With the previous series of commits, all internal usage has been
replaced by the nanosecond functions. There's not really any point in
keeping these around anymore plus there are macros for unit conversions
now so we can just axe them. It's worth noting that mpv_get_time_us()
obviously still needs to work for API reasons, but we can just divide
mp_time_ns() by 1000 to get the same thing.
There's a lot of wild 1e6, 1000, etc. lying around in the code. A macro
is much easier to read and understand at a glance. Add some helpers for
this. We don't need to convert everything now but there's some simple
things that can be done so they are included in this commit.
add support for vulkan through metal and a translation layer like
MoltenVK. also add the possibility to use different render timing modes
for testing.
i still consider this experimental atm.
there are currently some silly data-races in the stop/cont sighandler
due to the fact that the signal handler might get invoked in a different
thread.
this changes those sighandlers to a pipe-based approach similar to the
existing "quit" sighandler.
tio_orig and tio_orig_set are being touched inside of signal handler
which might be invoked from another thread - which makes this a data
race.
there's no real reason to set tio_orig inside of do_activate_getch2()
which is registered as a signal handler. just set it once, in
terminal_init(), before any signal handlers come in play.
this also allows removing the tio_orig_set variable completely.
do_deactivate_getch2() touches some global variables which *might have*
been fine if the terminal thread was the one that received the signal
but AFAIK which thread will handle the signal is not well defined.
in my case, when quitting mpv with CTRL+C the main thread receives the
signal rather than the terminal thread and touches those globals without
synchronization. caught by ThreadSanitizer.
the solution is to move the do_deactivate_getch2() call outside of the
signal handler.
Allows higher resolution sleeps than Sleep which has milliseconds
resolution. In practice Windows kernel does not really go below 0.5ms,
but we don't have to limit ourselves on API side of things and do the
best we can.
Linux and macOS already use nanosecond resolution for their sleep
functions. It was just being converted from microseconds before. Since
we have mp_time_ns now, go ahead and bump the precision here. The timer
for windows uses some timeBeginPeriod thing which I'm not sure what it
does really but whatever just convert the units to ms like they were
doing before. There's really no reason to keep the mp_sleep_us helper
around. A multiplication by 1000 is trivial and underlying OS clocks
have nanosecond precision.
On linux, several platforms poll for events over a fd. This has ms
accuracy, but mpv's timer is in ns now so lots of precision is lost. We
can use an mp_poll wrapper to use ppoll instead which takes a timespec
directly with nanosecond precision. On systems without ppoll this falls
back to old poll behavior. On wayland, we don't actually use this
because ppoll completely messes up the event loop for some unknown
reason.
Originally, this was added as purely a shim for macOS. However since we
want to do high resolution polling which is not neccesarily available on
all platforms, making this a generic wrapper for poll functions is
useful so rename it.
The timestamps when making a log file is actually dependent on
MP_START_TIME. This is a 10 microsecond offset that was added to the
timer as an offset. With the nanosecond change, this unit needs to be
converted as well so the offset is the same as before. After doing that,
we need to change the various mp_time_us calls in msg to mp_time_ns and
do the right conversion. This fixes the logs timestamps (i.e. so they
aren't negative anymore).
We've got an ungodly amount of OPT_REPLACED and OPT_REMOVED sitting
around in the code. This is harmless, but the vast majority of these are
ancient. 26f4f18c06 is the last commit
that touched the majority of these and of course that only changed how
options were declared so all of this stuff was deprecated even before
that. No use in keeping these, so just delete them all. As an aside,
there was actually a cocoa_opts but it had only a single option which
was replaced by something else and empty otherwise. So that entire thing
was just simply removed. OPT_REPLACED/OPT_REMOVED declarations that were
added in 0.35 or later were kept as is.
mpv saves cache by default nowadays, but vo_gpu is pretty spammy and
saves a bunch of files per shader. If someone is using the non-XDG
config directory, this all gets dumped directly into ~/.mpv which isn't
so nice. Save it to a sub directory called "cache" instead (or
alternatively submit to your XDG overlords). For unfortunate reasons,
macOS uses XDG_CONFIG_HOME and has the same legacy fallback mechanism,
so this applies to it too.
x11 and wayland had a lot of multimedia keys mapped that were missing
on windows.
Now the only ones they map that windows doesn't are `MP_KEY_WWW`,
`MP_KEY_ZOOMIN` and `MP_KEY_ZOOMOUT`, which apparently don't have any
equivalent ones on windows.
So far all the keypad keys except for `0` and `,` mapped to the same
MP_KEY_* independent of numlock state, even though different key codes
are received.
Now all the alternative functions map to appropriate MP_KEY_* defines,
with missing ones added.
This only existed as essentially a workaround for meson's behavior and
to maintain compatibility with the waf build. Since waf put everything
in a generated subdirectory, we had to put make a subdirectory called
"generated" in the source for meson so stuff could go to the right
place. Well now we don't need to do that anymore. Move the meson.build
files around so they go in the appropriate place in the subdirectory of
the source tree and change the paths of the headers accordingly. A
couple of important things to note.
1. mpv.com now gets made in build/player/mpv.com (necessary because of
a meson limitation)
2. The macos icon generation path is shortened to
TOOLS/osxbundle/icon.icns.inc.
If we see "C" in one of the language vars we check, don't treat it as a language tag.
Once we've checked everything, if we don't have any languages, but saw "C" anywhere, fall back on "en".
4502522a7a implemented cache directories
but only on linux which meant other OSes continued to save this stuff in
their config directory. Since we turned on cache by default, people are
getting cache files in there which is understandably causing some
confusion. Let's go ahead and implement a separate cache directory for
windows since there seems to be some established conventions for this
already. For people using the portable_path, the cache is saved in a
subdirectory within the portable_path since the idea is for that to be
completely self contained.
the reason for checking `EBADF|EINVAL` specifically is unknown. but it's
clearly not working as intended since it can cause issues like #11795.
instead of checking for "bad errors" check for known "good errors" where
we might not want to break out. this includes:
* EINTR: which can happen if read() is interrupted by some signal.
* EAGAIN: which happens if a non-blocking fd would block. `tty_in` is
_not_ non-blocking, so EAGAIN should never occur here. but it's added
just in case that changes in the future.

Closes: https://github.com/mpv-player/mpv/pull/11805
first of all, POLLERR is supposed to be ignored in `.events` and only
returned in `.revents`.
secondly select()'s exceptfds does not have a 1:1 correspondence with
POLLERR. thankfully, the only caller of this function (in terminal-unix)
never set the POLLERR flag so the errorfds were unused anyways.
so go ahead and remove it entirely instead of pretending we can emulate
something that's not possible.
This adds cache as a possible path for mpv to internally pick
(~/.cache/mpv for non-darwin unix-like systems, the usual config
directory for everyone else). For gpu shader cache and icc cache,
controlling whether or not to write such files is done with the new
--gpu-shader-cache and --icc-cache options respectively. Additionally,
--cache-on-disk no longer requires explicitly setting the --cache-dir
option. The old options, --cache-dir, --gpu-shader-cache-dir, and
--icc-cache-dir simply set an override for the directory to save cache
files. If unset, then the cache is saved in XDG_CACHE_HOME.
A pain point for some users is the fact that watch_later is stored in
the ~/.config directory when it's really not configuration data. Roughly
2 years ago, XDG_STATE_DIR was added to the XDG Base Directory
Specification[0] and its description, user-specific state data, actually
perfectly matches what watch_later data is for. Let's go ahead and use
this directory as the default for watch_later. This change only affects
non-darwin unix-like systems (i.e. Linux, BSDs, etc.). The directory
doesn't move for anyone else.
Internally, quite a few things change with regards to the path
selection. If the platform in question does not have a statedir concept,
then the path selection will simply return "home" instead (old
behavior). Fixes#9147.

macOS really has completely different path conventions that mpv doesn't
take into account and it treats it just like any other old unix-like
system. This means mpv enforces certain conventions on it (like all the
XDG stuff) that doesn't really apply. Since we'd like to use more of
this but at the same time not distrupt mac users even more, let's just
copy and paste the current code to a new file, update the build and call
it a day. This way, the paths of these two platforms can more freely
diverge.
c784820454 introduced a bool option type
as a replacement for the flag type, but didn't actually transition and
remove the flag type because it would have been too much mundane work.
