Following the discussion in #1253.
The events won't be removed for a while, though. (Or maybe never, unless
we run out of bits for the uint64_t event mask.)
This is not a real change (the events still work, and the alternative
mechanisms were established a few API revisions earlier), but for the
sake of notifying API users, update DOCS/client-api-changes.rst.
This is probably what libmpv users want; and it also improves error
reporting (or we'd have to add a way to communicate such mid-playback
failures as events).
Using magic integer values was an attempt to keep the API less verbose.
But it was probably not a good idea.
Reason 1 (restart) is not made explicit, because it is not used anymore
starting with the previous commit. For ABI compatibility, the value is
left as a hole in the enum.
This provides some helper functions and classes for C++/Qt. As the top
of qthelper.hpp says, this is built on top of the client API, and is a
mere helper provided for convenience.
Maybe this should be a separate library, but on the other hand I don't
see much of a point in that. It's also header-only, but C++ people like
such things. This makes it easier for us, because we don't need to care
about ABI compatibility.
The client API doesn't change, but bump it so that those who are using
this header can declare a proper dependency.
Allows passing native types as arguments.
Also some minor doc improvements, including giving some (natural)
improvements to mpv_free_node_contents().
Note: mpv_command_node_async() is completely untested.
Maybe using strings for log levels was a mistake (too broad and too
impractical), so I'm adding numeric log level at least for the receiver
side. This makes it easier to map mpv log levels to other logging
systems.
I'm still too stingy to add a function to set the log level by a numeric
value, though.
The numeric values are not directly mapped to the internal mpv values,
because then almost every file in mpv would have to include the client
API header.
Coalesce this into API version 1.6, since 1.6 was bumped just yesterday.
The API could return partial lines, meaning the message could stop
in the middle of a line, and the next message would have the rest of
it (or just the next part of it). This was a pain for the user, so do
the nasty task of buffering the lines ourselves.
Now only complete lines are sent. To make things even easier for the
API user, don't put multiple lines into a single event, but split them.
The terminal output code needed something similar (inserting a prefix
header on start of each line). To avoid code duplication, this commit
refactors the terminal output so that lines are split in a single
place.
Whether you consider the semantics weird or not depends on your use
case, but I suppose it's a bit confusing anyway. At this point, we keep
MPV_EVENT_PAUSE/UNPAUSE for compatibility only.
Make the "core-idle" property somewhat more useful in this context.
Commit 64b7811c tried to do the "right thing" with respect to whether
keyboard input should be enabled or not. It turns out that X11 does
something stupid by design. All modern toolkits work around this native
X11 behavior, but embedding breaks these workarounds.
The only way to handle this correctly is the XEmbed protocol. It needs
to be supported by the toolkit, and probably also some mpv support. But
Qt has inconsistent support for it. In Qt 4, a X11 specific embedding
widget was needed. Qt 5.0 doesn't support it at all. Qt 5.1 apparently
supports it via QWindow, but if it really does, I couldn't get it to
work.
So add a hack instead. The new --input-x11-keyboard option controls
whether mpv should enable keyboard input on the X11 window or not. In
the command line player, it's enabled by default, but in libmpv it's
disabled.
This hack has the same problem as all previous embedding had: move the
mouse outside of the window, and you don't get keyboard input anymore.
Likewise, mpv will steal all keyboard input from the parent application
as long as the mouse is inside of the mpv window.
Also see issue #1090.
When embedding a X window, it's hard to control whether it receives
mouse/keyboard input or not. It seems the X protocol itself makes this
hard (basically due to the outdated design mismatching with modern
toolkits), and we have to take care of these things explicitly.
Simply do this by manually querying and using the parent window event
flags.
This restores some MPlayer behavior (it doesn't add back exactly the
same code, but it's very similar).
This probably has some potential to interfere with libmpv embedding, so
bump the client API minor.
CC: @mpv-player/stable (if applied, client-api-changes.rst has to be
adjusted to include the 0.5.2 release)
This is probably nicer. The actual version number doesn't change (other
than the minor being incremented).
The "| 0UL" is to make the type unsigned long int, like it was before.
The intention is to make it obvious which mpv releases certain changes
will apply to.
Also attempt to fix RST formatting of the list. This is not very proper,
but probably good enough.
