Wowza Gradle Plugin, you can easily set up and run unit tests using popular testing frameworks like JUnit.

Debugging Your Module

Debugging is a critical step in the development process, especially when working with complex modules that interact with external systems like Wowza Streaming Engine. The Wowza Gradle Plugin integrates seamlessly with IDEs like IntelliJ IDEA and Eclipse, allowing you to set breakpoints, inspect variables, and step through your code during execution.

To debug your module, follow these steps:

Run Wowza in Debug Mode: Start your Wowza Streaming Engine in debug mode by adding the -agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005 JVM option to your Wowza startup script.
Attach the Debugger: In your IDE, configure a remote debugging session that connects to port 5005 on your Wowza server.
Set Breakpoints: Set breakpoints in your module code where you want to pause execution and inspect the state.
Deploy the Module: Use the Wowza Gradle Plugin to deploy your module to the Wowza server.
Trigger the Debugger: Interact with Wowza in a way that triggers your module’s code, and the debugger will pause execution at your breakpoints.

This process allows you to step through your code line by line, inspect variables, and understand the flow of execution, making it easier to identify and fix bugs.

Deploying Wowza Modules Using the Wowza Gradle Plugin

Once your Wowza module is built and tested, the next step is deployment. The Wowza Gradle Plugin simplifies this process by automating the deployment of your modules to the Wowza Streaming Engine, ensuring that your modules are correctly installed and ready to use.

Deploying to a Local Wowza Server

To deploy your Wowza module to a local Wowza Streaming Engine instance, you can use the deploy task provided by the Wowza Gradle Plugin. Here’s how to do it:

Configure the Deployment Directory: Ensure that the deployDir property in your build.gradle file is set to the correct Wowza module directory.groovyCopy codewowza { deployDir = '/usr/local/WowzaStreamingEngine/lib' }
Run the Deployment Task: Execute the following Gradle command to deploy your module:bashCopy codegradle deploy

This command copies the compiled JAR file of your module to the Wowza Streaming Engine’s lib directory, making it available for use.

Verifying the Deployment

After deploying your module, it’s important to verify that it has been installed correctly and is functioning as expected. You can do this by:

Checking the Wowza Logs: Review the Wowza Streaming Engine logs for any errors or warnings related to your module.
Testing the Module: Interact with Wowza in a way that triggers your module’s functionality, and verify that it behaves as expected.
Reviewing the Configuration: Ensure that your module is listed in the Wowza Streaming Engine Manager and that it’s correctly configured.
