1. AudioDecoderTrackRenderer now reports decoder initialization and AudioTrack underruns. 2. AudioDecoderTrackRenderer can now render more than one output buffer per call to doSomeWork, to be consistent with MediaCodecAudioTrackRenderer. This may also prevent audio underruns in the case that audio is fragmented into many small buffers. 3. AudioDecoderTrackRenderer now has an overridable method that receives the audio session id, to be consistent with MediaCodecAudioTrackRenderer. 4. Fix unsafe event notification in LibvpxVideoTrackRenderer. 5. Vpx and AudioDecoder extensions now increment the CodecCounter inputBufferCount field correctly. 6. Decoders now have names :). ------------- Created by MOE: https://github.com/google/moe MOE_MIGRATED_REVID=122250009
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.
