olly 2a8eb5a2a1 Make it easier to use ExoPlayer modules in other projects
It's currently difficult to use ExoPlayer modules in other gradle
projects because they rely on constants and dependencies defined
in our own top level gradle file. This change moves the constants
into a separate file referenced directly from each module. It also
removes the need for the top level gradle file to declare a
dependency on com.novoda:bintray-release. This is now only needed
if "exoplayerPublishEnabled = true" is specified.

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.
