I can execute the .sh file and it works but the images and videos won't be shown.I would like to know which shared libraries and dependencies should I need to add more.Thanks.

    Hi,

    What type of videos ? Depending on that, you might need to have additional codecs on the target machine.
    Did you also checked that you deploy the Qt Multimedia plugins along your application ?

    There will be video player and image viewer in my app,when I load the video or image I can't see anything in the video player and image viewer. Is it enough to deploy libQtMultimedia.so.5 and libQtMultimedia.Widgets.so.5 for the videos and images??

    No, as suggested in my previous post, you have to deploy the Qt Multimedia plugins.

    Did you use windeployqt to prepare your application for deployment ?
