Problem with playing sound via ffmpeg backend
-
Hello,
I have a problem playing sound on Arch linux under Plasma 6.5.3I would like to add a sound to accompany an animation in the libreoffice impress and having problems.
When I select the sound from the animation effect it plays just fine when select the play button in the menu.
However, when I start the presentation, there is no sound coming out.
I get this error from the console.qt.multimedia.ffmpeg.mediadataholder: Could not open media. FFmpeg error description: Immediate exit requested.Strangely, when I insert the same sound as a standalone Audio/Video into the presentation it plays fine.
Also when I play the sound directly from the command line it plays find. I use this command:
ffplay /usr/lib/libreoffice/share/gallery/sounds/nature1.wavWhy is this happening?
I don't know enough about linux to investigate further.

Hi and welcome to devnet,
Which version of Qt does libreoffice use on your machine ?
One other thing you can do is enable logging for all QtMultimedia. That might give you some additional clue about what is happening. -
Hello SGaist,
I think it uses qt6. How do I find out?
Also, how do I enable logging for QtMultimedia?
Interestingly, when start libreoffice with this environmental variable to set backend for gstreamer, the sound is working
QT_MEDIA_BACKEND=gstreamer libreoffice --impressI found it in another post with similar problem which apparently was fixed by the last QT update

You can run ldd on your libreoffice binary to see which libraries are linked.
To enable logging categories, you have the different options describe in the documentation.
