"java.lang.UnsatisfiedLinkError: dlopen failed: library "libavfilter.so" not found" when running on Android Dynamic FeatureModule

[carlosandre-br]

Description The library works perfectly in my environment, but when I try to run it on a dynamic module, I'm getting java.lang.UnsatisfiedLinkError: dlopen failed: library "libavfilter.so" not found.

Expected behavior Run the library in a dynamic feature module.

Current behavior The library crashes when it calls System.loadLibrary("mobileffmpeg");

Environment

• Platform: Android [Edited]
• Architecture: arm64-v8a
• Version mobile-ffmpeg-min - 4.4.LTS
• Android Studio version: 4.1.1

Other In Debug mode the app works fine.

But when I installed as App Bundle, I got the error.

Steps I did:

1. Create Android app with compileSdkVersion 29 and targetSdkVersion 29
2. Create dynamic feature module in Android Studio
3. Add the implementation group: 'com.arthenica', name: 'mobile-ffmpeg-min', version: '4.4.LTS' to the new module
4. Generate a signed App Bundle (AAB)
5. Install the base APK using the Android Bundle tool as following:

sudo java -jar bundletool-all-1.4.0.jar build-apks --local-testing --bundle /path/to/app-release.aab --output /path/to/output.apks

sudo java -jar bundletool-all-1.4.0.jar install-apks --apks /path/to/output.apks

6. In the app, request a feature module installation
7. After dynamic module installation, call long executionId = FFmpeg.executeAsync("-version", new ExecuteCallback() {...}); and it throw an error.

There are similar issues created for UnsatisfiedLinkError recently. Have you looked at them?

[carlosandre-br]

Yes I did, but none of them referred to the problem with dynamic delivery specifically. I solved it by loading the libraries using SplitInstallHelper.loadLibrary(Context,String) after module installation. This way:

 @Override
    public void onStateUpdate(SplitInstallSessionState state) {
        if (state.sessionId() == sessionId) {
            switch (state.status()) {
                case INSTALLED:
                    statusText.setText("Installed - Feature is ready");
                    SplitInstallHelper.loadLibrary(this, "avutil");
                    SplitInstallHelper.loadLibrary(this, "swscale");
                    SplitInstallHelper.loadLibrary(this, "swresample");
                    SplitInstallHelper.loadLibrary(this, "avcodec");
                    SplitInstallHelper.loadLibrary(this, "avformat");
                    SplitInstallHelper.loadLibrary(this, "avfilter");
                    SplitInstallHelper.loadLibrary(this, "avdevice");
                    break;
            }
        }
    }

Thank you!

@carlosandre-br Thanks for the answer

i am getting "java.lang.UnsatisfiedLinkError: dlopen failed: library "libavfilter.so" not found" @carlosandre-br I tried your code but it's not working for me! does FakeSplitInstallManagerFactory is necessary if you testing a dynamic feature module locally?

Version mobile-ffmpeg-audio - 4.4.LTS

Hello @iamkdblue!

It's not necessary to use FakeSplitInstallManagerFactory to test success cases.

I'm attaching a demo project that's working, please check DynamicDemo.zip and compare with yours.

@carlosandre-br finally it solved now, Thank you so much, your project helps me a lot. You should put the above project on GitHub, it will help many people
