VideoCapture#grab Source

Hi,

where can I find the source for the VideoCapture#grab implementation? I'd like to know if I can encoded frames too, instead of having to retrieve() a decoded version. Why: I need to store a certain, large, number of frames (/question/112096/videocapture-frames-videocapture-possible/) and read them one by one. I can't find a way to simply put specific frames of a VideoCapture into another VideoCapture, and I don't want to store them to files first to only read them a bit later.

@LBerger I know, but I could not find the implementation of the VideoCapture class. Only its declaration.

@LBerger Aw, too bad that the implementation isn't as straightforward as I had hoped. Oh well, guess I need to dig deeper.

If you work with a debugger you can find implementation
