qmediaplayer object does not have a valid service

[raf924]

@ilan-lisha Install libgstreamer through your package manager

[IL]

@raf924 - I already have gst on my Fedora, any other idea?
thanks for your response.

[IL]

@ilan-lisha I have libgstreamer-0.10.so.0 - libgstreamer-0.10.so.0.30.0

[IL]

@ilan-lisha I also see the error
Starting /home/.../qt-video-apps/build-videowidget-QT5_5_0-Debug/videowidget...
defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"

[raf924]

@ilan-lisha the solution to this problem is the one i recommended i don't know of any other, try installing any package related to gstreamer and libgstreamer.

Hi and welcome to devnet,

Check the multimedia plugin with ldd, it should indicate what might be missing on your system.

@SGaist Hi and Thanks,
That's what I get from the multimedia.so using LDD command

@raf924
can you tell please what is the different between gstreamer and libgstreamer?

@ilan-lisha
could it be the reason?
While running ./configure -v -qt-xcb -gstreamer -opensource
I get the error: project ERROR: gstreamer-0.10 development package not found
even though libgstreamer-0.10.so.0.30.0 is installed in my system.
In my old configuration: GStreamer .............. no

[IL]

@IL
Please advice what should I do?

[SGaist]

As silly as it may sound: Install the gstreamer development package

[IL]

@SGaist - As I have mention above, gstreamer package already installed on my PC.
Any idea why QT don’t recognize it?

[raf924]

@IL He 's not talking about the gstreamer package but rather libgstreamer-dev or something like that. Right?

[SGaist]

@raf924's right, the dev packages are needed

[IL]

@SGaist Hi
Sorry for the ignorance but can you tell the different between gstreamer package and gstreamer-dev package?
Do I need here qt-gstreamer?

Thanks!

[IL]

@raf924 Hi
I am running:
./configure -v -qt-xcb -opensource -confirm-license -gstreamer
currently configuration failed for:
GStreamer 0.10 auto-detection... ()
Project ERROR: gstreamer-audio-0.10 development package not found
GStreamer 0.10 disabled.

also I can see that according to gstreamer.pro it required:
gstreamer-0.10
gstreamer-base-0.10
gstreamer-audio-0.10
gstreamer-video-0.10
gstreamer-pbutils-0.10
I have managed to install gstreamer-0.10 and gstreamer-base-0.10 but now I am stuck on audio and video.
I am running QT on fedora 20.
I cannot find gstreamer-audio/video using "yum install ... "
What am I missing?
Please advice for a solution.

best regards, IL

[raf924]

@IL sudo yum install gstreamer-devel should do the trick

[IL]

@raf924 Thanks!
