Dragon Player doesn't

I don't use Dragon Player normally but I was looking at it just now.
When I right-click on a video file, select play with then choose Dragon
Player to play it, it launches Dragon Player but doesn't play the file.
When I select Play File from within Dragon Player, I can select a video
to play, but again it doesn't play it.

Has anyone else experienced this problem and/or come across a fix for it?

I hadn't even heard of Dragon Player, but I have come across a
situation where a video won't play because either the player
or another active program has grabbed exclusive access to the
audio device. IIRC the player would at least display the first
frame of the video, but just sit there.

Cheers,
David.

I can only say that on Debian unstable (Bookworm) it plays the video but no audio while VLC plays video and audio.
I didn't bother to look into the audio problem, however.

I dont' use this program, but if you run it via terminal, what does it say?

Good point. I get a lot of error messages that say "WARNING: bool
Phonon::FactoryPrivate::createBackend() phonon backend plugin could not
be loaded". There are other messages that also mention phonon, like this
sequence:
WARNING: Phonon::createPath: Cannot connect Phonon::MediaObject ( no
objectName ) to Phonon::VideoWidget ( no objectName ).
WARNING: bool Phonon::FactoryPrivate::createBackend() phonon backend
plugin could not be loaded

WARNING: Phonon::createPath: Cannot connect Phonon::MediaObject ( no
objectName ) to Phonon::AudioOutput ( no objectName ).

Along with numerous other messages, including several similar to:

kf.coreaddons: no metadata found in
"/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/metainfo.so" "Failed to
extract plugin meta data from
'/usr/lib/x86_64-linux-gnu/qt5/plugins/kf5/kio/metainfo.so'"

Dragonplayer is part of the KDE set up.
I installed Falkon and couldn't understand why it had almost zero configuration options.
It wasn't until I installed konq-plugins they finally appeared.
I think KDE needs to pick up its game a little, in its ability to pull in dependencies.
Needing to do a full KDE install in order to run a browser or video player is a little too much to expect, and having to hunt around for obscure necessities harks back to the dark ages, somewhat.
Cheers!

Do you have the phonon4qt5 plugin(s) installed?

Please report this bug then on Debian Bug tracking system, against
"Falkon", so installing this package pulls "konq-plugins", this is easy fix.

Please report on Debian BTS against Dragon Player then, include all
terminal outputs and other system logs, if there is anything interesting
there. Use "reportbug" package to do that.
Also you may want to try Dragon Player on another machine before
submitting bug, to make sure this is not your setup at fault. And/or you
can try Bookworm see how it works there with newer version.
