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 section for details).

Container format Supported Comments
WebM YES  
Matroska YES  
MP3 YES Some streams only seekable using constant bitrate seeking**
Ogg YES Containing Vorbis, Opus and FLAC
FLV YES Not seekable*
ADTS (AAC) YES Only seekable using constant bitrate seeking**
FLAC YES Using the FLAC extension or the FLAC extractor in the core library***
AMR YES Only seekable using constant bitrate seeking**
JPEG motion photo YES Only the MP4 content is extracted

* Seeking is unsupported because the container does not provide metadata (e.g., 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.

*** The FLAC extension extractor outputs raw audio, which can be handled by the framework on all API levels. The core library FLAC extractor outputs FLAC audio frames and so relies on having a FLAC decoder (e.g., a MediaCodec decoder that handles FLAC (required from API level 27), or the FFmpeg extension with FLAC enabled). The DefaultExtractorsFactory uses the extension extractor if the application was built with the FLAC extension. Otherwise, it uses the core library extractor.

Using MediaItem

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

// Create a player instance.
ExoPlayer player = new ExoPlayer.Builder(context).build();
// Set the media item to be played.
// Prepare the player.

Using ProgressiveMediaSource

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

// 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)
// Create a player instance.
ExoPlayer player = new ExoPlayer.Builder(context).build();
// Set the media source to be played.
// Prepare the player.

Customizing playback

ExoPlayer provides multiple ways for you to tailor playback experience to your app’s needs. See the Customization page for examples.
