Wowza.GoCoder not working with org.bytedeco.javacv.FFmpegFrameRecorder

问题

I am working with code from https://github.com/bytedeco/sample-projects/blob/master/JavaCV-android-example/app/src/main/java/org/bytedeco/javacv_android_example/record/RecordActivity.java. Demo working fine

I want to use wowza.gocoder with FFmpeg so by only add wowza dependancy in app.gradle then demo application crash at run time as screenshot

here is my app.gradle file

apply plugin: 'com.android.application'

    compileSdkVersion 29

So finally, there is an issue, but with merging dependencies inside project. To start first, issue with linking native sources, and for some implementation, it's not possible to find native methods, which could be changed, because this resource get updated in scope of other library, which use latest version of it.

To make sure, it's an issue, you need to check dependencies in project with ./gradlew app:dependencies. And double check, that something similar could be found in the com.wowza.gocoder.sdk.android and org.bytedeco.*.

And to resolve it, need to configure ResolutionStrategy by changing some options for one or another library, based on their dependency tree.

You are using an older platform of JavaCV. You must try again with JavaCV 1.5.1. Maybe there is something that can be fixed.
