- --- mpv 0.25.0 ---
- 1.24   - add a MPV_ENABLE_DEPRECATED preprocessor symbol, which can be defined
-          by the user to exclude deprecated API symbols from the C headers
- --- mpv 0.23.0 ---
- 1.24   - the deprecated mpv_suspend() and mpv_resume() APIs now do nothing.
- --- mpv 0.22.0 ---
- 1.23   - deprecate setting "no-" options via mpv_set_option*(). For example,
-          instead of "no-video=" you should set "video=no".
-        - do not override the SIGPIPE signal handler anymore. This was done as
-          workaround for the FFmpeg TLS code, which has been fixed long ago.
-        - deprecate mpv_suspend() and mpv_resume(). They will be stubbed out
-          in mpv 0.23.0.
-        - make mpv_set_property() work to some degree before mpv_initialize().
-          It can now be used instead of mpv_set_option().
-        - semi-deprecate mpv_set_option()/mpv_set_option_string(). You should
-          use mpv_set_property() instead. There are some deprecated properties
-          which conflict with some options (see client.h remarks on
-          mpv_set_option()), for which mpv_set_option() might still be required.
-          In future mpv releases, the conflicting deprecated options/properties
-          will be removed, and mpv_set_option() will internally translate API
-          calls to mpv_set_property().
-        - qthelper.hpp: deprecate get_property_variant, set_property_variant,
-          set_option_variant, command_variant, and replace them with
-          get_property, set_property, command.
- --- mpv 0.19.0 ---
- 1.22   - add stream_cb API for custom protocols
- --- mpv 0.18.1 ---
- ----   - remove "status" log level from mpv_request_log_messages() docs. This
-          is 100% equivalent to "v". The behavior is still the same, thus no
-          actual API change.
- --- mpv 0.18.0 ---
- 1.21   - mpv_set_property() changes behavior with MPV_FORMAT_NODE. Before this
-          change it rejected mpv_nodes with format==MPV_FORMAT_STRING if the
-          property was not a string or did not have special mechanisms in place
-          the function failed. Now it always invokes the option string parser,
-          and mpv_node with a basic data type works exactly as if the function
-          is invoked with that type directly. This new behavior is equivalent
-          to mpv_set_option().
-          This also affects the mp.set_property_native() Lua function.
-        - generally, setting choice options/properties with "yes"/"no" options
-          can now be set as MPV_FORMAT_FLAG
-        - reading a choice property as MPV_FORMAT_NODE will now return a
-          MPV_FORMAT_FLAG value if the choice is "yes" (true) or "no" (false)
-          This implicitly affects Lua and JSON IPC interfaces as well.
-        - big changes to vo-cmdline on vo_opengl and vo_opengl_hq (but not
-          vo_opengl_cb): options are now normally not reset, but applied on top
-          of the current options. The special undocumented value "-" still
-          works, but now resets all options to before any vo-cmdline command
-          has been called.

+# 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.
+
+## List of examples
+
+### simple
+
+Very primitive terminal-only example. Shows some most basic API usage.
+
+### 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
+
+Shows how to embed the mpv video window in Qt (using normal desktop widgets).
+
+### qt_opengl
+
+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.
+
+### 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
+
+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.
+
+### sdl
+
+Show how to embed the mpv OpenGL renderer in SDL. Uses the opengl-cb API for
+video.

-Linking libmpv with MSVC programs
---------------------------------
+Additional dependencies
+=======================

-You can build C++ programs in Visual Studio and link them with libmpv. To do
-this, you need a Visual Studio which supports ``stdint.h`` (recent ones do),
-and you need to create a import library for the mpv DLL:
+pthreads
+--------
+
+mpv will use a pthreads wrapper by default. Either pthreads-win32 or
+winpthreads should work. The latter is packaged with most MinGW-w64
+environments, including MSYS2, so it shouldn't be a problem. If you don't have
+a pthreads wrapper or you want to build mpv without one, configure with:

 ```bash
-lib /def:mpv.def /name:mpv-1.dll /out:mpv.lib /MACHINE:X64
+./waf configure --enable-win32-internal-pthreads
 ```

-The string in the ``/name:`` parameter must match the filename of the DLL (this
-is simply the filename the MSVC linker will use). The ``mpv.def`` can be
-retrieved from the mpv build directory, or can be produced by MingGW's
-gendef.exe helper from the mpv DLL.
+libwaio
+-------

-Static linking is not possible.
+If you want to use ``--input-file``, you need libwaio. It's available from
+git://midipix.org/waio

-Running mpv
-----------
-
-If you want to run mpv from the MinGW-w64 shell, you will find the experience
-much more pleasant if you use the ``winpty`` utility
+To compile libwaio in MSYS2, run:

 ```bash
-pacman -S winpty
-winpty mpv.com ToS-4k-1920.mov
+git clone git://midipix.org/waio && cd waio
+
+# 32-bit build, run from mingw32_shell.bat
+./build-mingw-nt32 lib-static CC=gcc AR=ar
+cp -r include/waio /mingw32/include
+cp lib32/libwaio.a /mingw32/lib
+
+# 64-bit build, run from mingw64_shell.bat
+./build-mingw-nt64 lib-static CC=gcc AR=ar
+cp -r include/waio /mingw64/include
+cp lib64/libwaio.a /mingw64/lib
 ```
-
-If you want to move / copy ``mpv.exe`` and ``mpv.com`` to somewhere other than
-``/mingw64/bin/`` for use outside the MinGW-w64 shell, they will still depend on
-DLLs in that folder. The simplest solution is to add ``C:\msys64\mingw64\bin``
-to the windows system ``%PATH%``. Beware though that this can cause problems or
-confusion in Cygwin if that is also installed on the machine.
-
-Use of the ANGLE OpenGL backend requires a copy of the D3D compiler DLL that
-matches the version of the D3D SDK that ANGLE was built with
-(``d3dcompiler_43.dll`` in case of MinGW-built ANGLE) in the path or in the
-same folder as mpv. It must be of the same architecture (x86_64 / i686) as the
-mpv you compiled. You can find copies here:

- Changes to user interface and public API must always be approved by the

 ::

- --- mpv 0.27.0 ---
-    - drop previously deprecated --field-dominance option
-    - drop previously deprecated "osd" command
-    - remove client API compatibility handling for "script", "sub-file",
-      "audio-file", "external-file" (these cases used to log a deprecation
-      warning)
-    - drop deprecated --video-aspect-method=hybrid option choice
-    - rename --hdr-tone-mapping to --tone-mapping (and generalize it)
-    - --opengl-fbo-format changes from a choice to a string. Also, its value
-      will be checked only on renderer initialization, rather than when the
-      option is set.
-    - Using opengl-cb now always assumes 8 bit per component depth, and dithers
-      to this size. Before, it tried to figure out the depth of the first
-      framebuffer that was ever passed to the renderer. Having GL framebuffers
-      with a size larger than 8 bit per component is quite rare. If you need
-      it, set the --dither-depth option instead.
-    - --lavfi-complex can now be set during runtime. If you set this in
-      expectation it would be applied only after a reload, you might observe
-      weird behavior.
-    - add --track-auto-selection to help with scripts/applications that
-      make exclusive use of --lavfi-complex.
-    - undeprecate --loop, and map it from --loop-playlist to --loop-file (the
-      deprecation was to make sure no API user gets broken by a sudden behavior
-      change)
-    - remove previously deprecated vf_eq
-    - remove that hardware deinterlace filters (vavpp, d3d11vpp, vdpaupp)
-      changed their deinterlacing-enabled setting depending on what the
-      --deinterlace option or property was set to. Now, a filter always does
-      what its filter options and defaults imply. The --deinterlace option and
-      property strictly add/remove its own filters. For example, if you run
-      "mpv --vf=vavpp --deinterlace=yes", this will insert another, redundant
-      filter, which is probably not what you want. For toggling a deinterlace
-      filter manually, use the "vf toggle" command, and do not set the
-      deinterlace option/property. To customize the filter that will be
-      inserted automatically, use --vf-defaults. Details how this works will
-      probably change in the future.
-    - remove deinterlace=auto (this was not deprecated, but had only a very
-      obscure use that stopped working with the change above. It was also
-      prone to be confused with a feature not implemented by it: auto did _not_
-      mean that deinterlacing was enabled on demand.)
-    - add shortened mnemonic names for mouse button bindings, eg. mbtn_left
-      the old numeric names (mouse_btn0) are deprecated
-    - remove mouse_btn3_dbl and up, since they are only generated for buttons
-      0-2 (these now print an error when sent from the 'mouse' command)

-    - remove remaining deprecated audio device options, like --alsa-device
-      Some of them were removed in earlier releases.
-    - introduce --replaygain... options, which replace the same functionality
-      provided by the deprecated --af=volume:replaygain... mechanism.

-    - rename --sub-ass-style-override to --sub-ass-override, and rename the
-      `--sub-ass-override=signfs` setting to `--sub-ass-override=scale`.
-    - change default of --video-aspect-method to "bitstream". The "hybrid"

-      replacement
-    - deprecate passing multiple arguments to -add/-pre options (affects the

-    - rename --opengl-dumb-mode=no to --opengl-dumb-mode=auto, and make `no`
-      always disable it (unless forced on by hardware limitation).
-    - generalize --scale-clamp, --cscale-clamp etc. to accept a float between

-      will be kept.
-      Also, you can use libavfilter filters directly (e.g. you can use
-      --vf=name=opts instead of --vf=lavfi=[name=opts]), as long as the
-      libavfilter filter's name doesn't clash with a mpv builtin filter.
-      In the long term, --vf/--af syntax might change again, but if it does, it
-      will switch to libavfilter's native syntax. (The above mentioned direct
-      support for lavfi filters still has some differences, such as how strings
-      are escaped.) If this happens, the non-deprecated builtin filters might be
-      moved to "somewhere else" syntax-wise.
-    - deprecate --loop - after a deprecation period, it will be undeprecated,
-      but changed to alias --loop-file
-    - add --keep-open-pause=no
-    - deprecate --demuxer-max-packets
-    - change --audio-file-auto default from "exact" to "no" (mpv won't load

-      audio track anymore)
- --- mpv 0.24.0 ---
-    - deprecate --hwdec-api and replace it with --opengl-hwdec-interop.
-      The new option accepts both --hwdec values, as well as named backends.
-      A minor difference is that --hwdec-api=no (which used to be the default)
-      now actually does not preload any interop layer, while the new default
-      ("") uses the value of --hwdec.

-    - unlike in older versions, setting options at runtime will now take effect
-      immediately (see for example issue #3281). On the other hand, it will also
-      do runtime verification and reject option changes that do not work
-      (example: setting the "vf" option to a filter during playback, which fails
-      to initialize - the option value will remain at its old value). In general,
-      "set name value" should be mostly equivalent to "set options/name value"
-      in cases where the "name" property is not deprecated and "options/name"
-      exists - deviations from this are either bugs, or documented as caveats
-      in the "Inconsistencies between options and properties" manpage section.
-    - deprecate _all_ --vo and --ao suboptions. Generally, all suboptions are
-      replaced by global options, which do exactly the same. For example,
-      "--vo=opengl:scale=nearest" turns into "--scale=nearest". In some cases,
-      the global option is prefixed, e.g. "--vo=opengl:pbo" turns into

-      Most of the exact replacements are documented here:

-    - remove --vo=opengl-hq. Set --profile=opengl-hq instead. Note that this
-      profile does not force the VO. This means if you use the --vo option to
-      set another VO, it won't work. But this also means it can be used with
-      opengl-cb.
-    - remove the --vo=opengl "pre-shaders", "post-shaders" and "scale-shader"
-      sub-options: they were deprecated in favor of "user-shaders"
-    - deprecate --vo-defaults (no replacement)
-    - remove the vo-cmdline command. You can set OpenGL renderer options
-      directly via properties instead.
-    - deprecate the device/sink options on all AOs. Use --audio-device instead.
-    - deprecate "--ao=wasapi:exclusive" and "--ao=coreaudio:exclusive",
-      use --audio-exclusive instead.
-    - subtle changes in how "--no-..." options are treated mean that they are
-      not accessible under "options/..." anymore (instead, these are resolved
-      at parsing time). This does not affect options which start with "--no-",
-      but do not use the mechanism for negation options.

-    - deprecate the ao and vo auto-profiles (they never made any sense)
-    - deprecate "--vo=direct3d_shaders" - use "--vo=direct3d" instead.
-      Change "--vo=direct3d" to always use shaders by default.
-    - deprecate --playlist-pos option, renamed to --playlist-start
-    - deprecate the --chapter option, as it is redundant with --start/--end,
-      and conflicts with the semantics of the "chapter" property
-    - rename --sub-text-* to --sub-* and --ass-* to --sub-ass-* (old options
-      deprecated)
-    - incompatible change to cdda:// protocol options: the part after cdda://
-      now always sets the device, not the span or speed to be played. No
-      separating extra "/" is needed. The hidden --cdda-device options is also
-      deleted (it was redundant with the documented --cdrom-device).
-    - deprecate --vo=rpi. It will be removed in mpv 0.23.0. Its functionality

+        Handling of multichannel/surround audio changed in mpv 0.8.0 from the
+        behavior in MPlayer/mplayer2 and older versions of mpv.
+
+        The old behavior is that the player always downmixed to stereo by
+        default. The ``--audio-channels`` (or ``--channels`` before that) option
+        had to be set to get multichannel audio. Then playing stereo would
+        use the ``default`` device (which typically allows multiple programs
+        to play audio at the same time via dmix), while playing anything with
+        more channels would open one of the hardware devices, e.g. via the
+        ``surround51`` alias (typically with exclusive access). Whether the
+        player would use exclusive access or not would depend on the file
+        being played.
+
+        The new behavior since mpv 0.8.0 always enables multichannel audio,
+        i.e. ``--audio-channels=auto`` is the default. However, since ALSA
+        provides no good way to play multichannel audio in a non-exclusive
+        way (without blocking other applications from using audio), the player
+        is restricted to the capabilities of the ``default`` device by default,
+        which means it supports only stereo and mono (at least with current
+        typical ALSA configurations). But if a hardware device is selected,
+        then multichannel audio will typically work.
+
+        The short story is: if you want multichannel audio with ALSA, use
+        ``--audio-device`` to select the device (use ``--audio-device=help``

-JAVASCRIPT
-==========
-
-JavaScript support in mpv is near identical to its Lua support. Use this section
-as reference on differences and availability of APIs, but otherwise you should
-refer to the Lua documentation for API details and general scripting in mpv.
-
-Example
-------
-
-JavaScript code which leaves fullscreen mode when the player is paused:
-
-::
-
-    function on_pause_change(name, value) {
-        if (value == true)
-            mp.set_property("fullscreen", "no");
-    }
-    mp.observe_property("pause", "bool", on_pause_change);
-
-
-Similarities with Lua
---------------------
-
-mpv tries to load a script file as JavaScript if it has a ``.js`` extension, but
-otherwise, the documented Lua options, script directories, loading, etc apply to
-JavaScript files too.
-
-Script initialization and lifecycle is the same as with Lua, and most of the Lua
-functions at the modules ``mp``, ``mp.utils`` and ``mp.msg`` are available to
-JavaScript with identical APIs - including running commands, getting/setting
-properties, registering events/key-bindings/property-changes/hooks, etc.
-
-Differences from Lua
--------------------
-
-No need to load modules. ``mp``, ``mp.utils`` and ``mp.msg`` are preloaded, and
-you can use e.g. ``var cwd = mp.utils.getcwd();`` without prior setup.
-``mp.options`` is currently not implemented, but ``mp.get_opt(...)`` is.
-
-Errors are slightly different. Where the Lua APIs return ``nil`` for error,
-the JavaScript ones return ``undefined``. Where Lua returns ``something, error``
-JavaScript returns only ``something`` - and makes ``error`` available via
-``mp.last_error()``. Note that only some of the functions have this additional
-``error`` value - typically the same ones which have it in Lua.
-
-Standard APIs are preferred. For instance ``setTimeout`` and ``JSON.stringify``
-are available, but ``mp.add_timeout`` and ``mp.utils.format_json`` are not.
-
-No standard library. This means that interaction with anything outside of mpv is
-limited to the available APIs, typically via ``mp.utils``. However, some file
-functions were added, and CommonJS ``require`` is available too - where the
-loaded modules have the same privileges as normal scripts.
-
-Language features - ECMAScript 5
--------------------------------
-
-The scripting backend which mpv currently uses is MuJS - a compatible minimal
-ES5 interpreter. As such, ``String.substring`` is implemented for instance,
-while the common but non-standard ``String.substr`` is not. Please consult the
-MuJS pages on language features and platform support - http://mujs.com .
-
-Unsupported Lua APIs and their JS alternatives

-
-``Error.stack`` (string)

-
-``print`` (global)
-    A convenient alias to ``mp.msg.info``.
-
-``dump`` (global)
-    Like ``print`` but also expands objects and arrays recursively.
-
-``mp.utils.getenv(name)``
-    Returns the value of the host environment variable ``name``, or
-    ``undefined`` if the variable is not defined.
-
-``mp.utils.get_user_path(path)``
-    Expands (mpv) meta paths like ``~/x``, ``~~/y``, ``~~desktop/z`` etc.
-    ``read_file``, ``write_file`` and ``require`` already use this internaly.
-
-``mp.utils.read_file(fname [,max])``
-    Returns the content of file ``fname`` as string. If ``max`` is provided and
-    not negative, limit the read to ``max`` bytes.
-
-``mp.utils.write_file(fname, str)``
-    (Over)write file ``fname`` with text content ``str``. ``fname`` must be
-    prefixed with ``file://`` as simple protection against accidental arguments
-    switch, e.g. ``mp.utils.write_file("file://~/abc.txt", "hello world")``.
-
-Note: ``read_file`` and ``write_file`` throw on errors, allow text content only.
-
-``mp.get_time_ms()``
-    Same as ``mp.get_time()`` but in ms instead of seconds.
-
-``mp.get_script_file()``
-    Returns the file name of the current script.
-
-``exit()`` (global)
-    Make the script exit at the end of the current event loop iteration.
-    Note: please reomve added key bindings before calling ``exit()``.
-
-``mp.utils.compile_js(fname, content_str)``
-    Compiles the JS code ``content_str`` as file name ``fname`` (without loading
-    anything from the filesystem), and returns it as a function. Very similar
-    to a ``Function`` constructor, but shows at stack traces as ``fname``.
-
-Timers (global)
---------------
-
-The standard HTML/node.js timers are available:
-
-``id = setTimeout(fn [,duration [,arg1 [,arg2...]]])``
-
-``id = setTimeout(code_string [,duration])``
-
-``clearTimeout(id)``
-
-``id = setInterval(fn [,duration [,arg1 [,arg2...]]])``
-
-``id = setInterval(code_string [,duration])``
-
-``clearInterval(id)``
-
-``setTimeout`` and ``setInterval`` return id, and later call ``fn`` (or execute
-``code_string``) after ``duration`` ms. Interval also repeat every ``duration``.
-
-``duration`` has a minimum and default value of 0, ``code_string`` is
-a plain string which is evaluated as JS code, and ``[,arg1 [,arg2..]]`` are used
-as arguments (if provided) when calling back ``fn``.
-
-The ``clear...(id)`` functions cancel timer ``id``, and are irreversible.
-
-Note: timers always call back asynchronously, e.g. ``setTimeout(fn)`` will never
-call ``fn`` before returning. ``fn`` will be called either at the end of this
-event loop iteration or at a later event loop iteration. This is true also for
-intervals - which also never call back twice at the same event loop iteration.
-
-Additionally, timers are processed after the event queue is empty, so it's valid
-to use ``setTimeout(fn)`` instead of Lua's ``mp.register_idle(fn)``.
-
-CommonJS modules and ``require(id)``
------------------------------------
-
-CommonJS Modules are a standard system where scripts can export common functions
-for use by other scripts. A module is a script which adds properties (functions,
-etc) to its invisible ``exports`` object, which another script can access by
-loading it with ``require(module-id)`` - which returns that ``exports`` object.
-
-Modules and ``require`` are supported, standard compliant, and generally similar
-to node.js. However, most node.js modules won't run due to missing modules such
-as ``fs``, ``process``, etc, but some node.js modules with minimal dependencies
-do work. In general, this is for mpv modules and not a node.js replacement.
-
-A ``.js`` file extension is always added to ``id``, e.g. ``require("./foo")``
-will load the file ``./foo.js`` and return its ``exports`` object.
-
-An id is relative (to the script which ``require``'d it) if it starts with
-``./`` or ``../``. Otherwise, it's considered a "top-level id" (CommonJS term).
-
-Top level id is evaluated as absolute filesystem path if possible (e.g. ``/x/y``
-or ``~/x``). Otherwise, it's searched at ``scripts/modules.js/`` in mpv config
-dirs - in normal config search order. E.g. ``require("x")`` is searched as file
-``x.js`` at those dirs, and id ``foo/x`` is searched as file ``foo/x.js``.

-The event loop
--------------
-
-The event loop poll/dispatch mpv events as long as the queue is not empty, then
-processes the timers, then waits for the next event, and repeats this forever.
-
-You could put this code at your script to replace the built-in event loop, and
-also print every event which mpv sends to your script:
-
-::
-
-    function mp_event_loop() {
-        var wait = 0;
-        do {
-            var e = mp.wait_event(wait);
-            dump(e);  // there could be a lot of prints...

-                mp.dispatch_event(e);
-                wait = 0;
-            } else {
-                wait = mp.process_timers() / 1000;
-            }
-        } while (mp.keep_running);
-    }
-
-
-``mp_event_loop`` is a name which mpv tries to call after the script loads.
-The internal implementation is similar to this (without ``dump`` though..).
-
-``e = mp.wait_event(wait)`` returns when the next mpv event arrives, or after
-``wait`` seconds if positive and no mpv events arrived. ``wait`` value of 0
-returns immediately (with ``e.event == "none"`` if the queue is empty).
-
-``mp.dispatch_event(e)`` calls back the handlers registered for ``e.event``,
-if there are such (event handlers, property observers, script messages, etc).
-
-``mp.process_timers()`` calls back the already-added, non-canceled due timers,
-and returns the duration in ms till the next due timer (possibly 0), or -1 if
-there are no pending timers. Must not be called recursively.
-

-EMBEDDING INTO OTHER PROGRAMS (LIBMPV)
-======================================
-
-mpv can be embedded into other programs as video/audio playback backend. The
-recommended way to do so is using libmpv. See ``libmpv/client.h`` in the mpv
-source code repository. This provides a C API. Bindings for other languages
-might be available (see wiki).
-
-Since libmpv merely allows access to underlying mechanisms that can control
-mpv, further documentation is spread over a few places:
-
- https://github.com/mpv-player/mpv/blob/master/libmpv/client.h
- http://mpv.io/manual/master/#options
- http://mpv.io/manual/master/#list-of-input-commands
- http://mpv.io/manual/master/#properties
- https://github.com/mpv-player/mpv-examples/tree/master/libmpv
-
-C PLUGINS
-=========
-
-You can write C plugins for mpv. These use the libmpv API, although they do not
-use the libmpv library itself.
-
-Currently, they must be explicitly enabled at build time with
-``--enable-cplugins``. They are available on Linux/BSD platforms only.
-
-C plugins location
------------------
-
-C plugins are put into the mpv scripts directory in its config directory
-(see the `FILES`_ section for details). They must have a ``.so`` file extension.
-They can also be explicitly loaded with the ``--script`` option.
-
-API
---
-
-A C plugin must export the following function::
-
-    int mpv_open_cplugin(mpv_handle *handle)
-
-The plugin function will be called on loading time. This function does not
-return as long as your plugin is loaded (it runs in its own thread). The
-``handle`` will be deallocated as soon as the plugin function returns.
-
-The return value is interpreted as error status. A value of ``0`` is
-interpreted as success, while ``-1`` signals an error. In the latter case,
-the player prints an uninformative error message that loading failed.
-
-Return values other than ``0`` and ``-1`` are reserved, and trigger undefined
-behavior.
-
-Within the plugin function, you can call libmpv API functions. The ``handle``
-is created by ``mpv_create_client()`` (or actually an internal equivalent),
-and belongs to you. You can call ``mpv_wait_event()`` to wait for things
-happening, and so on.
-
-Note that the player might block until your plugin calls ``mpv_wait_event()``
-for the first time. This gives you a chance to install initial hooks etc.
-before playback begins.
-
-The details are quite similar to Lua scripts.
-
-Linkage to libmpv
-----------------
-
-The current implementation requires that your plugins are **not** linked against
-libmpv. What your plugins uses are not symbols from a libmpv binary, but
-symbols from the mpv host binary.

-## Preferred FFmpeg version
-
-
-Using the latest FFmpeg release (or FFmpeg git master) is strongly recommended.
-Older versions are unsupported, even if the build system still happens to
-accept them. The main reason mpv still builds with older FFmpeg versions is to
-evade arguing with people (users, distros) who insist on using older FFmpeg
-versions for no rational reason.
-
-If you want to use a stable FFmpeg release, use the latest release, which has
-most likely the best maintenance out of all stable releases. Older releases
-are for distros, and at best receive basic changes, like fixing critical security
-issues or build fixes, and at worst are completely abandoned.

-## FFmpeg ABI compatibility
-
-mpv does not support linking against FFmpeg versions it was not built with, even
-if the linked version is supposedly ABI-compatible with the version it was
-compiled against. Expect malfunctions, crashes, and security issues if you
-do it anyway.

-Newer mpv versions will refuse to start if runtime and compile time FFmpeg

 ## Relation to MPlayer and mplayer2

-mpv is a fork of MPlayer. Much has changed, and in general, mpv should be
-considered a completely new program, rather than a MPlayer drop-in replacement.

-For details see [FAQ entry](https://github.com/mpv-player/mpv/wiki/FAQ#How_is_mpv_related_to_MPlayer).
+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
-and largely unmaintained list of changes is located [here][mplayer-changes].

+
+This API function returns an array which first element is C<$elid>

+
+The generated hash contains:
+
+=for :list

+The EBML Element's name, given through C<$name>.
+= elid
+The EBML Element's hex id, given through C<$elid>. Used for lookups by L</elem_by_hexid($id)>.
+= valtype
+The EBML Element's type, given through C<$valtype>, except when C<$valtype> is an arrayref.
+= multiple
+If C<$name> ends with a C<*>, this is set as true and strips the C<*> from L</name>. Used to
+mark elements that may be repeated.
+= subelements
+An arrayref of elements that may be children of this element, given through C<$valtype> if it
+is an arrayref. Sets L</valtype> to C<sub> if there are subelements.
+= subids
+An arrayref listing all the L</elid>s of subelements, C<uniq>ified.
+
+The following elements are for mpv compatibility:
+
+=for :list
+= definename
+Name used for generating C #defines.
+= fieldname
+Name used for generating C struct fields.

+
+=head1 DESCRIPTION
+
+Represents a single Matroska element as decoded by
+L<Parse::Matroska::Reader>. This is essentially a hash
+augmented with functions for delay-loading of binary
+values and children elements.
+
+=head1 NOTE
+
+The API of this module is not yet considered stable.
+
+=attr elid
+
+The EBML Element ID, suitable for passing to
+L<Parse::Matroska::Definitions/elem_by_hexid>.
+
+=attr name
+
+The EBML Element's name.
+
+=attr type
+
+The EBML Element's type. Can be C<uint>, C<sint>,
+C<float>, C<ebml_id>, C<str> or C<binary>. See L</value>
+for details.
+
+Equivalent to
+C<elem_by_hexid($elem-E<gt>{value})-E<gt>{valtype}>.
+
+=attr value
+
+The EBML Element's value. Should be obtained through
+L</get_value>.
+
+Is an unicode string if the L</type> is C<str>, that is,
+the string has already been decoded by L<Encode/decode>.
+
+Is C<undef> if the L</type> is C<binary> and the contents
+were delay-loaded and not yet read. L</get_value> will
+do the delayed load if needed.
+
+Is an arrayref if the L</type> is C<sub>, containing
+the children nodes that were already loaded.
+
+Is a hashref if the L</type> is C<ebml_id>, containing
+the referred element's information as defined in
+L<Parse::Matroska::Definitions>. Calling
+C<elem_by_hexid($elem-E<gt>{value}-E<gt>{elid})> will
+return the same object as $elem->{value}.
+
+=attr full_len
+
+The entire length of this EBML Element, including
+the header's.
+
+=attr size_len
+
+The length of the size marker. Used when calculating
+L</full_len> from L</content_len>
+
+=attr content_len
+
+The length of the contents of this EBML Element,
+which excludes the header.
+
+=attr reader
+
+A weakened reference to the associated
+L<Parse::Matroska::Reader>.
+

+
+Returns the value contained by this EBML element.
+
+If the element has children, returns an arrayref to
+the children elements that were already encountered.
+
+If the element's type is C<binary> and the value was
+delay-loaded, does the reading now.

+If C<$recurse> is provided and is true, the method will call

+If C<$read_bin> is provided and is true, disables delay-loading
+of the contents of C<binary>-type nodes, reading the contents
+to memory.
+
+If both C<$recurse> and C<$read_bin> are true, entire EBML trees
+can be loaded without requiring seeks, thus behaving correctly
+on unseekable streams. If C<$read_bin> is false, the entire EBML
+tree is still loaded, but calling L</get_value> on C<binary>-type
