when swift is disabled some headers are not included. one of them is the
options/options.h header that is needed for the vo_sub_opts struct. we
include it to fix the build without swift.
the second problem is the build time check for the macOS 10.12.2
features or more specific the Media Player support. since it is a swift
feature we can not use it when swift is disabled. add a separate
Media Player check that also depends on swift and use that new
preprocessor variable as a build time check instead.
Fixes#7282
the old event tap has several problems, like no proper priority support
or having to set accessibility permissions for mpv or the terminal.
it is now replaced by the new MediaPlayer which has proper priority
support and isn't as greedy as previously. this only includes Media Key
support and not any of the other features included in the MediaPlayer
framework, like proper Now Playing data (only set dummy data for now).
this is only available on macOS 10.12.2 and higher.
also removes some unnecessary redefines.
Fixes#6389
the Apple Remote has long been deprecated and abandoned by Apple.
current macs don't come with support for it anymore. support might be
re-added with the next commit.
using the MPContext as ta parent was a bad idea and shouldn't be done in
any circumstances there because it only supposed to be for internal
usage. this had the undesired effect that the options group was freed
but still used since the MPContext is freed afterwards.
instead manually free options group.
this removes the direct access of the mp_vo_opts stuct via the vo struct
and replaces it with the m_config_cache usage. this updates the
fullscreen and window-minimized property via m_config_cache_write_opt
instead of the old mechanism via VOCTRL and event flagging. also use the
new VOCTRL_VO_OPTS_CHANGED event for fullscreen and border changes.
I often watch sporting events. On many occasions I get files with the
same filename for each session. For example, for F1 I might have the
following directory structure:
F1/
FP1.mkv
FP2.mkv
FP3.mkv
Qualification.mkv
Race.mkv
Since usually one simply watches one race after the other, I usually
just rsync the new event's files over the old ones, so, for example,
Race.mkv will be replaced from the file for the last event with the file
from the new event.
One problem with this is that I like to use --resume-playback for other
kinds of media, so I have it on by default. That works great for, say, a
movie, but doesn't work so well with this scheme, because you can
trivially forget to pass --no-resume-playback on the command line and
end up 2 hours in, watching spoilers as the race results scroll down the
screen :-)
This patch adds a new option, --resume-playback-check-mtime, which
validates that the file's mtime hasn't changed since the watch_later
configuration was saved. It does this by setting the watch_later
configuration to have the same mtime as the file after it is saved.
Switching back and forth between checking mtime and not checking mtime
works fine, as we only choose whether to compare based on it, but we
update the watch_later configuration mtime regardless of its value.
all the get_property_* usages were removed because in some circumstances
they can lead to deadlocks. they were replaced by accessing the vo and
mp_vo_opts structs directly, like on other vos.
additionally the mpv helper was split into a mpv and libmpv helper, to
differentiate between private and public APIs and for future changes
like a macOS vulkan context for vo=gpu.
Unused now. The old stream cache used it, but it was removed.
On a side note, the demuxer cache uses mp_mkostemps(). It looks like our
Windows open() emulation handles this correctly by using CREATE_NEW, so
no functionality gets lost by the "new" approach. On the other hand, the
demuxer cache does not set FILE_FLAG_DELETE_ON_CLOSE, but instead tries
to delete the file after opening (POSIX style), which probably won't
work on Windows. But I'm not sure how to make it use the DELETE_ON_CLOSE
flag, so whatever.
If this is used, the runtime expects that wmain() instead of main() is
defined. This caused me severe problems in a certain now irrelevant
case. I think it's a good idea to avoid this special case.
We can just use main() and call GetCommandLineW() instead. This function
returns a single string, so use CommandLineToArgvW() to split it, and
hope it has the same semantics. Should this ever return NULL, hope that
it leaves argc at 0.
Untested, I think.
Supposed to follow the standard function.
The standard function is not standard, but a GNU extension. Adding some
ifdef mess is pointless too - it has no advantages other than having a
mess, and not spotting implementation bugs in the emulation due to
running it only on "obscure" platforms (like Windows, so most computers
actually, except the developer's platform).
There is mkstemp(), which at least is in POSIX 2008. But it's 100%
useless, except in some obscure cases: it doesn't set O_CLOEXEC, nor can
you pass it to it. Without O_CLOEXEC, we'd leak the temporary file to
all child processes. (The fact that the file, which is expected to reach
double or tripple digit GB sizes, will be deleted only once all
processes unreference the FD, makes this sort of a big deal. You could
ftruncate() it, but that doesn't fix all the other problems.)
Why did POSIX standardize mkstemp() and O_CLOEXEC apparently at the same
time, but provided no way to pass O_CLOEXEC to mkstemp()? With the
introduction of O_CLOEXEC, they acknowledged that there's a need to
atomically set the FD_CLOEXEC flag when creating file descriptors.
(FD_CLOEXEC was standard before that, but setting it with fcntl() is
racy.) You're much more likely to need a temp file that is CLOEXEC
rather than the opposite, and even if they were somehow opposed to
CLOEXEC by default (such as for compat. reasons), surely POSIX could
have standardized mkostemp() too or instead.
And then there's the fact that this whole O_CLOEXEC mess is stupid.
Surely there would have been a better way to handle this, instead of
requiring adding O_CLOEXEC to almost ALL instances of open() in all code
that has been written ever. The justification for this is that the
historic default was wrong, and you can't change it (e.g. this won't
work: changing the behavior of exec() and not inherit the FD to the
child process, unless a hypothetical O_KEEP_EXEC flag is set).
But on the other hand, surely you could have introduced an exec()
variant which does close all FDs, except a whitelist of FDs passed to
it. Let's call it execve2(). In fact, I'm going to argue that exec()
call sites are the most aware of whether (and which) FDs to inherit.
Some programs even tried to explicitly iterate over all opened FDs and
explicitly close "unwanted" FDs (which of course was problematic for
other reasons), and such an execve2() call would have been the ideal
solution.
Maybe this proposed solution would have had problems too. But surely
revisiting and reviewing every exec*() call would have been simpler than
reviewing every open() call. And more importantly, having to extend
every damn library function that either calls open() or creates FDs in
some other way, like mkstemp().
What argument are there going to be against this? That there will be
library code that can't keep working correctly with processes that use
the "old" exec? Well, what about all my legacy library code that uses
open() incorrectly, and that will break no matter what?
Well, I'm not going to claim that I can come up with better solutions
than POSIX (generally or in this case), but this situation is ABSOLUTELY
ATROCIOUS. It makes win32 programming look attractive compared to POSIX,
that standard pandering to dead people from the past. (Note: not trying
to insult dead people.)
I'm not sure what POSIX is even doing. Anything useful? Doesn't look
like it to me. Are they paid? Why? They didn't even fix the locale mess,
nor do they intend to. I bet they're proud of discussing compatibility
to 70ies code day in and day out iwtohut ever producing anything useful.
What a load of crap. They seriously got to do better than this.
Oh, and my wrapper is probably buggy. Fortunately that doesn't matter.
Also I'm dumping this into io.h. Originally, io.h was just supposed to
replace broken implementation of standard functions by MinGW (and then
by Android), but whatever, just give a dumping ground for shit code.
this migrates our current swift code to version 5 and 4. building is
support from 10.12.6 and xcode 9.1 onwards.
dynamic linking is the new default, since Apple removed static libs
from their new toolchains and it's the recommended way.
additionally the found macOS SDK version is printed since it's an
important information for finding possible errors now.
Fixes#6470
the force unwrapping of optionals caused many unpredictable segfaults
instead of gracefully exiting or falling back. besides that, it is bad
practice and the code is a lot more stable now.
half of the materials we used were deprecated with macOS 10.14, broken
and not supported by run time changes of the macOS theme. furthermore
our styling names were completely inconsistent with the actually look
since macOS 10.14, eg ultradark got a lot brighter and couldn't be
considered ultradark anymore.
i decided to drop the old option --macos-title-bar-style and rework
the whole mechanism to allow more freedom. now materials and appearance
can be set separately. even if apple changes the look or semantics in
the future the new options can be easily adapted.
new events were added but not fetched by the vo, because we didn't
signal the vo that new events were available.
actually wakeup the vo when new events are available.
Manual changes done:
* Merged the interface-changes under the already master'd changes.
* Moved the hwdec-related option changes to video/decode/vd_lavc.c.
this adds support for GPU rendered screenshots, DR (theoretically) and
possible other advanced functions in the future that need to be executed
from the rendering thread.
additionally frames that would be off screen or not be displayed when on
screen are being dropped now.
without assistive-device permissions the event tap can't be create on
10.14 any more which lead to an assertion.

add mpv or your terminal App to the list.
by default the pixel format creation falls back to software renderer
when everything fails. this is mostly needed for VMs. additionally one
can directly request an sw renderer or exclude it entirely.
moved the retrieval of the macOS specific options from the backend
initialisation to the initialisation of the CocoaCB class, the earliest
point possible. this way macOS specific options can be used for the
opengl context creation for example.
the pre-allocation was needed because the layer allocated a opengl
context async itself and we couldn't influence that. so we had to start
the core after the context was actually allocated. furthermore a window,
view and layer hierarchy had to be created so the layer would create
a context.
now, instead of relying on the layer to create a context we do this
manually and re-use that context later when the layer wants to create
one async itself.
Avoids 100% CPU usage due to terminal code retrying read(). Seems like
this was "forgotten" (or there was somehow the assumption poll() would
not signal POLLIN anymore).
Fixes#5842.

It seems a bit inappropriate to have dumped this into stream.c, even if
it's roughly speaking its main user. At least it made its way somewhat
unfortunately to other components not related to the stream or demuxer
layer at all.
I'm too greedy to give this weird helper its own file, so dump it into
thread_tools.c.
Probably a somewhat pointless change.
This makes ICY title changes show up at approximately the correct time,
even if the demuxer buffer is huge. (It'll still be wrong if the stream
byte cache contains a meaningful amount of data.)
It should have the same effect for mid-stream metadata changes in e.g.
OGG (untested).
This is still somewhat fishy, but in parts due to ICY being fishy, and
FFmpeg's metadata change API being somewhat fishy. For example, what
happens if you seek? With FFmpeg AVFMT_EVENT_FLAG_METADATA_UPDATED and
AVSTREAM_EVENT_FLAG_METADATA_UPDATED we hope that FFmpeg will correctly
restore the correct metadata when the first packet is returned.
If you seke with ICY, we're out of luck, and some audio will be
associated with the wrong tag until we get a new title through ICY
metadata update at an essentially random point (it's mostly inherent to
ICY). Then the tags will switch back and forth, and this behavior will
stick with the data stored in the demuxer cache. Fortunately, this can
happen only if the HTTP stream is actually seekable, which it usually is
not for ICY things. Seeking doesn't even make sense with ICY, since you
can't know the exact metadata location. Basically ICY metsdata sucks.
Some complexity is due to a microoptimization: I didn't want additional
atomic accesses for each packet if no timed metadata is used. (It
probably doesn't matter at all.)
the icc profile data is mutated to an UnsafeMutablePointer and could
possibly changed. therefore the size of it should be accessed before a
possible change.
commit 2edf00f changed the MPV_EVENT_SHUTDOWN behaviour slightly, such
that it will only be sent once. cocoa-cb relied on it being sent
continuously till all mpv_handles are destroyed. now it manually shuts
down and destroys the mpv_handle after the animation instead of relying
on this removed behaviour.
when we transitioned to the new libmpv API with commit ae29725 i
reintroduced an old bug that was fixed with 7f714c6 because of a dumb
rebasing error on my part. the branch i based the libmpv changed on was
originally without the fbo fix and on rebasing i forgot to change the
variable to the proper one, basically deactivating the fix.
