SIGILL 신호가 내 Android 앱에 전송되었습니다.

Question

내 애플리케이션에서 스트리밍 비디오 (RTSP 프로토콜을 통해)를 재생할 수 있기를 원합니다. 열린 RTSP 스트림을 찾았습니다 : rtsp://red7blue.de/Primetime 그리고 재생하려고했습니다. 하지만 비디오를 재생하려고 할 때 SIGILL 신호로 내 응용 프로그램이 종료되었습니다. 나는 libffmpeg.so를 사용하고 있으며, SIGILL 시그널의 원인은이 라이브러리의 코드에있다. 내가 로그에 뭐가에서 봐 :

내가 SIGILL 신호의 원인 중 하나를 추측으로

특권 명령을 수행 할 수있는 시도 할 수있다. RTSP는 네트워크 프로토콜입니다. ffmpeg.so가 네트워크를 사용하여 미디어 스트림에 액세스하려고합니다. 어쩌면 몇 가지 특수 권한을 지정해야합니까? 내 앱에서 유일한 명시 적 권한이 있습니다. android.permission.INTERNET 다른 것을 지정해야합니까?

Answer 1

arm-eabi-objdump를 사용하면 libplayer-4.so 및 libffmpeg.so를 디스 어셈블 할 수 있습니다. 주소를 확인하려면 7d08, 4a2b는 libplayer-4.so, 2c6fe0은 libffmpeg에 있습니다.

주소를 찾은 후 레이블을 찾으십시오. 함수 이름입니다.

Answer 2

같은 오류가 발생했습니다. 곧 armv-7 플랫폼 용 프로그램을 컴파일하고 arm v5에서 runnig를 시도했기 때문에 문제가 있음을 깨달았습니다. Application.mk에서 다음과 같은 부분을 언급 할 수 있습니다. #APP_ABI : = armeabi-v7a
