For H.264 you can use ext_pipe command, like this:
extpipe x264 - --input-res %wx%h --fps %fps --bitrate 6000 --preset
ultrafast --quiet -o %f.mp4
The advantage of ext_pipe is that you can use whatever encoder that
supports raw frames from stdin, and second - you utilize more than just one
CPU core which gives you huge performance boost on multi-core devices.
