Graphics disappear when palying a video file


Someone can help ?

I am trying to simulate capturing from video file.

When I am playing the video using Qplayer (From Qt library)

Main screen images (in background) disappeared.



I notice that when using the viewPort method it's the only reason from that problem.

I tried to use the examples of the QMedia player from Qt documents with no success

(I couldn't set the player into my GUI)

I used the OpenCV project in order to create my capture player using Stephen Nneji code

from the link: [ ... eo-using..](

Hope I could help for some last souls :slight_smile:
