# Video wall

The **gst-concurrent-videoplay-composition** application supports concurrent video playback for MP4 AVC (H.264) videos and performs composition on a video wall display.

In the concurrent video playback and composition pipeline, four decode and composition pipelines run concurrently. For more information about the plugins used in this pipeline, see [Pipeline flow](https://docs.qualcomm.com/doc/80-80021-50/topic/video-wall-using-python.html#section-s22-qsf-4bc).

## Run the application

| Use case | Description |
| --- | --- |
| Video conferencing | <ul class="simple"><br><li><p>Simultaneously decodes the video streams of several participants.</p></li><br><li><p>Useful in a multi-party video conference scenario where the application manages several video streams.</p></li><br></ul> |
| Surveillance systems | Concurrently decodes video feeds from two separate cameras. |
| Digital signage | Allows simultaneous changes or updates to centrally managed information that’s electronically displayed across several locations. |

To run the use cases, do the following:

1. Ensure that you complete the [Prerequisites](https://docs.qualcomm.com/doc/80-80021-50/topic/mm_sample_apps_prerequisites.html).
2. Input at least one `MP4 AVC (H.264)` video file on the target device.
3. In the terminal of the target device, use the following command to run the use case:

gst-concurrent-videoplay-composition -c <number of streams> -i <input-file-1>.mp4 -i <input-file-2>.mp4
        Copy to clipboard

| Command-line parameter | Description |
| --- | --- |
| `-c` | <ul class="simple"><br><li><p>Number of streams to decode for composition.</p></li><br><li><p>Supported values are 2, 4, 8, and 16.</p></li><br></ul> |
| `-i` | Specifies the absolute path to the input video file. |

For example, use the following commands to run the concurrent playback use cases:
    
    -   Concurrent playback of two sessions:
    
        ``` {#codeblock_mh1_vl3_y1c}
        gst-concurrent-videoplay-composition -c 2 -i <input-file-1>.mp4 -i <input-file-2>.mp4
        ```
    
        If one video is provided as input, the same file is played concurrently.
    
    -   Concurrent playback of four sessions:
    
        ``` {#codeblock_wfn_wl3_y1c}
        gst-concurrent-videoplay-composition -c 4 -i <input-file-1>.mp4 -i <input-file-2>.mp4 -i <input-file-3>.mp4 -i <input-file-4>.mp4
        ```
    Copy to clipboard

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-concurrent-videoplay-composition --help
        Copy to clipboard

## Expected output

The individual composed streams are tiled together to display as a unified stream.
