# Video stream generator

### :stars: video-stream-generator:

The Job serves the purpose of generating streaming media for the uploaded video contents that have MIME types of MP4 and WebM. This streaming media generation process enables users to efficiently stream and access video content without the need to download the entire video file.

The Job takes the uploaded video files with MP4 and WebM MIME types and processes them to create streaming-friendly versions. These versions are optimized for streaming, allowing users to view the video content in real-time as it is delivered over the internet. By enabling streaming, the Job enhances user experience, reducing buffering time and providing seamless access to video content.

The generated streaming media can be consumed through various streaming services and players, enabling users to access the video content on different devices and platforms without any interruptions. This capability significantly improves the accessibility and usability of the uploaded video contents, making it easier for users to enjoy and interact with the media.

      groupId = "{{ env_name }}-video-stream-generator-group"
    }
```

**Job configuration variables:**
