Android NDK - 编译器找不到ffmpeg头文件

标签: android c++ ffmpeg android-ndk

我试图在实验性插件中使用带有Android NDK的ffmpeg库。

我正在尝试编译此示例: https://github.com/roman10/android-ffmpeg-tutorial/blob/master/android-ffmpeg-tutorial01/jni/tutorial01.c

我的问题是编译器找不到头文件:

Error:(13, 32) libavcodec/avcodec.h: No such file or directory

我为build.grade添加了标志:

cppFlags += "-ilibavcodec -ilibavutil -ilibavformat -ilibswscale"
ldFlags += "-llibavcodec -llibavutil -llibavformat -llibswscale"

这似乎让lint高兴,但不是编译器。 (不确定我是否做得对吗?)

我已将头文件添加到/ jni文件夹: Project folder structure

build.grade看起来像这样:

apply plugin: 'com.android.model.application'
model {
    android {
        compileSdkVersion = 23
        buildToolsVersion = "23.0.1"

        defaultConfig.with { 
            applicationId = "roman10.tutorial.android_ffmpeg_tutorial01"
            minSdkVersion.apiLevel = 10
            targetSdkVersion.apiLevel = 23

        }
    }

    compileOptions.with {
        sourceCompatibility = JavaVersion.VERSION_1_7
        targetCompatibility = JavaVersion.VERSION_1_7
    }

    android.buildTypes {
        release {
            minifyEnabled = false
            proguardFiles += file('proguard-rules.pro')
        }
    }


    android.ndk {
        moduleName = "tutorial01"
        ldLibs += ["android","log","jnigraphics","z"]
        cppFlags += "-ilibavcodec -ilibavutil -ilibavformat -ilibswscale"
        ldFlags += "-llibavcodec -llibavutil -llibavformat -llibswscale"
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-v4:23.0.1'
}

感谢。
