Platform provided media playback controls are enabled by default, and can be disabled by setting the `ShouldShowPlaybackControls` property to `false`.

### Play remote media with custom HTTP headers

A `MediaElement` can send custom HTTP headers when loading remote media. This is useful for authenticated streams that require an `Authorization` header or other custom headers.

```csharp
mediaElement.Source = new UriMediaSource
{
Uri = new Uri("https://example.com/stream.m3u8"),
HttpHeaders = new Dictionary<string, string>
{
["Authorization"] = "Bearer my-token"
}
};
```

Or using the `MediaSource.FromUri` overload:

```csharp
var headers = new Dictionary<string, string>
{
["Authorization"] = "Bearer my-token"
};
mediaElement.Source = MediaSource.FromUri(
new Uri("https://example.com/stream.m3u8"), headers);
```

> [!NOTE]
> HTTP headers are applied to all HTTP requests made for the media source, including manifest and segment downloads for adaptive streams (HLS/DASH). This feature is supported on Android, iOS, macOS, and Windows. Tizen does not support custom HTTP headers.

> [!IMPORTANT]
> On iOS and macOS, custom HTTP headers are set via the `AVURLAssetHTTPHeaderFieldsKey` option, which requires iOS 16.0+ / macOS 13.0+. On earlier versions, custom headers will not be applied.

### Use Rich Media Notifications
A `MediaElement` can show rich media notifications on Android, iOS, Mac Catalyst, and Windows when media is playing in the background. To enable rich media notifications, the following steps are required:
1. Enable background video playback by setting the `enableForegroundService` parameter to `true` when calling the `UseMauiCommunityToolkitMediaElement` method in *MauiProgram.cs*. Refer to the **Initializing the package** section above for more information.

## Understand MediaSource types

A `MediaElement` can play media by setting its `Source` property to a remote or local media file. The `Source` property is of type `MediaSource`, and this class defines three static methods:

The MediaSource static-method list mixes a bare method name (FromUri) with a full signature for the overload (FromUri(Uri, IDictionary<string, string>)). To keep the docs consistent/clear, consider listing both overloads with signatures (e.g., FromUri(Uri) and FromUri(Uri, IDictionary<string,string>)), or list only method names and note that FromUri has an overload accepting headers.

- `FromFile`, returns a `FileMediaSource` instance from a `string` argument.
- `FromUri`, returns a `UriMediaSource` instance from a `Uri` argument.
- `FromUri(Uri, IDictionary<string, string>)`, returns a `UriMediaSource` instance from a `Uri` argument with custom HTTP headers applied to all requests.
- `FromResource`, returns a `ResourceMediaSource` instance from a `string` argument.
- `FromFile(string)`, returns a `FileMediaSource` instance from a `string` argument.
- `FromUri(Uri)`, returns a `UriMediaSource` instance from a `Uri` argument.
- `FromUri(Uri, IDictionary<string, string>)`, returns a `UriMediaSource` instance from a `Uri` argument with custom HTTP headers applied to all requests.
- `FromResource(string)`, returns a `ResourceMediaSource` instance from a `string` argument.

The `MediaSource` class also has these derived classes:

- `FileMediaSource`, which is used to specify a local media file from a `string`. This class has a `Path` property that can be set to a `string`. In addition, this class has implicit operators to convert a `string` to a `FileMediaSource` object, and a `FileMediaSource` object to a `string`.
- `UriMediaSource`, which is used to specify a remote media file from a URI. This class has a `Uri` property that can be set to a `Uri`.
- `UriMediaSource`, which is used to specify a remote media file from a URI. This class has a `Uri` property that can be set to a `Uri`. It also has an `HttpHeaders` property of type `IDictionary<string, string>` that allows setting custom HTTP headers (e.g. `Authorization`) sent with all HTTP requests for this media source, including manifest and segment downloads.
- `ResourceMediaSource`, which is used to specify an embedded file that is provided through the app's resource files. This class has a `Path` property that can be set to a `string`.
