Odoo's default configuration supports only a limited set of video hosting platforms such as YouTube, Vimeo, Dailymotion, and Youku. However, you can customize Odoo to accept a BunnyCDN video URL or any other custom video hosting platform. Here's myl approach you can take to achieve this:

1- In Odoo, you'll need to modify the code to allow for custom video hosting URLs. This may involve making changes to the existing codebase or creating a new module to handle the custom video URLs.

2- Odoo likely uses a validation mechanism to ensure that the provided URL is from a supported video hosting platform. You'll need to identify this validation code and modify it to accept BunnyCDN URLs or disable the validation altogether.

3- Locate the code responsible for validating video URLs in Odoo. This code might be found in a specific module related to video handling. You'll need to modify the validation logic to recognize BunnyCDN URLs as valid.

4- Once you've adjusted the validation logic, you should update the product video upload form in Odoo to include an additional field for custom video URLs or modify the existing field to accept any valid URL.

5- After implementing the changes, thoroughly test the functionality to ensure that it accepts BunnyCDN video URLs as expected. Once you're confident in the changes, deploy them to your production environment.
