Hi All,
I am working on aac_codec integration to Android platform.
Below are the steps I have followed to create the shared lib
libomx_my_sharedlibrary.so
1) I am creating the codec library and component as static named
lib_aac_dec_my, lib_aac_comp_my.
2) Using this two static lib I am creating the aac shared library
named libomx_aacdec_my_sharedlib which I am linking to the omx core
lib.
3) Makefile I have used for creating omx core lib is below
LOCAL_SRC_FILES := \
src/omx_my_core.c \
LOCAL_MODULE := libomx_core_my
LOCAL_PRELINK_MODULE := false
LOCAL_SHARED_LIBRARIES := \
libomx_aacdec_my_sharedlibrary \
libdl
LOCAL_C_INCLUDES := \
.....................................
--------------------------
include $(BUILD_SHARED_LIBRARY)
4) pv-omx-interface lib is created according to the template provided.
Below is the sample of Android.mk I have used for creating the
interface lib.
LOCAL_SRC_FILES := \
src/my_pv_omx_interface.cpp
LOCAL_MODULE := libpv_omx_my_interface
Other stuff......
include $(BUILD_STATIC_LIBRARY)
5) The final shared library libomx_my_sharedlib.so is created using
the follwing
LOCAL_WHOLE_STATIC_LIBRARIES := \
libpv_omx_my_interface
LOCAL_MODULE := libomx_my_sharedlibrary
LOCAL_PRELINK_MODULE := false
LOCAL_SHARED_LIBRARIES += libomx_core_my libopencore_common
include $(BUILD_SHARED_LIBRARY)
Other stuff....
6) The final shared lib is mentioned in the my.cfg file with the
OMX_INTERFACE_ID.
But while testing I have figured out that it is reading the library
from the my.cfg file ,but it is not able to open that library , in
Oscl_shared_library.cpp loadlibrary() dlopen() fails to open my shared
lib.
The following logs I get...
E/ ( 777): Oscl_shared_library.cpp LoadLib IN
E/ ( 777): Loading library=libomx_my_sharedlibrary.so
E/ ( 777): Oscl_shared_library.cpp loadlibrary IN
E/ ( 777): Opening Library
E/ ( 777): Opening Library Fail Cannot find library
E/ ( 777): Oscl_shared_library.cpp loadlibrary OUT
E/ ( 777): Oscl_shared_library.cpp LoadLib Fail OUT
Can anyone help me in finding out where exactly I am going wrong?
Thanks & Regards,
Anupama
