Crash on Android 6 and newer (7) with JavaCPP 1.2.0

[N0un]

Hi !
I use javaCPP FFMPEG preset for my app and it works fine for Android 5 or older devices. I took the precompiled armeabi-v7a and x86 libraries (1.2 with FFMPEG 3.0.2) and it crashes at the call of "avcodec_register_all();" (the first call of this lib) for each device configuration based on Android 6 and 7 (arm, arm64, x86). So impossible to use JavaCPP (and FFMPEG preset but I think the error comes from JavaCPP) with Android 6 or newer. Here is an example of log with an emulator running on Android 6 with an x86 system based :

The error is similar for all configuration but on Android 7 it's not a sigsegv code 1 but code 2 (at least on arm64) but with the same trace. Any idea? Thanks !

Ok I solve this using the latest JavaCPP version : 1.2.3. Thank you a lot for the work, I close the issue.

I find solution here :
