A DummySurface is useful with MediaCodec on API levels 23+. Rather than having to release a MediaCodec instance when the app no longer has a real surface to output to, it's possible to retain the MediaCodec, using MediaCodec.setOutputSurface to target a DummySurface instance instead. When the app has a real surface to output to again, it can call swap this surface back in instantaneously. Without DummySurface a new MediaCodec has to be instantiated at this point, and decoding can only start from a key-frame in the media. A future change may hook this up internally in MediaCodecRenderer for supported use cases, although this looks a little awkward. If this approach isn't viable, we can require applications wanting this to set a DummySurface themselves. This isn't easy to do with the way SimpleExoPlayerView.setPlayer works at the moment, however, so some changes will be needed either way.

ExoPlayer
ExoPlayer is an application level media player for Android. It provides an alternative to Android’s MediaPlayer API for playing audio and video both locally and over the Internet. ExoPlayer supports features not currently supported by Android’s MediaPlayer API, including DASH and SmoothStreaming adaptive playbacks. Unlike the MediaPlayer API, ExoPlayer is easy to customize and extend, and can be updated through Play Store application updates.
Documentation
- The developer guide provides a wealth of information to help you get started.
- The class reference documents the ExoPlayer library classes.
- The release notes document the major changes in each release.
Using ExoPlayer
The easiest way to get started using ExoPlayer is to add it as a gradle
dependency. You need to make sure you have the jcenter repository included in
the build.gradle file in the root of your project:
repositories {
jcenter()
}
Next add a gradle compile dependency to the build.gradle file of your app
module. The following will add a dependency to the full ExoPlayer library:
compile 'com.google.android.exoplayer:exoplayer:r2.X.X'
where r2.X.X is your preferred version. Alternatively, you can depend on only
the library modules that you actually need. For example the following will add
dependencies on the Core, DASH and UI library modules, as might be required for
an app that plays DASH content:
compile 'com.google.android.exoplayer:exoplayer-core:r2.X.X'
compile 'com.google.android.exoplayer:exoplayer-dash:r2.X.X'
compile 'com.google.android.exoplayer:exoplayer-ui:r2.X.X'
The available modules are listed below. Adding a dependency to the full ExoPlayer library is equivalent to adding dependencies on all of the modules individually.
exoplayer-core: Core functionality (required).exoplayer-dash: Support for DASH content.exoplayer-hls: Support for HLS content.exoplayer-smoothstreaming: Support for SmoothStreaming content.exoplayer-ui: UI components and resources for use with ExoPlayer.
For more details, see the project on Bintray. For information about the latest versions, see the Release notes.
Developing ExoPlayer
Project branches
- The project has
dev-vXandrelease-vXbranches, whereXis the major version number. - Most development work happens on the
dev-vXbranch with the highest major version number. Pull requests should normally be made to this branch. - Bug fixes may be submitted to older
dev-vXbranches. When doing this, the same (or an equivalent) fix should also be submitted to all subsequentdev-vXbranches. - A
release-vXbranch holds the most recent stable release for major versionX.
Using Android Studio
To develop ExoPlayer using Android Studio, simply open the ExoPlayer project in the root directory of the repository.
