the slider on the touch bar was always updated when any of the related
properties changed their value. this is partially dependent on the
refresh rate of the video, in the case of time-pos. too many updates to
touch bar impact the render performance.
to prevent this we only update the slider when necessary, when the touch
bar or the touch bar item is visible. the touch bar items only need a
granularity of seconds without any decimals, but the time-pos property
provides a granularity with decimals. we floor those values and only
update the touch bar items when we have at least a 1 second difference.
we also check for the visibility of the touch bar and its items.
Fixes#8477
the NSSliderTouchBarItem seem to be broken in a way it can't be fixed.
it has constraints set by default that can't be removed and lead to
warnings and render performance regressions.
instead of using the preconfigured NSSliderTouchBarItem we use a custom
touch bar item (NSCustomTouchBarItem) with a slider, which essential are
the same. this way we can configure our constraints ourselves, which
aren't needed in the first place.

initialising UnsafeMutableRawPointer the way we did won't free those
pointers and we get dangling pointers. explicitly define a scope those
pointers are alive and auto freed.
this drops support for swift <4.1 and with this support for xcode <=9.2.
this was the last setup that is officially working on macOS 10.12.
our old legacy build macOS 10.12 + xcode 9.2 is replaced by macOS 10.13
+ xcode 9.4.1 with swift 4.1. the macOS 10.13 + xcode 10.1 VM is
replaced by the latest macOS 10.14 + xcode 11.3.1 VM. this is the oldest
version officially supported by Apple.
this is in preparations for the following commit.
the pointer used to initialise the respective structs is only guaranteed
to be alive within this constructor. the struct itself is used later and
the data it points to, is not guaranteed to be the same.
to fix this we define a scope that pointer is definitely valid and use
it within this scope. a helper function was added to get the pointers
for several data at once. otherwise we would need to nest
withUnsafeMutableBytes several times, which would make it hard to read.
currently we use the whole screen rectangle to calculate the window
geometry. this doesn't take the menu bar or the Dock into account.
by default use the visible screen rectangle instead. this is also a
change in behaviour, since the window can't be placed outside of this
rectangle anymore. also add an option to change to the old behaviour,
because it can still be useful in certain cases, like placing the window
directly underneath the menu bar when used a desktop background.
Fixes#8272
When mpv is in the background because it was started with
`mpv foo.mp3 &`, or the user did ctrl+z bg, and is then brought to the
foreground with fg, it buffers input until you press enter. This makes
it accept input almost immediately. Having a short interval isn't
important, since input is buffered until the next loop iteration.
Closes#8120.
Apparently mpv supports loading config files from the same directory as
the mpv.exe. This is a fallback of some sort. It used the old_home
mechanism.
I want to add a warning if old_home exists, but that would always show
the warning on win32. Obviously we don't want that.
Add a separate exe_dir entry to deal with that.
Untested, but probably works.
Mistakenly reverted as part of the default configuration directory
location switch-back in aa18a8e1cd.
Separation of the mpv executable directory from old_path is a
good change now that we warn about the old_config directory also
existing.

In the recent terminal commit, I "compressed" the read() error handling,
and messed it up. The return value could be -1 for other non-fatal
errors (such as EIO when trying to read while backgrounded), which
resulted in buf.len getting messed up.

Due to Unix being legacy garbage, it's not possible to safely detect the
ESC key on terminal. The key sequences are ambiguous. The code for the
ESC key also starts the sequences for other special keys.
Until now, you needed to hit ESC twice for it to be recognized.
Attempt to handle this better by using a timeout to detect the key. If
ESC is in the input buffer, but nothing else arrived after a timeout,
assume it's the ESC key. I think this is the method vim uses. Currently,
the timeout is set at 100ms. This is hardcoded and cannot be changed.
It's possible that this causes problems on slow ssh connections or so.
I'm not sure what exactly happens if you manage to get ESC + another
normal key into the input buffer. If it's a known sequence, it will be
matched and interpreted as such. If not, it'll probably be discarded.
remove the libmpv observer for the macOS specific options and use a
config cache + change callback for runtime changes. this is also a
preparation for new backends and generalises even more, since libmpv
functions can't and shouldn't be used in usual vo backends. for feature
parity the config cache is used.
move all backend independent code parts in their own folder and files,
to simplify adding new backends. the goal is to only extend one class
and add the backend dependent parts there. usually only the (un)init,
config and related parts need to be implemented per backend. furthermore
all needed windowing and related events are propagated and can be
overwritten. the other backend dependent part is usually the surface for
rendering, for example the opengl oder metal layer.
in the best case a new backend can be added with only a few hundred
lines.
lua/js utils.get_env_list() uses `environ' which was ANSI, thus
it broke any unicode names/values.
mpv already has an internal utf8_environ for win32, but it's used
only at the getenv(..) wrapper and not exposed in itself, and also it
has lazy initialization - on first getenv() call.
Now `environ' maps to a function which ensures initialization while
keeping it an l-value (like posix expects).
The cost of this fuglyness is that files should include osdep/io.h
(which now declares environ as extern) rather than declaring it
themselves, or else the build will break on mingw.
Make it possible to feed a string to stdin of a subprocess. Out of
laziness, it can't be an arbitrary byte string. (Would require adding an
option type that takes in a Lua byte string.)
Do not set stdin of a subprocess to fd 0 (i.e. mpv's stdin) anymore,
because it makes things more consistent. Enabling stdin didn't make too
much sense in the first place, so this behavior change seems
justifiable.
win32 support missing.
Fixes: #8003
This sets the activeCodePage property in the manifest, which forces the
ANSI code page to be UTF-8 in Windows 10 1903 and up. It shouldn't make
a difference for mpv itself, since mpv already uses the wide-char APIs
for most functions, however some of mpv's dependencies, such as Lua,
rely on the ANSI codepage. Hence this change enables support for Unicode
file names in Lua's I/O library.
Thanks @avih for finding this property.

This fixes the "run" and "subprocess" commands on Windows, including
youtube-dl support.
Unix-like FD inheritance is emulated on Windows by using an undocumented
data structure[1] that gets passed to the newly created process in
STARTUPINFO.lpReserved2. It consists of two sparse arrays listing the
HANDLE and internal CRT flags corresponding to each FD. This structure
is used and understood primarily by MSVCRT, but there are other runtimes
and frameworks that can write it, like libuv.
The code for creating asynchronous "anonymous" pipes in Windows has been
enhanced and moved into windows_utils.c. This is mainly an artifact of
an unfinished future change to support anonymous IPC clients in Windows.
Right now, it's still only used in subprocess-win.c
[1]: https://www.catch22.net/tuts/undocumented-createprocess
Add env and detach arguments. This means the command.c code must use the
"new" mp_subprocess2(). So also take this as an opportunity to clean up.
win32 support gets broken by it, because it never made the switch to the
newer function.
The new detach parameter makes the "run" command fully redundant, but I
guess we'll keep it for simplicity. But change its implementation to use
mp_subprocess2() (couldn't do this earlier, because win32).
Privately, I'm going to use the "env" argument to add a key binding that
starts a shell with a FILE environment variable set to the currently
playing file, so this is very useful to me.
Note: breaks windows, so for example youtube-dl on windows will not work
anymore. mp_subprocess2() has to be implemented. The old functions are
gone, and subprocess-win.c is not built anymore. It will probably work
on Cygwin.
Apparently mpv supports loading config files from the same directory as
the mpv.exe. This is a fallback of some sort. It used the old_home
mechanism.
I want to add a warning if old_home exists, but that would always show
the warning on win32. Obviously we don't want that.
Add a separate exe_dir entry to deal with that.
Untested, but probably works.
XDG is stupid, so change back to the standard behavior. Unfortunately,
most users will now have the XDG one, so we will still need to load
this. (This is exactly the same problem as when XDG support was
introduced, just the other way around).
This should not affect any normal users. Hopefully I tested this well
enough; my intention is not to torment miserable XDG fans; they can keep
using their config dir if they want it.
This changes behavior in two cases:
- new users (now creates ~/.mpv/ instead of ~/.config/mpv/)
- users which have both directories
The latter case will behave subtly or obviously different, not sure.
Just fix your shit.
Extend the manpage with all the messy details, as far as I could reverse
engineer them from the code.
This should make --term-title work in Windows 8.1 and below.
OSC sequences are defined in ECMA-48. The 'Change Window Title' command,
as far as I can tell, is a de-facto standard defined by xterm[1]. In
either case, this code is probably still not standards-compliant.
This also changes mp_write_console_ansi to convert to UTF-16 before
parsing control sequences, because that made it easier to pass the OSC
param to SetConsoleTitleW. I think it's also more correct to do it this
way, even though it doesn't really matter much for our limited terminal
parsing. As a side-effect of this, mp_write_console_ansi no longer
mutates its argument.

This code runs posix_spawnp() within a fork() in some cases, in order to
"disown" processes which are meant as being started detached. But
posix_spawnp() is not marked as async-signal-safe, so what we do is not
allowed. It could for example cause deadlocks, depending on
implementation and luck at runtime. Turns out posix_spawnp() is useless
crap.
Replace it with "classic" fork() to ensure correctness.
We could probably use another mechanism to start a process "disowned"
than doing a double-fork(). The only problem with "disowning" a process
is calling setsid() (which posix_spawnp() didn't support, but maybe will
in newer revisions), and removing as as parent from the child process
(the double-fork() will make PID 1 the parent). But there is no good way
to either remove us as parent, or to "reap" the PID in a way that is
safe and less of a mess than the current code. This is because
POSIX/UNIX is a miserable heap of shit. (Less shit than "alternatives"
like win32, no doubt.)
Because POSIX/UNIX is a miserable heap of shit, execvp() is also not
specified as async-signal-safe. It's funny how you can run a full
fledged HTTP server in an async-signal-safe context, but not start a
shitty damn process. Unix is really, really, really extremely bad at
this process management stuff. So we reimplement execvp() in an
async-signal-safe way.
The new code assumes that CLOEXEC is a thing. Since POSIX/UNIX is such a
heap of shit, O_CLOEXEC and FD_CLOEXEC were (probably) added at
different times, but both must be present. io.h defines them to 0 if
they don't exist, and in this case the code will error out at runtime.
Surely we could do without CLOEXEC via fallback, but I'll do that only
if at least 1 bug is reported wrt. this issue.
The idea how to report exec() failure or success is from musl. The way
as_execvpe() is also inspired by musl (for example, the list of error
codes that should make it fail is the same as in musl's code).
This fixes two issues with invalid value after 38/48:
- It was not detected correctly and ended up skipping 4 instead of 0.
- The intent was to skip 0, but it's better to skip the rest.
Behavior with valid 2/5 after 38/48 was correct and is unaffected.
This enables native and more complete escape-sequence handling instead
of our emulation. E.g. it supports 256/true colors, and more.
This should get enabled automatically on Windows 10 build 16257
(August 2017) or later.
Previously an SGR sequence was emulated correctly only if:
- It had exactly 1 or 2 numeric values (not 0).
- Only reset, bold, and foreground colors were supported.
- 256/true colors were not skipped correctly with their sub-values.
Now it supports the same as before, plus:
- 0-16 (inclusive) numeric values, e.g. \e[m now resets correctly.
- Supports also codes for background color, reverse, underline* .
- Supports also codes for default intensity/fg/bg/reverse/underline.
- 256/true colors are recognized and skipped gracefully.
* Reverse/underline seem to work only on windows 10.

zsh often sets DECCKM (i.e. Cursor Key Mode) meaning the arrow keys
send `SS3 A/B/C/D` instead of `CSI A/B/C/D`.
Add `key_entry` definitions for this alongside the existing DECCKM Reset
definitions.
Because pthread failures are virtually undebuggable (which sure is
pretty strange, given all these heavy instrumentation tools these days).
Of course it affects only files which include osdep/threads.h.
I'm departing from the usual way to add symbols with config.h and using
"#if", and defining it on the compiler command line + "#ifdef" because I
don't want to include config.h from a header (which would be necessary
in this case) to keep things slightly cleaner. Maybe this is misguided,
but still.
This would have been easier if mpv defined its own wrappers for all
thread functions. But we don't (which to be honest is probably better
than e.g. going crazy like VLC and essentially reimplementing
everything). This seems to be a good compromise. Since it's off by
default and basically a developer tool, the minor undefined behavior
(redefining reserved symbols) isn't much of an issue.
Change all OPT_* macros such that they don't define the entire m_option
initializer, and instead expand only to a part of it, which sets certain
fields. This requires changing almost every option declaration, because
they all use these macros. A declaration now always starts with
{"name", ...
followed by designated initializers only (possibly wrapped in macros).
The OPT_* macros now initialize the .offset and .type fields only,
sometimes also .priv and others.
I think this change makes the option macros less tricky. The old code
had to stuff everything into macro arguments (and attempted to allow
setting arbitrary fields by letting the user pass designated
initializers in the vararg parts). Some of this was made messy due to
C99 and C11 not allowing 0-sized varargs with ',' removal. It's also
possible that this change is pointless, other than cosmetic preferences.
Not too happy about some things. For example, the OPT_CHOICE()
indentation I applied looks a bit ugly.
Much of this change was done with regex search&replace, but some places
required manual editing. In particular, code in "obscure" areas (which I
didn't include in compilation) might be broken now.
In wayland_common.c the author of some option declarations confused the
flags parameter with the default value (though the default value was
also properly set below). I fixed this with this change.
The option code is very old and was added to MPlayer in the early 2000s,
when C99 was still new. MPlayer did not use the "bool" type anywhere,l
and the logical option equivalent to bool, the "flag" option type, used
int, with the convention that only the values 0 and 1 are allowed.
mpv may have hammered many, many additional tentacles to the option
code, but some of the basics never changed, and m_option_type_flag still
uses int. This seems a bit weird, since mpv uses bool for booleans. So
finally introduce an m_option_type_bool. To avoid duplicating too much
code, change the flag code to bool, and "reimplement" m_option_type_flag
on top of m_option_type_bool.
As a "demonstration", change the --fullscreen option to this new type.
Ideally, all options would be changed too bool, and m_option_type_flag
would be removed. But that is a lot of monotonous thankless work, so I'm
not doing it, and making it a painful years long transition.
At the same time, I'm introducing a new concept for option declarations.
Instead of OPT_BOOL(), which define the full m_option struct contents,
there's OPTF_BOOL(), which only takes the option field name itself. The
name is provided via a normal struct field initializer. Other fields
(such as flags) can be provided via designated initializers.
The advantage of this is that we don't need tons of nested vararg
macros. We also don't need to deal with 0-sized varargs being a pain
(and in fact they are not a thing in standard C99 and probably C11).
There is no need to provide a mandatory flags argument either, which is
the reason why so many OPT_ macros are used with a "0" argument. (The
flag argument seems to confuse other developers; they either don't
immediately recognize what it is, and sometimes it's supposed to be the
option's default value.)
Not having to mess with the flag argument in such option macros is also
a reason for the removal of M_OPT_RANGE etc., for the better or worse.
The only place that special-cased the _flag option type was in
command.c; change it to use something effectively very similar that
automatically includes the new _bool option type. Everything else should
be transparent to the change. The fullscreen option change should be
transparent too, as C99 bool is basically an integer type that is
clamped to 0/1 (except in Swift, Swift sucks).
this basically moves the remote command center to our mac events instead
of keeping it our Application, which is only available when started from
mpv itself. also make it independent of the NSApplication.
this also prevents a runtime crash
This is just a more convenient way to start IPC client scripts per mpv
instance.
Does not work on Windows, although it could if the subprocess and IPC
parts are implemented (and I guess .exe/.bat suffixes are required).
Also untested whether it builds on Windows. A lot of other things are
untested too, so don't complain.
The previous method for this sucked: for every launched detached
process, it started a thread, which then would leak if the launched
process didn't end before the player uninitialized. This was very racy
(although I bet the race condition wouldn't trigger in a 100 years), and
wasteful (threads aren't a cheap resource).
Implement it for POSIX directly. posix_spawn() has no direct support for
this, so we need to do it ourselves with fork(). We could probably do it
without fork(), and attempt to collect the PID in another thread. But
then we'd either have a waiting thread again, or we'd need to do an
unsafe waitpid(-1, ...) call. (POSIX process management sucks so badly,
how did they even manage this. Hopefully I'm just missing something, but
I'm not.) So now we depend on both posix_spawn() _and_ fork(), isn't it
fun?
Also call setsid(), to essentially detach the child process from the
terminal. (Otherwise it can receive various signals from the terminal,
which is probably not what you want.) posix_spawn() adds
POSIX_SPAWN_SETSID in newer POSIX releases, but we don't want to rely on
this yet.
The posix_spawnp() call is duplicated, but this is better than somehow
trying to unify the code paths.
Only somewhat tested, so enjoy the bugs.
Introduce mp_subprocess() and related definitions. This is a bit more
flexible than the old stuff. This may or may not be used for a more
complicated feature that involves starting processes, and which would
require more control.
Only port subprocess-posix.c to this API. The player still uses the
"old" API, so for win32 and dummy implementations, the new API is simply
not available, while for POSIX, the old APIs are emulated on top of the
new one. I'm hoping the win32 code can be ported as well, so the ifdefs
in subprocess.c can be dropped, and the player can (if convenient or
needed) use the new API.
this creates a default log for the last mpv run when started from the
bundle. that way one can get a log of what happened even after an issue
occurred. also add a menu entry under Help to show the current log, but
only when the bundle is used.
