在ndk9环境下编译ffmpeg

1.copy follow file to ffmpeg directory. build_android_dynamic.sh build_android_static.sh configure 2.make sure the script is executable by the command below chmod +x build_android_dynamic.sh chmod +x build_android_static.sh chmod +x configure 3.compile dynamic lib or static lib compile dynamic lib: ./build_android_dynamic.sh compile static lib: ./build_android_static.sh lib position: ./android/arm ---------------------------------- configure file from follow update ---------------------------------- Open configure file with a text editor, and locate the following lines. ------------------------------------------------------------------------ SLIBNAME_WITH_MAJOR='$(SLIBNAME).$(LIBMAJOR)' LIB_INSTALL_EXTRA_CMD='$$(RANLIB) "$(LIBDIR)/$(LIBNAME)"' SLIB_INSTALL_NAME='$(SLIBNAME_WITH_VERSION)' SLIB_INSTALL_LINKS='$(SLIBNAME_WITH_MAJOR) $(SLIBNAME)' This cause ffmpeg shared libraries to be compiled to libavcodec.so.<version> (e.g. libavcodec.so.55), which is not compatible with Android build system. Therefore we��ll need to replace the above lines with the following lines. ------------------------------------------------------------------------ SLIBNAME_WITH_MAJOR='$(SLIBPREF)$(FULLNAME)-$(LIBMAJOR)$(SLIBSUF)' LIB_INSTALL_EXTRA_CMD='$$(RANLIB) "$(LIBDIR)/$(LIBNAME)"' SLIB_INSTALL_NAME='$(SLIBNAME_WITH_MAJOR)' SLIB_INSTALL_LINKS='$(SLIBNAME)'
