error: A data abort exception has occurred

[hisong1988]

Hi,everyone.

I want to develop a app that can play mp3 via network with Qt in my Symbian device 5230.
So I had choose Phonon and multimedia of QtMobility to have a test.

But both Phonon and multimedia are not working.

Phonon version：

Phonon::MediaObject *music = Phonon::createPlayer(Phonon::MusicCategory,Phonon::MediaSource("http://www.cenet.org.cn/userfiles/2009-2-9/20090209213949675.mp3"));
    music->play();

Phonon::MediaObject *music = Phonon::createPlayer(Phonon::MusicCategory,Phonon::MediaSource("http://www.cenet.org.cn/userfiles/2009-2-9/20090209213949675.mp3"));
    music->play();

To copy to clipboard, switch view to plain text mode 

QtMobility version：

QMediaPlayer *player=new QMediaPlayer(this);
player->setMedia(QUrl("http://www.cenet.org.cn/userfiles/2009-2-9/20090209213949675.mp3"));
player->setVolume(50);
player->play();

QMediaPlayer *player=new QMediaPlayer(this);
player->setMedia(QUrl("http://www.cenet.org.cn/userfiles/2009-2-9/20090209213949675.mp3"));
player->setVolume(50);
player->play();

To copy to clipboard, switch view to plain text mode 

I could generate the sis file. And it did't work on the 5230. I add the 5230 to debug with：
and the problem is :

Installing application...
Starting application...
Application running with pid 2222.
Process 2222, thread 2223 stopped at 0x797255b6: A data abort exception has occurred.
Finished.

P.S:I test both phonon and mediaplayer to play the local mp3 file.They worked well.
and I also test the Phonon as a Desktop version to play local mp3 file and mp3 via network. It played well.

Anyone met the problem? Or anyone would have suggestions to play mp3 via a URL with Qt for Symbian?
Thx!

Hi hisong1988,
I too am in the process of developing a media based app for Symbian.

I use Phonon and what I found was that you could not directly play a media file such as an mp3 via a URL, but instead you need to create an rtsp stream with that file then set the MediaSource to the rtsp URL.
Something like:
mediaObject->enqueue(Phonon::MediaSource(QUrl(QString("rtsp://URL_TO_YOUR_RTSP_STREAM"))));

Here's some info on RTSP

I hope that helps.
