As far as I know, no, there is not.

yuv4mpeg is not even video only: the output stream is reset when mplayer
detects a framerate change, for example. A lot of NTSC content will be
unusable.

Not supporting a mediocre OS is not the worst problem here. Having two FIFOs
from a process to another is a sure way to end up with a process blocked
writing in one FIFO while the other is blocked reading in the second FIFO.

I understood the original suggestion like this:

- Imitate -vo yuv4mpeg to implement -vo stream, which muxes the raw video
  frames in a format more robust and complete than yuv4mpeg; maybe nut. At
  the very least, it needs to support accurate timestamps and muxing with
  audio.

- Imitate -ao pcm:fast to implement -ao stream, which muxes the PCM samples
  in the same stream as above.

- Use mplayer -vo stream:file=fifo -ao stream $input.
