Schedule the replacement of a video without changing the default layout

I would like to know if it is possible to program the replacement of a single media in a given playlist and apply a start, an end and a possible recurrence.
I saw that it is possible to do it with the layout of a display but not directly on the media of a playlist.
Can you inform me on this point?

Thank you for your post. It’s not clear from your message if you want to change the Media in a Layout using your CMS or externally using the API or other method. If you would like to use your CMS to make a change, then simply log in and open your Layout in the Designer. You can then make any changes to the media in that Layout, for example replacing the video with an alternative one. Once you have made these changes, they will be communicated to your Display that has the Layout scheduled and the required media will be downloaded.

If you are looking to set up a solution external to your CMS, you may be able to use the Xibo API. I have included links to the API options and documentation for more information. If you have any questions about the API functionality, please post in the Dev channel of the Xibo forum for support.

In CMS version 2, you have Expiry Tools for media items in your Layouts, I wondered if this provides the functionality you are looking for? A link to the Tools documentation for CMS 2.0 is below, which contains a section on the Expiry dates option:
