用qt显示视频.qt video

QPainter has a method called drawImage. You can do something like the 

following in a subclass of QWidget:




void VideoWidget::paintEvent()

{

//Get
 the current frame and size data...


//Passing QImage

QImage frame(frameDataUCharPtr, frameWidth, frameHeight. 

QImage::Format_RBG32 );


QPainter painter(this);

painter.drawImage(rect(), frame);


}


Under Qtopia
 you can use QDirectPainter to write directly to framebuffer 


memory and get
 some faster access for drawing frames. You will have to 

do the color conversions yourself to get
 the frame into your 

framebuffer's color model.
