QMedialPlayer inside the Service

[ichristophorus]

Hi, Thank you for the fantastic into into service, it works fine. But I tried to use QMedialPlayer inside the service processing and I'm not able to start the stream. I'm wondering is something is related to permissions or other problem. I tried to use this in the thread object created in main.cpp:
QMediaResource msrc(QUrl(QString("%1?serial=%2").arg(url,serial )));

QMediaContent mc2(msrc);
QMediaPlayer *theplayer = new QMediaPlayer();
theplayer -> setMedia(QMediaContent(mc2) );
theplayer ->setVolume(90);
theplayer -> play();

Maybe you have any idea concerning the issue.

Thank you again for the intro.

Regards,

Hi,

sorry for the late response, I just saw your post today. Thanks for your
kind words, I am glad that you found it helpful. Unfortunately I haven't
tried to use QMediaPlayer inside a service (however it's on my personal
roadmap). I am not an Android expert (no much experience yet) but I could
imagine that it' due to missing permissions in the AndroidManifest. You
could try to put your code into the main application (instead of the
service). Debugging your code is also much easier there (because you can
see the debugging messages there). If it works in the main application then
I would assume that the permissions are correct.

I am not 100% sure but I think that in a Android service no GUI operations
are allowed (i think it conflicts with Qt' eventloop ), so maybe
QMediaPlayer does something UI related?

Kind Regards
Bernhard

Hi,

Thank you for your hints (my delay is related to holiday).

Of course I have tried to put code inside activity part and it works as expected. I have custom debbuging procedure so all mesages are comming to file. And in the activity all works fine from the sequence point of view. But there is no event from the qmediaplayer in stream mode. When I play from the local content it works fine, having messages and playback of course. So currently I'm stuck.

I'm not Android expert as well so sometimes I'm like blind kid.

Nevertheless when I will manage the issue I will let you know.

Kinds regards,

Chris
