Help displaying frames from a webcam to the screen

[stealth86]

You will need to convert the input frame pixel by pixel from YUV( yes, YUV ), to RGB( meaning you store the pixel data to a QImage or QPixmap ).

Information about conversion formulas you can find here:
http://en.wikipedia.org/wiki/YUY2,
http://www.fourcc.org/fccyvrgb.php, and here
http://www.fourcc.org/fccyvrgb.php.

First you need to initialize the QImage to the dimensions of the frame, Next you just process the frame starting from the first pixel, and set the RGB data at the corresponding location in the QImage.

Regards

Are there any libraries that perform the conversion between YUY2 and RGB that I could just link in?

nvm: I just found the libavcodec library.
