Running multiple commands on FFMPEG Android Studio
2 juin 2016, par Ali AsheerI have compiled https://github.com/WritingMinds/ffmpeg-android-java on my Android Studio and it’s working fine, i have successfully executed these 3 commands :
Adding text :
new String[]={"-i",file1.toString(), "-i", water,"-filter_complex","drawtext=fontsize=60:fontfile=/system/fonts/DroidSans.ttf:fontcolor=green:text=AAAA:x=(w-tw)/2:y=(50-th)/2", final_output}
Adding Watermark :
new String[]{"-i",inputVideoFilePath, "-i",overlayImagePath,"-preset", "ultrafast","-filter_complex", "overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2", "-codec:a", "copy", outputVideoFilePath
Add Padding :
new String[]{"-i",file1.toString(), "-i", water,"-filter_complex","[0:v]pad=iw:ih+100:0:(oh-ih)/2:color=white", final_output2};
Now i want to combine these three how do i accomplish that ? So far i have tried padding with text :
new String[]{"-i",file1.toString(), "-i", water,"-filter_complex","[0:v]pad=iw:ih+100:0:(oh-ih)/2:color=white","drawtext=fontsize=60:fontfile=/system/fonts/DroidSans.ttf:fontcolor=green:text=AAAA:x=(w-tw)/2:y=(50-th)/2", final_output2};
But i get this error :
Input #1, png_pipe, from '/storage/emulated/0/watermark.png':
Duration: N/A, bitrate: N/A
Stream #1:0: Video: png, rgb24(pc), 200x125, 25 tbr, 25 tbn, 25 tbc

drawtext=fontsize=60:fontfile=/system/fonts/DroidSans.ttf:fontcolor=green:text=AAAA:x=(w-tw)/2:y=(50-th)/2: Invalid argumentAny kind of help would be great !

Using and building FFMPEG library in Android Studio(Cmake)
8 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.
