yadif filter, based on stefanos port of my yadif from mplayer.
Compared to stefanos, 2 frame output works with ffplay. Originally committed as revision 25196 to svn://svn.ffmpeg.org/ffmpeg/trunk

yadif is "yet another deinterlacing filter".
|

|

It accepts the syntax:
|

@example

yadif=[@var{mode}[:@var{parity}]]
|
||||
@end example
|
||||
|
||||
@table @option
|
||||

@item mode
|
||||
Specify the interlacing mode to adopt, accepts one of the following values.
|
||||
|
||||
0: Output 1 frame for each frame.
|
||||
|
||||
1: Output 1 frame for each field.
|
||||
|
||||
2: Like 0 but skips spatial interlacing check.
|
||||
|
||||
3: Like 1 but skips spatial interlacing check.
|
||||
|
||||
Default value is 0.
|
||||
|
||||
@item parity
|
||||
0 if is bottom field first, 1 if the interlaced video is top field
|
||||
first, -1 to enable automatic detection.
