+# video_player_tizen
+
+The Tizen implementation of [`video_player`](https://github.com/flutter/plugins/tree/master/packages/video_player).
+
+## Required privileges
+
+To use this plugin in a Tizen application, the mediastorage, externalstorage and internet privileges are required. Add below lines under the `<manifest>` section in your `tizen-manifest.xml` file.
+
+```xml
+<privileges>
+  <privilege>http://tizen.org/privilege/mediastorage</privilege>
+  <privilege>http://tizen.org/privilege/externalstorage</privilege>
+  <privilege>http://tizen.org/privilege/internet</privilege>
+</privileges>
+```
+
+- The mediastorage privilege (`http://tizen.org/privilege/mediastorage`) must be added to play video files located in the internal storage.
+- The externalstorage privilege (`http://tizen.org/privilege/externalstorage`) must be added to play video files located in the external storage.
+- The internet privilege (`http://tizen.org/privilege/internet`) must be added to play any URLs from network.
+
+For details, see [Security and API Privileges](https://docs.tizen.org/application/dotnet/tutorials/sec-privileges).
+
+## Usage
+
+This package is not an _endorsed_ implementation of `video_player`. Therefore, you have to include `video_player_tizen` alongside `video_player` as dependencies in your `pubspec.yaml` file.
+
+```yaml
+dependencies:
+  video_player: ^2.1.0
+  video_player_tizen: ^1.0.0
+```
+
+Then you can import `video_player` in your Dart code:
+
+```dart
+import 'package:video_player/video_player.dart';
+```
+
+For how to use the plugin, see https://github.com/flutter/plugins/tree/master/packages/video_player/video_player#usage.
+
+## Limitations
+
+The 'httpheaders' option for 'VideoPlayerController.network' and 'mixWithOthers' option of 'VideoPlayerOptions' will be silently ignored in Tizen platform.
+
+This plugin has some limitations on TV:
+
+- Don't change playback speed at last 3 senconds when playing video, otherwise it will be failed.
+- If playing a video in a loop and change the playback speed(not 1.0) successfully, the playback speed will be recovered to 1.0 when play video again.
+- Don't use seekTo if playback speed isn't 1.0, seekTo doesn't work after change playback speed.
+- The video has some key frames, seekTo will set position to the key frame. For example, the video has key frame on 0 second and 3 second, actually the position is at 3 second when seek the position to 2 second.
