First of all, try to use the latest stable version. That is, 1.10.2 at
this point:
https://gstreamer.freedesktop.org/data/pkg/android/1.10.2/

There is no ffdec_h264 in GStreamer 1.x, it is called avdec_h264
now. Please do proper error checking in your application, the above
should've put something into the GError, like you can also see in
logcat.

And after that, setting the pipeline state to PLAYING or PAUSED
should've failed, and you probably also received an ERROR message.
