Hi,
sorry for the late reply, too much time spent for the MeeGo conference.

Usually when an EOS occurs the pipeline state goes to READY (if you want to
bring it to NULL, you need to do it i.e. in your bus callback).

This is pretty strange, most likely due to the HW-specific elements you're
using (either dmaidec_h264 or omapsink). I suggest you to check your dmesg
output and your BSP manual to know what's happening and how to restore
functionality without a reboot.
Are you sure even hw independent pipelines of the like of:
gst-launch audiotestsrc ! fakesink -v
are not working?
