UnsatisfiedLinkError: org.bytedeco.javacpp.avutil #8

JoyHong · 2016-10-26T02:29:41Z

Dear

Now, i'm using latest code, but in some platform(eg. Meizu 6.0+), it crash with following message.
I don't know how to handle it...

Will this error occur on those platforms if you set targetSdkVersion to 22?

JoyHong · 2016-10-27T00:56:13Z

Yes, when i set targetSdkVersion to 22, this issue still occur.

CrazyOrr · 2016-10-27T10:24:22Z

Check out this and this.
P.S. You can use this tool to see if those .so libraries are available on your device.

JoyHong · 2016-10-28T02:07:57Z

Dear
I checked with the tool
In the devices work well, it supprot arm64-v8a, armeabi-v7a, armeabi.
In the devices occur crash, it only support armeabi-v7a, armeabi.
Could u please help to support it for me?

CrazyOrr · 2016-10-28T06:42:45Z

I'll look into it, but I don't think arm64-v8a is the problem here. Because on my Nexus 6, which only supports armeabi-v7a and armeabi, this error doesn't occur.

hexmonad · 2016-10-28T07:21:26Z

Hi @JoyHong ,
did you try a manual installation: https://github.com/bytedeco/javacv#manual-installation ?
This is done in this commit: 2ab86b6
Please check it out.

JoyHong · 2016-10-28T09:14:45Z

btw, does following configuration will effect the result?
ndk {
abiFilters 'armeabi'
}

hexmonad · 2016-10-28T09:59:14Z

Yes, it does. From https://developer.android.com/studio/projects/add-native-code.html:

By default, Gradle builds your native library into separate .so files for the ABIs the NDK supports and packages them all into your APK. If you want Gradle to build and package only certain ABI configurations of your native libraries, you can specify them with the ndk.abiFilters flag in your module-level build.gradle file

So, if you use "abiFilters 'armeabi'", you should place .so files in the app/src/main/jniLibs/armeabi folder.

CrazyOrr · 2016-10-28T10:12:23Z

I don't think so because there are only armeabi libraries, so you don't need to specify that.

hexmonad · 2016-10-28T10:28:59Z

When you use the tool mentioned here: #8 (comment),
do you see libraries under Native Libraries Installed section, like libavutil.so etc. ?

JoyHong · 2016-10-28T13:35:03Z

Yes, I saw them
but, I check the list is the same with my two devices.

tingfengainiaini · 2016-11-01T02:48:36Z

Relinker works for me.

JoyHong · 2016-11-01T05:43:56Z

Dear, help me, sorry for my poor knowledge.
Now i got aother crash log, Caused by: java.lang.NoClassDefFoundError: org/bytedeco/javacpp/avutil
I follow the doc to manully in manual-installation, but i can't find any jar files in the javacpp-presets-1.2-bin or javacpp-presets-1.2-src, should i need to compile them?

CrazyOrr · 2016-11-01T05:58:38Z

You should download javacv-1.2-bin.zip, and unzip xx-android-arm/x86.jar in it to get .so files.

JoyHong · 2016-11-01T06:41:36Z

Hi
Should i add ffmpeg-android-arm.jar and opencv-android-arm.jar to libs
and remove following configuations?

configurations {
all*.exclude group: 'org.bytedeco', module: 'javacpp-presets'
}
compile group: 'org.bytedeco', name: 'javacpp', version: '1.2.4'
compile(group: 'org.bytedeco', name: 'javacv', version: '1.2') {
exclude group: 'org.bytedeco.javacpp-presets'
}
compile group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '3.0.2-1.2'
compile group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '3.0.2-1.2', classifier: 'android-arm'

CrazyOrr · 2016-11-01T11:19:17Z

No, ffmpeg-android-arm.jar = compile group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '3.0.2-1.2', classifier: 'android-arm', and opencv-android-arm.jar is not needed.
You need to put javacpp.jar, javacv.jar, ffmpeg.jar, ffmpeg-android-arm.jar in libs.

JoyHong · 2016-11-02T01:05:19Z

Dear CrazyOrr
It still not work in some devices.
but, i found that these devices are 32bit, i suppose it's the key point.
How can i specify use 32bit so?

JoyHong · 2016-11-02T02:44:37Z

I install your project to 32bit device, the same crash will occurs

Could u please help to solve it asap?

JoyHong · 2016-11-02T03:25:34Z

Sorry, correct, it not depends 32bit
Meizu 64bit still occurs this crash.....

tingfengainiaini · 2016-11-21T12:26:17Z

@JoyHong
I have encoutered this today again in Meizu note 3, with javacv1.2. javacpp1.2.4, javacpp presets 1.2.
I used javacv in a sub module of my project, not app module. This time, the relinker did no help.
When I move the relinker function into main ui thread, mainactivity's onCreate for example. It works!
But I have not test other phones yet.
Add these codes in your main ui thread (add relinker in your gradle first). Hope this works for you.

        ReLinker.log(logger).recursively().loadLibrary(this, "avdevice");
        ReLinker.log(logger).recursively().loadLibrary(this, "avfilter");
        ReLinker.log(logger).recursively().loadLibrary(this, "avformat");
        ReLinker.log(logger).recursively().loadLibrary(this, "jniavutil");
        ReLinker.log(logger).recursively().loadLibrary(this, "avutil");
        ReLinker.log(logger).recursively().loadLibrary(this, "postproc");
        ReLinker.log(logger).recursively().loadLibrary(this, "swscale");
        ReLinker.log(logger).recursively().loadLibrary(this, "swresample");
        ReLinker.log(logger).recursively().loadLibrary(this, "jniavdevice");
        ReLinker.log(logger).recursively().loadLibrary(this, "jniavfilter");
        ReLinker.log(logger).recursively().loadLibrary(this, "jniavformat");
        ReLinker.log(logger).recursively().loadLibrary(this, "jnipostproc");
        ReLinker.log(logger).recursively().loadLibrary(this, "jniswresample");
        ReLinker.log(logger).recursively().loadLibrary(this, "jniswscale");
        ReLinker.log(logger).recursively().loadLibrary(this, "jniavcodec");
        ReLinker.log(logger).recursively().loadLibrary(this, "avcodec");

Add: (2016/11/25)
You should clean your project when updating the native library, if you use AS! Remeber!
