[fernando-closs-clansoft]

Description Android - Crash on device - AndroidJavaException: java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "__register_atfork" referenced by "libmobileffmpeg_abidetect.so"

Seems to be related to com.arthenica.mobileffmpeg.Config.ignoreSignal(Signal.SIGXCPU)

Expected behavior No error

Current behavior app crashes when com.arthenica.mobileffmpeg.Config.ignoreSignal(Signal.SIGXCPU); is called

E/Unity: AndroidJavaException: java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "register_atfork" referenced by "libmobileffmpeg_abidetect.so"... java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "register_atfork" referenced by "libmobileffmpeg_abidetect.so"... at java.lang.Runtime.loadLibrary(Runtime.java:372) at java.lang.System.loadLibrary(System.java:988) at com.arthenica.mobileffmpeg.AbiDetect.(AbiDetect.java:33) at com.arthenica.mobileffmpeg.AbiDetect.getNativeAbi(Native Method) at com.arthenica.mobileffmpeg.Config.(Config.java:131) at com.clansoft.tacticalpad.TacticalPadAndroidActivity.startFFmpegVideo(TacticalPadAndroidActivity.java:1171)

Line 1171 of my java is com.arthenica.mobileffmpeg.Config.ignoreSignal(Signal.SIGXCPU);

Environment

• Android 5.1.1 - Works normally on Android 9
• Arm7
• mobile-ffmpeg 4.4
• From release aar (on github)

Other After a little search, it looks like __register_atfork is available from API >= 24 (the aar minSDK is correctly set to 24, only the documentation here on github says 16)

You need one of the LTS builds to run mobile-ffmpeg on Android 5 (or whatever version with API level from 16 upto 23).

Ok. Thanks. I will try that as soon as I can and check the ignoreSignal on LTS for <= API 23. Thanks.
