The allocator and buffering policy (e.g. how large the buffer is) is moving to the top level as part of playlist support, so it no longer makes sense to inject these parameters as args into ExtractorSampleSource's constructor. Instantiating the allocator and buffer size inside of the source is temporary and only until they're moved up. ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=123968976
ExoPlayer Flac Extension
Description
The Flac Extension is a TrackRenderer 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.
