How to loop videos in Grafana dashboards?

To loop videos in Grafana dashboards, you can follow these steps:

1. Install the Panel Options plugin: First, install the Panel Options plugin in Grafana. This plugin allows you to add custom options to your panels.
2. Add a new HTML panel: Create a new panel in your Grafana dashboard and select the "HTML" panel type.
3. Configure the panel: In the "Content" section of the panel configuration, enter the HTML code to embed the video. For example, you can use the following code to embed a YouTube video:

1

<iframe width="560" height="315" src="https://www.youtube.com/embed/VIDEO_ID?autoplay=1&loop=1" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>

Replace VIDEO_ID with the ID of the desired YouTube video.

1. Add custom panel options: Scroll down to the "Panel Options" section of the panel configuration and add a new option to control the loop functionality. You can use the following JSON code:

1
2
3
4
5
6

{
  "name": "loop",
  "type": "boolean",
  "default": true,
  "label": "Loop Video"
}

1. Add JavaScript code: In the "JavaScript" section of the panel configuration, enter the following code:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14

// Get the loop option value
var loopEnabled = ctrl.panel.loop;

// Update the video URL to include the loop parameter
var iframe = document.getElementsByTagName('iframe')[0];
var url = iframe.src;

if (loopEnabled) {
  url = url.replace('&loop=0', '&loop=1');
} else {
  url = url.replace('&loop=1', '&loop=0');
}

iframe.src = url;

1. Save and test: Save the panel configuration and test the loop functionality by toggling the "Loop Video" option. The video should restart automatically when loop is enabled.

Note: Adjust the code and video embedding method based on the desired video platform and customization requirements.
