Release notes

r2.0.0

ExoPlayer 2.x is a major iteration of the library. It includes significant API and architectural changes, new features and many bug fixes. You can read about some of the motivations behind ExoPlayer 2.x here.

  • Root package name changed to com.google.android.exoplayer2. The library structure and class names have also been sanitized. Read more here.
  • Key architectural changes:
  • Late binding between rendering and media source components. Allows the same rendering components to be re-used from one playback to another. Enables features such as gapless playback through playlists and DASH multi-period support.
  • Improved track selection design. More details can be found here.
  • LoadControl now used to control buffering and loading across all playback types.
  • Media source components given additional structure. A new MediaSource class has been introduced. MediaSources expose Timelines that describe the media they expose, and can consist of multiple MediaPeriods. This enables features such as seeking in live playbacks and DASH multi-period support.
  • Responsibility for loading the initial DASH/SmoothStreaming/HLS manifest is promoted to the corresponding MediaSource components and is no longer the application's responsibility.
  • Higher level abstractions such as SimpleExoPlayer have been added to the library. These make the library easier to use for common use cases. The demo app is halved in size as a result, whilst at the same time gaining more functionality. Read more here.
  • Enhanced library support for implementing audio extensions. Read more here.
  • Format and MediaFormat are replaced by a single Format class.
  • Key new features:
  • Playlist support. Includes support for gapless playback between playlist items and consistent application of LoadControl and TrackSelector policies when transitioning between items (#1270).
  • Seeking in live playbacks for DASH and SmoothStreaming (#291).
  • DASH multi-period support (#557).
  • MediaSource composition allows MediaSources to be concatenated into a playlist, merged and looped. Read more here.
  • Looping support (see above) (#490).
  • Ability to query information about all tracks in a piece of media (including those not supported by the device) (#1121).
  • Improved player controls.
  • Support for PSSH in fMP4 moof atoms (#1143).
  • Support for Opus in Ogg (#1447).
  • CacheDataSource support for standalone media file playbacks (mp3, mp4 etc).
  • FFMPEG extension (for audio only).
  • Key bug fixes:
  • Removed unnecessary secondary requests when playing standalone media files (#1041).
  • Fixed playback of video only (i.e. no audio) live streams (#758).
  • Fixed silent failure when media buffer is too small (#583).
