no jniavdevice in java.library.path

[danybenjamin]

I am getting this error when running on ec2 runner but it works locally just fine.

my pom has:

 <dependency>
            <groupId>org.bytedeco</groupId>
            <artifactId>javacv-platform</artifactId>
            <version>1.5.4</version>
        </dependency>

        <dependency>

            <artifactId>javacv</artifactId>
            <version>1.5.4</version>
        </dependency>

        <dependency>
            <groupId>org.bytedeco</groupId>
            <artifactId>ffmpeg</artifactId>
            <version>4.3.1-1.5.4</version>
        </dependency>

The error:

Caused by: java.lang.UnsatisfiedLinkError: /root/.javacpp/cache/ffmpeg-4.3.1-1.5.4-linux-x86_64.jar/org/bytedeco/ffmpeg/linux-x86_64/libjniavdevice.so: libxcb.so.1: cannot open shared object file: No such file or directory

That's just a warning, you can ignore it.

It's not just a warning, it's failing my unit test and won't let keep going:

Why do you need avdevice if you don't have any devices installed??

[danybenjamin]

I don't? I'm not sure how to exclude that.

I tried with just this in my pom:

<dependency>
    <groupId>org.bytedeco</groupId>
    <artifactId>ffmpeg</artifactId>
    <version>4.3.1-1.5.4</version>
</dependency>

but then I get:

java.lang.UnsatisfiedLinkError: no jniavutil in java.library.path: [/Users/dany.benjamin/Library/Java/Extensions, /Library/Java/Extensions, /Network/Library/Java/Extensions, /System/Library/Java/Extensions, /usr/lib/java, .]

So, I saw another issue thread where you suggested adding the other two dependencies and with that, it worked locally on my mac.

[saudet]

Ok, so don't load avdevice explicitly and it will work fine.

[danybenjamin]

which package has avdevice?
which one should I exclude it from?

<dependency>
    <groupId>org.bytedeco</groupId>
    <artifactId>javacv-platform</artifactId>
    <version>1.5.4</version>
</dependency>

<dependency>
    <groupId>org.bytedeco</groupId>
    <artifactId>javacv</artifactId>
    <version>1.5.4</version>
</dependency>

[saudet]

It's part of FFmpeg, but you don't need to exclude anything. Just don't use its functions and you will be fine!

[danybenjamin]

I'm not using any function other than this:

 String ffmpeg = Loader.load(org.bytedeco.ffmpeg.ffmpeg.class);

        //ffmpeg -y -i <input> -c copy <output>
        ProcessBuilder pb = new ProcessBuilder(
            ffmpeg, "-y", "-i", workingDir + "/" + file, "-c", "copy", localFilePath);
        pb.inheritIO().start().waitFor();

I am not actively calling any other function for ffmpeg

[saudet]

Ah, I see, the ffmpeg program links with avdevice. If you really can't install libxcb, etc, the only way around that would probably be to build your own custom version of FFmpeg with these features disabled.

yum install alsa-lib-devel -y
