[vlc-devel] MediaPlayer crash or deadlock (only) if mouse moves over video after libvlc_MediaPlayerEndReached

[Christian Gallant]

Hi,

a solution is to hide the playerwidget just befor deleting it...

...
        if(vlcPlayer){
                vlcPlayer->hide();
                delete vlcPlayer;
        }
...

The widget is hidden, no mousemoves are detected. Seems to me that it IS a mouseevent problem. Strange, but it works fine after hiding it.


Regards
Chris
