# Single Media Item Playlists

In some special scenarios, you might only have one media item to play. Using the `SetMediaItem` method can simplify the process of managing your media playback. This method allows you to set a single `MediaItem` directly, without the need to create a playlist manually.

Using `SetMediaItem` is beneficial when you:

* Only need to play one media item.
* Want to quickly replace the current media item without managing a full playlist.
* Simplify your code for single media item scenarios.

### Methods for Setting a Single Media Item

#### Method 1: Replacing the Current Playlist with a New Media Item

This method allows you to replace the entire playlist with a new media item. It is useful when you want to ensure that only one media item is being played.

**Method Signature**

```csharp
public static void SetMediaItem(
    MediaItem mediaItem, 
    int playlistIndex, 
    bool playWhenReady = false, 
    int startMediaItemIndex = 0, 
    float startPosition = 0f);
```

**Parameters:**

* `mediaItem`: The `MediaItem` to set.
* `playlistIndex`: The index of the `Playlist` to set the `MediaItem` to.
* `playWhenReady`: Whether to start playback when the plugin is initialized.
* `startMediaItemIndex`: The index of the `MediaItem` to start playback from.
* `startPosition`: The position to start playback from.

**Example Usage:**

```csharp
MediaItem mediaItem = MediaItem.StreamingAsset("path/to/song.mp3");
MediaPlayer.SetMediaItem(mediaItem, 0, true, 0, 0f);
```

#### Method 2: Setting the Current Media Item Directly

This method allows you to set the current media item directly, using the current playlist index. This is a convenient shortcut if you don't need to specify a different playlist index.

**Method Signature**

```csharp
public static void SetMediaItem(
    MediaItem mediaItem, 
    bool playWhenReady = false, 
    int startMediaItemIndex = 0, 
    float startPosition = 0f);
```

**Parameters:**

* `mediaItem`: The `MediaItem` to set.
* `playWhenReady`: Whether to start playback when the plugin is initialized.
* `startMediaItemIndex`: The index of the `MediaItem` to start playback from.
* `startPosition`: The position to start playback from.

**Example Usage:**

```csharp
MediaItem mediaItem = MediaItem.StreamingAsset("path/to/song.mp3");
MediaPlayer.SetMediaItem(mediaItem, true, 0, 0f);
```

### Full Example

Here is a complete example demonstrating how to create and play a single media item using both methods:

```csharp
// Define your media item
MediaItem mediaItem = MediaItem.StreamingAsset("path/to/song.mp3");

// Setting the media item
MediaPlayer.SetMediaItem(mediaItem); 
```
