Does xvidcap get the array of pixels from the xserver or off the video cards buffer?
xvidcap cannot at this point in time make use of hardware acceleration! xvidcap can only get a frame from the X server either using plain X11 calls or Xshm (with shared memory, which requires client and server to be on the same machine). The thing is that once the actual bitmap is on the frame buffer, I don’t know how to get it at all, or even in a portable fashion. I’ve heard that AGP should offer ways, but then AGP slots don’t seem to be the fashion anymore these days, anyway. If you know how to get at a bitmap once it’s rendered by the frame buffer and are confident that getting at it won’t eat all the performance gain, DO TEACH ME!
