POSIX permits select() to modify the timeout, which can happen on the
Linux implementation. This can reset the timeout, which spins this into
a tight loop. A timeout isn't necessary in the first place, so just use
NULL instead.
stdatomic.h defines no atomic_float typedef. We can't just use _Atomic
unconditionally, because we support compilers without C11 atomics. So
just create a custom atomic_float typedef in the wrapper, which uses
_Atomic in the C11 code path.
This sliences some warnings about unused values and statements with no
effect, but it also fixes a logic error with freelocale(), since
previously it would not work as expected when used in the body of an if
statement without braces.
Uses real functions, because with macros, I don't think there is a way
to silence the "statement with no effect" warnings in the case where the
return value of uselocale() is ignored.
As for replacing the these functions with working implementations, I
don't think this is possible for mpv's use-case, since MSVCRT does not
support UTF-8 locales, or any locale with multibyte characters that are
three or more bytes long. See:
https://docs.microsoft.com/en-us/cpp/c-runtime-library/reference/setlocale-wsetlocale
Directory-opening never worked on Windows because MSVCRT's open()
doesn't open directories and its fstat() doesn't recognise directory
handles. These are just MSVCRT restrictions, and the Windows API itself
has no problem with opening directories as file objects, so reimplement
mpv's mp_open and mp_stat to use the Windows API directly. This should
fix directory playback.
This also populates the st_dev and st_ino fields of struct stat, so
filesystem loop checking in demux_playlist.c should now work on Windows.
Fixes#4711
with the previous commit we removed the ability of loading the standard
shell environment. this exact behaviour can only be re-added by either
invoking the standard shell in a background process and reading it's
environment vars or by manually reading all the various shell configs.
both ways are kinda dirty and the former was already rejected before.
for now we will just add some commonly used paths, when started from the
bundle, so it can find the binaries used by mpv again. for example the
youtube-dl one for our youtube-dl hook.
Apple slightly changed the App bundle mechanism which broke wrapper
scripts that invoke the actual binary. it caused the bundle to always
open a new instance of mpv instead of reusing the currently running one.
just removing the wrapper script would lead to several regressions, so
it was replaced with a symlink to the bundle binary. detection if mpv
was started from the bundle was replaced by comparing the execution name
of the binary, eg the name of the symlink "mpv-bundle". additionally,
because we load a standard config from the Resources folder of the
bundle again, we prevent that config from being loaded if mpv wasn't
started via the bundle. the psn argument has to be removed manually
again.
the ability of loading your standard shell environment has been removed
with the wrapper. a substitution will be added with another commit. as a
side effect this fixes an issues when zsh was used with common NodeJS
configuration scripts.
Fixes#4926#4866
This fixes >2GiB files with at least API level 21.

for the gritty details.
* Based on libavformat's things, except we do not care about API
versions or NDKs without unistd.h, which contains all sorts of
things that we utilize.
* Redefines lseek to always point to the 64bit version.
* Redefines fseeko to always point towards an inlined static
implementation that utilizes the 64bit version of lseek underneath.
other Apps do the same as mpv and tap into the global event chain.
events that are handled are not being propagated down the event chain.
that can lead to mpv not getting any media key events anymore when they
are held back by other Apps. we will just move mpv back to the top of
the event list when mpv is refocused and is not at the top of the list
any more.
Fixes#4834
98f5579 added a safeguard for the deactivation of the automatic tab bar
but it still needs a compile time guard. add a forward declaration for
the setAllowsAutomaticWindowTabbing method of NSWindow.
Fixes#4783
As pointed out by uau on IRC, the pointer to info is still used outside
of the lock. An extremely small race condition window, but still a race
condition.
The struct m_thread_info pointer is part of an array, that will be
reallocated if another thread is created while the run_thread is just
being called. In previous versions of this code, the pointer was stable
(as long as the thread existed), so this was overlooked.
Fixes#4770. I'm not sure why this triggers it so reliably, while it
remained undetected otherwise.
This currently is only limited to Android. Its stdlib contains the
things that mpv's POSIX check checks for, but unfortunately not
glob().
This fixes Android compilation broken in 70a70b9da .
This was attempted before in fc9695e63b, but it was reverted in
1b7ce759b1 because it caused conflicts with other software watching
the same keys (See #2041.) It seems like some PCs ship with OEM software
that watches the volume keys without consuming key events and this
causes them to be handled twice, once by mpv and once by the other
software.
In order to prevent conflicts like this, use the WM_APPCOMMAND message
to handle media keys. Returning TRUE from the WM_APPCOMMAND handler
should indicate to the operating system that we consumed the key event
and it should not be propogated to the shell. Also, we now only listen
for keys that are directly related to multimedia playback (eg. the
APPCOMMAND_MEDIA_* keys.) Keys like APPCOMMAND_VOLUME_* are ignored, so
they can be handled by the shell, or by other mixer software.
The count parameter refers to the number of wide-characters to write to
the buffer (including the terminating NUL character, which is always
added,) not the number of bytes. See C99 7.24.2.3 or
https://msdn.microsoft.com/en-us/library/ybk95axf.aspx
While this is perfectly OK on Unix, it causes annoying valgrind
warnings, and might be otherwise confusing to others.
On Windows, the runtime can actually abort the process if this is
called.
push.c part taken from a patch by Pedro Pombeiro.
In a bunch of cases, we emulate highly platform specific APIs on a
higher level across all OSes, such as IPC, terminal, subprocess
handling, and more. We have source files for each OS, and they implement
all the same mpv internal API.
Selecting which source file to use on an OS can be tricky, because there
is partially overlapping and emulated APIs (consider Cygwin on Windows).
Add a pick_first_matching_dep() function to make this slightly easier
and more structured.
Also add dummy backends in some cases, to deal with APIs not being
available.
Clarify the Windows dependency identifiers, as these are the most
confusing.
This reverts commit 2e81698d28.
Seems like this was a patch applied from someone who can't agree to LGPL
relicensing (see previous commit), with the author field not properly
set.
This is not so important anyway, so just revert it.
Don't use __thread, which requires heavy runtime in some cases (such as
MinGW-w64, at least under some configurations, forcing you to link to
its pthread runtime DLL).
The pthread_t struct was needed over a simple thread ID, because
pthread_join() needed to access some sort of context from pthread_t.
Further, pthread_exit() and pthread_detach() need the context of the
current thread, for which we relied on TLS.
Replace these uses by a global thread array. This includes all threads
created by the thread wrapper. Hopefully the number of threads created
by mpv is low (say, below 20), and threads are not that often created or
destroyed. So just keeping them in an array with linear search lookup
should be reasonable.
All authors of the current code have agreed.
The code probably originates from a software named GySmail (as the
copyright header indicates). As far as I can tell, it was written by
Arpi (who has agreed), possibly with unknown co-authors. This is most
likely OK, as none of the original code is around anymore anyway. I
could not find a working download of GySmail, that actually contained
the original getch2.c code.
This also has a wild history of random people adding ifdef guards to
control ioctl() vs. tcgetattr() calls. (See for example 2b1310abba4c1.)
Later, the ioctl() was removed in favor of the POSIX tcgetattr(), and
the ifdeffery was removed. So these people were not contacted.
All authors have agreed.
mpv.exe.manifest probably can't have a copyright header, so it doesn't.
These files don't add license info to the executables. And of course the
executable license is still GPL.
Windows, as of the Creators Update, finally has a sane API for giving a
name to a thread that can be used by debuggers. This is similar to
pthread_setname_np on Linux and some Unixes. Expose it in the pthread
wrapper and use it for mpthread_set_name().
This didn't have a header and this was implied LGPL, but this was not
entirely correct. It turns out the printf attribute code was leaked in
from talloc, which is "LGPL v3 or later". talloc was added to the
mplayer2 code base in 27a30e310e. This remaining code was an oversight.
Since we want to reduce LGPL v3 code, replace this code with the one
from ta/ta.h. This code was explicitly written newly to get rid of
talloc and its license in 0933f12d28.
All authors have agreed, with the following exceptions:
e68d7f6858: wight wasn't asked (I think...), but even if he modified the
patch he applied, all code added by it was removed again later.
cb7768f9bb: nick could not be reached, but the declarations he added as
well as the full timer.c file were deleted again in cff81fe498 and
f800a42e45 (did it really take 6 years to remove unused declarations?).
ffaf4af230: it looks like this person wasn't contacted, but the code
added was removed again in f544bcf105.
There is explicit code to handle the libmpv case, but it expects that
a dispatch queue is running. This is not necessarily the case. E.g.
edit the simple.c mpv example not to do any playback and to destroy
the mpv handle immediately. It will freeze on exit, because nothing
will release the mpv_handle.
I'm not sure how this should be fixed, so disable it for now in
library mode.
The license text refers a "above copyright notice", so I guess it'd be
good to actually provide such a notice.
Add the license to some files that were missing it (since in theory, our
Copyright file says that such files are LGPL by default).
Remove the questionable remarks about the license in the client API.
when building with a deployment target older than an SDK with Touch Bar
support we still tried to access the TouchBar, since the compile time
checks are positive. to prevent this we add two runtime checks.
a small logic error in 063ca8f broke the filtering of the menu bar item
key shortcuts. they where called several times per event because the
propagation wasn't stopped properly.
for a reason i can just assume some key events can vanish from the
event chain and mpv seems unresponsive.
after quite some testing i could confirm that the events are present at
the first entry point of the event chain, the sendEvent method of the
Application, and that they vanish at a point afterwards. now we use
that entry point to grab keyDown and keyUp events. we also stop
propagating those key events to prevent the no key input' error sound.
if we ever need the key events somewhere down the event chain we need
to start propagating them again. though this is not necessary currently.
