no service found for - org.qt-project.qt.mediaplayer

[IL]

Hello,
I am trying to display video on my Linux embedded ARM system (Beaglebone like).
After a lot of messing around, I was able to compile gstreamer 1.0 for my embedded platform, I also able to see after running ./configure that gstreamer is going to compile (gstreamer ........yes (1.0) something like that)
I have compiled my QtMultimedia (running make module-qtmultimedia) using my relevant toolchain and it also include gstreamer. When compilation done, I have found libqgsttools_p.so under qtmultimedia/lib/ include libQt5Multimedia.so and libQt5MultimediaWidgets.so.
After loading my application include QT libraries I am getting the above message "no service found for - org.qt-project.qt.mediaplayer"
I think that the application don't find gsttools.so.
How can I make sure that the gst plugin location is OK?
Can I inform QT about plugins locations?
I think that I don’t have enough debug information from the system, how can i get more logs from my embedded device?
BTW this video is running well on my Fedora 20

Please advise!

More information, currently I link libqgsttools_p.so with all other QT libs, It ask me to add all depended libs such: gstreamer, gobject, gmodule gstapp, gsttag, gstaudio, gstvideo, gstbase etc...
After adding all those libraries, the linking complete successfully.

Please advice.

@IL To resolve your issue you just need to install the developper package of gstreamer (either libgstreamer-dev or devel-gstreamer depending on your package manager)

[IL]

@raf924
Thanks for your replay.
You mean that I need to install that on my target machine?
How can I know that?
Is there any debug flag that can be open and point on it?
Currently it just said that it missing plugins even though I have set all.
I am checking…

Thanks again!!!

[raf924]

@IL Yeah you need to install it on the target. I don't know why though. It should only need the runtime package of gstreamer. I had a similar problem on windows and someone posted that solution for linux.

[IL]

@raf924
dose it need the libs file only from the package? like libgio, libglib, libgmodule, libgobject etc...
or also the include folder and all other stuff?

Thanks!

[raf924]

@IL i don't know but i think only the .so files, though the package manager will install everything anyway

[IL]

@raf924
Hi, I have installed gstreamer1-devel package but nothing changed.
any idea?

IL

[raf924]

@IL Did you also install libgstreamer? I know it seems redundant but this is the only thing that i know of that can solve this problem on Linux.

[IL]

@raf924
Hi, yes i already install libgstreamer, it is look like that my problem was that the plugins for the video should be located under lib/mediaservise and not flat under lib/
But now, unsurprisely, I have new issue that crushes my target Linux:
Inconsistency detected by ld.so dl-open.c 271 dl_open_worker...
I now will take a look and try to resolve it.

Thanks a lot for your time, I really appreciate that.
