+## @param $2 test case ID
+## @param $3 set 1 if this is not critical (don't care if it's pass or fail)
+## @param $4 set 1 if this passes if launching the pipeline fails. (pass if timeout expires)
+## @param $5 set timeout for launching the pipeline in seconds (not the pipeline EOS). default = 10.
+## @return $pid The PID of the background gstreamer pipeline.
