+ffmpeg can also take dshow (DirectShow) as input by creating an avisynth file (.avs file) that itself gets input from a graphedit file, which graphedit file exposes a pin of your capture source or any filter really, ex ("yo.avs"):

+Also this note that "The input string is in the format video=<video device name>:audio=<audio device name>. It is possible to have two separate inputs (like -f dshow -i audio=foo -f dshow -i video=bar) but my limited tests had shown a better synchronism when both were used in the same input."
