Setup your Podfile like it is described in the [react-native documentation](https://facebook.github.io/react-native/docs/integration-with-existing-apps#configuring-cocoapods-dependencies).
Depending on your requirements you have to choose between the two possible subpodspecs:
video only:
```diff
pod 'Folly', :podspec => '../node_modules/react-native/third-party-podspecs/Folly.podspec'
* [Enable Background Audio](https://developer.apple.com/library/archive/documentation/Audio/Conceptual/AudioSessionProgrammingGuide/AudioSessionBasics/AudioSessionBasics.html#//apple_ref/doc/uid/TP40007875-CH3-SW3) in your Xcode project
Determines how to resize the poster image when the frame doesn't match the raw video dimensions.
* **"contain" (default)** - Scale the image uniformly (maintain the image's aspect ratio) so that both dimensions (width and height) of the image will be equal to or less than the corresponding dimension of the view (minus padding).
* **"center"** - Center the image in the view along both dimensions. If the image is larger than the view, scale it down uniformly so that it is contained in the view.
* **"cover"** - Scale the image uniformly (maintain the image's aspect ratio) so that both dimensions (width and height) of the image will be equal to or larger than the corresponding dimension of the view (minus padding).
* **"contain"** - Scale the video uniformly (maintain the video's aspect ratio) so that both dimensions (width and height) of the video will be equal to or less than the corresponding dimension of the view (minus padding).
* **"cover"** - Scale the video uniformly (maintain the video's aspect ratio) so that both dimensions (width and height) of the image will be equal to or larger than the corresponding dimension of the view (minus padding).
"system" (default) | N/A | Play the audio track that matches the system language. If none match, play the first track.
"disabled" | N/A | Turn off audio
"title" | string | Play the audio track with the title specified as the Value, e.g. "French"
"language" | string | Play the audio track with the language specified as the Value, e.g. "fr"
"index" | number | Play the audio track with the index specified as the value, e.g. 0
If a track matching the specified Type (and Value if appropriate) is unavailable, the first audio track will be played. If multiple tracks match the criteria, the first match will be used.
Both iOS & Android (only 4.4 and higher) offer Settings to enable Captions for hearing impaired people. If "system" is selected and the Captions Setting is enabled, iOS/Android will look for a caption that matches that customer's language and display it.
If a track matching the specified Type (and Value if appropriate) is unavailable, no text track will be displayed. If multiple tracks match the criteria, the first match will be used.
type | Mime type of the track<br>* TextTrackType.SRT - SubRip (.srt)<br> * TextTrackType.TTML - TTML (.ttml)<br> * TextTrackType.VTT - WebVTT (.vtt)<br>iOS only supports VTT, Android ExoPlayer supports all 3
On iOS, sidecar text tracks are only supported for individual files, not HLS playlists. For HLS, you should include the text tracks as part of the playlist.
Output to a TextureView instead of the default SurfaceView. In general, you will want to use SurfaceView because it is more efficient and provides better performance. However, SurfaceViews has two limitations:
Callback function that is called when the audio is about to become 'noisy' due to a change in audio outputs. Typically this is called when audio output is being switched from an external source like headphones back to the internal speaker. It's a good idea to pause the media when this happens so the speaker doesn't start blasting sound.
currentPosition | number | Time in seconds where the media will start
duration | number | Length of the media in seconds
naturalSize | object | Properties:<br>* width - Width in pixels that the video was encoded at<br> * height - Height in pixels that the video was encoded at<br> * orientation - "portrait" or "landscape"
audioTracks | array | An array of audio track info objects with the following properties:<br>* index - Index number<br> * title - Description of the track<br>* language - 2 letter [ISO 639-1](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) or 3 letter [ISO639-2](https://en.wikipedia.org/wiki/List_of_ISO_639-2_codes) language code<br> * type - Mime type of track
textTracks | array | An array of text track info objects with the following properties:<br>* index - Index number<br> * title - Description of the track<br>* language - 2 letter [ISO 639-1](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes) or 3 letter [ISO 639-2](https://en.wikipedia.org/wiki/List_of_ISO_639-2_codes) language code<br> * type - Mime type of track
On iOS, this displays the video in a fullscreen view controller with controls.
On Android ExoPlayer & MediaPlayer, 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.
Seek to the specified position represented by seconds. seconds is a float value.
`seek()` can only be called after the `onLoad` event has fired.
Example:
```
this.player.seek(200); // Seek to 3 minutes, 20 seconds
```
Platforms: all
##### 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.
Example:
```
this.player.seek(120, 50); // Seek to 2 minutes with +/- 50 milliseconds accuracy
To see the full list of available props, you can check the [propTypes](https://github.com/react-native-community/react-native-video/blob/master/Video.js#L246) of the Video.js component.
- By default, iOS 9+ will only load encrypted HTTPS urls. If you need to load content from a webserver that only supports HTTP, you will need to modify your Info.plist file and add the following entry:
The asset system [introduced in RN `0.14`](http://www.reactnative.com/react-native-v0-14-0-released/) allows loading image resources shared across iOS and Android without touching native code. As of RN `0.31` [the same is true](https://github.com/facebook/react-native/commit/91ff6868a554c4930fd5fda6ba8044dbd56c8374) of mp4 video assets for Android. As of [RN `0.33`](https://github.com/facebook/react-native/releases/tag/v0.33.0) iOS is also supported. Requires `react-native-video@0.9.0`.
To enable audio to play in background on iOS the audio session needs to be set to `AVAudioSessionCategoryPlayback`. See [Apple documentation][3] for additional details. (NOTE: there is now a ticket to [expose this as a prop]( https://github.com/react-native-community/react-native-video/issues/310) )
- See an [Example integration][1] in `react-native-login`*note that this example uses an older version of this library, before we used `export default` -- if you use `require` you will need to do `require('react-native-video').default` as per instructions above.*
Previously, on Android ExoPlayer if the paused prop was not set, the media would not automatically start playing. The only way it would work was if you set `paused={false}`. This has been changed to automatically play if paused is not set so that the behavior is consistent across platforms.
#### All platforms now keep their paused state when returning from the background
Previously, on Android MediaPlayer if you setup an AppState event when the app went into the background and set a paused prop so that when you returned to the app the video would be paused it would be ignored.
Note, Windows does not have a concept of an app going into the background, so this doesn't apply there.
#### Use Android SDK 27 by default
Version 3.0 updates the Android build tools and SDK to version 27. React Native is in the process of [switchting over](https://github.com/facebook/react-native/issues/18095#issuecomment-395596130) to SDK 27 in preparation for Google's requirement that new Android apps [use SDK 26](https://android-developers.googleblog.com/2017/12/improving-app-security-and-performance.html) by August 2018.
You will either need to install the version 27 SDK and version 27.0.3 buildtools or modify your build.gradle file to configure react-native-video to use the same build settings as the rest of your app as described below.
You will need to create a `project.ext` section in the top-level build.gradle file (not app/build.gradle). Fill in the values from the example below using the values found in your app/build.gradle file.
```
// Top-level build file where you can add configuration options common to all sub-projects/modules.
