# 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.

### Code:

{% embed url="<https://github.com/Sunbird-Knowlg/knowledge-platform-jobs/tree/release-5.5.0/video-stream-generator>" %}

### Configuration:

During the deployment process, the configuration for all knowledge-platform-jobs is sourced from the sunbird-learning-platform repository. On the other hand, for local setups, the configuration is taken from the respective job folders within the knowledge-platform-jobs repository.

**Kafka Topic:**

```
kafka {
      input.topic = "{{ env_name }}.content.postpublish.request"
      groupId = "{{ env_name }}-video-stream-generator-group"
    }
```

**Job configuration variables:**

| Variable                 | Purpose                                                                                                                              |
| ------------------------ | ------------------------------------------------------------------------------------------------------------------------------------ |
| service.content.basePath | Used to configure Content Service API base path for accessing System Update API (/content/v4/system/update/ - not exposed publicly). |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://knowlg.sunbird.org/learn/product-and-developer-guide/content-service/content-apis/jobs/video-stream-generator.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
