Setting Up Wowza Gradle

Follow these steps to set up your environment for integrating Wowza Streaming Engine with Gradle:

Step 1: Install Prerequisites

• Wowza Streaming Engine: Ensure it is installed and configured.
• Gradle: Download and install it from the official website.
• Java Development Kit (JDK): Install JDK 8 or later for compatibility.

Step 2: Create a Gradle Project

Initialize a new Gradle project using the following command:

bashCopy codegradle init  

Choose these options during setup:

• Project type: application
• Language: Groovy or Kotlin
• Test framework: JUnit

Step 3: Configure build.gradle

Modify the build.gradle file to include dependencies for Wowza.

Example configuration:

groovyCopy codeplugins {  
    id 'java'  
}  

repositories {  
    mavenCentral()  
}  

dependencies {  
    implementation 'com.wowza:wse-api:1.0.0'  
    testImplementation 'org.junit.jupiter:junit-jupiter:5.9.2'  
}  

tasks.test {  
    useJUnitPlatform()  
}  

Step 4: Add Wowza API Libraries

Download Wowza API libraries from the Wowza Developer’s Portal and place them in the libs directory. Update build.gradle to include these libraries:

groovyCopy codedependencies {  
    implementation fileTree(dir: 'libs', include: ['*.jar'])  
}

Building Custom Wowza Modules with Gradle

Wowza modules are Java-based extensions that customize and enhance Wowza’s functionality. Gradle simplifies the development, testing, and deployment of these modules.

Example: A Basic Logging Module

Step 1: Write the Module

Create a Java class for custom logging:

javaCopy codeimport com.wowza.wms.module.ModuleBase;  

public class CustomLoggerModule extends ModuleBase {  
    public void onConnect() {  
        getLogger().info("Client connected.");  
    }  

    public void onDisconnect() {  
        getLogger().info("Client disconnected.");  
    }  
}  

Step 2: Build the Module

Compile the module by running:

bashCopy codegradle build  

Step 3: Deploy the Module

Copy the .jar file from the build/libs directory into the lib folder of your Wowza Streaming Engine installation.

Step 4: Test the Module

Restart the Wowza server and check the logs to verify the functionality of your module.

Advanced Use Cases for Wowza Gradle

1. Automating Deployment

Gradle can automate the deployment of Wowza modules to different environments.

Add a deployment task to build.gradle:

groovyCopy codetask deployModule(type: Copy) {  
    from 'build/libs'  
    into '/path/to/wowza/lib'  
}  

Run the task:

bashCopy codegradle deployModule  

2. Continuous Integration (CI) Setup

Integrate Gradle with CI tools like Jenkins or GitHub Actions to automate builds and tests.

Example GitHub Actions workflow:

yamlCopy codename: Build Wowza Module  

on:  
  push:  
    branches: [main]  

jobs:  
  build:  
    runs-on: ubuntu-latest  
    steps:  
      - uses: actions/checkout@v3  
      - name: Set up JDK  
        uses: actions/setup-java@v3  
        with:  
          java-version: '11'  
      - name: Build Wowza Module  
        run: ./gradlew build  

3. Automated Testing for Wowza Modules

Leverage JUnit or TestNG for automated unit and integration testing.

Example test:

javaCopy codeimport org.junit.jupiter.api.Test;  
import static org.junit.jupiter.api.Assertions.assertEquals;  

public class CustomLoggerModuleTest {  
    @Test  
    void testOnConnect() {  
        CustomLoggerModule module = new CustomLoggerModule();  
        String result = module.onConnect();  
        assertEquals("Client connected.", result);  
    }  
}
