# Video composition use cases

Source: [https://docs.qualcomm.com/doc/80-70015-50/topic/video-composition.html](https://docs.qualcomm.com/doc/80-70015-50/topic/video-composition.html)

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

Before you run the use cases, ensure that you complete the preconditions mentioned in
                [Multimedia use cases](https://docs.qualcomm.com/doc/80-70015-50/topic/multimedia-use-cases.html).

- **[16 480p offline stream side-by-side composition](https://docs.qualcomm.com/doc/80-70015-50/topic/16-480p-offline-stream-side-by-side-composition.html)**  

The pipeline shows the use case for reading 16 480p video streams from file sources         and composing them side by side. These streams are then displayed as a single frame on a         local display device.
- **[1080p + 1080p offline picture-in-picture composition](https://docs.qualcomm.com/doc/80-70015-50/topic/1080p-1080p-offline-picture-in-picture-composition.html)**  

This pipeline shows the composition of two 1080p streams to get a picture-in-picture         display. The two 1080p streams are read from two file sources.
- **[1080p live camera and 1080p offline picture-in-picture composition](https://docs.qualcomm.com/doc/80-70015-50/topic/1080p-live-camera-and-1080p-offline-picture-in-picture-composition.html)**  

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