  • Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

    8 février 2011, par

    La visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
    Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

  • While working with ffmpeg : Created function in C file and after compilation with NDK accessing from android activity, getting signal 11 error

    30 mai 2016, par Dayanand Lande

    After successfully fire command ndk-build I got .so file in my libs folder, then after some changes in gradle file I got native_libs.xml .idea/libraries folder.

    Now I am accessing c function from my java code/ android activity. I am getting signal 11 error

    My code is

    C file

    #include 
    
#include <android></android>log.h>
    
#include 
    

    
#include "libavcodec/avcodec.h"
    
#include "libavformat/avformat.h"
    

    
#define LOG_TAG "mylib"
    
#define LOGI(...)  __android_log_print(ANDROID_LOG_INFO, LOG_TAG, __VA_ARGS__)
    
#define LOGE(...)  __android_log_print(ANDROID_LOG_ERROR, LOG_TAG, __VA_ARGS__)
    

    

    
//JNIEXPORT jint JNICALL Java_com_xxx_xxx_activities_SplashActivity_logFileInfo(JNIEnv * env, jobject this, jstring filename);
    

    
jint Java_com_xxx_xxx_activities_TutorialsActivity_logFileInfo(JNIEnv * env, jobject this, jstring filename)
    
{
    
    av_register_all();
    

    
    AVFormatContext *pFormatCtx;
    
    const jbyte *str;
    
    str = (*env)->GetStringUTFChars(env, filename, NULL);
    

    
    if(avformat_open_input(&amp;pFormatCtx, str, NULL, NULL)!=0)
    
    {
    
        LOGE("Can't open file '%s'\n", str);
    
        return 1;
    
    }
    
    else
    
    {
    
        LOGI("File was opened\n");
    
        LOGI("File '%s', Codec %s",
    
            pFormatCtx->filename,
    
            pFormatCtx->iformat->name
    
        );
    
    }
    
    return 0;
    
}

    Loading and try to access method in java code is

    private static native int logFileInfo(String filename);
    

    

    
    static {
    
        System.loadLibrary("framegrabber");
    
    }

    In OnCreate of activity

    logFileInfo(file.getAbsolutePath());

    Finally error at point logFileInfo(file.getAbsolutePath()); is

    A/libc: Fatal signal 11 (SIGSEGV), code 1, fault addr 0x106e in tid 8905 (Thread-20972)

    Please replay if you have any solution, Thanking in advance.

  • A/libc : Fatal signal 11 (SIGSEGV), code 1, fault addr 0x0

    16 mai 2016, par Pedro

    I’m working with javacv and when I try run my app with Android 6, it crashes.
    The app only crash with android 6. I tested with android N, android 5 and android 4.4
    the app crash when do a instance of FFmpegFrameRecorder class.
    This is the code of my class :

    public class MainActivity extends Activity{
    

    
  @Override
    
  protected void onCreate(Bundle savedInstanceState) {
    
    super.onCreate(savedInstanceState);
    
    setContentView(R.layout.activity_main);
    

    
    new FFmpegFrameRecorder("", 320, 240, 1);
    
  }
    
}

    this is my log error :
