## How to use

Here is an example of how WebViewer, Webviewer-video and WebViewer-audio could be integrated into your application.

{% tabs %}
{% tab title="JavaScript" %}
{% code lineNumbers="true" %}

```js
import React, { useRef, useEffect } from 'react';
import WebViewer from '@pdftron/webviewer';
import { initializeVideoViewer } from '@pdftron/webviewer-video';
import {
  Waveform,
  initializeAudioViewer
} from '@pdftron/webviewer-audio';

const App = () => {
    const viewer = useRef(null);
    const videoUrl = 'https://pdftron.s3.amazonaws.com/downloads/pl/video/video.mp4';

    useEffect(() => {
      WebViewer(
        {
          path: '/webviewer/lib',
        },
        viewer.current,
      ).then(async instance => {
        await initializeAudioViewer(
          instance,
          { license },
        );

        // Extends WebViewer to allow loading media files (.mp3, .mp4, ogg, webm, etc.)
        const {
            loadVideo,
        } = await initializeVideoViewer(
            instance,
            {
                license: '---- Insert commercial license key here after purchase ----',
                AudioComponent: Waveform,
                cacheAudioWaveform: false,
            }
        );

        // Load a video at a specific url. Can be a local or public link
        // If local it needs to be relative to lib/ui/index.html.
        // Or at the root. (eg '/video.mp4')
        // A unique fileId should be generated for each url for audio caching to work properly
        loadVideo(videoUrl, { fileId: 'testId' });
      });
    }, []);

    return (
        <div className="App">
            <div className="webviewer" ref={viewer} />
        </div>
    );
}

export default App;
```

{% endcode %}
{% endtab %}
{% endtabs %}

## 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://docs.apryse.com/web/video/integrate-audio.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.
