qmediaplayer object does not have a valid service

SGaist

Hi and welcome to devnet,

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

@raf924

@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!
