-# Client API examples
+Client API examples
+===================
 
 All these examples use the mpv client API through libmpv.
 
-## Where are the docs?
-
-The libmpv C API is documented directly in the header files (on normal Unix
-systems, this is in `/usr/include/mpv/client.h`.
-
-libmpv merely gives you access to mpv's command interface, which is documented
-here:
-* Options (`mpv_set_option()` and friends): http://mpv.io/manual/master/#options
-* Commands (`mpv_command()` and friends): http://mpv.io/manual/master/#list-of-input-commands
-* Properties (`mpv_set_property()` and friends): http://mpv.io/manual/master/#properties
-
-Essentially everything is done with them, including loading a file, retrieving
-playback progress, and so on.
-
-## Methods of embedding the video window
-
-All of these examples concentrate on how to integrate mpv's video renderers
-with your own GUI. This is generally the hardest part. libmpv enforces a
-somewhat efficient video output method, rather than e.g. returning a RGBA
-surface in memory for each frame. The latter would be prohibitively inefficient,
-because it would require conversion on the CPU. The goal is also not requiring
-the API users to reinvent their own video rendering/scaling/presentation
-mechanisms.
-
-There are currently 2 methods of embedding video.
-
-### Native window embedding
-
-This uses the platform's native method of nesting multiple windows. For example,
-Linux/X11 can nest a window from a completely different process. The nested
-window can redraw contents on its own, and receive user input if the user
-interacts with this window.
-
-libmpv lets you specify a parent window for its own video window via the `wid`
-option. Then libmpv will create its window with your window as parent, and
-render its video inside of it.
-
-This method is highly OS-dependent. Some behavior is OS-specific. There are
-problems with focusing on X11 (the ancient X11 focus policy mismatches with
-that of modern UI toolkits - it's normally worked around, but this is not
-easily possible with raw window embedding). It seems to have stability problems
-on OSX when using the Qt toolkit.
-
-### OpenGL embedding
-
-This method lets you use libmpv's OpenGL renderer directly. You create an
-OpenGL context, and then use `mpv_opengl_cb_draw()` to render the video on
-each frame.
-
-This is more complicated, because libmpv will work directly on your own OpenGL
-state. It's also not possible to have mpv automatically receive user input.
-You will have to simulate this with the `mouse`/`keypress`/`keydown`/`keyup`
-commands.
-
-You also get much more flexibility. For example, you can actually render your
-own OSD on top of the video, something that is not possible with raw window
-embedding.
-
-### Which one to use?
-
-Due to the various platform-specific behavior and problems (in particular on
-OSX), OpenGL embedding is recommended. If you're not comfortable with requiring
-OpenGL, or want to support "direct" video output such as vdpau (which might
-win when it comes to performance and energy-saving), you should probably
-support both methods if possible.

-### cocoa
+cocoa
+-----
 
 Shows how to embed the mpv video window in Objective-C/Cocoa.
 
-### cocoa-openglcb
-
-Similar to the cocoa sample, but shows how to integrate mpv's OpenGL renderer
-using libmpv's opengl-cb API. Since it does not require complicated interaction
-with Cocoa elements from different libraries, it's more robust.
-
-### qt
+qt

 Shows how to embed the mpv video window in Qt (using normal desktop widgets).
 
-### qt_opengl
+qml
+---
 
-Shows how to use mpv's OpenGL video renderer in Qt. This uses the opengl-cb API
-for video. Since it does not rely on embedding "foreign" native Windows, it's
-usually more robust, potentially faster, and it's easier to control how your
-GUI interacts with the video. You can do your own OpenGL rendering on top of
-the video as well.
+Shows how to use mpv's OpenGL video renderer in QtQuick2 with QML.
 
-### qml
-
-Shows how to use mpv's OpenGL video renderer in QtQuick2 with QML. Uses the
-opengl-cb API for video. Since the video is a normal QML element, it's trivial
-to create OSD overlays with QML-native graphical elements as well.
-
-### qml_direct
+qml_direct
+----------
 
 Alternative example, which typically avoids a FBO indirection. Might be
-slightly faster, but is less flexible and harder to use. In particular, the
-video is not a normal QML element. Uses the opengl-cb API for video.

-Introduction
-============
-
-mpv provides access to its internal via the following means:
-
-- options
-- commands
-- properties
-- events
-
-All of these are important for interfacing both with end users and API users
-(which include Lua scripts, libmpv, and the JSON IPC). As such, they constitute
-a large part of the user interface and APIs.
-
-This document lists changes to them. New changes are added to the top.
-
-Interface changes
-=================
-
-::
-
- --- mpv 0.14.0 ---
-    - vo_opengl interpolation now requires --video-sync=display-... to be set
-    - change some vo_opengl defaults (including changing tscale)
-    - add "vsync-ratio", "estimated-display-fps" properties
-    - add --rebase-start-time option
-      This is a breaking change to start time handling. Instead of making start
-      time handling an aspect of different options and properties (like
-      "time-pos" vs. "playback-time"), make it dependent on the new option. For
-      compatibility, the "time-start" property now always returns 0, so code
-      which attempted to handle rebasing manually will not break.
- --- mpv 0.13.0 ---
-    - remove VO opengl-cb frame queue suboptions (no replacement)
- --- mpv 0.12.0 ---
-    - remove --use-text-osd (useless; fontconfig isn't a requirement anymore,
-      and text rendering is also lazily initialized)
-    - some time properties (at least "playback-time", "time-pos",
-      "time-remaining", "playtime-remaining") now are unavailable if the time
-      is unknown, instead of just assuming that the internal playback position
-      is 0
-    - add --audio-fallback-to-null option
-    - replace vf_format outputlevels suboption with "video-output-levels" global
-      property/option; also remove "colormatrix-output-range" property
-    - vo_opengl: remove sharpen3/sharpen5 scale filters, add sharpen sub-option
- --- mpv 0.11.0 ---
-    - add "af-metadata" property
- --- mpv 0.10.0 ---
-    - add --video-aspect-method option
-    - add --playlist-pos option
-    - add --video-sync* options
-      "display-sync-active" property
-      "vo-missed-frame-count" property
-      "audio-speed-correction" and "video-speed-correction" properties
-    - remove --demuxer-readahead-packets and --demuxer-readahead-bytes
-      add --demuxer-max-packets and --demuxer-max-bytes
-      (the new options are not replacement and have very different semantics)
-    - change "video-aspect" property: always settable, even if no video is
-      running; always return the override - if no override is set, return
-      the video's aspect ratio
-    - remove disc-nav (DVD, BD) related properties and commands
-    - add "option-info/<name>/set-locally" property
-    - add --cache-backbuffer; change --cache-default default to 75MB
-      the new total cache size is the sum of backbuffer and the cache size
-      specified by --cache-default or --cache
-    - add ``track-list/N/audio-channels`` property
-    - change --screenshot-tag-colorspace default value
-    - add --stretch-image-subs-to-screen
-    - add "playlist/N/title" property
-    - add --video-stereo-mode=no to disable auto-conversions
-    - add --force-seekable, and change default seekability in some cases
-    - add vf yadif/vavpp/vdpaupp interlaced-only suboptions
-      Also, the option is enabled by default (Except vf_yadif, which has
-      it enabled only if it's inserted by the deinterlace property.)
-    - add --hwdec-preload
-    - add ao coreaudio exclusive suboption
-    - add ``track-list/N/forced`` property
-    - add audio-params/channel-count and ``audio-params-out/channel-count props.
-    - add af volume replaygain-fallback suboption
-    - add video-params/stereo-in property
-    - add "keypress", "keydown", and "keyup" commands
-    - deprecate --ad-spdif-dtshd and enabling passthrough via --ad
-      add --audio-spdif as replacement
-    - remove "get_property" command
-    - remove --slave-broken
-    - add vo opengl custom shader suboptions (source-shader, scale-shader,
-      pre-shaders, post-shaders)
-    - completely change how the hwdec properties work:
-        - "hwdec" now reflects the --hwdec option
-        - "hwdec-detected" does partially what the old "hwdec" property did
-          (and also, "detected-hwdec" is removed)
-        - "hwdec-active" is added
-    - add protocol-list property
-    - deprecate audio-samplerate and audio-channels properties
-      (audio-params sub-properties are the replacement)
-    - add audio-params and audio-out-params properties
-    - deprecate "audio-format" property, replaced with "audio-codec-name"
-    - deprecate --media-title, replaced with --force-media-title
-    - deprecate "length" property, replaced with "duration"
-    - change volume property:
-        - the value 100 is now always "unchanged volume" - with softvol, the
-          range is 0 to --softvol-max, without it is 0-100
-        - the minimum value of --softvol-max is raised to 100
-    - remove vo opengl npot suboption
-    - add relative seeking by percentage to "seek" command
-    - add playlist_shuffle command
-    - add --force-window=immediate
-    - add ao coreaudio change-physical-format suboption
-    - remove vo opengl icc-cache suboption, add icc-cache-dir suboption
-    - add --screenshot-directory
-    - add --screenshot-high-bit-depth
-    - add --screenshot-jpeg-source-chroma

-===============
-
-mpv has no official GUI, other than the OSC (`ON SCREEN CONTROLLER`_), which
-is not a full GUI and is not meant to be. However, to compensate for the lack
-of expected GUI behavior, mpv will in some cases start with some settings
-changed to behave slightly more like a GUI mode.
-
-Currently this happens only in the following cases:
-
-- if started using the ``mpv.desktop`` file on Linux (e.g. started from menus
-  or file associations provided by desktop environments)
-- if started from explorer.exe on Windows (technically, if it was started on
-  Windows, and all of the stdout/stderr/stdin handles are unset)
-- manually adding ``--profile=pseudo-gui`` to the command line
-
-This mode implicitly adds ``--profile=pseudo-gui`` to the command line, with
-the ``pseudo-gui`` profile being predefined with the following contents:
-
-::
-
-    [pseudo-gui]
-    terminal=no
-    force-window=yes
-    idle=once
-    screenshot-directory=~~desktop/
-
-This follows the mpv config file format. To customize pseudo-GUI mode, you can
-put your own ``pseudo-gui`` profile into your ``mpv.conf``. This profile will
-enhance the default profile, rather than overwrite it.

-        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)

-
-    ``<colorlevels>``
-        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 ``<colormatrix>`` 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)
-
-    ``<primaries>``
-        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
-        ``<colormatrix>`` 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.

-     ``<gamma>``
-        Gamma function the source file was encoded with. Normally this should be set

-        vec2 pos
-            The position to be sampled, in coordinate space [0-1].

-            eg. for subsampled content or for post-shaders.
-
-        In addition to these parameters, the following uniforms are also
-        globally available:
-
-        float random
-            A random number in the range [0-1], different per frame.
-        int frame
-            A simple count of frames rendered, increases by one per frame and
-            never resets (regardless of seeks).
-        vec2 image_size
-            The size in pixels of the input image.
-
-        For example, a shader that inverts the colors could look like this::

-        a bit more banding, but takes time to compute. Note that the strength

-        details. (Default 64)
-
-    ``deband-range=<1..64>``
-        The debanding filter's initial radius. The radius increases linearly
-        for each iteration. A higher radius will find more gradients, but
-        a lower radius will smooth more aggressively. (Default 16)

-## Overview
+mpv
+===
 
+Overview
+--------
 
 **mpv** is a media player based on MPlayer and mplayer2. It supports a wide
 variety of video file formats, audio and video codecs, and subtitle types.
 
-Releases can be found on the [release list][releases].
-
-## System requirements
-
-- A not too ancient Linux, or Windows Vista or later, or OSX 10.8 or later.
-- A somewhat capable CPU. Hardware decoding might sometimes help if the CPU
-  is too slow to decode video realtime, but must be explicitly enabled with
-  the `--hwdec` option. On Windows, a CPU with SSE4 instruction set is required
-  to get decent hardware decoding performance.
-- A not too crappy GPU. mpv is not intended to be used with bad GPUs. There are
-  many caveats with drivers or system compositors causing tearing, stutter,
-  etc. On Windows, you might want to make sure the graphics drivers are
-  current, especially OpenGL. In some cases, ancient fallback video output
-  methods can help (such as `--vo=xv` on Linux), but this use is not
-  recommended or supported.

-## Relation to MPlayer and mplayer2
-
-
-mpv is based on mplayer2, which in turn is based on the original MPlayer
-(also called mplayer, mplayer-svn, mplayer1). Many changes have been made, a
-large part of which is incompatible or completely changes how the player
-behaves. Although there are still many similarities to its ancestors, mpv
-should generally be treated as a completely different program.
-
-mpv was forked because we wanted to modernize MPlayer. This includes
-removing cruft (including features which stopped making sense 10 years ago),
-and of course adding modern features. Such huge and intrusive changes made it
-infeasible to work directly with MPlayer, which is mostly focused on
-preservation, so a fork had to be made. (Actually, mpv is based on mplayer2,
-which already started this process of removing cruft.)
-
-In general, mpv should be considered a completely new program, rather than a
-MPlayer drop-in replacement.
-
-If you are wondering what's different from mplayer2 and MPlayer, an incomplete
-list of changes is located [here][mplayer-changes].

+/* EQUALIZED KEMAR HRIR
+
+How to generate these data:
+
+1. You need the MIT Media Lab's KEMAR data, read it into an software
+   capable of signal/time series analysis (like Mathematica, Matlab,
+   ...)
+
+2. Construct an equalizing FIR inverse filter by calculating the
+   transfer function of the front, same side impulse response, then
+   take 1 over the absolute magnitude.
+
+3. Cut the poles in the inverse filter's transfer function
+   specification by limiting the amplification to 2.5 (note, this
+   number assumes that you have correct signal processing
+   normalization of the Fourier transform).
+
+4. Design the FIR inverse filter by calculating the inverse Fourier
+   transform, then chopping the coefficients down to a reasonable
+   number (N = 15 is used here), apply the Kaiser-Bessel window (alpha
+   = 2 is used here).  Note the objective is remove the color bias
+   only (as if you are using an equalizer), _not_ to do a full inverse
+   filtering. (Note: beta = pi*alpha in other notation.)
+
+   For N = 15, alpha = 2, you should get the following impulse
+   response:
+
+    0.001001558668605168,  0.00698457265741865,  0.040453643039829436,

+   -0.30297563073747436,   1.3140211791355982,  -0.30297563073747436,

+
+5. Linearly convolve all KEMAR HRIR with this inverse filter.
+
+6. Resample from 44.1 kHz sampling frequency to 48 kHz.
