aquilescanta 2f4bfc3f5f Add the TrackSelectionPolicy to decouple track "assignment" and selection

Allows the user to provide their own criteria for selecting one of the available tracks
without having to reimplement the track assignment logic, i.e. linking type x tracks with
type x renderer.

ExoPlayer VP9 Extension

Description

The VP9 Extension is a TrackRenderer implementation that helps you bundle libvpx (the VP9 decoding library) into your app and use it along with ExoPlayer to play VP9 video 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="$(pwd)"
VP9_EXT_PATH="${EXOPLAYER_ROOT}/extensions/vp9/src/main"

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

NDK_PATH="<path to Android NDK>"

Fetch libvpx and libyuv:

cd "${VP9_EXT_PATH}/jni" && \
git clone https://chromium.googlesource.com/webm/libvpx libvpx && \
git clone https://chromium.googlesource.com/libyuv/libyuv libyuv

Run a script that generates necessary configuration files for libvpx:

cd ${VP9_EXT_PATH}/jni && \
./generate_libvpx_android_configs.sh "${NDK_PATH}"

Build the JNI native libraries from the command line:

cd "${VP9_EXT_PATH}"/jni && \
${NDK_PATH}/ndk-build APP_ABI=all -j4

In your project, you can add a dependency to the VP9 Extension by using a the following rule:

// in settings.gradle
include ':..:ExoPlayer:library'
include ':..:ExoPlayer:extension-vp9'

// in build.gradle
dependencies {
    compile project(':..:ExoPlayer:library')
    compile project(':..:ExoPlayer:extension-vp9')
}

Now, when you build your app, the VP9 extension will be built and the native libraries will be packaged along with the APK.

Notes

Every time there is a change to the libvpx checkout:
- Android config scripts should be re-generated by running generate_libvpx_android_configs.sh
- Clean and re-build the project.
If you want to use your own version of libvpx or libyuv, place it in ${VP9_EXT_PATH}/jni/libvpx or ${VP9_EXT_PATH}/jni/libyuv respectively.
