### How to use it for MP4 files
Once installed, you can embed MP4 videos in your wiki pages using the following syntax:

```wikitext
{{#ev:local|filename.mp4}}
```

**Key Features:**
*   **Local Files:** Use the `local` parameter to point to files uploaded to your wiki.
*   **External Platforms:** You can also use it for YouTube, Vimeo, and other platforms by using the service name instead of `local` (e.g., `{{#ev:youtube|VIDEO_ID}}`).
*   **Customization:** You can add parameters for width, alignment, and description:
    ```wikitext
    {{#ev:local|myvideo.mp4|400|left|My Video Description}}
    ```

### Troubleshooting Tips
*   **Permissions:** Ensure the user running your web server (e.g., `www-data` or `apache`) has read/write permissions for the `extensions/EmbedVideo` folder.
*   **Cache:** If the video does not appear immediately, try clearing your browser cache or the MediaWiki cache by running `php maintenance/rebuildLocalisationCache.php` from your command line.
*   **Dependencies:** Ensure your server has the necessary PHP extensions enabled to handle video processing if you intend to use advanced features.
