Fix refcount issue with input buffers

It seems there is refcount error in stream_data_new and mpegtsmux is segfault
with both schroenc and x264enc with the following pipeline:

gst-launch-1.0 videotestsrc ! x264enc ! mpegtsmux ! fakesink

(gst-launch-1.0:6206): GStreamer-CRITICAL **: gst_mini_object_unref: assertion
`mini_object->refcount > 0' failed

Program received signal SIGTRAP, Trace/breakpoint trap.
