tonihei edbc2046e2 Clean-up manifest merge attributes.

1. Remove tools:replace in manifest files. This attribute is only needed to establish priority when two manifests are merged and have the same attribute with different values.
As this is not happening here, the attributes can be removed.

2. Some BUILD files also define a deprecated manifest merge strategy different from the android default merge strategy. For consistency these are set to "android'.

ExoPlayer Opus Extension

Description

The Opus Extension is a Renderer implementation that helps you bundle libopus (the Opus decoding library) into your app and use it along with ExoPlayer to play Opus 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="$(pwd)"
OPUS_EXT_PATH="${EXOPLAYER_ROOT}/extensions/opus/src/main"

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

NDK_PATH="<path to Android NDK>"

Fetch libopus:

cd "${OPUS_EXT_PATH}/jni" && \
git clone https://git.xiph.org/opus.git libopus

Run the script to convert arm assembly to NDK compatible format:

cd ${OPUS_EXT_PATH}/jni && ./convert_android_asm.sh

Build the JNI native libraries from the command line:

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

In your project, you can add a dependency to the Opus Extension by using a rule like this:

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

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

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

Notes

Every time there is a change to the libopus checkout:
- Arm assembly should be converted by running convert_android_asm.sh
- Clean and re-build the project.
If you want to use your own version of libopus, place it in ${OPUS_EXT_PATH}/jni/libopus.
