The GStreamer pipelines for video composition show the use cases for reading video
        streams from the source, and composing and displaying them either side-by-side or
        picture-in-picture on a display device.

Before you begin executing the use cases, ensure that you complete the preconditions
            mentioned in Multimedia use cases.

- **16 480p offline stream side-by-side composition**  

The pipeline shows the use case for reading 16 480p video streams from file sources         and composing them side-by-side, and then displaying them as a single frame on a local         display device.
- **1080p + 1080p offline picture-in-picture composition**  

This pipeline shows composition of two 1080p streams to achieve picture-in-picture         display. The two 1080p streams are read from two file sources.
- **1080p live camera and 1080p offline picture-in-picture composition**  

The pipeline shows the composition of two 1080p streams to achieve picture-in-picture         display. The first 1080p stream is read from a file source. The second stream is collected         from a camera.
