Problem with Qt Multimedia
-
@SGaist I did that and the same error happens.
-
Can you play that file with the gstreamer tools directly ?
-
@SGaist How would I do that?
-
gst-play-1.0 your_video_file
-
@SGaist The command doesn't exist. Even though I installed
libgstreamer1.0-dev.
-
That's the development package to be able to use the library in your own projects. You need to install the GStreamer tools.
-
@SGaist What package do I need to install for the GStreamer tools?
-
Please learn to use the tools from your distribution
apt-cache search gstreamer | grep tools.
-
@SGaist I installed all the packages that came up with that command.
gst-play-1.0still doesn't work.
-
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-appsand 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-1.0to work but came up with nothing.Installing
gstreamer1.0-plugins-base-appsallowed me to use thegst-play-1.0command. 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 dmesgis here: https://pastebin.com/VY243fPhAlso, 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.
-
@SGaist New output (after getting logged out): https://pastebin.com/yJK4tFeQ
Output of
diff dmesgOutputBeforeLogout.txt dmesgOutputAfterLogout.txt: https://pastebin.com/5jGtEiUd (differences between two outputs)
