Webcam
------

Renders a `video` element that autoplays the feed from the user's webcam (if allowed). If used with a `ref`, it's possible to take screenshots of the video feed to a data url format.

#### Basic usage

```
<Webcam />
```

#### Advanced usage (screenshots)

In your component, render `Webcam` along with a `ref`:

```
<Webcam ref={(ref) => this.webcam = ref} />
```

and then use that ref to access the `captureScreenshot` method. This methods returns a string with a data-url representation of the current frame of the video feed.

```
this.webcam.captureScreenshot();
```

Alternatively, you can get a binary blob using `captureBlob`. This method takes in a callback with the resulting blob as its single argument.

```
this.webcam.captureBlob((blob) => {
  // ...
});
```

See the `examples` folder for more in-depth examples.
