# Live snapshot
The **gst-snapshot-stream-example** application allows you to generate two streams: a preview stream for live display and a snapshot stream that captures images and saves them as JPEG files.
Note
This sample application isn’t supported on Dragonwing IQ-8275 and Dragonwing IQ-9075.
For the snapshot stream, you can determine the number of snapshots.
The following figure shows the pipeline, which allows for simultaneous live preview and snapshot capture from the same video source.
For more information, see [Pipeline flow](https://docs.qualcomm.com/doc/80-80021-50/topic/gst-snapshot-stream-example.html#section-lny-sly-nbc).

## Run the application
1. Ensure that you complete the [Prerequisites](https://docs.qualcomm.com/doc/80-80021-50/topic/mm_sample_apps_prerequisites.html).
2. In the terminal of the target device, use the following command to run the use case. Specify the application with parameters, such as camera width, height, and the maximum snapshot count for dumping JPEG files.
gst-snapshot-stream-example -W 1280 -H 720 -w 3840 -h 2160 -c 5

3. To stop the use case, use **CTRL + C**.
4. In the terminal of the target device, run the following command in the SSH shell to display the available help options:
gst-snapshot-stream-example --help
Copy to clipboard
## Expected output
The application generates an output for preview on the display and dumps the JPEG files in the respective location on the device.
After the use case stops, the snapshot output files are available at the `/etc/media/` path.
## Pipeline flow
The following table lists the plugins used in the live snapshot pipeline:
| **Plugin** | **Description** |
| --- | --- |
| [qtiqmmfsrc](https://docs.qualcomm.com/doc/80-80021-50/topic/qtiqmmfsrc.html) | Captures the video stream and feeds it into the capsfilter. |
| Capsfilter | Branches the source into two separate pipelines. In one pipeline, the constraints on the raw video data are enforced, and then the video data is sent to [Waylandsink](https://docs.qualcomm.com/doc/80-80021-50/topic/waylandsink.html) for live preview. |
| Capsfilter |
In the other pipeline, the frames are written to multiple files using multi filesink.
The snapshots or frames from the video stream are saved to a disk.
