Shared Library not found error on android LogCat

问题:

I'm trying to develop android app which can stream images from the camera to a server. So I've found a project that stream to the browser and you can find here: http://code.google.com/p/ipcamera-for-android/

I'm trying to run this code, but I get an error:

06-28 12:43:47.030: E/AndroidRuntime(31749): java.lang.UnsatisfiedLinkError: Cannot load library: link_image[1963]: 1567 could not load needed library 'libffmpeg.so' for 'libipcamera.so' (load_library[1105]: Library 'libffmpeg.so' not found)

The part of the code where I load them:

public static void LoadLibraries() {
        System.loadLibrary("teaonly");      
        System.loadLibrary("ipcamera");     
    }

Here is the compiling native code image: (no errors)

and here is the Android.mk file:

include $(LOCAL_PATH)/build.mk

include $(BUILD_SHARED_LIBRARY)

My questions are:

• Do you guys know how to fix this error?
• Is that possible to get an response (like the video processed) from the server? It would be like a p2p app.

回答1:

try to use

LOCAL_SHARED_LIBRARIES += libffmpeg-prebuild 

instead of

LOCAL_SHARED_LIBRARIES := libffmpeg-prebuild libteaonly

hope this will solve ur problem....
