Problem with Qt Multimedia

[6EQUJ5]

@SGaist I installed all the packages that came up with that command. gst-play-1.0 still doesn't work.

[SGaist]

What doesn't work ?

You can't read the file using the command ?

[6EQUJ5]

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

[SGaist]

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.

[6EQUJ5]

@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!

[SGaist]

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

[6EQUJ5]

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

[SGaist]

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).

[6EQUJ5]

@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.

[SGaist]

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