 +<code>
 +parity
 +The picture field parity assumed for the input interlaced video. It accepts one of the following values:
 +
 +0, tff
 +Assume the top field is first.
 +
 +1, bff
 +Assume the bottom field is first.
 +
 +-1, auto
 +Enable automatic detection of field parity.
 +
 +The default value is auto. If the interlacing is unknown or the decoder does not export this information, top field first will be assumed.
 +
 +deint
 +Specify which frames to deinterlace. Accept one of the following values:
 +
 +0, all
 +Deinterlace all frames.
 +
 +1, interlaced
 +Only deinterlace frames marked as interlaced.
 +
 +The default value is all.

 +Default for ''mode'' is ''send_frame'', which will output one frame for each frame; the output frame rate is constant at 30000/1001 (29.97, NTSC).

 +If I set it to create a frame for each field (''mode=send_field''), it will come out at 60000/1001 constant instead (59.94).
