# Camera stream configuration
Source: [https://docs.qualcomm.com/doc/80-70022-50/topic/camera-stream-configuration.html](https://docs.qualcomm.com/doc/80-70022-50/topic/camera-stream-configuration.html)
The **gst-add-streams-as-bundle-example** application allows you to activate and
configure camera streams as a bundle instead of configuring each stream one at a time thus
reducing the delay in configuring new streams.
The following figure shows the pipeline, which takes the configuration parameters such as
width and height, processes to either display on a screen, or encodes and saves to a
file. For more information about the plugins used in the pipeline, see [Pipeline flow](https://docs.qualcomm.com/doc/80-70022-50/topic/camera-stream-configuration.html#camera-stream-configuration__section_vt5_b1b_pbc).

## Run the application
1. Ensure that you complete the [Prerequisites](https://docs.qualcomm.com/doc/80-70022-50/topic/mm_sample_apps_prerequisites.html).
2. In the terminal of the target device, use the following command to run the
application:
gst-add-streams-as-bundle-example Copy to clipboard
3. Use the following commands to run the application for various use cases:
- Preview the stream:
gst-add-streams-as-bundle-example -o DisplayCopy to clipboard
- Encode the stream and save it to a
file:
gst-add-streams-as-bundle-example -o FileCopy to clipboard
The
encoded stream is saved at
/etc/media/video\_%d.mp4.
4. To stop the use case, use CTRL +
C.
5. In the terminal of the target device, run the following command in the SSH shell
to display the available help
options:
gst-add-streams-as-bundle-example --helpCopy to clipboard
6. In the terminal of the host computer, run the following command to pull the
files from the target
device:
scp root@:/etc/media/Copy to clipboard
## Expected output
One stream is sent to display and the other stream is saved to a file.
