ExoPlayer VP9 Extension

Description

The VP9 Extension is a Renderer 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

To use this extension you need to clone the ExoPlayer repository and depend on its modules locally. Instructions for doing this can be found in ExoPlayer's top level README. In addition, it's necessary to build the extension's native components as follows:

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

Checkout the appropriate branches of libvpx and libyuv (the scripts and makefiles bundled in this repo are known to work only at these versions of the libraries - we will update this periodically as newer versions of libvpx/libyuv are released):

cd "${VP9_EXT_PATH}/jni/libvpx" && \
git checkout tags/v1.6.1 -b v1.6.1 && \
cd "${VP9_EXT_PATH}/jni/libyuv" && \
git checkout 996a2bbd

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

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. But please note that generate_libvpx_android_configs.sh and the makefiles need to be modified to work with arbitrary versions of libvpx and libyuv.
