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
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 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.
