龟速。。。。
虽说是张网红脸，但，曾经小的时候很可爱呀。。。。
官网下载地址相当龟速，github也时好时坏

External library support:
Using any of the following switches will allow FFmpeg to link to the
corresponding external library. All the components depending on that library
will become enabled, if all their other dependencies are met and they are not
explicitly disabled. E.g. --enable-libopus will enable linking to
libopus and allow the libopus encoder to be built, unless it is
specifically disabled with --disable-encoder=libopus.
Note that only the system libraries are auto-detected. All the other external
libraries must be explicitly enabled.

themselves, not all their features will necessarily be usable by FFmpeg.

SENRSL:ffmpeg senrsl$
准备工作应该是可以了。。。。
1，修改输出以生成so文件
ffmpeg从4.0版本开始直接支持 -target-os=android，不用再修改 configure文件；
2，创建编译脚本
本打算使用现有环境编译最新版 ffmpeg，看起来 莫名其妙的问题比较多，尤其是 android自从卖给google后一直走向作死的路上，还是单独下个 最新版本的ndk来编译最新版本的ffmpeg吧。。。。
SENRSL:ffmpeg senrsl$ sh ./build_android.sh
/Users/senrsl/android/android-ndk-r14b/toolchains/llvm/prebuilt/darwin-x86_64/bin/clang is unable to create an executable file.
C compiler test failed.
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.
Makefile:2: ffbuild/config.mak: No such file or directory
Makefile:40: /tools/Makefile: No such file or directory

应该没有比ThunderBird更傻的邮件客户端了吧。。。。
弱智级的。。。。
3，执行编译
执行build_android.sh，输出指定架构so
armeabi-v7a
arm64-v8a
x86
x86_64 编译这个的时候，默认会报错并输出x86，需要本地安装依赖库
4，搭建android项目导入so
抢茅台时间 2020年12月12日15:58:13
讲个笑话：github的主分支叫 main....
建一个android项目，勾选 cmake环境
复制 编译生成的 so到 libs目录，并配置build.gradle
4.1）复制so
libs目录，用哪个环境复制哪个就行，没必要全都复制一遍

4.2) build.gradle配置
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
android {
compileSdkVersion 29
buildToolsVersion "30.0.2"
defaultConfig {
applicationId "dc.test.ffmpeg"
minSdkVersion 19
targetSdkVersion 29
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
externalNativeBuild {
cmake {
cppFlags ""
}
}
ndkConfig.abiFilters 'armeabi-v7a'
}
externalNativeBuild {
cmake {
path "CMakeLists.txt"
}
}
sourceSets {
main {
jniLibs.srcDirs = ['libs']
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
}
dependencies {
implementation fileTree(dir: "libs", include: ["*.jar"])
implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
implementation 'androidx.core:core-ktx:1.3.2'
implementation 'androidx.appcompat:appcompat:1.2.0'
testImplementation 'junit:junit:4.12'
androidTestImplementation 'androidx.test.ext:junit:1.1.2'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'
implementation 'dc.common:logger:latest.integration'
implementation "dc.android:core:1.1.8"
implementation "dc.android:bridge:1.1.26"
implementation "dc.android.libs:permission:latest.integration"
}
一定要配置sourceSet，看起来现在的环境默认不是libs了，不配置这个找不到。。。。。
然后，复制include文件头，用来生成 指定平台so
4.3）复制文件头到cpp
SENRSL:test-ffmpeg senrsl$ tree -L 2 app/src/main/cpp/
app/src/main/cpp/
├── ffmpeg_utils.cpp
├── hello.c
└── include
├── libavcodec
├── libavdevice
├── libavfilter
├── libavformat
├── libavutil
├── libswresample
└── libswscale
8 directories, 2 files
SENRSL:test-ffmpeg senrsl$
随便建两个文件 hello.c和ffmpeg_utils.cpp用来测试通畅性。。。。
SENRSL:test-ffmpeg senrsl$ cat app/src/main/cpp/ffmpeg_utils.cpp
#include <stdio.h>
#include <jni.h>
extern "C" {
#include <libavutil/avutil.h>
JNIEXPORT jstring JNICALL
Java_dc_test_ffmpeg_Test01VersionActivity_getVersion(JNIEnv *env, jclass clazz) {
const char *version = av_version_info();
printf("getVersion is %s",version);
return env->NewStringUTF(version);
}
JNIEXPORT jstring JNICALL
Java_dc_test_ffmpeg_Test01VersionActivity_getVersion431(JNIEnv *env, jclass clazz) {
return env->NewStringUTF("4.3.1");
}
}SENRSL:test-ffmpeg senrsl$
然后配置 CMakeLists.txt，用来告诉cmake怎么编。。。。还是怀念eclipse写jni时代，现在封装的太恶心了。。。。
SENRSL:test-ffmpeg senrsl$ cat app/CMakeLists.txt
# 设置构建本机库文件所需的 CMake的最小版本
cmake_minimum_required(VERSION 3.4.1)
#添加头文件的搜索路径
include_directories(src/main/cpp/include)
#include_directories(src/main/cpp/ffmpeg/)
#设置查找动态库位置
set(LINK_DIR ${CMAKE_SOURCE_DIR}/libs/${CMAKE_ANDROID_ARCH_ABI})
link_directories(${LINK_DIR})
#找到所有的so库，存放在全局变量SO_DIR中
file(GLOB SO_DIR ${LINK_DIR}/*.so)
#找到所有的源文件，存放在全局变量中
#file(GLOB FFMPEG_DIR src/main/cpp/ffmpeg/*.c)
#message("FFMPEG_DIR == ${FFMPEG_DIR}")
file(GLOB CPP_DIR src/main/cpp/*.cpp)
file(GLOB FFMPEG_DIR src/main/cpp/include/*.c)
# 添加自己写的 C/C++源文件
add_library(utils #so名称
SHARED #动态库
${CPP_DIR}
${FFMPEG_DIR}
)
# 依赖 NDK中自带的log库
find_library(log-lib log)
# 链接库
target_link_libraries(
utils
${SO_DIR}
jnigraphics
${log-lib})SENRSL:test-ffmpeg
senrsl$
然后，so应该就可以正常生成了。。。。
写Activity跑跑
SENRSL:test-ffmpeg senrsl$ cat app/src/main/java/dc/test/ffmpeg/Test01VersionActivity.kt
package dc.test.ffmpeg
import android.content.Context
import android.content.Intent
import dc.android.base.activity.BridgeActivity
import dc.common.Logger
/**
*
*
* @ClassName: Test01VersionActivity
* @author senrsl
*
* @Package: dc.test.ffmpeg
* @CreateTime: 2020/12/12 5:44 下午
*/
class Test01VersionActivity : BridgeActivity() {
init {
System.loadLibrary("utils")
System.loadLibrary("avutil")
}
external fun getVersion(): String
external fun getVersion431(): String
companion object {
@JvmStatic
fun start(context: Context) {
val starter = Intent(context, Test01VersionActivity::class.java)
context.startActivity(starter)
}
}
override fun initLayout() {
super.initLayout()
}
override fun initData() {
super.initData()
// 2020-12-12 17:42:21.866 15060-15060/dc.test.ffmpeg W/TEST: 0：dc.test.ffmpeg.TestActivity
// 1：N-100400-g001bc594d8
// 2：4.3.1
Logger.w(this, javaClass.canonicalName, getVersion(), getVersion431())
}
}SENRSL:test-ffmpeg senrsl$
如果有输出，说明基本环境是可以了。。。。
就可以进入更深的坑了。。。。
