Streams in the following container formats can be played directly by ExoPlayer. The contained audio and video sample formats must also be supported (see the[Sample formats](https://developer.android.com/media/media3/exoplayer/supported-formats#sample-formats)section for details). For image container and format support, see[Images](https://developer.android.com/media/media3/exoplayer/images).

\* Seeking is unsupported because the container does not provide metadata (for example, a sample index) to allow a media player to perform a seek in an efficient way. If seeking is required, we suggest using a more appropriate container format.

\*\* These extractors have`FLAG_ENABLE_CONSTANT_BITRATE_SEEKING`flags for enabling approximate seeking using a constant bitrate assumption. This functionality is not enabled by default. The simplest way to enable this functionality for all extractors that support it is to use`DefaultExtractorsFactory.setConstantBitrateSeekingEnabled`, as described[here](https://developer.android.com/media/media3/exoplayer/customization#enabling-constant-bitrate-seeking).

\*\*\* The[FLAC library](https://github.com/androidx/media/tree/release/libraries/decoder_flac)extractor outputs raw audio, which can be handled by the framework on all API levels. The[ExoPlayer library](https://github.com/androidx/media/tree/release/libraries/exoplayer)FLAC extractor outputs FLAC audio frames and so relies on having a FLAC decoder (for example, a`MediaCodec`decoder that handles FLAC (required from API level 27), or the[FFmpeg library](https://github.com/androidx/media/tree/release/libraries/decoder_ffmpeg)with FLAC enabled). The`DefaultExtractorsFactory`uses the extension extractor if the application was built with the[FLAC library](https://github.com/androidx/media/tree/release/libraries/decoder_flac). Otherwise, it uses the[ExoPlayer library](https://github.com/androidx/media/tree/release/libraries/exoplayer)extractor.

## Using MediaItem

To play a progressive stream, create a`MediaItem`with the media URI and pass it to the player.  

### Kotlin

```kotlin
// Create a player instance.
val player = ExoPlayer.Builder(context).build()
// Set the media item to be played.
player.setMediaItem(MediaItem.fromUri(progressiveUri))
// Prepare the player.
player.prepare()
```

### Java

```java
// Create a player instance.
ExoPlayer player = new ExoPlayer.Builder(context).build();
// Set the media item to be played.
player.setMediaItem(MediaItem.fromUri(progressiveUri));
// Prepare the player.
player.prepare();
```

<br />

## Using ProgressiveMediaSource

For more customization options, you can create a`ProgressiveMediaSource`and pass it directly to the player instead of a`MediaItem`.  

### Kotlin

```kotlin
// Create a data source factory.
val dataSourceFactory: DataSource.Factory = DefaultHttpDataSource.Factory()
// Create a progressive media source pointing to a stream uri.
val mediaSource: MediaSource =
ProgressiveMediaSource.Factory(dataSourceFactory)
    .createMediaSource(MediaItem.fromUri(progressiveUri))
// Create a player instance.
val player = ExoPlayer.Builder(context).build()
// Set the media source to be played.
player.setMediaSource(mediaSource)
// Prepare the player.
player.prepare()
```

### Java

```java
// Create a data source factory.
DataSource.Factory dataSourceFactory = new DefaultHttpDataSource.Factory();
// Create a progressive media source pointing to a stream uri.
MediaSource mediaSource =
    new ProgressiveMediaSource.Factory(dataSourceFactory)
        .createMediaSource(MediaItem.fromUri(progressiveUri));
// Create a player instance.
ExoPlayer player = new ExoPlayer.Builder(context).build();
// Set the media source to be played.
player.setMediaSource(mediaSource);
// Prepare the player.
player.prepare();
```

## Customizing playback

ExoPlayer provides multiple ways for you to tailor playback experience to your app's needs. See the[Customization page](https://developer.android.com/guide/topics/media/exoplayer/customization)for examples.
