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.
Most of the DVB test fragment was added in 2e399f39 by someone who
wasn't asked for LGPL relicensing permission. Thus remove it. (For some
weird reason, the configure check wasn't even for the later added actual
DVB code.)
Since DVB is disabled by default, this isn't too bad. But if someone
enables it, and the system doesn't support it, he will receive a weird
compilation error. That has to be good enough, until maybe someone adds
a new check.
The user bugmen0t was apparently a shared github account with publicly
available login. Thus, we can't get LGPL relicensing permission from the
people who used this account. To relicense successfully, we have to
remove all their changes.
This commit should remove 20d1fc13, f26fb009, defbe48d. It also should
remove whatever test fragments were copied from the ancient configure,
as well as some configure logic (potentially that device path stuff).
I think this change still preserves the most important use-cases of OSS:
BSDs, and the Linux OSS emulation (the latter for testing only).
According to an OSS user, the 4front checks were probably broken anyway.
The SunAudio stuff was probably for (Open)Solaris, which is dead.
ao_oss.c itself will remain GPL, and still contains bugmen0t changes.
Most contributors have agreed. This claims it's based on gstreamer code,
but this was LGPL at the time (and still is). Contributors whose code
was removed were not accounted for. There are still some potentially
problematic cases:
06eee1b67 is potentially the most problematic case. Most of these
changes are gone due to mpv not using BITMAPINFOHEADER anymore. Some
of the other changes are rather trivial. If someone contests this and
claims that copyrightable changes are left, the original change can
simply be reverted.
62bfae140 has only 2 lines left: a "char *name;" struct field, and a
line that prints a message. All other code was removed. The parsing code
in particular was made declarative, which replaced reading this element
explicitly (and other elements, see 1b22101c77). I'm putting the log
message under HAVE_GPL, but I don't think the declaration is
copyrightable, or the mere concept of reading this element. Redoing the
other 2 lines of code would result in the same program text.
d41e860ba was applied by someone who (potentially) disagreed. The patch
itself is from someone who did agree, though. It's unknown whether the
applier changed the patch. But it seems unlikely, and the change was
mostly rewritten.

When mpv is being linked against static libraries which have shared
libraries as dependencies, linker will throw error because pkg-config
with --static flag will return shared libraries which will be placed
under the -Wl,-Bstatic section, while pkg-config without --static flag
will omit the private libraries required to link the static library.
With this function users can modify the wscript to insert the dependencies
when necessary. For example, linking FFmpeg with shared OpenSSL and zlib:
'func': check_pkg_config_mixed(['crypto','ssl','z'], 'libavcodec')
Upstream provides pkgconfig files for quite some time now [1,2].
Use them to determine the required flags instead of hard coding.
This makes cross-compilation easy, which I dare to say is important for
many raspberry-pi users. This also prevents picking libEGL and libGLESv2
from mesa when they are present, which can happen with the current code.
Good distros should put these pkgconfig files into default pkg-config
search path or populate PKG_CONFIG_PATH for users. However, be nice to
everybody and manually look into '/opt/vc/lib/pkgconfig' just in case.
Hence the PKG_CONFIG_PATH mangling.

This reverts commit fae7307931.
Before the waf build system was used, we had a configure script written
in shell. To drop the build dependency on Python, someone rewrote the
Python scripts we had to Perl. Now the shell configure script is gone,
and it makes no sense to have a build dependency on both Perl and
Python.
This isn't just a straight revert. It adds the new Matroska EBML
elements to the old Python scripts, adjusts the waf build system, and of
course doesn't add anything back needed by the old build system.
It would be better if this used matroska.py/file2string.py directly by
importing them as modules, instead of calling them via "python". But for
now this is simpler.
The test ended up failing if cuda.h wasn't present, even if cuda.h
isn't used during the actual build.
This test is attempting to establish if the ffmpeg being built
against has dynlink_cuda support. While it might theoretically be
possible to build against the older normally-linked-cuda version
of ffmpeg, it seems more trouble than it's worth.
We always want to use __declspec(selectany) to declare GUIDs, but
manually including <initguid.h> in every file that used GUIDs was
error-prone. Since all <initguid.h> does is define INITGUID and include
<guiddef.h>, we can remove all references to <initguid.h> and just
compile with -DINITGUID to get the same effect.
Also, this partially reverts 622bcb0 by re-adding libuuid.a to the
build, since apparently some GUIDs (such as GUID_NULL) are not declared
in the source file, even when INITGUID is set.
For clang, it's enough to just put (void) around usages we are
intentionally ignoring the result of.
Since GCC does not seem to want to respect this decision, we are forced
to disable the warning globally.
I got a report that the build on a recent aarch64 Linux kernel failed.
DVB support was detected, but errored on compilation:
In file included from ../stream/stream_dvb.c:57:0:
../stream/dvbin.h:72:5: error: unknown type name 'fe_bandwidth_t'
fe_bandwidth_t bw;
Make the test stricter, which should take care of this. (I couldn't find
out what exactly triggered the failure, nor could I attempt to reproduce
it.)
The change in stream/dvbin.h is to make sure that this isn't caused by
incorrect header inclusion. It now includes the same files as the
configure test.
This sets the minimum supported Windows version to Windows Vista. The
subsystem version also affects some Windows API functions, including
GetSystemMetrics(SM_CXPADDEDBORDER).
This is based on an older patch by James Ross-Gowan. It was rebased and
cleaned up. Also, the DWM API usage present in the older patch was
removed, because DWM reports nonsense rates at least on Windows 8.1
(they are rounded to integers, just like with the old GDI API - except
the GDI API had a good excuse, as it could report only integers).

Make the GPU memcpy from the dxva2 code generally useful to other parts
of the player.
We need to check at configure time whether SSE intrinsics work at all.
(At least in this form, they won't work on clang, for example. It also
won't work on non-x86.)
Introduce a mp_image_copy_gpu(), and make the dxva2 code use it. Do some
awkward stuff to share the existing code used by mp_image_copy(). I'm
hoping that FFmpeg will sooner or later provide a function like this, so
we can remove most of this again. (There is a patch, bit it's stuck in
limbo since forever.)
All this is used by the following commit.
Some particular checks can define the HAVE_ key on their own. To make sure
they work correctly when composed (with compose_checks) we force the HAVE_
key to be undefined if a check fails.
Revert "win32: more wchar_t -> WCHAR replacements"
Revert "win32: replace wchar_t with WCHAR"
Doing a "partial" port of this makes no sense anymore from my
perspective. Revert the changes, as they're confusing without
context, maintenance, and progress. These changes were a bit
premature anyway, and might actually cause other issues
(locale neutrality etc. as it was pointed out).
This was essentially missing from commit 0b52ac8a.
Since L"..." string literals have the type wchar_t[], we can't use them
for UTF-16 strings. Use C11 u"..." string literals instead. These have
the type char16_t[], but we simply assume char16_t is the same
underlying type as WCHAR. In practice, they're both unsigned short.
For this reason use -std=c11 on Windows. Since Windows is a "special"
environment (we require either MinGW or Cygwin), we don't need to worry
too much about compiler compatibility.
Until now, it only used the hash from the previous configure run,
instead of trying to get the latest hash. The "old" build system did
this correctly - we just have to use the existing logic in version.sh.
Since waf supports separate build dirs, extend version.sh with an
argument for setting the path of version.h.
Arch linux is about to update to lua 5.3.x, but lua 5.2.x will be
provided by package lua52, which contains pkg-config file lua52.pc.

It's useless, and creates a bogus warning in subprocess-posix.c.
Since I don't know which compilers might have it by default, just change
it to -Wno-redundant-decls.
Add a platform-specific entry-point for Windows. This will allow some
platform-specific initialization to be added without the need for ugly
ifdeffery in main.c.
As an immediate advantage, mpv can now use a unicode entry-point and
convert the command line arguments to UTF-8 before passing them to
mpv_main, so osdep_preinit can be simplified a little bit.
It simply doesn't work, and is hard to make work. Lua 5.3 is a different
language from 5.1 and 5.2, and is different enough to make adding
support a major issue. Most importantly, 5.3 introduced integer types,
which completely mess up any code which deals with numbers.
I tried to make this a compile time check, but failed. Still at least
try to avoid selecting the 5.3 pkg-config package when the generic "lua"
name is used (why can't Lua upstream just provide an official .pc
file...). Maybe this actually covers all cases.
Fixes#1729 (kind of).
Starting to get tired of seeing the full config.h in verbose output
every time. Make it slightly more elegant by outputting the list of
satisfied dependencies instead.
Using check_statement() with an empty statement just to check for the
header is quite a hack. Fix check_headers() (so it takes a "use"
parameter), and use it for the checks instead.
This warning wasn't overly helpful in the past, and warned against
perfectly fine code. But at least with recent gcc versions, this is the
warning that complains about assignments in if expressions (why???), so
we want to enable it.
Also change all the code this warning complains about for no reason.
It is also used for initialization in channel-list setup.
Should fix compilation on FreeBSD, and is more correct
since it is used unconditionally.
Reverts 6445648 .
A use of NO_STREAM_ID_FILTER was added to the DVB code recently. While I
have no idea what it's needed for, it makes mpv fail to compile on
FreeBSD 10.1. Add it to the dvb configure check.
