ExoPlayer Flac Extension

Description

The Flac Extension is a Renderer implementation that helps you bundle libFLAC (the Flac decoding library) into your app and use it along with ExoPlayer to play Flac audio on Android devices.

Build Instructions

• Checkout ExoPlayer along with Extensions:

git clone https://github.com/google/ExoPlayer.git

• Set the following environment variables:

cd "<path to exoplayer checkout>"
EXOPLAYER_ROOT="$(pwd)"
FLAC_EXT_PATH="${EXOPLAYER_ROOT}/extensions/flac/src/main"

• Download the Android NDK and set its location in an environment variable:

NDK_PATH="<path to Android NDK>"

• Download and extract flac-1.3.1 as "${FLAC_EXT_PATH}/jni/flac" folder:

cd "${FLAC_EXT_PATH}/jni" && \
curl http://downloads.xiph.org/releases/flac/flac-1.3.1.tar.xz | tar xJ && \
mv flac-1.3.1 flac

• Build the JNI native libraries from the command line:

cd "${FLAC_EXT_PATH}"/jni && \
${NDK_PATH}/ndk-build APP_ABI=all -j4

• In your project, you can add a dependency to the Flac Extension by using a rule like this:

// in settings.gradle
include ':..:ExoPlayer:library'
include ':..:ExoPlayer:extension-flac'

// in build.gradle
dependencies {
    compile project(':..:ExoPlayer:library')
    compile project(':..:ExoPlayer:extension-flac')
}

• Now, when you build your app, the Flac extension will be built and the native libraries will be packaged along with the APK.
