I have no real experience with capturing on Windows, but there's also the dshow and the vfwcap input devices. > I'm very performance conscious for my scenario (minimize CPU), is there an > alternative to gdigrab that is less CPU intense? It's probably not gdigrab, but the actual conversion? There are many things you can do: - reduce frame rate (may have little effect if the video content doesn't change much anyway). - reduce resolution - use a less CPU intense codec, or better - tune the codec to use less quality (which usually means less CPU) - tune the codec to use more bandwidth (which usually means less CPU) - use a hardware (assisted) codec - ... If your encoding to FLV uses H.264 as video codec, you could try adding "-preset ultrafast" (or "fast" or "faster") and watch the required bandwidth explode. ;) > Bonus round lol --- Can anybody explain (or direct me to some reading > material which would explain) what is happening under the covers here? LOL indeed! Which part of the covers?
