To stop a video at the first frame after it is open

Hi,

I d like to do a patch that screens on pause the first frame of a video after I open it by clicking on "read" object. But the video starts automatically when I click on "read". I tried to use a delay of 50 ms linked to the "stop" button, but it stops at the second or third frame of the video. If I link the "stop" button to the "read", the patch ignore the "stop".

Thanks for your help if you have an idea!

Frederic.
