        <artifactId>ffmpeg</artifactId>
        <version>3.0.2-1.2</version>
    </dependency>

    <dependency>

        <artifactId>opencv</artifactId>
        <version>3.1.0-1.2</version>
    </dependency>

    <dependency>

        <artifactId>javacpp</artifactId>
        <version>0.10</version>
    </dependency>

Answer 1

First problem

Your versions don't match. org.bytedeco.javacpp in version 0.10 is from Dec 2014, while all your other versions are from May 2016. You need to use version 1.2 of org.bytedeco.javacpp, or better yet, update all dependencies to the latest version.

You can see the versions here:

org.bytedeco.javacpp-presets » opencv

org.bytedeco.javacpp-presets » ffmpeg

org.bytedeco » javacv

org.bytedeco » javacpp

Second problem

You include the dependencies for Java code only, but you don't include the dependencies for native code (both opencv and ffmpeg are native libraries). You need to include opencv-platform and ffmpeg-platform instead:

<dependency>
    <groupId>org.bytedeco</groupId>
    <artifactId>javacpp</artifactId>
    <version>1.4.1</version>
</dependency>
<dependency>
    <groupId>org.bytedeco</groupId>
    <artifactId>javacv</artifactId>
    <version>1.4.1</version>
</dependency>
<dependency>
    <groupId>org.bytedeco.javacpp-presets</groupId>
    <artifactId>opencv-platform</artifactId>
    <version>3.4.1-1.4.1</version>
</dependency>
<dependency>
    <groupId>org.bytedeco.javacpp-presets</groupId>
    <artifactId>ffmpeg-platform</artifactId>
    <version>3.4.2-1.4.1</version>
</dependency>

This will make Maven download and include opencv and ffmpeg libraries for Android, Linux, MacOS and Windows, both x86 and x64.
