olly d3f4da749c Propagate track type through ExtractorOutput.track This allows binding by track type in ChunkExtractorWrapper, which allows the EMSG and 608 tracks to be enabled on FragmentedMp4Extractor in DefaultDashChunkSource. ChunkExtractorWrapper currently binds these to DummyTrackOutputs. Note: I wanted to pass the mimeType instead, since it's a more specific, but unfortunately there's at least one place where it's not known at the point of invoking track() (FlvExtractor).

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.
