Building a shared library from static libraries for ffmpeg 2.5.2
7 janvier 2015, par abijinxI am currently building a shared library for ffmpeg as myffmpeg.so using ffmpeg 0.8.6. I am achieving by combining static libs of individual modules of ffmpeg, along with a few additional static libraries. The main makefile used is as follows :
LOCAL_PATH := $(call my-dir)
include $(LOCAL_PATH)/Android_Files.mk
include $(CLEAR_VARS)
LOCAL_MODULE:= libavcodec
LOCAL_SRC_FILES:= $(MY_AVCODEC_FILES)
include $(LOCAL_PATH)/Android_Common.mk
include $(BUILD_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE:= libavfilter
LOCAL_SRC_FILES:= $(MY_AVFILTER_FILES)
include $(LOCAL_PATH)/Android_Common.mk
include $(BUILD_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE:= libavformat
LOCAL_SRC_FILES:= $(MY_AVFORMAT_FILES)
include $(LOCAL_PATH)/Android_Common.mk
include $(BUILD_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE:= libavutil
LOCAL_SRC_FILES:= $(MY_AVUTIL_FILES)
include $(LOCAL_PATH)/Android_Common.mk
include $(BUILD_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE:= libswscale
LOCAL_SRC_FILES:= $(MY_SWSCALE_FILES)
include $(LOCAL_PATH)/Android_Common.mk
include $(BUILD_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE:= ffmpeg_myc
LOCAL_SRC_FILES:= ffmpeg.c cmdutils.c
include $(LOCAL_PATH)/Android_Common.mk
include $(BUILD_STATIC_LIBRARY)
include $(CLEAR_VARS)
LOCAL_MODULE := myffmpeg
LOCAL_WHOLE_STATIC_LIBRARIES := libavcodec libavfilter libavformat libavutil libswscale ffmpeg_c
LOCAL_LDFLAGS += -lz -lm -llog
ifeq ($(FF_ENABLE_AMR),yes)
LOCAL_WHOLE_STATIC_LIBRARIES += opencore-amrnb opencore-amrwb
endif
ifeq ($(FF_ENABLE_AAC),yes)
LOCAL_WHOLE_STATIC_LIBRARIES += vo-aacenc
endif
include $(BUILD_SHARED_LIBRARY)The above makefile uses only few selected source files to get the individual static libs as mentioned in the FF_SOURCE_FILES parameter.Then combines all of those with the additional libs to create a shared library myffmpeg.so.
Now I am trying to get a similar output with ffmpeg 2.5.2 for 64-bit arm architecture. This time I have built the latest ffmpeg using the following configure script and generated the static libraries of different ffmpeg modules like libavcodec.a, libavfilter.a, etc
#!/bin/bash
ABI=aarch64-linux-android
NDK=
SYSROOT=$NDK/platforms/android-21/arch-arm64/
TOOLCHAIN=$NDK/toolchains/aarch64-linux-android-4.9/prebuilt/linux-x86_64

PREFIX=$(pwd)/android/$CPU

--enable-libopencore-amrwb \
--enable-libvo-aacenc \
$ADDITIONAL_CONFIGURE_FLAG
make clean
make
make installNow I am trying to combine the generated static libraries i.e
-
libavcodec.a
libavfilter.a
libavformat.a
libavutil.a
libswresample.a
libswscale.a
with -
ffmpeg_myc opencore-amrnb opencore-amrwb
and generate a myffmpeg.so shared library by giving ndk-build.
I tried to paste the generated ffmpeg static libraries from ffmpeg/android folder to obj/local/arm64-v8a (path where are all the static libs were previously created in 0.8.6 according the makefile). I also made changes to the makefile thinking that it will use the already generated ffmpeg libraries. But I found that the size of the generated shared library was too low and that it has not included the generated ffmpeg libs.
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := myffmpeg
LOCAL_WHOLE_STATIC_LIBRARIES := libavcodec libavfilter libavformat libavutil libswscale ffmpeg_c
LOCAL_LDFLAGS += -lz -lm -llog
ifeq ($(FF_ENABLE_AMR),yes)
LOCAL_WHOLE_STATIC_LIBRARIES += opencore-amrnb opencore-amrwb
endif
ifeq ($(FF_ENABLE_AAC),yes)
LOCAL_WHOLE_STATIC_LIBRARIES += vo-aacenc
endif
include $(BUILD_SHARED_LIBRARY)I would like to know whether I am going in a right way and have to do some minor changes. Or if I should start with an entirely different approach to achieve this. Any suggestions would be helpful.
Thanks in advance
