/**
 * @name Media
 * @premier media
 * @description
 * This plugin provides the ability to record and play back audio files on a device.
 *
 * @usage
 * ```typescript
 * import { Media, MediaObject } from '@ionic-native/media/ngx';
 *
 *
 * constructor(private media: Media) { }
 *
 *
 * ...
 *
 *
 * // Create a Media instance.  Expects path to file or url as argument
 * // We can optionally pass a second argument to track the status of the media
 *
 * const file: MediaObject = this.media.create('file.mp3');
 *
 * // to listen to plugin events:
 *
 * file.onStatusUpdate.subscribe(status => console.log(status)); // fires when file status changes
 *
 * file.onSuccess.subscribe(() => console.log('Action is successful'));
 *
 * file.onError.subscribe(error => console.log('Error!', error));
 *
 * // play the file
 * file.play();
 *
 * // pause the file
 * file.pause();
 *
 * // get current playback position
 * file.getCurrentPosition().then((position) => {
 *   console.log(position);
 * });
 *
 * // get file duration
 * let duration = file.getDuration();
 * console.log(duration);
 *
 * // skip to 10 seconds (expects int value in ms)
 * file.seekTo(10000);
 *
 * // stop playing the file
 * file.stop();
 *
 * // release the native audio resource
 * // Platform Quirks:
 * // iOS simply create a new instance and the old one will be overwritten
 * // Android you must call release() to destroy instances of media when you are done
 * file.release();
 *
 *
 *
 * // Recording to a file
 * const file: MediaObject = this.media.create('path/to/file.mp3');
 *
 * file.startRecord();
 *
 * file.stopRecord();
 *
 *
 * ```
 *
 * Some hints if you are using iOS and recording doesn't work:
 * 1.) Try to use a absolute file path but remove beginning "file://".
 * Then it looks like: `/var/mobile/Containers/Data/Application/AF438B8B-7724-4FBB-8E69-083463224FC4/tmp/my_file.m4a`
 * Example: `this.media.create(this.file.tempDirectory.replace(/^file:\/\//, '') + 'my_file.m4a')`
 * 2.) If that's not working, too, create the file before using.
 * Example:
 * ```typescript
 * import { Media, MediaObject } from '@ionic-native/media/ngx';
 * import { File } from '@ionic-native/file/ngx';
 *
 * ...
 *
 * constructor(private media: Media, private file: File) { }
 *
 * ...
 *
 * this.file.createFile(this.file.tempDirectory, 'my_file.m4a', true).then(() => {
 *   let file = this.media.create(this.file.tempDirectory.replace(/^file:\/\//, '') + 'my_file.m4a');
 *   file.startRecord();
 *   window.setTimeout(() => file.stopRecord(), 10000);
 * });
 * ```
