Problem Definition

Multimedia Macro allows you to autoplay a video, but not play it on a loop

Suggested Solution

Provide an option to loop media using the multimedia macro

Workaround

1. Enable HTML Macro
2. Link to video using HTML:

   <video controls loop>
   <source src="/download/attachments/000000/name-of-video.mp4" type="video/mp4">
   </video>

   For loop AND autoplay:

   <video controls autoplay loop>
   <source src="/download/attachments/000000/name-of-video.mp4" type="video/mp4">
   </video>

Note:

if you want to link to a video already attached to a Confluence page, you can attach it using Multimedia Macro, then inspect the element using your browser while viewing the page, and you will be able to obtain the URL of the video this way.
