Next step would be to look at the latency of the decoder.

  GST_TRACERS=latency\(flags=element\) GST_DEBUG=GST_TRACER:8 ./app 2> gst.log
  gst-stats gst.log

That should give us per element latency, we need to look at what is the latency
of nvh264dec here, and compare against avdec_h264. Another possibility is that
there is a timestamp issue.
