# Enable video
This section outlines the prerequisites for video functionality, steps to render video, and methods to validate video playback and video recording.
The following workflow shows the sequence to get started with video functionality:
**Figure: Getting started workflow for video**
The workflow outlines the essential steps for initializing and starting a video-based system:
1. Prerequisites: Build and flash the required software, and establish an SSH connection to the target device.
2. Setup: Run the necessary commands from an SSH terminal and push a prerecorded video to the device.
3. Run: Run the required commands to validate video playback and recording.
## Prerequisites
- Build and flash the software. For information, see [Qualcomm Linux Build Guide](https://docs.qualcomm.com/bundle/publicresource/topics/80-80022-254/build_landing_page.html).
- Connect to the device using SSH. For information, see [Sign in using SSH](https://docs.qualcomm.com/bundle/publicresource/topics/80-80022-254/how_to.html#use-ssh).
## Set up video rendering
The setup procedure helps you render video content on the display and transfer it to the device.
To playback a video, transfer a prerecorded H.264 video to the device and run the following command from an SSH terminal:
>
>
> scp -r root@[DEVICE IP-ADDR]:/opt
> Copy to clipboard
>
>
> Note
>
>
> When prompted for a password, enter `oelinux123`.
## Validate playback and video recording
You can run a set of commands on the device terminal to validate the video playback and recording functionality.
**Validate video playback functionality**
1. To validate the video playback functionality, run the following command:
gst-launch-1.0 filesrc location=/opt/ ! qtdemux ! h264parse ! v4l2h264dec capture-io-mode=4 output-io-mode=4 ! video/x-raw,format=NV12 ! waylandsink fullscreen=true
Copy to clipboard
2. To stop validating the use case, select CTRL+C.
**Validate video recording functionality**
1. To validate the video recording functionality, run the following command:
gst-launch-1.0 videotestsrc num-buffers=1000 ! video/x-raw, format=NV12,width=1280,height=720,framerate=30/1,interlace-mode=progressive,colorimetry=bt601 ! queue ! v4l2h264enc capture-io-mode=4 output-io-mode=4 extra-controls="controls,video_bitrate=1000000,video_gop_size=29;" ! h264parse ! queue ! mp4mux ! filesink location=/opt/720p_AVC.mp4
Copy to clipboard
2. To stop validating the use case, select CTRL+C.
3. To pull the recorded content from the device, run the following Secure Copy Protocol (SCP) command:
scp -r root@[DEVICE IP-ADDR]:/opt/720p_AVC.mp4 user1@[HOST IP-ADDR]:/workspace
Copy to clipboard
4. Play the content on your host computer.
