Progressive

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). For image container and format support, see Images.

Container format	Supported	Comments
MP4	YES
M4A	YES
FMP4	YES
WebM	YES
Matroska	YES
MP3	YES	Some streams only seekable using constant bitrate seeking**
Ogg	YES	Containing Vorbis, Opus and FLAC
WAV	YES
MPEG-TS	YES
MPEG-PS	YES
FLV	YES	Not seekable*
ADTS (AAC)	YES	Only seekable using constant bitrate seeking**
FLAC	YES	Using the FLAC library or the FLAC extractor in the ExoPlayer library***
AMR	YES	Only seekable using constant bitrate seeking**

* 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.

*** The FLAC library extractor outputs raw audio, which can be handled by the framework on all API levels. The ExoPlayer library 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 with FLAC enabled). The DefaultExtractorsFactory uses the extension extractor if the application was built with the FLAC library. Otherwise, it uses the ExoPlayer library extractor.

Using MediaItem

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

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

// 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();

Using ProgressiveMediaSource

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

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

// 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 for examples.
