java.lang.UnsatisfiedLinkError: org.bytedeco.javacpp.avutil

[hseshadr]

[Using Android Studio (Jetbrains)]

1. Add Gradle dependencies to build.gradle

compile group: 'org.bytedeco', name: 'javacv', version: '1.1'
compile group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '2.8-1.1', classifier: 'android-arm'
compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '3.0.0-1.1', classifier:    'android-arm'

2. Download javacv-1.1-bin.zip from javacv site
3. unjar opencv-android-arm.jar
   copy opencv-android-arm/libarmeabi/_.lib to android project src/main/jniLibs/libarmeabi/
4. unjar ffmpeg-android-arm.jar
   copy ffmpeg-android-arm/libarmeabi/_.lib to android project src/main/jniLibs/libarmeabi/
5. In MainActivity onCreate invoke this method with a valid video file

    public void extractFrames(String filePath) {
        Frame frame = null;
        FFmpegFrameGrabber frameGrabber = new FFmpegFrameGrabber(filePath);
        try {
            frameGrabber.start();
            frame = frameGrabber.grab();
        } catch (FrameGrabber.Exception e) {
            e.printStackTrace();
        }
    }

Result:

Are you sure your device is not x86?

[saudet]

Could you try these SNAPSHOT binaries and let me know if they work any better?

@saudet, hi! I tried to use the links. But it did not help.
Error is the same on Marshmallow:
java.lang.UnsatisfiedLinkError: org.bytedeco.javacpp.avutil at java.lang.Class.classForName(Native Method) at java.lang.Class.forName(Class.java:324) at org.bytedeco.javacpp.Loader.load(Loader.java:446) at org.bytedeco.javacpp.Loader.load(Loader.java:411) at org.bytedeco.javacpp.avcodec$AVPacket.<clinit>(avcodec.java:1559) at org.bytedeco.javacv.FFmpegFrameRecorder.<init>(FFmpegFrameRecorder.java:149) at org.bytedeco.javacv.FFmpegFrameRecorder.<init>(FFmpegFrameRecorder.java:126)

Duplicate of #133. Try to put your libs in the "app/src/main/jniLibs/armeabi-v7a/" subdirectory instead.
