Source: [https://docs.qualcomm.com/doc/80-70022-50/topic/gst-multi-stream-example.html](https://docs.qualcomm.com/doc/80-70022-50/topic/gst-multi-stream-example.html)
The **gst-multi-stream-example** application allows you to access several streams
from a single camera and either display them simultaneously on a screen or save them in MP4
format.
For example, you can use this application for a camera security system where the video is
captured from a camera. This video can be simultaneously streamed over a network,
displayed on a monitor, and archived for future review.
The figure shows the pipeline, which is run with flags to specify width, height, stream
count, and output file.
For more information, see Pipeline flow.
