 NULL isn't an allowed value.

 Warning: although the encoding is usually UTF-8, this is not always the
          case. File tags often store strings in some legacy codepage,
          and even filenames don't necessarily have to be in UTF-8 (at
          least on Linux). If you pass the strings to code that requires
          valid UTF-8, you have to sanitize it in some way.
          On Windows, filenames are always UTF-8, and libmpv converts
          between UTF-8 and UTF-16 when using win32 API functions. See
          the "Encoding of filenames" section for details.

 Example for reading:

     char *result = NULL;
     if (mpv_get_property(ctx, "property", MPV_FORMAT_STRING, &result) < 0)
         goto error;
     printf("%s\n", result);
     mpv_free(result);

 Or just use mpv_get_property_string().

 Example for writing:

     char *value = "the new value";
     // yep, you pass the address to the variable
     // (needed for symmetry with other types and mpv_get_property)
     mpv_set_property(ctx, "property", MPV_FORMAT_STRING, &value);

For reading, you usually would pass a pointer to a stack-allocated
mpv_node value to mpv, and when you're done you call
mpv_free_node_contents(&node).
You're expected not to write to the data - if you have to, copy it
first (which you have to do manually).

For writing, you construct your own mpv_node, and pass a pointer to the
API. The API will never write to your data (and copy it if needed), so
you're free to use any form of allocation or memory management you like.

Warning: when reading, always check the mpv_node.format member. For
         example, properties might change their type in future versions
         of mpv, or sometimes even during runtime.

Example for reading:

    mpv_node result;
    if (mpv_get_property(ctx, "property", MPV_FORMAT_NODE, &result) < 0)
        goto error;
    printf("format=%d\n", (int)result.format);

/** Create a new mpv instance and an associated client API handle to control
the mpv instance. This instance is in a pre-initialized state,
and needs to be initialized to be actually used with most other API
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
loaded with mpv_command() or others.

Note that you should avoid doing concurrent accesses on the uninitialized
client handle. (Whether concurrent access is definitely allowed or not has
yet to be decided.)

waits until all other clients are destroyed (i.e. all mpv_handles are

Since mpv_destroy() is called somewhere on the way, it's not safe to

 to the MPV_EVENT_SHUTDOWN event.
 If another mpv_handle already called mpv_terminate_destroy(), this call will
 not actually block. It will destroy the mpv_handle, and exit immediately,
 while other mpv_handles might still be uninitializing.

Before mpv client API version 1.29:

 this function will merely send a quit command and then call

aborts all of them.

This API function is mostly asynchronous itself. It will not wait until the

some work not done. How this is signaled depends on the specific command (for

/** Get a notification whenever the given property changes. You will receive
updates as MPV_EVENT_PROPERTY_CHANGE. Note that this is not very precise:
for some properties, it may not send updates even if the property changed.
This depends on the property, and it's a valid feature request to ask for
better update handling of a specific property. (For some properties, like
``clock``, which shows the wall clock, this mechanism doesn't make too
much sense anyway.)

Property changes are coalesced: the change events are returned only once the
event queue becomes empty (e.g. mpv_wait_event() would block or return
MPV_EVENT_NONE), and then only one event per changed property is returned.

You always get an initial change notification. This is meant to initialize
the user's state to the current value of the property.

Normally, change events are sent only if the property value changes according
to the requested format. mpv_event_property will contain the property value
as data member.

Warning: if a property is unavailable or retrieving it caused an error,
         MPV_FORMAT_NONE will be set in mpv_event_property, even if the
         format parameter was set to a different value. In this case, the
         mpv_event_property.data field is invalid.

If the property is observed with the format parameter set to MPV_FORMAT_NONE,
you get low-level notifications whether the property _may_ have changed, and
the data member in mpv_event_property will be unset. With this mode, you
will have to determine yourself whether the property really changed. On the
other hand, this mechanism can be faster and uses less resources.

Observing a property that doesn't exist is allowed. (Although it may still
cause some sporadic change events.)

Keep in mind that you will get change notifications even if you change a
property yourself. Try to avoid endless feedback loops, which could happen
if you react to the change notifications triggered by your own change.

Only the mpv_handle on which this was called will receive the property
change events, or can unobserve them.

overflow and silently discard further events. If this happens, making
asynchronous requests will fail as well (with MPV_ERROR_EVENT_QUEUE_FULL).

Only one thread is allowed to call this on the same mpv_handle at a time.
The API won't complain if more than one thread calls this, but it will cause
race conditions in the client when accessing the shared mpv_event struct.
Note that most other API functions are not restricted by this, and no API

Keep in mind that the callback will be called from foreign threads. You

soon as possible (i.e. no long blocking waits). Exiting the callback through
any other means than a normal return is forbidden (no throwing exceptions,
no longjmp() calls). You must not change any local thread state (such as
the C floating point environment).

You are not allowed to call any client API functions inside of the callback.
In particular, you should not do any processing in the callback, but wake up
another thread that does all the work. The callback is meant strictly for
notification only, and is called from arbitrary core parts of the player,
that make no considerations for reentrant API use or allowing the callee to
spend a lot of time doing other things. Keep in mind that it's also possible
that the callback is called from a thread while a mpv API function is called
(i.e. it can be reentrant).

In general, the client API expects you to call mpv_wait_event() to receive
notifications, and the wakeup callback is merely a helper utility to make
this easier in certain situations. Note that it's possible that there's
only one wakeup callback invocation for multiple events. You should call
mpv_wait_event() with no timeout until MPV_EVENT_NONE is reached, at which
point the event queue is empty.

removed if the mpv_handle it was registered with is destroyed. This also
continues the hook if it was being handled by the destroyed mpv_handle (but
this should be avoided, as it might mess up order of hook execution).

Hook handlers are ordered globally by priority and order of registration.
Handlers for the same hook with same priority are invoked in order of
registration (the handler registered first is run first). Handlers with
lower priority are run first (which seems backward).

See the "Hooks" section in the manpage to see which hooks are currently

/** Return a UNIX file descriptor referring to the read end of a pipe. This
pipe can be used to wake up a poll() based processing loop. The purpose of
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.
             ...
         }
     }
 }
