[SOLVED] QtMultimedia : defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"
-
Make sure wmfengine.dll isn't in the mediaservice directory. I currently only have build a debug version of dsengine (dsengined.dll). If you want, I can send you that one for evaluation.
I'm currently adding a -no-wmf-backend configuration flag for configure, to simplify this building process.

Reminder : these particular instructions are supposed to work for windows. If you have similar issues on Linux the solution seems to be to install libgstreamer.
So for those who have the same issue as I did :
-Dowload and extract the "qtmultimedia submodule" (for the corresponding version of Qt) from the Qt archives
-Delete the following line in the plugins.pro file:
config_wmf: SUBDIRS += wmf-Change in the directshow.pro file:
!config_wmf: include(player/player.pri)into
include(player/player.pri)-Compile it all (with the same verison of MSVC you use to compile your program)
-Copy the resulting mediaservice folder next to your executableI have only tested this solution on Qt 5.1 but I don"t see why it shouldn't work on later versions.

Hi. I'm experiencing the same problem. My config is:
- Windows Vista 64bit
- qt-windows-opensource-5.1.0-msvc2010-x86-offline.exe
@raf924 So you're saying the wmf engine nor the ds engine from the official 5.1 SDK build does not work? Do I really have to compile it myself? Is perhaps the MinGW SDK version worh a shot?
Thanks.

Well it seems that it doesn't work. Maybe there is some tweak to perform on your machine to have it working but i think it easier to just recompile the multimedia module with the aforementionned modifications, if you want to use msvc as a compiler. I should point out that the reason i prefer using msvc rather than mingw in this case is that you can't get the metadata with the latter, or at least i couldn't. But if you don't care about getting the metadata from the Qt lib, yes i suggest you use MinGW.

I am still seeing this problem.
defaultServiceProvider::requestService(): no service found for - "org.qt-project.qt.mediaplayer"
Qt 5.1.1
QCreator 2.8.1
Os win7 x64
Target Windows Surface 2 Pro (Win8.1 x64)I have tried the above fix with no success. Any suggestions for isolating what the problem may be? I have tried with WAV and WMA sound clips.

Hi, I'm experiencing the same problem on building Static.
I descriped my problem in the next link.
http://qt-project.org/forums/viewthread/40102/Solutions above won't work for me

Well, I believe it should be rather simple to fix your problem. You just need to apply the modifications to the source as indicated then build it statically then copy the result in your static Qt folder. I am by no means certain it will work but I think it should.

Sorry, I'm nube in QT
This is QT folder that runs Static "C:\Qt\Static\5.2.0"
This is source folder it build from "C:\Qt\Static\src\qt-everywhere-opensource-src-5.2.0".
Now, I have to
-Dowload and extract the qtmultimedia submodule [download.qt-project.org]
to "C:\Qt\Static\src\qt-everywhere-opensource-src-5.2.0\qtmultimedia"
-Delete the following in the plugins.pro file:
config_wmf: SUBDIRS += wmf
-Change in the directshow.pro file:
!config_wmf: include(player/player.pri)
into
include(player/player.pri)go to "C:\Qt\Static\src\qt-everywhere-opensource-src-5.2.0\qtmultimedia" with MinGW and run "qmake" command to compile it?
And than copy some resulting folder to "C:\Qt\Static\5.2.0" ?

Hi,
Do you have a feedback on that (even though I tried)?
Cause I've been trying to build a static 5.2.1 but so far, i can't get qtmultimedia to work...
(defaultServiceProvider::requestService(): no service found for - “org.qt-project.qt.mediaplayer”)
Of course everything works perfectly on the dynamic side.[quote author="Mega4alik" date="1395811707"]Sorry, I'm nube in QT

[/quote]Hi, I couldn't make it work with MINGW. Currently I'm trying to build it with MSVC. I will post after I get some results.

Hi
I followed this solution step by step. but didn’t get a success. I compiled using mscv2012.
Qt 5.2.1
QCreator 3.0.1
Os win8 ×64
I don’t have much knowledge in qt and can’t imagine what i could miss. I need to have audio playback by Url, but i can’t play any local wav, mp3 as well.
