lavfi: port mp=pp7 to libavfilter
The only difference with mp=pp7 is that default mode is "medium", as stated in the MPlayer docs, rather than "hard". Signed-off-by: Stefano Sabatini <stefasab@gmail.com>

@section pp7
|
||||
Apply Postprocessing filter 7. It is variant of the @ref{spp} filter,
|
||||
similar to spp = 6 with 7 point DCT, where only the center sample is
|
||||
used after IDCT.
|
||||
|
||||
The filter accepts the following options:
|
||||
|
||||
@table @option
|
||||
@item qp
|
||||
Force a constant quantization parameter. It accepts an integer in range
|
||||
0 to 63. If not set, the filter will use the QP from the video stream
|
||||
(if available).
|
||||
|
||||
@item mode
|
||||
Set thresholding mode. Available modes are:
|
||||
|
||||
@table @samp
|
||||
@item hard
|
||||
Set hard thresholding.
|
||||
@item soft
|
||||
Set soft thresholding (better de-ringing effect, but likely blurrier).
|
||||
@item medium
|
||||
Set medium thresholding (good results, default).
