Updated, I moved the x86 code to a new libavfilter/x86 dir, and added
documentation for the mode and parity parameters.

Now I see that the implementation is incomplete.  The functionality
implemented in the libmpcodec yadif function continue_buffered_image()
is not implemented in the current code.

The mode parameter allows to set how to output image:
    /**
     * 0: send 1 frame for each frame
     * 1: send 1 frame for each field
     * 2: like 0 but skips spatial interlacing check
     * 3: like 1 but skips spatial interlacing check
     */
    int mode;

Currently mode is checked only in filter_line_c() like this:
        if (yadif->mode < 2) {
        ...
        }

for enabling/disabling the spatial interlacing check (whatever it is).

Regards.
