Howerver, when the NNStreamer line is disabled (which means the bottom queue is not linked to the upper tee), the FPS value measured by fpsdisplaysink is 30, same as that of input.\r\n\r\n#### How to reproduce ####\r\n- Clone https://github.com/wooksong/nnstreamer/tree/issue-546\r\n- Build\r\n- 1. For the nnline-enabled running, \r\n```\r\n./nnstreamer_example_filter_performance_profile -c /dev/video0\r\n```\r\n![image](https://user-images.githubusercontent.com/2772376/45674440-1a7a0f80-bb68-11e8-945a-9ba170cacfc3.png)\r\n\r\n- 2.
