DJI MSDK (version 5.7.1) compatibility with OpenCV. ERROR No implementation found for int djimrtc.natives.MRTCController.initNativeMRTCCore(java.lang.String)
Completed
Error occur when implementing opencv, there are 2 files found with same path
'lib/arm64-v8a/libc++_shared.so'
'lib/armeabi-v7a/libc++_shared.so'
and using in gradle
packagingOptions {
pickFirst 'lib/arm64-v8a/libc++_shared.so'
pickFirst 'lib/armeabi-v7a/libc++_shared.so'
pickFirst 'lib/armeabi-v7a/libc++_shared.so'
}
leading app crashing after 5-7 seconds (probably because of cant reach compatible jetified-dji-sdk-v5-aircraft-5.7.1\jni\arm64-v8a\libc++_shared.so , because it took opencv .so files).

Any suggestion how to solve this problem? as i understand both are necessary. How i can find compatibility?

I'm using OpenCV 4.8.0 . I tried with msdk 5.5.0 as you said, still same error.

Can you show your app build.gradle file? -
Did you do something with RTMP functionality provided by dji sdk, because that's when the crash happens!
for example
liveStreamManager.startStream(object : CommonCallbacks.CompletionCallback {
override fun onSuccess() {
Log.d(TAG, "startStream(): RTMP stream started.")
Log.d(TAG, liveStreamManager.isStreaming.toString())
}
override fun onFailure(error: IDJIError) {
Log.e(TAG, "startStream(): ${error.errorCode()} ${error.description()}")
}
})
