* This is an example pipeline to recognize difference between ROI and non-ROI.

* 2. Encode and decode the raw data with 2 pipelines at same time.
* 2.1. Insert GstVideoRegionOfInterestMeta to the 2nd pipeline buffers to enable ROI.
* 3. Mix both streams in videomixer.
* 5. Output the result in one window.
*
* Note that the higher definition of original raw data, the easier we
* recognize. So you can replace videotestsrc with your
* high-definition camera or other src elements.
