Detailed Description

Base class for custom media data streams.

Implement this class to provide a custom data stream to the backend. The class supports both, the push and the pull model.

Push:

PushStream::PushStream(QObject *parent)
{
setStreamSize(getMediaStreamSize());
connect(m_timer, SIGNAL(timeout()), SLOT(moreData()));
m_timer->setInterval(0);
}
void PushStream::moreData()
{
const QByteArray data = getMediaData();
if (data.isEmpty()) {
endOfData();
} else {
writeData(data);
}
}
void PushStream::needData()
{
m_timer->start();
moreData();
}
void PushStream::enoughData()
{
m_timer->stop();
}
Base class for custom media data streams.
bool isEmpty() const const
QObject * parent() const const
T qobject_cast(QObject *object)

Pull:

PullStream::PullStream(QObject *parent)
{
setStreamSize(getMediaStreamSize());
}
void PullStream::needData()
{
const QByteArray data = getMediaData();
if (data.isEmpty()) {
endOfData();
} else {
writeData(data);
}
}

Constructor & Destructor Documentation

◆ AbstractMediaStream2() [1/2]

Phonon::AbstractMediaStream2::AbstractMediaStream2 ( QObject * parent = 0)
explicitprotected

Constructs an AbstractMediaStream2 object with a parent.

Definition at line 108 of file abstractmediastream2.cpp.

◆ AbstractMediaStream2() [2/2]

Member Function Documentation

◆ event()

bool Phonon::AbstractMediaStream2::event ( QEvent * e)
protectedvirtual

Reimplemented from QObject.

Definition at line 35 of file abstractmediastream2.cpp.

◆ needData()

virtual void Phonon::AbstractMediaStream2::needData ( quint32 size)
protectedpure virtual

Reimplement this function to be notified when the backend needs data.

When this function is called you should try to call writeData or endOfData before returning.

Parameters
sizeThe number of bytes that are needed. If possible, pass size bytes of media data in the next writeData call.

◆ resetDone()

void Phonon::AbstractMediaStream2::resetDone ( )
protected

Definition at line 140 of file abstractmediastream2.cpp.

◆ seekStreamDone()

void Phonon::AbstractMediaStream2::seekStreamDone ( )
