    What doesn't work ?

    You can't read the file using the command ?

    @SGaist The command still doesn't exist according to the terminal even with sudo.

      Seriously, did you even try to search where that file could be found ?

      In this case it's the package gstreamer1.0-plugins-base-apps and the tools package is a dependency of that one.

        @SGaist I'm sorry. I may be at least an amateur programmer, but I'm definitely not a Linux expert, so I lack knowledge. I tried googling to get gst-play-1.0 to work but came up with nothing.

        Installing gstreamer1.0-plugins-base-apps allowed me to use the gst-play-1.0 command. But, when I try to play a video file (MP4) the same thing happens! I get logged out!

          Then you have determined that it's not a Qt problem. There's something fishy going on with your machine.

            @SGaist It works fine in Windows 10 though. What could possibly be wrong with Debian Linux?

              You are comparing apple to oranges. Both are completely different OSs with completely different multimedia backends.

              I don't know what is going on with your Debian but you sure have something either misconfigured or buggy. However, it's not something Qt related. You should check with the Debian folks.

                @6EQUJ5 I would guess bad graphics driver.
                You could check the output of dmesg command. In general you should ask this question in a Debian forum or mailing list and attach information about your system (especially graphics hardware).

                  @SGaist I will do that.

                  @jsulm The output of sudo dmesg is here: https://pastebin.com/VY243fPh

                  Also, I will ask for help on Debian mailing list/forum with the output.

                    Compare it with the output of dmesg after you got kicked of your session.
