Record Activity was crashed after initializing recorded video

Hi Saudet,

I'm trying to run the record activity in your javacv-1.2-src.zip, but when I clicked on Start button, the app has stopped.

My logcat:

My build.gradle:

configurations {
    all*.exclude group: 'org.bytedeco', module: 'javacpp-presets'
}

repositories {
    mavenCentral()
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.0.0-beta1'

    compile group: 'org.bytedeco', name: 'javacv', version: '1.2'
}

I've changed something:

private String ffmpeg_link;
private String outputDir = "/KKTTesting";
...
@Override
public void onCreate(Bundle savedInstanceState) {
...
          new File(Environment.getExternalStorageDirectory(), outputDir).mkdir();
          ffmpeg_link = Environment.getExternalStorageDirectory() + outputDir + "/recordedVideo.flv";
}

I tested it on Android 6.0 and I'm using android studio.
