The picture looks green with QImage

The pBuf is from web camera. Please see below:

QImage image(pBuff, 320, 240, 320*3, QImage::Format_RGB888);
mpLbl->setPixmap(QPixmap::fromImage(image));

The label can display this vedio successful, but it looks green against to normal.
What is the problem?

Perhaps your webcam produces BGR-frames? In that case try

Code:

---

mpLbl->setPixmap(QPixmap::fromImage(image.rgbSwapped()));

---
