FFMpegBuildScript

A ffmpeg build script for Android

If you want build for x86, you should make change like this:

diff --git a/libavcodec/x86/mpegvideoenc.c b/libavcodec/x86/mpegvideoenc.c
index b410511..5144f42 100644

##You also have to modify config.h like this when build x86 dynamic library:

#define HAVE_LOG2 0
#define HAVE_LOG2F 0
#define HAVE_LOG10F 0
