# 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.
[TrackRenderer]: https://google.github.io/ExoPlayer/doc/reference/com/google/android/exoplayer/TrackRenderer.html
## 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.
