Android Java — Using and building FFMPEG library in Android Studio(Cmake)
12 septembre 2017, par y3k00000As title, I’m trying to use the ffmpeg source code as library in Android Studio on Ubuntu Linux, but meeting some trouble in compilation stage. I think I must be missing some compile option but having no idea what I miss, can somebody lend a hand ?
My codes & settings are below :
A simple auto-generated .cpp
#include
#include <string>
#include "libavcodec/aacenc.h"
extern "C"
JNIEXPORT jstring JNICALL
Java_y3k_testffmpegnative_MainActivity_stringFromJNI(
JNIEnv *env,
jobject /* this */) {
std::string hello = "Hello from C++";
return env->NewStringUTF(hello.c_str());
}
AACEncContext * aacEncContext; // Just trying by adding this.
</string>I’ve tried these Gradle setting and it didn’t help :
android {
....
externalNativeBuild {
cmake {
arguments "-DANDROID_TOOLCHAIN=clang"
cFlags "-std=c99"
cppFlags "-frtti","-fexceptions"
}
}
}
....CMakeLists.txt
(Android Studio generated)
....

build_oneBy tracing the errors I found these lines :
in float_dsp.h, fixed_dsp.h :
void (*butterflies_float)(float *av_restrict v1, float *av_restrict v2, int len);
av_restrict defined in config.h
#define av_restrict restrict
in aac.h :
....
struct AACContext {
AVClass *class;
....in mpeg4audio.h :
extern av_export const int avpriv_mpeg4audio_sample_rates[16];
So I’m guessing it’s because the compiler misrecognized the C code as C++, I tried adding these :
arguments "-DANDROID_TOOLCHAIN=clang"
cFlags "-std=c99"to my build.gradle but didn’t help. Having no idea where to move on. :(
I’m using the latest stable version of Android Studio on Ubuntu desktop. Please don’t be hesitate to ask if any extra information is required.
Also I’ve been tried edit my native-lib.cpp into .c (Surely with the code contents changed), but wasn’t working either.
Appreciate for any help.
