rawvideo is a rather primitive demuxer that doesn't implement track
switching. The problem was that during track switching the demuxer
implementations normally set the stream IDs in order to do the switch,
and since rawvideo obviously didn't do that, so the current stream in
ds->sh / demuxer->video->sh was set to NULL. (The frontend always
assumes track switching is successful, which is a reasonable
assumption - failing due to missing video codecs etc. is in separate
codepaths.) Later, demux_rawvideo_fill_buffer() in demux_rawvideo.c
tried to dereference the NULL stream and crashed.
Other trivial single-stream demuxers worked fine, because they didn't
try to access ds->sh.
Someone wanted this. Apparently both libavformat's TS demuxer and
demux_ts are crap, and work/fail in different cases.
This demuxer has been removed in 1fde09db6f. All code added comes
from the revision before that. Some required bits have been added in
the commit before this one (re-adding demux_mpg), in particular the
changes to video.c.
stream_dvb will use this demuxer by default, otherwise demux_lavf is
preferred (as it has been before).
Some TS related command line options are not re-added.
Closed captions might not work.
Apparently this was needed for good DVD playback.
This demuxer has been removed in 1fde09db6f. All code added comes
from the revision before that. Some other bits have been removed in
later commits, and are added back as well.
Usage of memalign() is replaced by av_malloc(). As far as I can tell,
this memory is never free'd or reallocated, so no calls to av_free()
have been added.
The code re-added to video.c is plain horrible, full of code
duplication, full of demuxer/codecs specifics, but apparently needed.
Unrelated to re-adding the demuxer, re-add one codepath for
DEMUXER_TYPE_TV, which was accidentally removed in the same commit
demux_mpg was removed.
The closed captions decoder is not re-added.
The rawaudio demuxer had a rather hard to use way to set the audio
format with the --rawaudio=format=value option. The user had to pass a
numeric value, which then was set as wFormatTag member in the
WAVEFORMATEX header.
Make it use the mplayer audio format (the same as --af=format=value).
Add a new internal pseudo audio codec tag, which is hopefully unused,
which makes ad_pcm use the value in wFormatTag as internal mplayer
audio format.
Playing non-PCM formats is disabled. (At least AC3 can be played
directly.)
This was needed by the now-removed mov demuxer for QuickTime video, or
to be more specific, the Sorenson 3 video codec. QuickTime can
(probably) still decoded by libavcodec, but this field is not needed
for this.
The reference in demux_mkv was apparently for decoding QuickTime in
Matroska, using binary QuickTime codecs (QTX stuff). It's possible that
this has been broken with the binary codecs removal (see commit
aebfbbf2bd), because it removed related code from demux_mkv. On the
other hand, the code section in question was enabled only if binary
win32 codecs were enabled. The win32 codec loader worked on 32 bit x86
only. This means QuickTime-in-Matroska was broken on all other
architectures, including 64 bit x86. Despite being possibly broken on a
major platform, nobody has complained about it yet, and since I couldn't
find a sample of such a mkv file, so don't bother with it.
demux_lavf and demux_mkv, which both support demuxing subtitles, set
the global variable sub_utf8. This variable is connected with the -utf8
option, and should not be reset by code. Since demuxer subtitles are not
influenced by this option (anymore?), this is unnecessary. Remove the
code setting this variable from the demuxers.
Add all subtitle tracks as reported by libdvdread at playback start.
Display language for subtitle and audio tracks. This commit restores
these features to the state when demux_mpg was default for DVD playback,
and makes them work with demux_lavf and the recent changes to subtitle
selection in the frontend.
demux_mpg, which was the default demuxer for DVD playback, reordered
the subtitle streams according to the "logical" subtitle track number,
which conforms to the track layout reported by libdvdread, and is what
stream_dvd expects for the STREAM_CTRL_GET_LANG call. demux_lavf, on
the other hand, adds the streams in the order it encounters them in
the MPEG stream. It seems this order is essentially random, and can't
be mapped easily to what stream_dvd expects.
Solve this by making demux_lavf hand out the MPEG stream IDs (using the
demuxer_id field). The MPEG IDs are mapped by mplayer.c by special
casing DVD playback (map_id_from/to_demuxer() functions). This mapping
is essentially the same what demux_mpg did. Making demux_lavf reorder
the streams is out of the question, because its stream handling is
already messy enough.
(Note that demux_lavf doesn't export stream IDs for other formats,
because most time libavformat demuxers do not set AVStream.id, and we
don't know which demuxers do. But we know that MPEG is safe.)
Another major complication is that subtitle tracks are added lazily, as
soon as the demuxer encounters the first subtitle packet for a given
subtitle stream. Add the streams in advance. If a yet non-existent
stream is selected, demux_lavf must be made to auto-select that subtitle
stream as soon as it is added. Otherwise, the first subtitle packet
would be lost. This is done by DEMUXER_CTRL_PRESELECT_SUBTITLE.
demux_mpg didn't need this: the frontend code could just set ds->id to
the desired stream number. But demux_lavf's stream IDs don't map
directly to the stream number as used by libdvdread, which is why this
hack is needed.
Add a new slave property which switches the current Matroska edition.
Since each edition can define an entirely new timeline, switching the
edition will simply restart playback at the beginning of the file with
the new edition selected.
Add 'E' as new keybinding to step the edition property.
DVD titles are still separate. Apparently they work similarly, but I
don't have any multi-title DVDs for testing. Also, cdda (for audio CDs)
uses the same mechanism as DVDs to report a number of titles, so there
seems to be confusion what exactly this mechanism is supposed to do.
That's why the edition code is completely separate for now.
Remove demuxer.num_titles. It was just a rather useless cache for the
return value of the DVD titles related STREAM_CTRL.
One rather obscure corner case isn't taken care of: if the ordered
chapters file has file local options set, they are reset on playback
restart. This is unexpected, because edition switching is meant to
behave like seeking back to the beginning of the file.
Introduce a general track struct for every audio/video/subtitle track
known to the frontend. External files (subtitles) are now represented
as tracks too. This mainly serves to clean up the subtitle selection
code: now every subtitle is simply a track, instead of using a messy
numbering that goes by subtitle type (as it was stored in the
global_sub_pos field). The mplayer fontend will list external subtitle
files as additional tracks.
The timeline code now tries to match the exact demuxer IDs of all
tracks. This may cause problems when Matroska files with different
track numberings are used with EDL timelines. Change demux_lavf not
to set demuxer IDs, since most time they are not set.
af_format.h declares some symbols which are defined in format.c. The
fact that af_format.c is a completely unrelated file is rather
confusing. Having the header and implementation file use the same base
name is more uniform. (af_format.c is the audio conversion filter, while
af_format.h and format.c are about audio formats and their properties.)
Also fix all source files which include this file.
If either of them is not defined, the old behavior is used:
- the colormatrix is guessed based on resolution.
- the color range is assumed to be tv aka limited range.
The only decoder which could handle demux_gif's output was vd_raw,
which has been removed recently. Instead of re-adding vd_raw, make it
work with vd_ffmpeg.
By coincidence, the FourCC "raw " fits our needs and it understood by
the ffmpeg raw decoder (apparently used in mov files going by
libavcodec/rawdec.c). Since there doesn't seem to be any good way to
transport the palette in mplayer dmuxer packets, create an AVPacket for
this purpose. (struct sh_video provides a "global" palette. Rather than
hacking vd_ffmpeg to use it, it seems cleaner to make demux_gif use
AVPacket, which supports a per-frame palette.)
Change vd_ffmpeg such that if sh_video->format is a mplayer pixel
format, and there's no other codec information, try to play it as raw
video. (The case of no codec information happens if the "generic" ffmpeg
decoder is instantiated, which is tried last. This means clashes with
actual existing formats are less likely.)
demux_mng did not initialize all fields of the bih, which made vd_ffmpeg
do invalid memory accesses when trying to copy the extradata. Also, use
IMGFMT_RGB32 instead of creating the FourCC directly. (They should be
the same, but what if mplayer changes the IMGFMT_* values.)
This also fixes demux_rawvideo.
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.
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.
Libavformat does not distinguish between "no codec_tag given" and
"codec_tag given, value is 0". 0 can be a valid value. Change
demux_lavf to assume that 0 always means unset for audio. This
prevents incorrect selection of the PCM decoder, which includes
"format 0x0" in its codecs.conf entry. The video case accepts 0 iff
codec_id is RAWVIDEO, but there's no obvious similar check possible
for audio. Thus this could possibly cause issues if a file really uses
0 to mean uncompressed audio.
Commit 9c02ae7e95 set the sh variable (see diff) to the struct of
type sh_sub instead the one of sh_stream. Unfortunately this didn't
crash, and merely made the OSD show "unknown" for the language.
Commit 804bf91570 accidentally removed the display of the track
title. Add it back.
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
There are different C types for each stream type: sh_video for video,
sh_audio for audio, sh_sub for sub. There is no type that handles all
stream types in a generic way. Instead, there's a macro SH_COMMON, that
is used to define common fields for all 3 stream structs. Accessing
the common fields is hard if you want to be independent from the stream
type.
Introduce an actual generic stream struct (struct sh_stream), which is
supposed to unify all 3 stream types one day. Once all fields defined
by SH_COMMON have been moved into sh_stream, the transition is complete.
Move some fields into sh_stream, and rewrite osd_show_tracks to use
them.
Generally enable parsing for audio streams.
The formats I know of that do not need it (e.g. raw audio) do
not have a parser anyway.

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.
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
Including <malloc.h>, especially if all you want is malloc(), has no
legitimate uses (on sane platforms at least). Remove the check for it,
and remove all uses in the code.
Remove unused check for alloca().
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()).
When playing a file, users (i.e. me) expect mplayer to print a list of
video/audio/subtitle streams. Currently, this is done in each demuxer
separately. This also means the output is formatted differently
depending which demuxer is active.
Add code to print an uniformly formatted streams list in the player
front end. Extend the streams headers to export additional information
about the streams. Change the lavf and mkv demuxers to follow this new
scheme, and raise the log level for the "old" printing functions.
The intention is to make every demuxer behave like this eventually.
The stream list output attempts to provide codec information. It's a
bit hacky and doesn't always provide useful output, and I'm not sure
how to do it better.
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.
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.
