  • Error merging two mp4 files using filter_complex [duplicate]

    3 août 2019, par Sumit Kumar

    This question already has an answer here :

    I am trying to merge/join 2 mp4 files using ffmpeg -filter_complex

    This is my command

    ffmpeg.exe -i a.mp4 -i b.mp4 -filter_complex "[0:v:0][0:a:0][1:v:0][1:a:0]concat=n=2:v=1:a=1[v][a]" -map "[v]" -map "[a]" output_video.mp4

    ffmpeg error :

  • Using and building FFMPEG library in Android Studio(Cmake)

    8 septembre 2017, par y3k00000

    As 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 {

            cFlags "-std=c99"
    
            cppFlags "-frtti","-fexceptions"
    
        }
    
    }
    
}
    
....

    By 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.
