... | ffmpeg -f yuv4mpegpipe -i -
but ffmpeg probably guesses right without specifying -f for
input.

Something like
... | yuvdeinterlace \
| y4mscaler -v 0 -O sar=src -O chromass=444 \
| y4mstabilizer \
| y4mscaler -v 0 -O sar=src -O chromass=420_MPEG2 \
| ffmpeg -i - -target pal-dv -y test.dv
might get you going.

I don't know.
