About load source with phonon!

[dleviathan]

I had played media from file with phonon. But now, i want play media from byte buffer to inc speed of my program. But i can't find any document show about that. Plz show me how i can play media from byte buffer with phonon.

Thanks all your help!

Seems like this would be the basic process:

• Load data into a QByteArray if you don't already have the data in a char buffer.
• Create a QBuffer, which is a QIODevice, from the QByteArray or char buffer
• Create a MediaSource from the QBuffer

Thanks Chirs!

I will try your way!

i had write code as:

QFile fileInfo(urlPath);
    fileInfo.open(QFile::ReadOnly);
    QByteArray baDuLieu = fileInfo.readAll();
    qDebug()  << baDuLieu.count();
    bufDuLieu.setData(baDuLieu);
    qDebug() << bufDuLieu.size();
//    bufDuLieu.open(QIODevice::ReadOnly);
    Phonon::MediaSource msDL(&bufDuLieu);
    _mediaObject = Phonon::createPlayer(Phonon::MusicCategory, msDL);

QFile fileInfo(urlPath);
    fileInfo.open(QFile::ReadOnly);
    QByteArray baDuLieu = fileInfo.readAll();
    qDebug()  << baDuLieu.count();
    bufDuLieu.setData(baDuLieu);
    qDebug() << bufDuLieu.size();
//    bufDuLieu.open(QIODevice::ReadOnly);
    Phonon::MediaSource msDL(&bufDuLieu);
    _mediaObject = Phonon::createPlayer(Phonon::MusicCategory, msDL);

From the MediaSource::MediaSource() docs:

Warning: On Windows, we only support QIODevices containing the avi, mp3, or mpg formats. Use the constructor that takes a file name to open files (the Qt backend does not use a QFile internally).

I had urlPath is one file .mp3. And I program on Symbian not Windows
