It’s better if you write the build script yourself, which is not easy for most developers. We don’t think this is the best solution for building speex libraries. To build an x86 library, you must add “-DFLOATING_POINT=1 -D_USE_SSE -D_USE_SSE2”. Please read for more detail ( This blog is in Chinese, but can be easily read using Google Translator). Most developers use the NDK to build speex. Speex is a free speech codec, widely used in VoIP and sound recorder applications. #endif /* HAVE_SSE2_INLINE */ Speex Compiling S- >apply_window_float = apply_window_mp3 Change mpegaudiodsp.c and delete these lines of code: Note! A compiling error occurs on old FFmpeg versions when yasm is enabled. You must install yasm on your Linux system. Link these libraries to your project as a prelink static library to get a FFmpeg dynamic library.įor the best performance, use “enable-asm” and “enable-yasm”. OPTIMIZE_CFLAGS= " -march=atom -ffast-math -msse3 -mfpmath=sse"Īfter running this script, you will get libavcode.a, libavformat.a, libavutil.a, libswresample.a, and libswscale.a files. disable-ffplay -disable-avfilter -disable-avdevice -disable-ffprobe extra-ldflags= " -Wl,-rpath-link=$PLATFORM/usr/lib -L$PLATFORM/usr/lib -nostdlib -lc -lm" extra-cflags= " -O3 -fpic -DANDROID -DHAVE_SYS_UIO_H=1 -fasm -Wno-psabi -fno-short-enums -fno-strict-aliasing -finline-limit=300 $OPTIMIZE_CFLAGS " cross-prefix=$PREBUILT/bin/i686-android-linux.
