1Streams in the following container formats can be played directly by ExoPlayer. 2The contained audio and video sample formats must also be supported (see the 3[sample formats](supported-formats.html#sample-formats) section for details). 4 5| Container format | Supported | Comments | 6|------------------|:------------:|:---------------------| 7| MP4 | YES || 8| M4A | YES || 9| FMP4 | YES || 10| WebM| YES || 11| Matroska| YES || 12| MP3 | YES | Some streams only seekable using constant bitrate seeking** | 13| Ogg | YES | Containing Vorbis, Opus and FLAC | 14| WAV | YES || 15| MPEG-TS | YES || 16| MPEG-PS | YES || 17| FLV | YES | Not seekable* | 18| ADTS (AAC) | YES | Only seekable using constant bitrate seeking** | 19| FLAC | YES | Using the [FLAC extension][] or the FLAC extractor in the [core library][]*** | 20| AMR | YES | Only seekable using constant bitrate seeking** | 21| JPEG motion photo | YES | Only the MP4 content is extracted | 22 23\* Seeking is unsupported because the container does not provide metadata (e.g., 24a sample index) to allow a media player to perform a seek in an efficient way. 25If seeking is required, we suggest using a more appropriate container format. 26 27\*\* These extractors have `FLAG_ENABLE_CONSTANT_BITRATE_SEEKING` flags for 28enabling approximate seeking using a constant bitrate assumption. This 29functionality is not enabled by default. The simplest way to enable this 30functionality for all extractors that support it is to use 31`DefaultExtractorsFactory.setConstantBitrateSeekingEnabled`, as described 32[here](customization.html#enabling-constant-bitrate-seeking). 33 34\*\*\* The [FLAC extension][] extractor outputs raw audio, which can be handled 35by the framework on all API levels. The [core library][] FLAC extractor outputs 36FLAC audio frames and so relies on having a FLAC decoder (e.g., a `MediaCodec` 37decoder that handles FLAC (required from API level 27), or the 38[FFmpeg extension][] with FLAC enabled). The `DefaultExtractorsFactory` uses the 39extension extractor if the application was built with the [FLAC extension][]. 40Otherwise, it uses the [core library][] extractor. 41 42[FLAC extension]: {{ site.release_v2 }}/extensions/flac 43[core library]: {{ site.release_v2 }}/library/core 44[FFmpeg extension]: {{ site.release_v2 }}/extensions/ffmpeg 45
