video/filter: kill vf_pp (libpostproc)
This is an ancient filter, and we assume it's not useful anymore. If you really want this, it's still available in libavfilter (e.g. via --vf=lavfi=[pp...]). The disadvantage is that mpv doesn't pass through QP information to libavfilter. (This was probably the reason vf_pp still was part of mpv - it was slightly easier to pass QP internally.)

@ -231,156 +231,6 @@ Available filters are:
|
|||
``<fmt>``
|
||||
Format name, e.g. rgb15, bgr24, 420p, etc. (default: 420p).
|
||||
|
||||
``pp=[filter string]``
|
||||
Enables the specified chain of post-processing subfilters. Subfilters must
|
||||
be separated by '/' and can be disabled by prepending a '-'. Each
|
||||
subfilter and some options have a short and a long name that can be used
|
||||
interchangeably, i.e. ``dr``/``dering`` are the same.
|
||||
|
||||
.. note::
|
||||
|
||||
Unlike in MPlayer or in earlier versions, you must quote the pp string
|
||||
if it contains ``:`` characters, e.g. ``'--vf=pp=[...]'``.
|
||||
|
||||
.. admonition:: Warning
|
||||
|
||||
This filter is most likely useless on modern HD video. It might be
|
||||
helpful with old low-resolution files.
|
||||
|
||||
All subfilters share common options to determine their scope:
|
||||
|
||||
``a/autoq``
|
||||
Automatically switch the subfilter off if the CPU is too slow.
|
||||
``c/chrom``
|
||||
Do chrominance filtering, too (default).
|
||||
``y/nochrom``
|
||||
Do luminance filtering only (no chrominance).
|
||||
``n/noluma``
|
||||
Do chrominance filtering only (no luminance).
|
||||
|
||||
.. note::
|
||||
|
||||
``--vf=pp:help`` shows a list of available subfilters.
|
||||
|
||||
Available subfilters are:
|
||||
|
||||
``hb/hdeblock[:difference[:flatness]]``
|
||||
horizontal deblocking filter
|
||||
|
||||
:<difference>: Difference factor where higher values mean more
|
||||
deblocking (default: 32).
|
||||
:<flatness>: Flatness threshold where lower values mean more
|
||||
deblocking (default: 39).
|
||||
|
||||
``vb/vdeblock[:difference[:flatness]]``
|
||||
vertical deblocking filter
|
||||
|
||||
:<difference>: Difference factor where higher values mean more
|
||||
deblocking (default: 32).
|
||||
:<flatness>: Flatness threshold where lower values mean more
|
||||
deblocking (default: 39).
|
||||
|
||||
``ha/hadeblock[:difference[:flatness]]``
|
||||
accurate horizontal deblocking filter
|
||||
|
||||
:<difference>: Difference factor where higher values mean more
|
||||
deblocking (default: 32).
|
||||
:<flatness>: Flatness threshold where lower values mean more
|
||||
deblocking (default: 39).
|
||||
|
||||
``va/vadeblock[:difference[:flatness]]``
|
||||
accurate vertical deblocking filter
|
||||
|
||||
:<difference>: Difference factor where higher values mean more
|
||||
deblocking (default: 32).
|
||||
:<flatness>: Flatness threshold where lower values mean more
|
||||
deblocking (default: 39).
|
||||
|
||||
The horizontal and vertical deblocking filters share the difference and
|
||||
flatness values so you cannot set different horizontal and vertical
|
||||
thresholds.
|
||||
|
||||
``h1/x1hdeblock``
|
||||
experimental horizontal deblocking filter
|
||||
|
||||
``v1/x1vdeblock``
|
||||
experimental vertical deblocking filter
|
||||
|
||||
``dr/dering``
|
||||
deringing filter
|
||||
|
||||
``tn/tmpnoise[:threshold1[:threshold2[:threshold3]]]``
|
||||
temporal noise reducer
|
||||
|
||||
:<threshold1>: larger -> stronger filtering
|
||||
:<threshold2>: larger -> stronger filtering
|
||||
:<threshold3>: larger -> stronger filtering
|
||||
|
||||
``al/autolevels[:f/fullyrange]``
|
||||
automatic brightness / contrast correction
|
||||
|
||||
:f/fullyrange: Stretch luminance to (0-255).
|
||||
|
||||
``lb/linblenddeint``
|
||||
Linear blend deinterlacing filter that deinterlaces the given block by
|
||||
filtering all lines with a (1 2 1) filter.
|
||||
|
||||
``li/linipoldeint``
|
||||
Linear interpolating deinterlacing filter that deinterlaces the given
|
||||
block by linearly interpolating every second line.
|
||||
|
||||
``ci/cubicipoldeint``
|
||||
Cubic interpolating deinterlacing filter deinterlaces the given block
|
||||
by cubically interpolating every second line.
|
||||
|
||||
``md/mediandeint``
|
||||
Median deinterlacing filter that deinterlaces the given block by
|
||||
applying a median filter to every second line.
|
||||
|
||||
``fd/ffmpegdeint``
|
||||
FFmpeg deinterlacing filter that deinterlaces the given block by
|
||||
filtering every second line with a (-1 4 2 4 -1) filter.
|
||||
|
||||
``l5/lowpass5``
|
||||
Vertically applied FIR low-pass deinterlacing filter that deinterlaces
|
||||
the given block by filtering all lines with a (-1 2 6 2 -1) filter.
|
||||
|
||||
``fq/forceQuant[:quantizer]``
|
||||
Overrides the quantizer table from the input with the constant
|
||||
quantizer you specify.

||||
fast pp filter combination (h1:a,v1:a,dr:a)
|
||||

high quality pp filter combination (ha:a:128:7,va:a,dr:a)
|
||||
|
||||
.. note::
|
||||
|
||||
This filter is only available if FFmpeg/Libav has been compiled
|
||||
with libpostproc enabled.
|
||||
|
||||
.. admonition:: Examples
