Software reduction means you grab the whole 704 by 576 (when PAL) pixels for every frame, copying from the mmap-ed buffers to your own buffer. Then you skip say 3 out of every 4 lines, and in the lines you keep, skip 3 out of every 4 pixels. There are subtler methods but this one is simple. If you wish to use ready-made encoders I suggest mencoder (www.playerhq.hu) or ffmpeg (ffmpeg.sourceforge.net). Both have options to specify the zoom-down factor between the grabber and the image to be encoded. I also know of transcode and nvrec, but havent used them.
