How to build armeabi ?

[devillee]

Hi , how to build armeabi for this ? I use your script built the ffmpeg all success,but failed in ndk build. Hope you can give me some advices.

The follow is the error :

I only run this on Ubuntu, not windows. The script is very likely to only run on Linux because I may hardcode the environment in it.

Thank you for your reply ! I build this in ubuntu , and I got some of .a file like libavcodec.a libavformat.a etc.. and I want to build this static lib with ndk in Windows and get one .so file in Android. this is my make file in android ndk:

LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_C_INCLUDES+= $(LOCAL_PATH)/include LOCAL_MODULE := libffmpegutil
LOCAL_SRC_FILES := com_android_concox_FFmpeg.c
LOCAL_LDLIBS := -llog -ljnigraphics -lz -landroid -lm -pthread LOCAL_LDLIBS +=$(LOCAL_PATH)/prebuilt/libx264.a LOCAL_LDLIBS +=$(LOCAL_PATH)/prebuilt/libfdk-aac.a LOCAL_LDFLAGS+=$(LOCAL_PATH)/prebuilt/libavformat.a LOCAL_LDFLAGS+=$(LOCAL_PATH)/prebuilt/libavfilter.a LOCAL_LDFLAGS+=$(LOCAL_PATH)/prebuilt/libavcodec.a LOCAL_LDFLAGS+=$(LOCAL_PATH)/prebuilt/libswscale.a LOCAL_LDFLAGS+=$(LOCAL_PATH)/prebuilt/libavutil.a LOCAL_LDFLAGS+=$(LOCAL_PATH)/prebuilt/libswresample.a LOCAL_LDFLAGS+=$(LOCAL_PATH)/prebuilt/libpostproc.a include $(BUILD_SHARED_LIBRARY)

after ndk-build , I really got a ffmpegutil.so file

But when i use aac encoder , I got en error -22 belows: codec id is AV_CODEC_ID_AAC int ret = avcodec_open2(c, codec, &opt)

seems like that ffmpeg or *.a file not link libfdk-aac correctly.

I have test for many ffmpeg with x264 aac script on Google, github and stackoverflow But not one of them is ok. Wish you can give me some advice about how to build a ffmpeg with x264 and aac NDK *.so file. Thank you very much!
