The uni video component is straightforward to use. You can embed a video by simply adding the <video> tag to your HTML and setting the appropriate attributes. For instance, you can specify the video source using the src attribute and control the video controls using the controls attribute.
| Attribute | Description |

| src | URL of the video source |
| controls | Enables or disables video controls |
| autoplay | Automatically plays the video when the page loads |
| loop | Repeats the video indefinitely |
Controlling the Video
Uni-app provides a variety of methods to control the video component. You can use these methods to play, pause, seek, and more. Here’s a brief overview of some of the most commonly used methods:
| Method | Description |
|---|---|
| uni.createVideoContext | Creates a video context object that allows you to control the video |
| videoContext.play | Plays the video |
| videoContext.pause | Pauses the video |
| videoContext.seek | Seeks to a specific time in the video |
Handling Events
