一、配置远程 Maven 仓库

---

在 android Studio 工程 根目录的 build.gradle 构建脚本中 , 配置

repositories 
    mavenCentral()

完整代码如下 :

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript 
    ext.kotlin_version = "1.5.0"
    repositories 
        google()
        mavenCentral()
    
    dependencies 
        classpath "com.android.tools.build:gradle:4.2.1"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    


allprojects 
    repositories 
        google()
        mavenCentral()
        jcenter() // Warning: this repository is going to shut down soon
    


task clean(type: Delete) 
    delete rootProject.buildDir

二、配置依赖

---

在 Module 下的 build.gradle 构建脚本中配置依赖库 :

dependencies 
    implementation 'com.arthenica:mobile-ffmpeg-full:4.4'

完整代码如下 :

plugins 
    id 'com.android.application'
    id 'kotlin-android'


android 
    compileSdkVersion 31
    buildToolsVersion "30.0.3"

    defaultConfig 
        applicationId "kim.hsl.mobileffmpegdemo"
        minSdkVersion 24
        targetSdkVersion 31
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    

    buildTypes 
        release 
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        
    
    compileOptions 
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    
    kotlinOptions 
        jvmTarget = '1.8'
    


dependencies 

    implementation "org.jetbrains.kotlin:kotlin-stdlib:$kotlin_version"
    implementation 'androidx.core:core-ktx:1.6.0'
    implementation 'androidx.appcompat:appcompat:1.4.1'
    implementation 'com.google.android.material:material:1.5.0'
    implementation 'androidx.constraintlayout:constraintlayout:2.1.3'
    testImplementation 'junit:junit:4.+'
    androidTestImplementation 'androidx.test.ext:junit:1.1.3'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'

    implementation 'com.arthenica:mobile-ffmpeg-full:4.4'

三、Kotlin 中执行 FFmpeg 命令

---

在 kotlin 代码中调用 mobile-ffmpeg 框架中提供的 执行 FFmpeg 命令的方法 :

执行的 FFmpeg 命令为 :

ffmpeg -version

完整代码如下 :

package kim.hsl.mobileffmpegdemo

import android.os.Bundle
import android.util.Log
import androidx.appcompat.app.AppCompatActivity
import com.arthenica.mobileffmpeg.Config
import com.arthenica.mobileffmpeg.FFmpeg


class MainActivity : AppCompatActivity() 
    override fun onCreate(savedInstanceState: Bundle?) 
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)


        val rc = FFmpeg.execute("-version")

        if (rc == Config.RETURN_CODE_SUCCESS) 
            Log.i(Config.TAG, "命令执行成功")
         else if (rc == Config.RETURN_CODE_CANCEL) 
            Log.i(Config.TAG, "用户取消了命令")
         else 
            Log.i(Config.TAG, String.format("命令执行失败, 返回值=%d", rc))
        

        Config.printLastCommandOutput(Log.INFO)
    

四、FFmpeg 命令执行结果查看

---

执行结果如下 : 在 华为 Mate30 中 , 对应 Android 10 系统版本也可以执行 ;
