VIDEO FILTERS ============= Video filters allow you to modify the video stream and its properties. The syntax is: ``--vf=`` Setup a chain of video filters. You can also set defaults for each filter. The defaults are applied before the normal filter parameters. ``--vf-defaults=`` Set defaults for each filter. .. note:: To get a full list of available video filters, see ``--vf=help``. Also, keep in mind that most actual filters are available via the ``lavfi`` wrapper, which gives you access to most of libavfilter's filters. This includes all filters that have been ported from MPlayer to libavfilter. Video filters are managed in lists. There are a few commands to manage the filter list. ``--vf-add=`` Appends the filters given as arguments to the filter list. ``--vf-pre=`` Prepends the filters given as arguments to the filter list. ``--vf-del=`` Deletes the filters at the given indexes. Index numbers start at 0, negative numbers address the end of the list (-1 is the last). ``--vf-clr`` Completely empties the filter list. With filters that support it, you can access parameters by their name. ``--vf==help`` Prints the parameter names and parameter value ranges for a particular filter. ``--vf=`` Sets a named parameter to the given value. Use on and off or yes and no to set flag parameters. Available filters are: ``crop[=w:h:x:y]`` Crops the given part of the image and discards the rest. Useful to remove black bands from widescreen videos. ``,`` Cropped width and height, defaults to original width and height. ``,`` Position of the cropped picture, defaults to center. ``expand[=w:h:x:y:aspect:round]`` Expands (not scales) video resolution to the given value and places the unscaled original at coordinates x, y. ``,`` Expanded width,height (default: original width,height). Negative values for w and h are treated as offsets to the original size. .. admonition:: Example ``expand=0:-50:0:0`` Adds a 50 pixel border to the bottom of the picture. ``,`` position of original image on the expanded image (default: center) ```` Expands to fit an aspect instead of a resolution (default: 0). .. admonition:: Example ``expand=800::::4/3`` Expands to 800x600, unless the source is higher resolution, in which case it expands to fill a 4/3 aspect. ```` Rounds up to make both width and height divisible by (default: 1). ``flip`` Flips the image upside down. ``mirror`` Mirrors the image on the Y axis. ``rotate[=0|90|180|270]`` Rotates the image by a multiple of 90 degrees clock-wise. ``scale[=w:h:param:param2:chr-drop:noup:arnd`` Scales the image with the software scaler (slow) and performs a YUV<->RGB color space conversion (see also ``--sws``). All parameters are optional. ``:`` scaled width/height (default: original width/height) :0: scaled d_width/d_height :-1: original width/height :-2: Calculate w/h using the other dimension and the prescaled aspect ratio. :-3: Calculate w/h using the other dimension and the original aspect ratio. :-(n+8): Like -n above, but rounding the dimension to the closest multiple of 16. ``[:]`` (see also ``--sws``) Set some scaling parameters depending on the type of scaler selected with ``--sws``:: --sws=2 (bicubic): B (blurring) and C (ringing) 0.00:0.60 default 0.00:0.75 VirtualDub's "precise bicubic" 0.00:0.50 Catmull-Rom spline 0.33:0.33 Mitchell-Netravali spline 1.00:0.00 cubic B-spline --sws=7 (Gaussian): sharpness (0 (soft) - 100 (sharp)) --sws=9 (Lanczos): filter length (1-10) ```` chroma skipping :0: Use all available input lines for chroma (default). :1: Use only every 2. input line for chroma. :2: Use only every 4. input line for chroma. :3: Use only every 8. input line for chroma. ```` Disallow upscaling past the original dimensions. :0: Allow upscaling (default). :1: Disallow upscaling if one dimension exceeds its original value. :2: Disallow upscaling if both dimensions exceed their original values. ```` Accurate rounding for the vertical scaler, which may be faster or slower than the default rounding. :no: Disable accurate rounding (default). :yes: Enable accurate rounding. ``dsize[=w:h:aspect-method:r:aspect]`` Changes the intended display aspect at an arbitrary point in the filter chain. Aspect can be given as a fraction (4/3) or floating point number (1.33). Note that this filter does *not* do any scaling itself; it just affects what later scalers (software or hardware) will do when auto-scaling to the correct aspect. ``,`` New aspect ratio given by a display width and height. Unlike older mpv versions or MPlayer, this does not set the display size. Can also be these special values: :0: original display width and height :-1: original video width and height (default) :-2: Calculate w/h using the other dimension and the original display aspect ratio. :-3: Calculate w/h using the other dimension and the original video aspect ratio. .. admonition:: Example ``dsize=800:-2`` Specifies a display resolution of 800x600 for a 4/3 aspect video, or 800x450 for a 16/9 aspect video. ```` Modifies width and height according to original aspect ratios. :-1: Ignore original aspect ratio (default). :0: Keep display aspect ratio by using ```` and ```` as maximum resolution. :1: Keep display aspect ratio by using ```` and ```` as minimum resolution. :2: Keep video aspect ratio by using ```` and ```` as maximum resolution. :3: Keep video aspect ratio by using ```` and ```` as minimum resolution. .. admonition:: Example ``dsize=800:600:0`` Specifies a display resolution of at most 800x600, or smaller, in order to keep aspect. ```` Rounds up to make both width and height divisible by ```` (default: 1). ```` Force an aspect ratio. ``format=fmt=:colormatrix=:...`` Restricts the color space for the next filter without doing any conversion. Use together with the scale filter for a real conversion. .. note:: For a list of available formats, see ``format=fmt=help``. ```` Format name, e.g. rgb15, bgr24, 420p, etc. (default: don't change). ```` Format name that should be substituted for the output. If they do not have the same bytes per pixel and chroma subsamplimg, it will fail. ```` Controls the YUV to RGB color space conversion when playing video. There are various standards. Normally, BT.601 should be used for SD video, and BT.709 for HD video. (This is done by default.) Using incorrect color space results in slightly under or over saturated and shifted colors. These options are not always supported. Different video outputs provide varying degrees of support. The ``opengl`` and ``vdpau`` video output drivers usually offer full support. The ``xv`` output can set the color space if the system video driver supports it, but not input and output levels. The ``scale`` video filter can configure color space and input levels, but only if the output format is RGB (if the video output driver supports RGB output, you can force this with ``-vf scale,format=rgba``). If this option is set to ``auto`` (which is the default), the video's color space flag will be used. If that flag is unset, the color space will be selected automatically. This is done using a simple heuristic that attempts to distinguish SD and HD video. If the video is larger than 1279x576 pixels, BT.709 (HD) will be used; otherwise BT.601 (SD) is selected. Available color spaces are: :auto: automatic selection (default) :bt.601: ITU-R BT.601 (SD) :bt.709: ITU-R BT.709 (HD) :bt.2020-ncl: ITU-R BT.2020 non-constant luminance system :bt.2020-cl: ITU-R BT.2020 constant luminance system :smpte-240m: SMPTE-240M ```` YUV color levels used with YUV to RGB conversion. This option is only necessary when playing broken files which do not follow standard color levels or which are flagged wrong. If the video does not specify its color range, it is assumed to be limited range. The same limitations as with ```` apply. Available color ranges are: :auto: automatic selection (normally limited range) (default) :limited: limited range (16-235 for luma, 16-240 for chroma) :full: full range (0-255 for both luma and chroma) ```` RGB primaries the source file was encoded with. Normally this should be set in the file header, but when playing broken or mistagged files this can be used to override the setting. This option only affects video output drivers that perform color management, for example ``opengl`` with the ``target-prim`` or ``icc-profile`` suboptions set. If this option is set to ``auto`` (which is the default), the video's primaries flag will be used. If that flag is unset, the color space will be selected automatically, using the following heuristics: If the ```` is set or determined as BT.2020 or BT.709, the corresponding primaries are used. Otherwise, if the video height is exactly 576 (PAL), BT.601-625 is used. If it's exactly 480 or 486 (NTSC), BT.601-525 is used. If the video resolution is anything else, BT.709 is used. Available primaries are: :auto: automatic selection (default) :bt.601-525: ITU-R BT.601 (SD) 525-line systems (NTSC, SMPTE-C) :bt.601-625: ITU-R BT.601 (SD) 625-line systems (PAL, SECAM) :bt.709: ITU-R BT.709 (HD) (same primaries as sRGB) :bt.2020: ITU-R BT.2020 (UHD) :apple: Apple RGB :adobe: Adobe RGB (1998) :prophoto: ProPhoto RGB (ROMM) :cie1931: CIE 1931 RGB :dci-p3: DCI-P3 (Digital Cinema) :v-gamut: Panasonic V-Gamut primaries ```` Gamma function the source file was encoded with. Normally this should be set in the file header, but when playing broken or mistagged files this can be used to override the setting. This option only affects video output drivers that perform color management. If this option is set to ``auto`` (which is the default), the gamma will be set to BT.1886 for YCbCr content, sRGB for RGB content and Linear for XYZ content. Available gamma functions are: :auto: automatic selection (default) :bt.1886: ITU-R BT.1886 (EOTF corresponding to BT.601/BT.709/BT.2020) :srgb: IEC 61966-2-4 (sRGB) :linear: Linear light :gamma1.8: Pure power curve (gamma 1.8) :gamma2.2: Pure power curve (gamma 2.2) :gamma2.8: Pure power curve (gamma 2.8) :prophoto: ProPhoto RGB (ROMM) curve :st2084: SMPTE ST2084 (HDR) curve :std-b67: ARIB STD-B67 (Hybrid Log-gamma) curve :v-log: Panasonic V-Log transfer curve ```` Reference peak illumination for the video file. This is mostly interesting for HDR, but it can also be used tone map SDR content to a darker or brighter exposure. The default of 0.0 will default to the display's reference brightness for SDR and the source's reference brightness for HDR. ```` Set the stereo mode the video is assumed to be encoded in. Takes the same values as the ``--video-stereo-mode`` option. ```` Set the stereo mode the video should be displayed as. Takes the same values as the ``--video-stereo-mode`` option. ```` Set the rotation the video is assumed to be encoded with in degrees. The special value ``-1`` uses the input format. ````, ```` Set the display size. Note that setting the display size such that the video is scaled in both directions instead of just changing the aspect ratio is an implementation detail, and might change later. ```` Set the display aspect ratio of the video frame. This is a float, but values such as ``[16:9]`` can be passed too (``[...]`` for quoting to prevent the option parser from interpreting the ``:`` character). ``noformat[=fmt]`` Restricts the color space for the next filter without doing any conversion. Unlike the format filter, this will allow any color space except the one you specify. .. note:: For a list of available formats, see ``noformat=fmt=help``. ```` Format name, e.g. rgb15, bgr24, 420p, etc. (default: 420p). ``lavfi=graph[:sws-flags[:o=opts]]`` Filter video using FFmpeg's libavfilter. ```` The libavfilter graph string. The filter must have a single video input pad and a single video output pad. See ``_ for syntax and available filters. .. warning:: If you want to use the full filter syntax with this option, you have to quote the filter graph in order to prevent mpv's syntax and the filter graph syntax from clashing. .. admonition:: Examples ``-vf lavfi=[gradfun=20:30,vflip]`` ``gradfun`` filter with nonsense parameters, followed by a ``vflip`` filter. (This demonstrates how libavfilter takes a graph and not just a single filter.) The filter graph string is quoted with ``[`` and ``]``. This requires no additional quoting or escaping with some shells (like bash), while others (like zsh) require additional ``"`` quotes around the option string. ``'--vf=lavfi="gradfun=20:30,vflip"'`` Same as before, but uses quoting that should be safe with all shells. The outer ``'`` quotes make sure that the shell does not remove the ``"`` quotes needed by mpv. ``'--vf=lavfi=graph="gradfun=radius=30:strength=20,vflip"'`` Same as before, but uses named parameters for everything. ```` If libavfilter inserts filters for pixel format conversion, this option gives the flags which should be passed to libswscale. This option is numeric and takes a bit-wise combination of ``SWS_`` flags. See ``http://git.videolan.org/?p=ffmpeg.git;a=blob;f=libswscale/swscale.h``. ```` Set AVFilterGraph options. These should be documented by FFmpeg. .. admonition:: Example ``'--vf=lavfi=yadif:o="threads=2,thread_type=slice"'`` forces a specific threading configuration. ``eq[=gamma:contrast:brightness:saturation:rg:gg:bg:weight]`` Software equalizer that uses lookup tables (slow), allowing gamma correction in addition to simple brightness and contrast adjustment. The parameters are given as floating point values. ``<0.1-10>`` initial gamma value (default: 1.0) ``<-2-2>`` initial contrast, where negative values result in a negative image (default: 1.0) ``<-1-1>`` initial brightness (default: 0.0) ``<0-3>`` initial saturation (default: 1.0) ``<0.1-10>`` gamma value for the red component (default: 1.0) ``<0.1-10>`` gamma value for the green component (default: 1.0) ``<0.1-10>`` gamma value for the blue component (default: 1.0) ``<0-1>`` The weight parameter can be used to reduce the effect of a high gamma value on bright image areas, e.g. keep them from getting overamplified and just plain white. A value of 0.0 turns the gamma correction all the way down while 1.0 leaves it at its full strength (default: 1.0). ``pullup[=jl:jr:jt:jb:sb:mp]`` Pulldown reversal (inverse telecine) filter, capable of handling mixed hard-telecine, 24000/1001 fps progressive, and 30000/1001 fps progressive content. The ``pullup`` filter makes use of future context in making its decisions. It is stateless in the sense that it does not lock onto a pattern to follow, but it instead looks forward to the following fields in order to identify matches and rebuild progressive frames. ``jl``, ``jr``, ``jt``, and ``jb`` These options set the amount of "junk" to ignore at the left, right, top, and bottom of the image, respectively. Left/right are in units of 8 pixels, while top/bottom are in units of 2 lines. The default is 8 pixels on each side. ``sb`` (strict breaks) Setting this option to 1 will reduce the chances of ``pullup`` generating an occasional mismatched frame, but it may also cause an excessive number of frames to be dropped during high motion sequences. Conversely, setting it to -1 will make ``pullup`` match fields more easily. This may help process video with slight blurring between the fields, but may also cause interlaced frames in the output. ``mp`` (metric plane) This option may be set to ``u`` or ``v`` to use a chroma plane instead of the luma plane for doing ``pullup``'s computations. This may improve accuracy on very clean source material, but more likely will decrease accuracy, especially if there is chroma noise (rainbow effect) or any grayscale video. The main purpose of setting ``mp`` to a chroma plane is to reduce CPU load and make pullup usable in realtime on slow machines. ``yadif=[mode:interlaced-only]`` Yet another deinterlacing filter ```` :frame: Output 1 frame for each frame. :field: Output 1 frame for each field (default). :frame-nospatial: Like ``frame`` but skips spatial interlacing check. :field-nospatial: Like ``field`` but skips spatial interlacing check. ```` :no: Deinterlace all frames. :yes: Only deinterlace frames marked as interlaced (default). This filter is automatically inserted when using the ``d`` key (or any other key that toggles the ``deinterlace`` property or when using the ``--deinterlace`` switch), assuming the video output does not have native deinterlacing support. If you just want to set the default mode, put this filter and its options into ``--vf-defaults`` instead, and enable deinterlacing with ``d`` or ``--deinterlace``. Also, note that the ``d`` key is stupid enough to insert a deinterlacer twice when inserting yadif with ``--vf``, so using the above methods is recommended. ``sub=[=bottom-margin:top-margin]`` Moves subtitle rendering to an arbitrary point in the filter chain, or force subtitle rendering in the video filter as opposed to using video output OSD support. ```` Adds a black band at the bottom of the frame. The SSA/ASS renderer can place subtitles there (with ``--sub-use-margins``). ```` Black band on the top for toptitles (with ``--sub-use-margins``). .. admonition:: Examples ``--vf=sub,eq`` Moves sub rendering before the eq filter. This will put both subtitle colors and video under the influence of the video equalizer settings. ``stereo3d[=in:out]`` Stereo3d converts between different stereoscopic image formats. ```` Stereoscopic image format of input. Possible values: ``sbsl`` or ``side_by_side_left_first`` side by side parallel (left eye left, right eye right) ``sbsr`` or ``side_by_side_right_first`` side by side crosseye (right eye left, left eye right) ``abl`` or ``above_below_left_first`` above-below (left eye above, right eye below) ``abr`` or ``above_below_right_first`` above-below (right eye above, left eye below) ``ab2l`` or ``above_below_half_height_left_first`` above-below with half height resolution (left eye above, right eye below) ``ab2r`` or ``above_below_half_height_right_first`` above-below with half height resolution (right eye above, left eye below) ```` Stereoscopic image format of output. Possible values are all the input formats as well as: ``arcg`` or ``anaglyph_red_cyan_gray`` anaglyph red/cyan gray (red filter on left eye, cyan filter on right eye) ``arch`` or ``anaglyph_red_cyan_half_color`` anaglyph red/cyan half colored (red filter on left eye, cyan filter on right eye) ``arcc`` or ``anaglyph_red_cyan_color`` anaglyph red/cyan color (red filter on left eye, cyan filter on right eye) ``arcd`` or ``anaglyph_red_cyan_dubois`` anaglyph red/cyan color optimized with the least-squares projection of Dubois (red filter on left eye, cyan filter on right eye) ``agmg`` or ``anaglyph_green_magenta_gray`` anaglyph green/magenta gray (green filter on left eye, magenta filter on right eye) ``agmh`` or ``anaglyph_green_magenta_half_color`` anaglyph green/magenta half colored (green filter on left eye, magenta filter on right eye) ``agmc`` or ``anaglyph_green_magenta_color`` anaglyph green/magenta colored (green filter on left eye, magenta filter on right eye) ``aybg`` or ``anaglyph_yellow_blue_gray`` anaglyph yellow/blue gray (yellow filter on left eye, blue filter on right eye) ``aybh`` or ``anaglyph_yellow_blue_half_color`` anaglyph yellow/blue half colored (yellow filter on left eye, blue filter on right eye) ``aybc`` or ``anaglyph_yellow_blue_color`` anaglyph yellow/blue colored (yellow filter on left eye, blue filter on right eye) ``irl`` or ``interleave_rows_left_first`` Interleaved rows (left eye has top row, right eye starts on next row) ``irr`` or ``interleave_rows_right_first`` Interleaved rows (right eye has top row, left eye starts on next row) ``ml`` or ``mono_left`` mono output (left eye only) ``mr`` or ``mono_right`` mono output (right eye only) ``gradfun[=strength[:radius|:size=]]`` Fix the banding artifacts that are sometimes introduced into nearly flat regions by truncation to 8-bit color depth. Interpolates the gradients that should go where the bands are, and dithers them. ```` Maximum amount by which the filter will change any one pixel. Also the threshold for detecting nearly flat regions (default: 1.5). ```` Neighborhood to fit the gradient to. Larger radius makes for smoother gradients, but also prevents the filter from modifying pixels near detailed regions (default: disabled). ```` size of the filter in percent of the image diagonal size. This is used to calculate the final radius size (default: 1). ``dlopen=dll[:a0[:a1[:a2[:a3]]]]`` Loads an external library to filter the image. The library interface is the ``vf_dlopen`` interface specified using ``libmpcodecs/vf_dlopen.h``. .. warning:: This filter is deprecated. ``dll=`` Specify the library to load. This may require a full file system path in some cases. This argument is required. ``a0=`` Specify the first parameter to pass to the library. ``a1=`` Specify the second parameter to pass to the library. ``a2=`` Specify the third parameter to pass to the library. ``a3=`` Specify the fourth parameter to pass to the library. ``vapoursynth=file:buffered-frames:concurrent-frames`` Loads a VapourSynth filter script. This is intended for streamed processing: mpv actually provides a source filter, instead of using a native VapourSynth video source. The mpv source will answer frame requests only within a small window of frames (the size of this window is controlled with the ``buffered-frames`` parameter), and requests outside of that will return errors. As such, you can't use the full power of VapourSynth, but you can use certain filters. If you just want to play video generated by a VapourSynth (i.e. using a native VapourSynth video source), it's better to use ``vspipe`` and a FIFO to feed the video to mpv. The same applies if the filter script requires random frame access (see ``buffered-frames`` parameter). This filter is experimental. If it turns out that it works well and is used, it will be ported to libavfilter. Otherwise, it will be just removed. ``file`` Filename of the script source. Currently, this is always a python script. The variable ``video_in`` is set to the mpv video source, and it is expected that the script reads video from it. (Otherwise, mpv will decode no video, and the video packet queue will overflow, eventually leading to audio being stopped.) The script is also expected to pass through timestamps using the ``_DurationNum`` and ``_DurationDen`` frame properties. .. admonition:: Example: :: import vapoursynth as vs core = vs.get_core() core.std.AddBorders(video_in, 10, 10, 20, 20).set_output() .. warning:: The script will be reloaded on every seek. This is done to reset the filter properly on discontinuities. ``buffered-frames`` Maximum number of decoded video frames that should be buffered before the filter (default: 4). This specifies the maximum number of frames the script can request in reverse direction. E.g. if ``buffered-frames=5``, and the script just requested frame 15, it can still request frame 10, but frame 9 is not available anymore. If it requests frame 30, mpv will decode 15 more frames, and keep only frames 25-30. The actual number of buffered frames also depends on the value of the ``concurrent-frames`` option. Currently, both option values are multiplied to get the final buffer size. (Normally, VapourSynth source filters must provide random access, but mpv was made for playback, and does not provide frame-exact random access. The way this video filter works is a compromise to make simple filters work anyway.) ``concurrent-frames`` Number of frames that should be requested in parallel. The level of concurrency depends on the filter and how quickly mpv can decode video to feed the filter. This value should probably be proportional to the number of cores on your machine. Most time, making it higher than the number of cores can actually make it slower. By default, this uses the special value ``auto``, which sets the option to the number of detected logical CPU cores. The following variables are defined by mpv: ``video_in`` The mpv video source as vapoursynth clip. Note that this has no length set, which confuses many filters. Using ``Trim`` on the clip with a high dummy length can turn it into a finite clip. ``video_in_dw``, ``video_in_dh`` Display size of the video. Can be different from video size if the video does not use square pixels (e.g. DVD). ``container_fps`` FPS value as reported by file headers. This value can be wrong or completely broken (e.g. 0 or NaN). Even if the value is correct, if another filter changes the real FPS (by dropping or inserting frames), the value of this variable might not be useful. Note that the ``--fps`` command line option overrides this value. Useful for some filters which insist on having a FPS. ``display_fps`` Refresh rate of the current display. Note that this value can be 0. ``vapoursynth-lazy`` The same as ``vapoursynth``, but doesn't load Python scripts. Instead, a custom backend using Lua and the raw VapourSynth API is used. The syntax is completely different, and absolutely no convenience features are provided. There's no type checking either, and you can trigger crashes. .. admonition:: Example: :: video_out = invoke("morpho", "Open", {clip = video_in}) The special variable ``video_in`` is the mpv video source, while the special variable ``video_out`` is used to read video from. The 1st argument is the plugin (queried with ``getPluginByNs``), the 2nd is the filter name, and the 3rd argument is a table with the arguments. Positional arguments are not supported. The types must match exactly. Since Lua is terrible and can't distinguish integers and floats, integer arguments must be prefixed with ``i_``, in which case the prefix is removed and the argument is cast to an integer. Should the argument's name start with ``i_``, you're out of luck. Clips (VSNodeRef) are passed as light userdata, so trying to pass any other userdata type will result in hard crashes. ``vavpp`` VA-AP-API video post processing. Works with ``--vo=vaapi`` and ``--vo=opengl`` only. Currently deinterlaces. This filter is automatically inserted if deinterlacing is requested (either using the ``d`` key, by default mapped to the command ``cycle deinterlace``, or the ``--deinterlace`` option). ``deint=`` Select the deinterlacing algorithm. no Don't perform deinterlacing. first-field Show only first field (going by ``--field-dominance``). bob bob deinterlacing (default). weave, motion-adaptive, motion-compensated Advanced deinterlacing algorithms. Whether these actually work depends on the GPU hardware, the GPU drivers, driver bugs, and mpv bugs. ```` :no: Deinterlace all frames. :yes: Only deinterlace frames marked as interlaced (default). ``vdpaupp`` VDPAU video post processing. Works with ``--vo=vdpau`` and ``--vo=opengl`` only. This filter is automatically inserted if deinterlacing is requested (either using the ``d`` key, by default mapped to the command ``cycle deinterlace``, or the ``--deinterlace`` option). When enabling deinterlacing, it is always preferred over software deinterlacer filters if the ``vdpau`` VO is used, and also if ``opengl`` is used and hardware decoding was activated at least once (i.e. vdpau was loaded). ``sharpen=<-1-1>`` For positive values, apply a sharpening algorithm to the video, for negative values a blurring algorithm (default: 0). ``denoise=<0-1>`` Apply a noise reduction algorithm to the video (default: 0; no noise reduction). ``deint=`` Whether deinterlacing is enabled (default: no). If enabled, it will use the mode selected with ``deint-mode``. ``deint-mode=`` Select deinterlacing mode (default: temporal). All modes respect ``--field-dominance``. Note that there's currently a mechanism that allows the ``vdpau`` VO to change the ``deint-mode`` of auto-inserted ``vdpaupp`` filters. To avoid confusion, it's recommended not to use the ``--vo=vdpau`` suboptions related to filtering. first-field Show only first field. bob Bob deinterlacing. temporal Motion-adaptive temporal deinterlacing. May lead to A/V desync with slow video hardware and/or high resolution. temporal-spatial Motion-adaptive temporal deinterlacing with edge-guided spatial interpolation. Needs fast video hardware. ``chroma-deint`` Makes temporal deinterlacers operate both on luma and chroma (default). Use no-chroma-deint to solely use luma and speed up advanced deinterlacing. Useful with slow video memory. ``pullup`` Try to apply inverse telecine, needs motion adaptive temporal deinterlacing. ``interlaced-only=`` If ``yes`` (default), only deinterlace frames marked as interlaced. ``hqscaling=<0-9>`` 0 Use default VDPAU scaling (default). 1-9 Apply high quality VDPAU scaling (needs capable hardware). ``vdpaurb`` VDPAU video read back. Works with ``--vo=vdpau`` and ``--vo=opengl`` only. This filter will read back frames decoded by VDPAU so that other filters, which are not normally compatible with VDPAU, can be used like normal. This filter must be specified before ``vdpaupp`` in the filter chain if ``vdpaupp`` is used. ``d3d11vpp`` Direct3D 11 video post processing. Currently requires D3D11 hardware decoding for use. ``deint=`` Whether deinterlacing is enabled (default: no). ``interlaced-only=`` If ``yes`` (default), only deinterlace frames marked as interlaced. ``buffer=`` Buffer ```` frames in the filter chain. This filter is probably pretty useless, except for debugging. (Note that this won't help to smooth out latencies with decoding, because the filter will never output a frame if the buffer isn't full, except on EOF.)
