Ancient AMD specific enhancement to the MMX instruction set. Officually
discontinued by AMD.
Note that support for this was already disabled in the previous commit.
This commit removes the actual code.
mplayer had three ways of enabling CPU specific assembler routines:
a) Enable them at compile time; crash if the CPU can't handle it.
b) Enable them at compile time, but let the configure script detect
your CPU. Your binary will only crash if you try to run it on a
different system that has less features than yours.
This was the default, I think.
c) Runtime detection.
The implementation of b) and c) suck. a) is not really feasible (it
sucks for users). Remove all code related to this, and use libav's CPU
detection instead. Now the configure script will always enable CPU
specific features, and disable them at runtime if libav reports them
not as available.
One implication is that now the compiler is always expected to handle
SSE (etc.) inline assembly at runtime, unless it's explicitly disabled.
Only checks for x86 CPU specific features are kept, the rest is either
unused or barely used.
Get rid of all the dump -mpcu, -march etc. flags. Trust the compiler
to select decent settings.
Get rid of support for the following operating systems:
- BSD/OS (some ancient BSD fork)
- QNX (don't care)
- BeOS (dead, Haiku support is still welcome)
- AIX (don't care)
- HP-UX (don't care)
- OS/2 (dead, actual support has been removed a while ago)
Remove the configure code for detecting the endianness. Instead, use
the standard header <endian.h>, which can be used if _GNU_SOURCE or
_BSD_SOURCE is defined. (Maybe these changes should have been in a
separate commit.)
Since this is a quite violent code removal orgy, and I'm testing only
on x86 32 bit Linux, expect regressions.
aclib[_template].c contained inline assembler versions of memcpy using
MMX/SSE/3dnow etc. instructions. It's possible that this gave quite a
speed a decade ago, but it's unlikely to have any use on modern
systems. Also, libc implementations already have their own
optimizations for the native memcpy function.
I did not verify my assumptions eith benchmarks, so I could be wrong.
Also note that some platforms have extremely crappy libc
implementations, and it's well possible that these might suffer from a
major performance loss (hello Windows). Unfortunately, I do not care.
mplayer doesn't use yasm, as or ranlib. They were only needed to
build with internal libav, which is gone.
Also, get rid of nm. nm was used to find out how external symbols are
mangled. Replace this by a platform check in mangle.h. As far as I
know, sane systems don't mangle symbols. Windows prefixes them with
an underscore ("_symbol"). I don't know about OSX.
The win32 emulation code can be used to load Windows binary codecs.
Unfortunately, this code is extremely whacky and unmaintained. It
consists of an ancient copy of wine, that was hacked to death and
back. It does super-whacky stuff like patching the loaded codecs at
fixed memory offsets to make them work.
Not removing yet, because it still has some limited use, and some of
the code is needed to load codecs when running natively on Windows.
(Actually, I only care because mplayer can get video input from the
webcam of that-one-latop under Windows, which I find far too neat to
just kill all the code.)
The previous commit made libass the default OSD renderer. This commit
removes the disabled freetype renderer completely. The commits were
done separately to make rolling back easier, because using libass for
OSD rendering is a risky choice.
Also remove freetype/fontconfig/fribidi code. This is all done by
libass now.
If mplayer is compiled without libass, no OSD is displayed.
The OSD will now be rendered with libass. The old rendering code, which
used freetype/fontconfig and did text layout manually, is disabled. To
re-enable the old code, use the --disable-libass-osd configure switch.
Some switches do nothing with the new code enabled, such as -subalign,
-sub-bg-alpha, -sub-bg-color, and many more. (The reason is mostly that
the code for rendering unstyled subtitles with libass doesn't make any
attempts to support them. Some of them could be supported in theory.)
Teletext rendering is not implemented in the new OSD rendering code. I
don't have any teletext sources for testing, and since teletext is
being phased out world-wide, the need for this is questionable.
Note that rendering is extremely inefficient, mostly because the libass
output is blended with the extremely strange mplayer OSD format. This
could be improved at a later point.
Remove most OSD rendering from vo_aa.c, because that was extremely
hacky, can't be made work with osd_libass, and didn't work anyway in
my tests.
Internally, some cleanup is done. Subtitle and OSD related variable
declarations were literally all over the place. Move them to sub.h and
sub.c, which were hoarding most of these declarations already. Make the
player core in mplayer.c free of concerns like bitmap font loading.
The old OSD rendering code has been moved to osd_ft.c. The font_load.c
and font_load_ft.c are only needed and compiled if the old OSD
rendering code is configured.
This enables playing URLs from libquvi supported streaming sites
directly, e.g. "mplayer http://www.youtube.com/watch?v=...."
Anything opened with mplayer is checked with libquvi. If it looks like
a URL of a supported streaming site, libquvi is used to extract the
media URL, which is then passed to the lower level mplayer code
instead of the HTML URL. Hopefully the libquvi URL checker works well
enough that it doesn't cause any problems with normal URLs, files, or
whatever else mplayer's stream layer accepts.
Add the --libquvi-format option. the option value is directly passed to
libquvi as requested format. The only values that seem to work for any
streaming site seem to be "best" (best quality) and "default" (lowest
quality). The mplayer option defaults to "best" (overriding libquvi's
default).
Outstanding issues:
- Does libquvi checking every opened file really not cause problems?
Should there be a runtime option to disable libquvi use?
(Probably not an issue.)
- Should we check/set the supported protocol? By default libquvi has
support for all protocols enabled. In the worst case, it might return
an URL using a protocol not supported by mplayer, even though it
could extract URLs with other protocols too.
(Probably not an issue.)
- Somehow export metadata (like media title) to the mplayer frontend?
Some of these have only limited use, and some of these have no use at
all. Remove them. They make maintainance harder and nobody needs them.
It's possible that many of the removed drivers were very useful a dozen
of years ago, but now it's 2012.
Note that some of these could be added back, in case they were more
useful than I thought. But right now, they are just a burden.
Reason for removal for each module:
vo_3dfx, vo_dfbmga, vo_dxr3, vo_ivtv, vo_mga, vo_s3fb,
vo_tdfxfb, vo_xmga, vo_tdfx_vid:
All of these are for very specific and outdated hardware. Some
of them require non-standard kernel drivers or do direct HW
access.
vo_dga: the most crappy and ancient way to get fast output on X.
vo_aa: there's vo_caca for the same purpose.
vo_ggi: this never lived, and is entirely useless.
vo_mpegpes: for DVB cards, I can't test this and it's crappy.
vo_fbdev, vo_fbdev2: there's vo_directfb2
vo_bl: what is this even? But it's neither important, nor alive.
vo_svga, vo_vesa: you want to use this? You can't be serious.
vo_wii: I can't test this, and who the hell uses this?
vo_xvr100: some Sun thing.
vo_xover: only useful in connection with xvr100.
ao_nas: still alive, but I doubt it has any meaning today.
ao_sun: Sun.
ao_win32: use ao_dsound or ao_portaudio instead.
ao_ivtv: removed along vo_ivtv.
Also get rid of anything SDL related. SDL 1.x is total crap for video
output, and will be replaced with SDL 2.x soon (perhaps), so if you
want to use SDL, write output drivers for SDL 2.x.
Additionally, I accidentally damaged Sun support, which made me
completely remove Sun/Solaris support. Nobody cares about this anyway.
Some left overs from previous commits removing modules were cleaned up.
Conflicts:
.gitignore
bstr.c
cfg-mplayer.h
defaultopts.c
libvo/video_out.c
The conflict in bstr.c is due to uau adding a bstr_getline function in
commit 2ba8b91a97. This function already existed in this branch.
While uau's function is obviously derived from mine, it's incompatible.
His function preserves line breaks, while mine strips them. Add a
bstr_strip_linebreaks function, fix all other uses of bstr_getline, and
pick uau's implementation.
In .gitignore, change vo_gl3_shaders.h to use an absolute path
additional to resolving the merge conflict.
The player can read codec mapping (codecs.conf) from an external file
or use embedded defaults. Before, the defaults were stored in the
player binary in the form of final already-parsed data structures.
Simplify things by storing the text of the codecs.conf file instead,
and parse that at runtime the same way an external file would be
parsed.
To create the previous parsed form, the build system first compiled a
separate binary named "codec-cfg", which parsed etc/codecs.conf and
then wrote the results as a C data structure that could be compiled
into the program. The new simple conversion of codecs.conf into a C
string is handled by the new script TOOLS/file2string.py.
After removing the codec-cfg binary, HOST_CC is no longer used for
anything. Remove the --host-cc configure option and associated logic.
Also remove the codec2html and codec-cfg-test functionality. Building
those was already broken and nobody cared.
There was a broken 3-character-long "fourcc" entry in etc/codecs.conf.
This happened to be accepted before but triggered a parse error after
the changes. Remove the broken entry and make the parsing functions
explicitly test for this error.
The configure script adds some compiler-specific flags for GCC on OSX.
This was done under a check for compiler binary name not being clang.
Move the test to after $cc_vendor has been determined and check
against that instead.
The previous test worked for clang if you explicitly specified
--cc=clang, but not if the default system "cc" command was used and
mapped to clang. Recent versions of Xcode changed the default compiler
(cc) to clang. This caused a lot of spam from clang, which complained
about the unknown flags when compiling with no explicit --cc option.
The OpenGL autodetection checked for all backends regardless of which
features had been enabled previously. Stop checking for X11 backend if
X11 support is disabled, and stop checking for w32 backend if we are
not on Windows.
This makes the changes in commit 3862d469ae ("configure: OSX: check
for X11 header conflict with corevideo") work as intended. That commit
disabled X11 when a header conflict was detected, but the GL X11
backend could still be autodetected despite that and trigger a
compilation failure.
This AO has potential to be useful on platforms other than Linux. On
Windows in particular, PortAudio can make use of newer/better audio
APIs like WASAPI, instead of DirectSound.
As an implementation choice, the PortAudio callback API was used. The
blocking API might be a better match for mplayer's requirements, but
caused severe problems on Linux/ALSA (possibly PortAudio bugs).

Merge of cocoa_common.m done by pigoz.
Picking my version of screenshot.c. The fix in commit aadf1002f8 will

conflicts with the work done locally in this branch, and other work in
progress.
Check that headers from ApplicationServices and X11 do not conflict
before enabling X11 support on OSX. Both headers would be included in
vo_corevideo.m (through QuartzCore/QuartzCore.h and gl_common.h). The
conflict exists on versions of Mac OSX prior to 10.7, where
ApplicationServices includes the deprecated QuickDraw framework,
resulting in a clash on the Cursor type definition.
Run dlopen on the OpenGL dynamic library instead of on the binary.
This should prevent crashes due to function conflicts when X11/lGL is
linked.
Remove mutual exclusion of the X11 and Cocoa backends.
Add code to wake up the select() call in input.c when an OSX event is
available and a Cocoa OpenGL backend is initialized.
Fixes the slow response to input or other events in Cocoa-based VOs
during long select() sleeps (e.g., when mplayer2 is paused) introduced
by commit 7040968.
This OSX video output is replaces the previous shared_buffer mode of
vo_corevideo. It manages a shared buffer and a Cocoa distributed
object to communicate with GUIs.
Splitting this code into a separate VO allows to get rid of harmful
code coupling, performance inefficiencies (useless image memory
copies) and ugly code (big if-else conditionals).
Change vo_corevideo to use cocoa_common to create and manage the
window. This doesn't affect external OSX GUIs, since they don't use
vo_corevideo window management, but only read the image data from the
shared buffer.
The --enable-debug and --enable-profile options set their own compiler
flags, completely different from normal flag selection. These flags
sucked; especially '-W' (an obsolete alias for '-Wextra') generated a
huge number of irrelevant warnings. Change configure to only add "-g"
or similar to the flags that would be used otherwise.
This new vo is heavily based on vo_gl.c. It provides better scale
filters, dithering, and optional color management with LittleCMS2.
It requires OpenGL 3.
Many features are enabled by default, so it will be slower than vo_gl.
However, it can be tuned to behave almost as vo_gl.
The recommended way to get function pointers to the functions in the
OpenGL library is through dlopen/dlsym/dlclose. This causes problems
in the Cocoa OpenGL backend when -lGL (X11's OpenGL headers) is linked
to the binary together with -framework OpenGL.
The linked OpenGL symbols are always from -lGL, causing all the
function pointers to point to null when getFunctions is called against
a Cocoa OpenGL context.
For this reason change the configure autodetection code to disable
the vo_gl X11 backend when cocoa is active.
This video output is not useful anymore. It is based on Carbon to draw
the mplayer window and this has been deprecated by Apple in 10.5.
The upcoming 10.8 OSX release should deprecate most of Carbon, so it
doesn't make sense to keep vo_quartz in the codebase when there are
modern and better alternatives (vo_gl and vo_corevideo).
macosx_finder_args was using Carbon and wasn't usable any longer on
modern versions of MacOSX. This is very useful to embed mplayer in a
mac application bundle.
When using application bundles, the operating system will call the
main function with only one argument that identifies the process
serial number (this is some additional process identifier in osx other
than the pid). File open events are then dispatched to the application
through events that must be handled accordingly.
Latest liblivemedia version disables APIs we need. The code still
exists in the library and the changelog says the old interface can be
enabled with "#define RTSPCLIENT_SYNCHRONOUS_INTERFACE". However, the
code on the library side is disabled by default too, and seems to be
disabled in distro packages, so defining that in the player does not
help (just delays the failure until link time). It's possible the
distro packages will be changed to enable this, but since dropping
live555 support is desirable anyway, change configure to disable
support by default at least for now.
The live555 code is the only part of the source that's in C++.
Including C headers in code compiled as C++ has caused issues at
times, so deleting this code would have a maintenance benefit.
Reportedly the rtsp support in Libav has improved, so there should
be less need for live555.
This makes MinGW redirect certain stdio functions (such as the sprintf
family) from the MSVCRT libc to a standard compliant MinGW
implementation.
This fixes a crash in talloc.c when compiling mplayer with MinGW-w64.
The problem is most likely with talloc_vasprintf(), which calls
vsnprintf with a small buffer and checks its return value to find out
how much space the formatted string requires. Without this commit,
vsnprintf would always return -1, and then the code calls abort().
(lachs0r figured out this one.)
If --enable-cross-compile is specified, passing
--target=i686-w64-mingw32 for example will check if
i686-w64-mingw32-gcc can be used. This is only done if the compiler
isn't specified via --cc or the CC environment variable.
The same is done for some other build tools, such as pkg-config.
(Only the C compiler will try to use a fallback in this case.)
This didn't work very well when cross compiling from Linux to Windows:
it tries to execute an .exe file, which succeeds if wine is installed.
As consequence it detects "no" as result.
In general this won't work if emulation for the target architecture is
available. Remove it.
When the build wrapper repo scripts run configure they set a custom
PKG_CONFIG_PATH environment variable. Show the value of this in
config.log to make it easier to rerun configure with a tweaked version
of the same parameters. Also show CFLAGS if set, as it's likely to
break things.
Remove "Please check mtrr settings at /proc/mtrr" and "NOTE: Win32
codec DLLs are not supported on your CPU" messages printed at the end
of a configure run. mtrr should be irrelevant on today's machines, and
the DLLs are a lot less important nowadays. Also remove mtrr detection
logic that was only used to decide whether or not to print that
message. Bizarrely, there were --enable-mtrr and --disable-mtrr
options for this too (with no effect except for the message).
libpostproc has been removed from Libav and the library now exists as
a separate project. Because it's not essential, separate it from the
Libav library check and allow compiling without it.
Add helper function pkg_config_add() that checks for the presence of a
package and also adds cflags/ldflags if it is found. Change existing
pkg-config-using feature tests to use that. Also change the freetype
test that used a separate libfreetype-config binary before; using
pkg-config instead helps cross-compiling. Drop other kinds of checks
(such as test compiles) from these tests. It's possible that this
could cause problems on some (broken) systems, but that can't be
verified without user testing.
Change various code to use the latest Libav API. The libavcodec
error_recognition setting has been removed and replaced with different
semantics. I removed the "--lavdopts=er=<value>" option accordingly,
as I don't think it's widely enough used to be worth attempting to
emulate the old option semantics using the new API. A new option with
the new semantics can be added later if needed.
Libav dropped APIs that were necessary with all Libav versions
until quite recently (like setting avctx->age), and it would thus not
be possible to keep compatibility with previous Libav versions without
adding workarounds. The new APIs also had some bugs/limitations in the
recent Libav release 0.8, and it would not work fully (at least some
avcodec options would not be set correctly). Because of those issues,
this commit makes no attempt to maintain compatibility with anything
but the latest Libav git head. Hopefully the required fixes and
improvements will be included in a following Libav point release.
Require versions of the Libav libraries corresponding to Libav release
0.7. These are:
libavutil 51.7.0
libavcodec 53.5.0
libavformat 53.2.0
libswscale 2.0.0
libpostproc 52.0.0
Also disable the fallback to simple header check if these libraries
could not be found with pkg-config; now compiling without pkg-config
support for these always requires explicitly setting --enable-libav
and any needed compiler/linker flags. The simple check would have let
compilation proceed even if a version mismatch was detected.
