how to remove the window that opens when you start a video

[Emmanuel5CFD]

Hello, 
I created a button on which the action is to open a video. The button, action and opening of the video are good. On the other hand, there is a pop-up window ("launch the file" ...) that opens above the PDF with the obligation to click yes or no. I don't want this window. How to do?
Thank you

Hi,

This is a security method which makes sure that the user understands that a separate application will be launched ( vlc ) in this case.

I believe you can make the document trusted which may stop this dialog from showing, more information is here

This seems very interesting and very detailed. I'm going to read this seriously, there will surely be the solution I'm looking for.
Many thanks for this BarlaeDC

Il faut remplacer "Invite" par "Toujours". Un dessin vaut mieux qu'un long discours :

bonjour JR,
j'avais déjà essayé cette option qui semble être prévue pour ma situation, hélas ça ne fonctionne pas.
Pour info je suis conscient que ce serait une préférence à instaurer sur chaque support, et en l'occurence ce n'est pas un problème.
merci pour le bo croquis

Just to say that this is a user decision. So on a different computer and a for a different user, you will get the question again.
