ffplay test.avi -vf yadif=1

does not work for me, too.

I need the same behaviour like in WMP, when I use LAV filter 
(deinterlacding ON, force, TopFieldFirst preset).
With this filter I get a perfect deinterlacing with the behavior of old 
tupe reference monitors.

And I want to use same in FFplay.
