# Video overlay use cases

Source: [https://docs.qualcomm.com/doc/80-70015-50/topic/overlay-use-cases.html](https://docs.qualcomm.com/doc/80-70015-50/topic/overlay-use-cases.html)

The pipelines show the use cases for video overlay. These use cases use the
            *dest-rect* property coordinates from the *overlay-mask* property of the [qtioverlay](https://docs.qualcomm.com/doc/80-70015-50/topic/qtioverlay.html) plugin.

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).

Note: The commands in the following use cases use the 720p resolution.
            To change the resolution, update the respective *dest-rect* property coordinates in
            the command for that resolution. For more information, see [qtioverlay](https://docs.qualcomm.com/doc/80-70015-50/topic/qtioverlay.html).

- **[User text overlay](https://docs.qualcomm.com/doc/80-70015-50/topic/user-text-overlay.html)**  

This pipeline overlays text onto a video stream.
- **[Date and time overlay](https://docs.qualcomm.com/doc/80-70015-50/topic/date-and-time-overlay.html)**  

This pipeline shows the date (in MMDDYYYY) and time (in HHMMSS) to be overlaid onto         the video stream.
- **[Static image overlay](https://docs.qualcomm.com/doc/80-70015-50/topic/static-image-overlay.html)**  

This pipeline shows how to overlay a static image onto a video stream.
- **[Bounding box overlay](https://docs.qualcomm.com/doc/80-70015-50/topic/bounding-box-overlay.html)**  

This pipeline shows how to overlay a bounding box with a label onto the video         stream.
- **[Inverse privacy mask](https://docs.qualcomm.com/doc/80-70015-50/topic/inverse-privacy-mask.html)**  

This pipeline shows how to overlay the inverse privacy mask on the video         stream.
- **[Non-inverse privacy mask](https://docs.qualcomm.com/doc/80-70015-50/topic/non-inverse-privacy-mask.html)**  

This pipeline shows how to overlay the non-inverse privacy mask onto the video         stream.
- **[Polygon privacy mask](https://docs.qualcomm.com/doc/80-70015-50/topic/polygon-privacy-mask.html)**  

A polygon privacy mask enables you to create privacy zones on an image using a         polygonal shape. Using a polygon enables you to make the masking smoother and more         accurate.
