olly 40f3f1cb78 Decrease number of Vpx input buffers

I think they're excessively sized also, but changing that
is a little more risky. And we should look at investigating
the input buffer size for all our decoder extensions,
rather than just this one.

Issue: #3120

FfmpegAudioRenderer

Description

The FFmpeg extension is a Renderer implementation that uses FFmpeg to decode audio.

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="$(pwd)"
FFMPEG_EXT_PATH="${EXOPLAYER_ROOT}/extensions/ffmpeg/src/main"

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

NDK_PATH="<path to Android NDK>"

Set up host platform ("darwin-x86_64" for Mac OS X):

HOST_PLATFORM="linux-x86_64"

Fetch and build FFmpeg. For example, to fetch and build for armeabi-v7a, arm64-v8a and x86 on Linux x86_64:

Build the JNI native libraries, setting APP_ABI to include the architectures built in the previous step. For example:

cd "${FFMPEG_EXT_PATH}"/jni && \
${NDK_PATH}/ndk-build APP_ABI="armeabi-v7a arm64-v8a x86" -j4
