Use of Sample objects was inefficient for several reasons: - Lots of objects (1 per sample, obviously). - When switching up bitrates, there was a tendency for all Sample instances to need to expand, which effectively led to our whole media buffer being GC'd as each Sample discarded its byte[] to obtain a larger one. - When a keyframe was encountered, the Sample would typically need to expand to accommodate it. Over time, this would lead to a gradual increase in the population of Samples that were sized to accommodate keyframes. These Sample instances were then typically underutilized whenever recycled to hold a non-keyframe, leading to inefficient memory usage. This CL introduces RollingBuffer, which tightly packs pending sample data into a byte[]s obtained from an underlying BufferPool. Which fixes all of the above. There is still an issue where the total memory allocation may grow when switching up bitrate, but we can easily fix that from this point, if we choose to restrict the buffer based on allocation size rather than time. Issue: #278
ExoPlayer Readme
Description
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 (as of KitKat), including DASH and SmoothStreaming adaptive playbacks, persistent caching and custom renderers. Unlike the MediaPlayer API, ExoPlayer is easy to customize and extend, and can be updated through Play Store application updates.
Developer guide
The ExoPlayer developer guide provides a wealth of information to help you get started.
Reference documentation
Class reference (Documents the ExoPlayer library classes).
Project branches
- The master branch holds the most recent minor release.
- Most development work happens on the dev branch.
- Additional development branches may be established for major features.
Using Eclipse
The repository includes Eclipse projects for both the ExoPlayer library and its accompanying demo application. To get started:
-
Install Eclipse and setup the Android SDK.
-
Open Eclipse and navigate to File->Import->General->Existing Projects into Workspace.
-
Select the root directory of the repository.
-
Import the ExoPlayerDemo and ExoPlayerLib projects.
Using Gradle
ExoPlayer can also be built using Gradle. You can include it as a dependent project and build from source. e.g.
// settings.gradle
include ':app', ':..:ExoPlayer:library'
// app/build.gradle
dependencies {
compile project(':..:ExoPlayer:library')
}
If you want to use ExoPlayer as a jar, run:
./gradlew jarRelease
and copy library.jar to the libs-folder of your new project.
