Sound not working

[wehbi]

I am developing a game that contains many sounds
but the sound is not working
i am using this code

.pro

CONFIG += mobility
MOBILITY += multimedia

Header

#include <qmediaplayer.h>
#include <qmediaplaylist.h>

private slots:
void statusChanged(QMediaPlayer::MediaStatus status);
private:
QMediaPlayer *player;
QMediaPlaylist *playlist;

.cpp

#include <qurl.h>


MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);




player = new QMediaPlayer(this);
player->setVolume(50); // set Volume
playlist = new QMediaPlaylist(this);
playlist->setMediaObject(player);

connect(player, SIGNAL(mediaStatusChanged(QMediaPlayer::MediaStatus)),
this, SLOT(statusChanged(QMediaPlayer::MediaStatus)));

playlist->addMedia(QUrl::fromLocalFile("c:\\test.mp3")); // you can add as many media files as you want

player->play();


}

MainWindow::~MainWindow()
{
delete ui;
}
void MainWindow::statusChanged(QMediaPlayer::MediaStatus status) {
switch (status) {
case QMediaPlayer::LoadedMedia:
player->play();
break;
default:
break;
}
}

i got this code from this link:
http://wiki.forum.nokia.com/index.ph...ng_Qt_Mobility


error is:
virtual bool QMediaPlaylist::setMediaObject(QMediaObject *object) is protected
within the context


please help

You can simply use QSound:lay("myfile.wav"); to play the sound?
It should support mp3.

There might be slight delay and in some cases doing it this way is not recommended, but for simple game it should be more than usable.
After all, you could change the implementation later on, but atleast continue your development now and change to something else later if this is not enough for you.

teemup when i used QSound i heard a sound like error sound in windows xp , the sound is mp3 format ... its not working

I remembered reading it somewhere that QSound works only with .wav file. I also have tried playing sound with QSound but I failed and then i switched to phonon.

but can you try this simpler version.

QMediaPlayer *player = new QMediaPlayer;
player->setMedia(QUrl::fromLocalFile("test.raw"));
player->setVolume(50);
player->play();

Phonon was the old module,,,,,
Now You have to use Qt Multimedia API under Qt Mobility......

See this example here .mp3 file is working : http://wiki.forum.nokia.com/index.ph...ng_Qt_Mobility

have u used this code before? , please if u have the correct code help me .
Thank u

[rahulvala]

Have you gone through the article ,I suggested to you ?

By the way,,,Show us the code and your .pro file ?
So that we can help better ?

following is simple code to play sound using phonon.

Phonon::MediaObject *music =
Phonon::createPlayer(Phonon::MusicCategory,
Phonon::MediaSource("/path/mysong.mp3"));
music->play();

add following in pro file
QT += phonon

Hello,
sorry for my late reply.

If you can live with a bit of Symbian-only code in your app, this snippet will work perfectly:

thanks its working , what i do is i used phonon
before it doesnt work because i tested application in a simulater , but when tested the it in a desktop its working.

but i face another issue , how to play the sound in a continuous playback until i decide to stop or pause, because in the game the sound sho always repeated.

[kunal_the_one]

one solution might be, you can listen to finished signal from MediaObject and as soon as you get finished signal, you can put request to play again. There is also aboutToFinish signal, you might try using this as well.

[kamalakshan]

You can observe the status of the media being played and run it in a loop.

[wehbi]

thank u kunal i got the idea , its the best way to listen to the finish signal and replay the sound .
