This is perhaps similar to the problems I had getting
QMediaRecorderworking on the BlackBerry10 for audio recording?

At application initiatlization, I noticed errors like:

> default   9000  defaultServiceProvider::requestService(): no service found

Without this service setup, various operations using the recorder will
fail.

Equivalent code can be found at http://www.qt.gitorious
.org/qt-mobility/qt-mobility/blobs/master/examples/audiorecorder/
audiorecorder.cpp and this fails in the same way, in the call

    audiosource = new QAudioCaptureSource(this);

Internally, Q_MEDIASERVICE_AUDIOSOURCE is set to "com.nokia.qt.audiosource"
and
Q_MEDIASERVICE_CAMERA is set to "com.nokia.qt.camera" in http://www.qt.
gitorious
.org/qt-mobility/qt-mobility/blobs/f7071081b7a83e42033df57d17593c3fd3e70608/
src/multimedia/qmediaserviceprovider.h

So the question is do you have an implemented and working com.nokia.qt.
audiosource and com.nokia.qt.camera , or does your implementation of
QMediaServiceProvider provide a working alternative audiosource and camera?

PS: Any suggestions on getting QMediaRecorder working on the BlackBerry10
platform? Is anyone working on a com.rim.audiosource implementation
anywhere? (Wish BlackBerry put more effort into getting standard QtMobility,
QtMultiMedia, QtLocation capabilities completely working on their platform.
).
