" bilinear: bilinear texture filtering (fastest).\n"
" bicubic_fast: bicubic filter (without lookup texture).\n"
" sharpen3: unsharp masking (sharpening) with radius=3.\n"
" sharpen5: unsharp masking (sharpening) with radius=5.\n"
" lanczos2: Lanczos with radius=2 (recommended).\n"
" lanczos3: Lanczos with radius=3 (not recommended).\n"
" mitchell: Mitchell-Netravali.\n"
" Default: bilinear\n"
" lparam1=<value> / lparam2=<value>\n"
" Set parameters for configurable filters. Affects chroma scaler\n"
" as well.\n"
" Filters which use this:\n"
" mitchell: b and c params (defaults: b=1/3 c=1/3)\n"
" kaiser: (defaults: 6.33 6.33)\n"
" sharpen3: lparam1 sets sharpening strength (default: 0.5)\n"
" sharpen5: as with sharpen3\n"
" stereo=<n>\n"
" 0: normal display\n"
" 1: side-by-side to red-cyan stereo\n"
" 2: side-by-side to green-magenta stereo\n"
" 3: side-by-side to quadbuffer stereo\n"
" srgb\n"
" Enable gamma-correct scaling by working in linear light. This\n"
" makes use of sRGB textures and framebuffers.\n"
" This option forces the options 'indirect' and 'gamma'.\n"
" NOTE: For YUV colorspaces, gamma 1/0.45 is assumed. RGB input is always\n"
" assumed to be in sRGB.\n"
" pbo\n"
" Enable use of PBOs. This is faster, but can sometimes lead to\n"
" sporadic and temporary image corruption.\n"
" dither-depth=<n>\n"
" Positive non-zero values select the target bit depth.\n"
" no: Disable any dithering done by mpv.\n"

" swapinterval=<n>\n"
" Interval in displayed frames between to buffer swaps.\n"
" 1 is equivalent to enable VSYNC, 0 to disable VSYNC.\n"
" no-scale-sep\n"
" When using a separable scale filter for luma, usually two filter\n"
" passes are done. This is often faster. However, it forces\n"
" conversion to RGB in an extra pass, so it can actually be slower\n"
" if used with fast filters on small screen resolutions. Using\n"
" this options will make rendering a single operation.\n"
" Note that chroma scalers are always done as 1-pass filters.\n"
" cscale=<n>\n"
" As lscale but for chroma (2x slower with little visible effect).\n"
" Note that with some scaling filters, upscaling is always done in\n"
" RGB. If chroma is not subsampled, this option is ignored, and the\n"
" luma scaler is used instead. Setting this option is often useless.\n"
" fancy-downscaling\n"
" When using convolution based filters, extend the filter size\n"
" when downscaling. Trades quality for reduced downscaling performance.\n"
" no-npot\n"
" Force use of power-of-2 texture sizes. For debugging only.\n"
" Borders will look discolored due to filtering.\n"
" glfinish\n"
" Call glFinish() before swapping buffers\n"
" backend=<sys>\n"
" auto: auto-select (default)\n"
" cocoa: Cocoa/OSX\n"
" win: Win32/WGL\n"
" x11: X11/GLX\n"
" wayland: Wayland/EGL\n"
" indirect\n"
" Do YUV conversion and scaling as separate passes. This will\n"
" first render the video into a video-sized RGB texture, and\n"
" draw the result on screen. The luma scaler is used to scale\n"
" the RGB image when rendering to screen. The chroma scaler\n"
" is used only on YUV conversion, and only if the video uses\n"
" chroma-subsampling.\n"
" This mechanism is disabled on RGB input.\n"
" fbo-format=<fmt>\n"
" Selects the internal format of any FBO textures used.\n"
" fmt can be one of: rgb, rgba, rgb8, rgb10, rgb16, rgb16f, rgb32f\n"
" Default: rgb.\n"
" gamma\n"
" Always enable gamma control. (Disables delayed enabling.)\n"
"Color management:\n"
" icc-profile=<file>\n"
" Load an ICC profile and use it to transform linear RGB to\n"
" screen output. Needs LittleCMS2 support compiled in.\n"
" icc-cache=<file>\n"
" Store and load the 3D LUT created from the ICC profile in\n"
" this file. This can be used to speed up loading, since\n"
" LittleCMS2 can take a while to create the 3D LUT.\n"
" Note that this file will be up to ~100 MB big.\n"
" icc-intent=<value>\n"
" 0: perceptual\n"
" 1: relative colorimetric\n"

" Size of the 3D LUT generated from the ICC profile in each\n"
