# Video overlay use cases

Source: [https://docs.qualcomm.com/doc/80-70014-50/topic/overlay-use-cases.html](https://docs.qualcomm.com/doc/80-70014-50/topic/overlay-use-cases.html)

The pipelines show use cases for overlaying on the video stream at the coordinates
        mentioned in *dest-rect* property in the *overlay-mask* property of the [qtioverlay](https://docs.qualcomm.com/doc/80-70014-50/topic/qtioverlay.html) plugin.

Before you begin executing the use cases, ensure that you complete the preconditions
            mentioned in [Multimedia use cases](https://docs.qualcomm.com/doc/80-70014-50/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/80-70014-50/topic/qtioverlay.html).

- **[User text overlay](https://docs.qualcomm.com/doc/80-70014-50/topic/user-text-overlay.html)**  

This pipeline overlays text onto the video stream.
- **[Date and time overlay](https://docs.qualcomm.com/doc/80-70014-50/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/80-70014-50/topic/static-image-overlay.html)**  

This pipeline shows how to overlay the static image onto the video         stream.
- **[Bounding box overlay](https://docs.qualcomm.com/doc/80-70014-50/topic/bounding-box-overlay.html)**  

This pipeline shows how to overlay the bounding box with label onto the video         stream.
- **[Inverse privacy mask](https://docs.qualcomm.com/doc/80-70014-50/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/80-70014-50/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/80-70014-50/topic/polygon-privacy-mask.html)**  

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