# Methods
This page shows the list of available methods
### `dismissFullscreenPlayer`
`dismissFullscreenPlayer(): Promise`
Take the player out of fullscreen mode.
> [!WARNING]
> deprecated, use setFullScreen method instead
### `pause`
`pause(): Promise`
Pause the video.
### `presentFullscreenPlayer`
`presentFullscreenPlayer(): Promise`
Put the player in fullscreen mode.
On iOS, this displays the video in a fullscreen view controller with controls.
On Android, this puts the navigation controls in fullscreen mode. It is not a complete fullscreen implementation, so you will still need to apply a style that makes the width and height match your screen dimensions to get a fullscreen video.
> [!WARNING]
> deprecated, use setFullScreen method instead
### `resume`
`resume(): Promise`
Resume the video.
### `restoreUserInterfaceForPictureInPictureStopCompleted`
`restoreUserInterfaceForPictureInPictureStopCompleted(restored)`
This function corresponds to the completion handler in Apple's [restoreUserInterfaceForPictureInPictureStop](https://developer.apple.com/documentation/avkit/avpictureinpicturecontrollerdelegate/1614703-pictureinpicturecontroller?language=objc). IMPORTANT: This function must be called after `onRestoreUserInterfaceForPictureInPictureStop` is called.
### `save`
`save(): Promise<{ uri: string }>`
Save video to your Photos with current filter prop. Returns promise.
Notes:
- Currently only supports highest quality export
- Currently only supports MP4 export
- Currently only supports exporting to user's cache directory with a generated UUID filename.
- User will need to remove the saved video through their Photos app
- Works with cached videos as well. (Checkout video-caching example)
- If the video is has not began buffering (e.g. there is no internet connection) then the save function will throw an error.
- If the video is buffering then the save function promise will return after the video has finished buffering and processing.
Future:
- Will support multiple qualities through options
- Will support more formats in the future through options
- Will support custom directory and file name through options
### `seek`
`seek(seconds)`
Seek to the specified position represented by seconds. seconds is a float value.
`seek()` can only be called after the `onLoad` event has fired. Once completed, the [onSeek](./events#onseek) event will be called.
#### Exact seek
By default iOS seeks within 100 milliseconds of the target position. If you need more accuracy, you can use the seek with tolerance method:
`seek(seconds, tolerance)`
tolerance is the max distance in milliseconds from the seconds position that's allowed. Using a more exact tolerance can cause seeks to take longer. If you want to seek exactly, set tolerance to 0.
### `setVolume`
`setVolume(value): Promise`
This function will change the volume exactly like [volume](./props#volume) property. default value and range are the same then.
### `getCurrentPosition`
`getCurrentPosition(): Promise`
This function retrieves and returns the precise current position of the video playback, measured in seconds.
This function will throw an error if player is not initialized.
### `setSource`
`setSource(source: ReactVideoSource): Promise`
This function will change the source exactly like [source](./props#source) property.
Changing source with this function will overide source provided as props.
### `setFullScreen`
`setFullScreen(fullscreen): Promise`
If you set it to `true`, the player enters fullscreen mode. If you set it to `false`, the player exits fullscreen mode.
On iOS, this displays the video in a fullscreen view controller with controls.
On Android, this puts the navigation controls in fullscreen mode. It is not a complete fullscreen implementation, so you will still need to apply a style that makes the width and height match your screen dimensions to get a fullscreen video.
### Example Usage
```tsx
const videoRef = useRef(null);
const someCoolFunctions = async () => {
if (!videoRef.current) {
return;
}
// present or dismiss fullscreen player
videoRef.current.presentFullscreenPlayer();
videoRef.current.dismissFullscreenPlayer();
// pause or resume the video
videoRef.current.pause();
videoRef.current.resume();
// save video to your Photos with current filter prop
const response = await videoRef.current.save();
const path = response.uri;
// seek to the specified position represented by seconds
videoRef.current.seek(200);
// or on iOS you can seek with tolerance
videoRef.current.seek(200, 10);
};
return (
);
```
## Static methods
### `getWidevineLevel`
Indicates whether the widevine level supported by device.
Possible values are:
- 0 - unable to determine widevine support (typically not supported)
- 1, 2, 3 - Widevine level supported
### `isCodecSupported`
Indicates whether the provided codec is supported level supported by device.
parameters:
- `mimetype`: mime type of codec to query
- `width`, `height`: resolution to query
Possible results:
- `hardware` - codec is supported by hardware
- `software` - codec is supported by software only
- `unsupported` - codec is not supported
### `isHEVCSupported`
Helper which Indicates whether the provided HEVC/1920\*1080 is supported level supported by device. It uses isCodecSupported internally.
### Example Usage
```tsx
import { VideoDecoderProperties } from 'react-native-video';
VideoDecoderProperties.getWidevineLevel().then((level) => {
...
});
VideoDecoderProperties.isCodecSupported('video/hevc', 1920, 1080).then((support) => {
...
});
VideoDecoderProperties.isHEVCSupported().then((support) => {
...
});
```
