ffmpeg를 사용하는 Android 앱에서 작업하고 있습니다. 나는 ffmpeg를 크로스 컴파일했고 대부분의 장치에서 잘 작동한다. 하지만 일부 삼성 장치에서 libffmpeg-neon.so 파일을로드하는 중일 때 치명적인 신호 11이 발생합니다. 내가 디버그 기호 (--disable-stripping --enable-debug=3 및 cflags += -gstabs+)과는 FFmpeg을 다시 컴파일 한 및 스택 추적 한android : libffmpeg-neon library로드 중 : 치명적인 신호 11

문제는 내가 그래서 난 할 수없는 그림는 FFmpeg 소스에서 check_for_sync 또는 kernelhelper을 찾을 수 있다는 것입니다 뭐가 잘못 됐는지. 이견있는 사람?
추신. 난 readelf -Ws libffmpeg-neon.so | grep 8b076c 시도하고 아무것도.
