/**
* Mechanisms provided by this API
* -------------------------------
*
* This API provides general control over mpv playback. It does not give you
* direct access to individual components of the player, only the whole thing.
* It's somewhat equivalent to MPlayer's slave mode. You can send commands,
* retrieve or set playback status or settings with properties, and receive
* events.
*
* The API can be used in two ways:
* 1) Internally in mpv, to provide additional features to the command line
* player. Lua scripting uses this. (Currently there is no plugin API to
* get a client API handle in external user code. It has to be a fixed
* part of the player at compilation time.)
* 2) Using mpv as a library with mpv_create(). This basically allows embedding
* mpv in other applications.
*
* Documentation
* -------------
*
* The libmpv C API is documented directly in this header. Note that most
* actual interaction with this player is done through
* options/commands/properties, which can be accessed through this API.
* Essentially everything is done with them, including loading a file,
* retrieving playback progress, and so on.
*
* These are documented elsewhere:
* * http://mpv.io/manual/master/#options
* * http://mpv.io/manual/master/#list-of-input-commands
* * http://mpv.io/manual/master/#properties
*
* You can also look at the examples here:
* * https://github.com/mpv-player/mpv-examples/tree/master/libmpv
*
* Event loop
* ----------
*
* In general, the API user should run an event loop in order to receive events.
* This event loop should call mpv_wait_event(), which will return once a new
* mpv client API is available. It is also possible to integrate client API
* usage in other event loops (e.g. GUI toolkits) with the
* mpv_set_wakeup_callback() function, and then polling for events by calling
* mpv_wait_event() with a 0 timeout.
*
* Note that the event loop is detached from the actual player. Not calling
* mpv_wait_event() will not stop playback. It will eventually congest the
* event queue of your API handle, though.
*
* Synchronous vs. asynchronous calls
* ----------------------------------
*
* The API allows both synchronous and asynchronous calls. Synchronous calls
* have to wait until the playback core is ready, which currently can take
* an unbounded time (e.g. if network is slow or unresponsive). Asynchronous
* calls just queue operations as requests, and return the result of the
* operation as events.
*
* Asynchronous calls
* ------------------
*
* The client API includes asynchronous functions. These allow you to send
* requests instantly, and get replies as events at a later point. The
* requests are made with functions carrying the _async suffix, and replies
* are returned by mpv_wait_event() (interleaved with the normal event stream).
*
* A 64 bit userdata value is used to allow the user to associate requests
* with replies. The value is passed as reply_userdata parameter to the request
* function. The reply to the request will have the reply
* mpv_event->reply_userdata field set to the same value as the
* reply_userdata parameter of the corresponding request.
*
* This userdata value is arbitrary and is never interpreted by the API. Note
* that the userdata value 0 is also allowed, but then the client must be
* careful not accidentally interpret the mpv_event->reply_userdata if an
* event is not a reply. (For non-replies, this field is set to 0.)
*
* Asynchronous calls may be reordered in arbitrarily with other synchronous
* and asynchronous calls. If you want a guaranteed order, you need to wait
* until asynchronous calls report completion before doing the next call.
*
* See also the section "Asynchronous command details" in the manpage.
*
* Multithreading
* --------------
*
* The client API is generally fully thread-safe, unless otherwise noted.
* Currently, there is no real advantage in using more than 1 thread to access
* the client API, since everything is serialized through a single lock in the
* playback core.
*
* Basic environment requirements
* ------------------------------
*
* This documents basic requirements on the C environment. This is especially
* important if mpv is used as library with mpv_create().
*
* - The LC_NUMERIC locale category must be set to "C". If your program calls
* setlocale(), be sure not to use LC_ALL, or if you do, reset LC_NUMERIC
* to its sane default: setlocale(LC_NUMERIC, "C").
* - If a X11 based VO is used, mpv will set the xlib error handler. This error
* handler is process-wide, and there's no proper way to share it with other
* xlib users within the same process. This might confuse GUI toolkits.
* - mpv uses some other libraries that are not library-safe, such as Fribidi
* (used through libass), ALSA, FFmpeg, and possibly more.
* - The FPU precision must be set at least to double precision.
* - On Windows, mpv will call timeBeginPeriod(1).
* - On memory exhaustion, mpv will kill the process.
* - In certain cases, mpv may start sub processes (such as with the ytdl
* wrapper script).
* - Using UNIX IPC (off by default) will override the SIGPIPE signal handler,
* and set it to SIG_IGN. Some invocations of the "subprocess" command will
* also do that.
* - mpv may start sub processes, so overriding SIGCHLD, or waiting on all PIDs
* (such as calling wait()) by the parent process or any other library within
* the process must be avoided. libmpv itself only waits for its own PIDs.
* - If anything in the process registers signal handlers, they must set the
* SA_RESTART flag. Otherwise you WILL get random failures on signals.
*
* Encoding of filenames
* ---------------------
*
* mpv uses UTF-8 everywhere.
*
* On some platforms (like Linux), filenames actually do not have to be UTF-8;
* for this reason libmpv supports non-UTF-8 strings. libmpv uses what the
* kernel uses and does not recode filenames. At least on Linux, passing a
* string to libmpv is like passing a string to the fopen() function.
*
* On Windows, filenames are always UTF-8, libmpv converts between UTF-8 and
* UTF-16 when using win32 API functions. libmpv never uses or accepts
* filenames in the local 8 bit encoding. It does not use fopen() either;
* it uses _wfopen().
*
* On macOS, filenames and other strings taken/returned by libmpv can have
* inconsistent unicode normalization. This can sometimes lead to problems.
* You have to hope for the best.
*
* Also see the remarks for MPV_FORMAT_STRING.
*
* Embedding the video window
* --------------------------
*
* Using the render API (in render.h) is recommended. This API requires
* you to create and maintain an OpenGL context, to which you can render
* video using a specific API call. This API does not include keyboard or mouse
* input directly.
*
* There is an older way to embed the native mpv window into your own. You have
* to get the raw window handle, and set it as "wid" option. This works on X11,
* win32, and macOS only. It's much easier to use than the render API, but
* also has various problems.
*
* Also see client API examples and the mpv manpage. There is an extensive
* discussion here:
* https://github.com/mpv-player/mpv-examples/tree/master/libmpv#methods-of-embedding-the-video-window
*
* Compatibility
* -------------
*
* mpv development doesn't stand still, and changes to mpv internals as well as
* to its interface can cause compatibility issues to client API users.
*
* The API is versioned (see MPV_CLIENT_API_VERSION), and changes to it are
* documented in DOCS/client-api-changes.rst. The C API itself will probably
* remain compatible for a long time, but the functionality exposed by it
* could change more rapidly. For example, it's possible that options are
* renamed, or change the set of allowed values.
*
* Defensive programming should be used to potentially deal with the fact that
* options, commands, and properties could disappear, change their value range,
* or change the underlying datatypes. It might be a good idea to prefer
* MPV_FORMAT_STRING over other types to decouple your code from potential
* mpv changes.
*
* Also see: DOCS/compatibility.rst
*
* Future changes
* --------------
*
* This are the planned changes that will most likely be done on the next major
* bump of the library:
*
* - remove all symbols that are marked as deprecated
* - reassign enum numerical values to remove gaps
* - disabling all events by default

/**
* Create a new mpv instance and an associated client API handle to control

* functions.
*
* Some API functions will return MPV_ERROR_UNINITIALIZED in the uninitialized
* state. You can call mpv_set_property() (or mpv_set_property_string() and
* other variants, and before mpv 0.21.0 mpv_set_option() etc.) to set initial
* options. After this, call mpv_initialize() to start the player, and then use
* e.g. mpv_command() to start playback of a file.
*
* The point of separating handle creation and actual initialization is that
* you can configure things which can't be changed during runtime.
*
* Unlike the command line player, this will have initial settings suitable
* for embedding in applications. The following settings are different:
* - stdin/stdout/stderr and the terminal will never be accessed. This is
* equivalent to setting the --no-terminal option.
* (Technically, this also suppresses C signal handling.)
* - No config files will be loaded. This is roughly equivalent to using
* --config=no. Since libmpv 1.15, you can actually re-enable this option,
* which will make libmpv load config files during mpv_initialize(). If you
* do this, you are strongly encouraged to set the "config-dir" option too.
* (Otherwise it will load the mpv command line player's config.)
* For example:
* mpv_set_option_string(mpv, "config-dir", "/my/path"); // set config root
* mpv_set_option_string(mpv, "config", "yes"); // enable config loading
* (call mpv_initialize() _after_ this)
* - Idle mode is enabled, which means the playback core will enter idle mode
* if there are no more files to play on the internal playlist, instead of
* exiting. This is equivalent to the --idle option.
* - Disable parts of input handling.
* - Most of the different settings can be viewed with the command line player
* by running "mpv --show-profile=libmpv".
*
* All this assumes that API users want a mpv instance that is strictly
* isolated from the command line player's configuration, user settings, and
* so on. You can re-enable disabled features by setting the appropriate
* options.
*
* The mpv command line parser is not available through this API, but you can
* set individual options with mpv_set_property(). Files for playback must be

* Return a UNIX file descriptor referring to the read end of a pipe. This

* this function is very similar to mpv_set_wakeup_callback(), and provides
* a primitive mechanism to handle coordinating a foreign event loop and the
* libmpv event loop. The pipe is non-blocking. It's closed when the mpv_handle
* is destroyed. This function always returns the same value (on success).
*
* This is in fact implemented using the same underlying code as for
* mpv_set_wakeup_callback() (though they don't conflict), and it is as if each
* callback invocation writes a single 0 byte to the pipe. When the pipe
* becomes readable, the code calling poll() (or select()) on the pipe should
* read all contents of the pipe and then call mpv_wait_event(c, 0) until
* no new events are returned. The pipe contents do not matter and can just
* be discarded. There is not necessarily one byte per readable event in the
* pipe. For example, the pipes are non-blocking, and mpv won't block if the
* pipe is full. Pipes are normally limited to 4096 bytes, so if there are
* more than 4096 events, the number of readable bytes can not equal the number
* of events queued. Also, it's possible that mpv does not write to the pipe
* once it's guaranteed that the client was already signaled. See the example
* below how to do it correctly.
*
* Example:
*
* int pipefd = mpv_get_wakeup_pipe(mpv);
* if (pipefd < 0)
* error();
* while (1) {
* struct pollfd pfds[1] = {
* { .fd = pipefd, .events = POLLIN },
* };
* // Wait until there are possibly new mpv events.
* poll(pfds, 1, -1);
* if (pfds[0].revents & POLLIN) {
* // Empty the pipe. Doing this before calling mpv_wait_event()
* // ensures that no wakeups are missed. It's not so important to
* // make sure the pipe is really empty (it will just cause some
* // additional wakeups in unlikely corner cases).
* char unused[256];
* read(pipefd, unused, sizeof(unused));
* while (1) {
* mpv_event *ev = mpv_wait_event(mpv, 0);
* // If MPV_EVENT_NONE is received, the event queue is empty.
* if (ev->event_id == MPV_EVENT_NONE)
* break;
* // Process the event.
* ...
* }
* }
* }
*
* @deprecated this function will be removed in the future. If you need this
* functionality, use mpv_set_wakeup_callback(), create a pipe
* manually, and call write() on your pipe in the callback.
*
* @return A UNIX FD of the read end of the wakeup pipe, or -1 on error.
* On MS Windows/MinGW, this will always return -1.

*
* Instead of linking to any PE binary, we create function pointers for all mpv's
* exported symbols. For convenience names of entrypoints are redefined to those
* pointer, so no changes are required in cplugin source code, except of defining

* available for mpv to init with correct values during runtime, before calling
* `mpv_open_cplugin`.
