1. I used cerbero to build gst-plugins-base-1.0, and copy the dynamic .so to android to execute the command "./gst-inspect-1.0" .
But found error :
(gst-plugin-scanner:3238): GStreamer-WARNING **: Failed to load plugin '/data/android_arm/lib/libgstaudio-1.0.so': dlopen failed: could not load library "libgsttag-1.0.so" needed by "libgstaudio-1.0.so"; caused by could not load library "/home/qys/cerbero/dist/android_arm/lib/libz.so" needed by "libgsttag-1.0.so"; caused by library "/home/qys/cerbero/dist/android_arm/lib/libz.so" not found

2. I used ndk-depends command to see libgsttag-1.0.so, found that:
qys@his-Lenovo:~/cerbero/dist/android_arm/lib$ ndk-depends libgsttag-1.0.so
WARNING: Could not find library: /home/qys/cerbero/dist/android_arm/lib/libz.so

I don't known why libz.so is rpath?
Thank you very much.
