ExoPlayer+FFMpeg软解
概述
ExoPlayer是Google开源的Android平台媒体播放器。 它是Android的MediaPlayer API的替代品。
相⽐于IJKPlayer,EXOPlayer更易于拓展，功能更多，bug更少。ExoPlayer虽然不⽀持软解但是为开发者扩展软解预留了接⼝。⽹上竟然搜不到ExoPlayer+软解的扩展实现，那就有必要来⼀篇了hhh。

4.根据要编译的架构编写编译脚本
ANDROID_NDK=/Users/hawkswang/ndk/android-ndk-r15c
HOST_PLATFORM=darwin-x86_64
./configure \
--libdir=android-libs/armeabi-v7a \
--arch=arm \
--cpu=armv7-a \
--cross-prefix="${ANDROID_NDK}/toolchains/arm-linux-androideabi-4.9/prebuilt/${HOST_PLATFORM}/bin/arm-linux-androideabi-" \
--sysroot="${ANDROID_NDK}/platforms/android-9/arch-arm/" \
--extra-cflags="-march=armv7-a -mfloat-abi=softfp" \
--extra-ldflags="-Wl,--fix-cortex-a8" \
--extra-ldexeflags=-pie \
${COMMON_OPTIONS} \
5.开始编译
make -j4 && make install-libs
6.编写JNI（如果想要扩展更多功能的话）
7.交叉编译JNI接⼝
在⽬录下ExoPlayer/extensions/ffmpeg/src/main/jni
执⾏
ANDROID_NDK=/Users/hawkswang/ndk/android-ndk-r15c
HOST_PLATFORM=darwin-x86_64
${ANDROID_NDK}/ndk-build APP_ABI="armeabi armeabi-v7a arm64-v8a" -j4
下⾯是把第1～5部整合到⼀块的脚本；
#!/bin/bash
ANDROID_NDK=/Users/hawkswang/ndk/android-ndk-r15c
