Cannot locate symbol "av_q2intfloat" referenced by "libjniavutil.so"

[beta]

I created an instance of FFmpegFrameGrabber like

FFmpegFrameGrabber grabber = new FFmpegFrameGrabber("...");

and an error occurred:

08-20 02:32:55.621  21569-21569/org.lab413.visualnav E/art: dlopen("/data/app/org.lab413.visualnav-1/lib/x86/libjniavutil.so", RTLD_LAZY) failed: dlopen failed: cannot locate symbol "av_q2intfloat" referenced by "libjniavutil.so"...

I've installed JavaCV correctly following the steps from Manual Installation. I'm using JavaCV with

• Gradle 1.2.3
• Android SDK version 22
• Android build tools 22.0.1
• Android Studio 1.3.1
• Genymotion with Android 5.1 (x86)

[beta]

I tried with a real ARM device running Android 5.0.1 instead of an emulator, and the error didn't occur. But here comes another error:

java.lang.UnsatisfiedLinkError: org.bytedeco.javacpp.avutil

I found this issue and solved the problem, but don't know the reason.

It's an issue with Android Studio's build system...
