mpcommon.c used to be the only file to include version.h. version.h is
generated by the build system, and contains the git revision. Any time
a commit is made (or the tree is rebased etc.), the file is rewritten,
and mpcommon.c rebuilt. To make rebuilding less annoying, the definition
of the version string is the only thing in mpcommon.c.
Since I want to add other things to mpcommon.c, add a new file named
version.c, that takes over mpcommon.c's role as described above.
mpcommon.c doesn't include version.h anymore, and will be used to park
code that doesn't really belong anywhere else.
Split the vo_vdpau code that calculates how to pack all subtitle
bitmaps into a larger surface into a separate file. This will allow
using it in other VOs.
Conflicts:
Makefile
libvo/vo_vdpau.c
Note: this commit does the same as an earlier commit by me
(4010dd0b1a). My commit added the vo_vdpau packer code as
eosd_packer.c, while this commit by uau uses bitmap_packer.c. Since
bitmap_packer.c has a different interface, and because there are more
commits changing OSD rendering coming, I will pick uau's version.
However, vo_gl, vo_gl3 and vo_direct3d are still using eosd_packer.c,
so to make the transition easier, don't delete eosd_packer.c yet.
Change libavcodec subtitle decoding code (used for some bitmap
subtitle types) to use the same decoding framework as sd_ass. The
functionality that was previously in av_sub.c and was directly called
from mplayer.c is now in sd_lavc.c.
Conflicts:
mplayer.c
sub/av_sub.h
sub/sd_lavc.c
Merged from mplayer2. The remaining use of is_av_sub() is replaced by
a check whether a subtitle decoder is active, which should give the
same results.
Probably all of these are supported by libavcodec. Missing things can
be added back.
Also remove qtpalette.h. It was used by demux_mov.c, and should have
been deleted with commit 1fde09db6f.
The main excuse for removing this is that LIVE555 deprecated the API
the mplayer implementation was using. The old API still seems to be
somewhat supported, but must be explicitly enabled at LIVE555
compilation, so mplayer won't always work on any user installation.
The implementation was also very messy, in C++, and FFmpeg support is
available as alternative.
Remove it completely.
libavformat replaces demux_audio completely. I don't know/care what
vivo (demux_viv) is. libavformat has a Real demuxer; it seems it works
slightly better, with a different set of bugs.
Support for internal libdvdread has been removed in commit 41fbcee1f5,
but some bits have been missed in Makefile/configure.
Support for libdvdread as normal library is left unchanged.
While being able to play videos on a framebuffer device would be nice,
I didn't need it, and couldn't even test it (buggy nvidia binary
drivers that disable framebuffers, buggy DirectFB that crashes when
using the X11 backend). It's just dead weight, get rid of it.
vo_directx was very horrible, and by today it's mostly useless. I didn't
remove it, because there was that-guy who told me in amazement how
awesome mplayer was, because it was the only video player fast enough
for fast playback on his system when using vo_directx. Sorry, that-guy.
When the internal mplayer MPEG demuxer was removed (commit 1fde09db),
the default demuxer when using dvdnav was set to libavformat. Now it
turns out that this doesn't work with libavformat. It will terminate
playback right after the audio runs out (instead of looping it like the
video, or whatever it's supposed to do). I'm not sure what exactly the
problem is, but since 1. even mplayer-svn can't handle DVD menus
directly (missing highlights), 2. DVD menus are essentially worthless,
and 3. I don't directly watch DVDs, don't bother with it and remove it.
For basic playback, there's still libdvdread support.
Also, use pkg-config for libdvdread, and drop support for in-tree
libdvdread. Remove support for in-tree libdvdcss as well.
Remove the win32 loader - the win32 emulation layer, as well as the
code for using DirectShow/DMO/VFW codecs. Remove loading of xanim,
QuickTime, and RealMedia codecs.
The win32 emulation layer is based on a very old version of wine.
Apparently, wine code was copied and hacked until it was somehow able
to load a limited collection of binary codecs. It poked around in the
code segment of some known binary codecs to disable unsupported win32
API calls to make them work. Example from module.c:
for (i=0;i<5;i++) RVA(0x19e842)[i]=0x90; // make_new_region ?
for (i=0;i<28;i++) RVA(0x19e86d)[i]=0x90; // call__call_CreateCompatibleDC ?
for (i=0;i<5;i++) RVA(0x19e898)[i]=0x90; // jmp_to_call_loadbitmap ?
for (i=0;i<9;i++) RVA(0x19e8ac)[i]=0x90; // call__calls_OLE_shit ?
for (i=0;i<106;i++) RVA(0x261b10)[i]=0x90; // disable threads
Just to show how utterly insane this code is. You wouldn't want even
your worst enemy to have to maintain this. In fact, it seems nobody
made major changes to this code ever since it was committed.
Most formats can be decoded by libavcodecs these days, and the loader
couldn't be used on 64 bit platforms anyway. The same is (probably)
true for the other binary codecs.
General note about how support for win32 codecs could be added back:
It's not possible to replace the win32 loader code by using wine as
library, because modern wine can not be linked with native Linux
programs for certain reasons. It would be possible to to move DirectShow
video decoding into a separate process linked with wine, like the
CoreAVC-for-Linux patches do. There is also the mplayer-ww fork, which
uses the dshownative library to use DirectShow codecs on Windows.
Since slave mode is not planned to be kept, this VO is useless and I'm
removing it.
This VO was useful for OSX GUIs. Since in cocoa you can't embed views in
windows from other processes, this VO was writing to a sharedbuffer with
mmap. The OSX GUIs would then read from the buffer and render the image
with an external renderer.
If in the future we will want to support GUIs we will need to reasearch the
IOSurface framework. This allows to share kernel managed image data
across processes and integrates well with OpenGL.
This transition to a new VO API started over 4 years ago. It's time to
finally end it, and get rid of the horrible hacks.
Also removes some previously undetected dead code from spudec.c.
The removed VO and AO took MPEG data and decoded it with V4L2. I'm not
exactly sure what's the use of this today, but get rid of it.
As far as feeding video data to V4L2 is concerned, there are other
ways. For example, there is this script, that feeds yuv4mpeg formatted
raw video data to V4L2:
https://raw.github.com/umlaeute/v4l2loopback/master/examples/yuv4mpeg_to_v4l2.c
The encoding branch by divverent can handle of these via libavformat.
Note: for some reason, libav/ffmpeg have a GIF muxer only, and no
demuxer. The gif configure checks needef for the mplayer internal gif
demuxer can't be removed yet.

Teletext requires special OSD support. Because I can't even test
teletext, I can't restore support for it. Since teletext can be
considered ancient and obscure, and since it doesn't make sense to keep
the remaining teletext code without being able to use it, I'm removing
it.
stream_cue, which provided the cue:// protocol handler, was extremely
hacky and didn't even manage to play some samples I tried.
Remove it, because it's plain unneeded. There is much better support
for .cue files elsewhere:
- libcdio can play pairs of .cue/.bin files:
mplayer cdda:// --cdrom-device=your_cue_file.cue
Note that if the .cue file is not accompanied by a .cue file, but
an encoded file for example, this most likely won't work.
- mplayer can play .cue files directly:
mplayer your_cue_file.cue
This works, even if the .cue file comes with encoded files that are
not .bin . Note that if you play .bin files, mplayer will assume a
specific raw audio format. If the format doesn't match, mplayer will
play noise and destroy your speakers. Note that format mismatches are
extremely common, because the endianness seems to be essentially
random. (libcdio uses a clever algorithm to detect the endian, and
doesn't have this problem.)
To quote the manpage: "This filter is untested, maybe even unusable."
And it seems they were never touched again after it was added many
years ago (except for cosmetic changes). Just get rid of them.
About a year ago, ubitux converted most of the old manpage from the
hard to maintain nroff format to reStructuredText. This was not merged
back into the master repository immediately. The argument was that the
new manpage still required work to be done. However, progress was very
slow. Even worse: the old manpage wasn't updated, because it was
scheduled for deletion, and updating it would have meant useless work.
Now the situation is that the new manpage still isn't finished, and the
old manpage is grossly out of sync with the player. This is not helpful
for users. Additionally, keeping the new manpage in a separate branch,
while the normal development repository for code had the old manpage,
was very inconvenient, because you couldn't just update the
documentation in the same commit as the code.
Even though the new manpage isn't finished yet, merging it now seems to
be the best course of action. Squash-merge the manpage development
branch [1], revision e89f5dd3f2, which branches from the mplayer2
master branch after revision 159102e0cb.
Committers:
* Clément Bœsch <ubitux@gmail.com> (Initial conversion to RST.)
* Uoti Urpala <uau@mplayer2.org> (Many updates.)
* Myself (Minor edits.)
Most text of the manpage has been directly taken from the old manpage,
because this is a conversion, not a complete rewrite.

There is no reason why generated source files shouldn't be part of the
clean target, as opposed to distclean. On the contrary, having them
in distclean only looks dangerous when trying to deal with broken
dependency rules. Move them to clean, except config.h (which would
require configure to be run again).
Also, some recently added generated files were missing from the clean
targets.
This was a horrible little tool to detect the host CPU at build time.
Forgotten in commit 74df1d8e05.
Also remove forgotten codec-cfg entry in .gitignore .
The internal array of default key bindings is removed. Include the
file etc/input.conf at compile time (using the file2header tool), and
parse the default binds from etc/input.conf at startup time.
This lowers maintainance overhead, and makes sure the default bindings
and etc/input.conf don't deviate. Commit f30bf73bf2 already
made sure etc/input.conf matches the default bindings, so this commit
shouldn't change anything user-visible.
There are still various other RTSP implementations available, such as
libnemesi, live555, and libav. The mplayer native version was a huge
chunk of old unmaintained code.
This was done with the help of callcatcher [1]. Only functions which
are statically known to be unused are removed.
Some unused functions are not removed yet, because they might be needed
in the near future (such as open_output_stream for the encode branch).
There is one user visible change: the --subcc option did nothing, and is
removed with this commit.
[1] http://www.skynet.ie/~caolan/Packages/callcatcher.html
Summary:
- There is no playtree anymore. It's reduced to a simple list.
- Options are now always global. You can still have per-file options,
but these are optional and require special syntax.
- The slave command pt_step has been removed, and playlist_next
and playlist_prev added. (See etc/input.conf changes.)
This is a user visible incompatible change, and will break slave-mode
applications.
- The pt_clear slave command is renamed to playlist_clear.
- Playtree entries could have multiple files. This is not the case
anymore, and playlist entries have always exactly one entry. Whenever
something adds more than one file (like ASX playlists or dvd:// or
dvdnav:// on the command line), all files are added as separate
playlist entries.
Note that some of the changes are quite deep and violent. Expect
regressions.
The playlist parsing code in particular is of low quality. I didn't try
to improve it, and merely spent to least effort necessary to keep it
somehow working. (Especially ASX playlist handling.)
The playtree code was complicated and bloated. It was also barely used.
Most users don't even know that mplayer manages the playlist as tree,
or how to use it. The most obscure features was probably specifying a
tree on command line (with '{' and '}' to create/close tree nodes). It
filled the player code with complexity and confused users with weird
slave commands like pt_up.
Replace the playtree with a simple flat playlist. Playlist parsers that
actually return trees are changed to append all files to the playlist
pre-order.
It used to be the responsibility of the playtree code to change per-file
config options. Now this is done by the player core, and the playlist
code is free of such details.
Options are not per-file by default anymore. This was a very obscure and
complicated feature that confused even experienced users. Consider the
following command line:
mplayer file1.mkv file2.mkv --no-audio file3.mkv
This will disable the audio for file2.mkv only, because options are
per-file by default. To make the option affect all files, you're
supposed to put it before the first file.
This is bad, because normally you don't need per-file options. They are
very rarely needed, and the only reasonable use cases I can imagine are
use of the encode backend (mplayer encode branch), or for debugging. The
normal use case is made harder, and the feature is perceived as bug.
Even worse, correct usage is hard to explain for users.
Make all options global by default. The position of an option isn't
significant anymore (except for options that compensate each other,
consider --shuffle --no-shuffle).
One other important change is that no options are reset anymore if a
new file is started. If you change settings with slave mode commands,
they will not be changed by playing a new file. (Exceptions include
settings that are too file specific, like audio/subtitle stream
selection.)
There is still some need for per-file options. Debugging and encoding
are use cases that profit from per-file options. Per-file profiles (as
well as per-protocol and per-VO/AO options) need the implementation
related mechanisms to backup and restore options when the playback file
changes.
Simplify the save-slot stuff, which is possible because there is no
hierarchical play tree anymore. Now there's a simple backup field.
Add a way to specify per-file options on command line. Example:
mplayer f1.mkv -o0 --{ -o1 f2.mkv -o2 f3.mkv --} f4.mkv -o3
will have the following options per file set:
f1.mkv, f4.mkv: -o0 -o3
f2.mkv, f3.mkv: -o0 -o3 -o1 -o2
The options --{ and --} start and end per-file options. All files inside
the { } will be affected by the options equally (similar to how global
options and multiple files are handled). When playback of a file starts,
the per-file options are set according to the command line. When
playback ends, the per-file options are restored to the values when
playback started.
Most of these demuxers and decoders are provided in better form by
libav, while the mplayer builtin ones are essentially unmaintained. The
only legimitate use case for not using the libav ones was working around
libav bugs or bugs related to the way mplayer uses libav. Instead of
trying to keep dead code alive, development effort should go into
improving libav or the mplayer libav glue code.
Note that the libav demuxer have been preferred over the mplayer builtin
ones for a while in mplayer2. There were some exceptions: playing DVDs
with dvdnav or playing network sources. (That's because some stream
modules and network.c requested explicit file formats, such as
DEMUXER_TYPE_MPEG_PS, which mapped to builtin demuxers.) With this
commit, they are switched to use libav. One caveat is that the requested
format is not passed to libavformat, instead we rely on the auto probing
to select the correct libav demuxer (see code in demux_open_stream()).
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.
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.
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.
Explicit dependency rules are needed when a source file depends on an
autogenerated file. Move these rules to the same place in the Makefile
as the rules for creating the generated files.
Also, change the rules to declare the direct dependency, not a
transitive one (e.g. codecs.conf.h is needed by codec-cfg.c, not
codec-cfg.o). In practice, this shouldn't change anything, but it's
cleaner.
While DOCS/tech/ contains lots of documentation about mplayer's
internals, most of it seems outdated, and hasn't been touched in many
years. On the other hand, there still might be useful things in there,
but it's hard to tell which parts.
Instead of deleting all it, rename the directory to "warn" potential
developers that the documentation is completely outdated.
I have no idea what these are about, but it's probably useless outdated
crap. According to TOOLS/README, they are wrappers around
some Real binary codecs. They were added in 2003, and never touched
again (except for cosmetic changes).
