GStreamer 1.5.2 successfully work on OSX but fail on Android?

[A PU]

Hi,

I try to build a cross-platform application using QT 5.5.1,

I want to use GStreamer 1.5.2 to stream a camera view to the application
through RTSP protocol.

I downloaded the binary packages for different platform from the indicated
websites

https://gstreamer.freedesktop.org/data/pkg/osx/1.5.2/

https://gstreamer.freedesktop.org/data/pkg/android/1.5.2/

The problem is, with the same code(streaming pipeline), the camera view can
be seen on OSX,

however, as I deploy the application to an Android device, the streaming
fail, and no error is shown.

If only there is any message or warning showing up will be helpful for me
to debug, sadly during the building process, deploying process and runtime
process every thing goes smoothly, expect no video is streaming on the
application at last.

I understand this could be a rouge problem and contains many possible
issues, I have been struggled for a week, thinking about any possible root
cause.

My suspicion tells me something's wrong within the libraries, maybe I
forgot to include a specific one, but there should be error when I compile?

I am hoping to get some advices, thank you.
