Extend m_properties_expand_string() so that it can print properties as
unformatted string. Normally, properties will be pretty-printed
(intended for OSD and user interface purposes). Add the '=' modifier to
the format string syntax that disables pretty-printing and returns them
"raw".
For example, "${=switch_audio}" will print the track number, instead of
returning an OSD friendly string containing additional information like
track title and language.
This is done by requesting a buffer from the next filter in the chain, instead
of always allocating our own. This allows the next filter to e.g. ensure its
own preferred memory layout.
Normally, video/audio/sub track selection is persistent across files
played in the same mplayer instance. This is wanted, because settings
should not be reset across files in general. However, if the track
layout of a file is completely different from the previous, this will
essentially select random tracks. In this case, keeping the track
selection is confusing and unwanted.
Reset the track selection to default if the track layout changes. The
track layout is determined by number of tracks, track order, default
flag, whether the track is an external subtitle, and track language.
If a track layout change is detected when playing a new file, the -sid,
-aid and -vid options are reset to "auto".
This behavior is enabled only if the user selects tracks manually (via
keybinds and the "switch_audio" slave properties etc.). If no user
interactions take place, options specified on the command line will
follow the old behavior.
This is needed by demux_mpg (and possibly by demux_ts) for PCM playback.
The decoder does the mapping from MPEG headers to the actual PCM format,
and also unpacks sample data for 20/24 bit formats.
Previously, Matroska source files other than the initially opened one
were always accessed without caching. Enable cache for extra files
too. A separate cache process/thread is started for each file, which
is less than optimal but probably better than no caching if the user
explicitly enabled cache. This commit only implements caching for
Matroska ordered chapters (not for EDL timeline).
To build the timeline we need to demux the files in the current
directory to look for segments with matching uuid. This first demux is
done with no cache since we don't need to read a lot of the stream. If
the file is recognized as one of the needed sources it's reopened with
cache enabled.
Also move the stream_cache_size global variable to the options struct.

Support passing bitmap subtitles to VOs in full RGBA color, and
implement this for libavcodec-decoded subtitle formats on decoding
side and vo_vdpau on display side. Currently this is enabled for PGS
(blu-ray) and DVB subtitles.
VDPAU seems to have sampling issues similar to known GL ones when
drawing a sub-rectangle from a larger texture with scaling, where
adjacent pixels outside the specified source rectangle affect the
result. As the bitmap subtitles may be scaled, add padding support to
the bitmap packer code.
In principle, this could be used for colored DVD subtitles too.
However, the libavcodec DVD decoder lacks parts of the resolution and
palette handling that are present in spudec.c.

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 --vid, --aid, --sid options now accept the values 'off' and 'auto',
instead of having the user deal with the numeric values -2 and -1. The
numeric values are not allowed anymore.
Remove the --audio option. It was probably meant as compensation option
for --no-audio. There are no such options for sub/video, and it was not
documented, so just remove it. The replacement is "--aid=auto".
Also do some updates to the manpage.
The --loop option takes slightly different parameters now. --loop=0
used to mean looping forever. Now it means looping is disabled (this is
more logical: 2 means playing 2 more times, 1 means playing 1 more time,
and 0 should mean playing not again).
Now --loop=inf must be used to enable looping forever.
Extend choice types to allow an optional range of integers as values.
If CONF_RANGE is added to the flags of a m_option_type_choice option,
m_option.min/max specify a range of allowed integer values. This can be
used to remove "special" values from make integer range options. These
special values are unintuitive, and sometimes expose mplayer internals
to the user. The (internal) choice values can be freely mixed with the
specified integer value range. If there are overlaps, the choice values
are preferred for conversion to/from strings.
Also make sure the extension to choice options works with properties.
Add the ability to step choice properties downwards, instead of just
upwards.
This was to make an option without value use the option's default value
(e.g. --term-osd is the same as --term-osd=auto). Make it simpler by
handling this case as an empty choice.
The flag was probably needed when option handling still did ambiguous
argument parsing.
It can't be re-implemented, because this isn't supported by libass. The
-subalign option and the associated sub-align slave property did
nothing. Remove them.
Handling this was accidentally forgotten when command line parsing was
refactored. The added recursive call should be a tail recursion with
all reasonable compilers, and it shouldn't be possible to provoke a
stack overflow.
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.)
No decoder actually used this value (except ad_acm, which was removed a
while ago), so this change shouldn't have any bad consequences.
ad_ffmpeg passes wf to libavcodec decoders, but only the extra data
portion.
This change is needed by the next commit.
This was removed in commit 6a26b4a665. Add it back, because it was
needed by demuxer_rawaudio and for PCM audio with demuxers other than
demux_lavf. (In practice, this broke rawaudio and PCM-in-Matroska only.)
Unlike with raw video, there is no single raw audio "decoder" in
libavcodec. Instead of trying to mess raw audio input into ad_ffmpeg
using a table to map audio formats to the respective libavcodec
decoders, it seems advantageous to simply add back ad_pcm.
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.
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.
Remove VESA and FBDEV specific code that was forgotten when the
respective VOs were removed. Remove references to old or broken
stuff from example.conf.
This was destroyed by Uoti Urpala in commit "subs: always use sub...".
Features should be either kept working or completely removed, but not
just crippled, which only inflates the code and frustrates users.
vo_vdpau and vo_gl cache the last subtitle bitmaps uploaded to video
card in case they stay the same over multiple frames. Detecting
whether the bitmaps have changed and should be re-uploaded was
somewhat fragile. Change the VO API to provide a bitmap ID which can
be compared with what the VO has to determine whether a new upload of
the bitmaps is needed.
Conflicts:
libvo/vo_gl.c
Note: the changes for vo_gl.c were not merged. Instead, eosd_packer is
modified to use the new way of detecting EOSD changes. This takes care
of vo_gl, vo_gl3 and vo_direct3d, which all render EOSD. They don't
need to be updated in turn.
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.

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.
Remove subtitle selection code setting osd->ass_track directly and
vf_ass/vf_vo code rendering the track directly with libass. Instead,
do track selection and rendering with dec_sub.c functions.
Before, mpctx->set_of_ass_tracks[] contained bare libass tracks
generated from external subtitle files. For use with dec_sub.c, it now
contains struct sh_sub instances with decoder already initialized.
This commit breaks the sub_step command ('g' and 'y' keys) for
libass-rendered subtitles. It could be fixed, but it's so useless -
especially as with the existing implementation there's no practical
way to get subtitle delay back to normal after using it - that I
didn't bother.
Conflicts:
command.c

To draw libass subtitles, the code used ASS_Renderer objects created
in vf_vo (VO rendering) or vf_ass. They were destroyed and recreated
together with the video filter chain. Change the code to use a single
persistent renderer instance stored in the main osd_state struct.
Because libass seems to misbehave if fonts are changed while a
renderer exists (even if ass_set_fonts() is called on the renderer
afterwards), the renderer is recreated after adding embedded fonts.
The known benefits are simpler code and avoiding delays when switching
between timeline parts from different files (libass fontconfig
initialization, needed when creating a new renderer, can take a long
time in some cases; switching between files rebuilds the video filter
chain, and this required recreating the renderers). On the other hand,
I'm not sure whether this could cause inefficient bitmap caching in
libass; explicitly resetting the renderer in some cases could be
beneficial. The new code does not keep the distinction of separate
renderers for vsfilter munged aspect vs normal; this means that
changing subtitle tracks can lose cache for the previous track.
The new code always sets some libass parameters on each rendering
call, which were previously only set if they had potentially changed.
This should be harmless as libass itself has checks to see if the
values differ from previous ones.

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.
When switching editions, it would be nice to display an OSD message to
notify the user which edition is being played. This would be consistent
with visual feedback like on tracking switching, seeking, and so on.
Rather than introducing awkward hacks and special cases to determine
whether a file is being "restarted" (as it happens on edition switching)
to avoid clearing the OSD messages, simply never clear the OSD stack.
This is more consistent with handling of OSD bars too: they didn't
disappear when going to a new file (especially noticable when seeking
past the end of the file).
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.
Usually failing to initialize the video chain does not stop playback,
and continues with audio-only. But when VF/VO config failed (the second
step in initializing them), playback was canceled and advanced to the
next file.
Make it more consistent and just switch off video if it fails.
Also, if no audio track is selected, go to next file anyway. The player
core goes into some sort of idle mode if no video and audio track is
selected, and we don't want to trigger it here. (It's unclear whether
that is a bug or feature: it's meant to work around some corner cases,
but maybe it shouldn't be triggered when switching off video & audio
tracks in normal playback.)
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.
Whenever the demuxer is accessed to retrieve metadata, use the newly
introduced master_demuxer field instead. If a timeline is used, the
master_demuxer will still refer to the main file, instead to segments.
Instead of mpctx->demuxer->stream, access mpctx->stream; even though
they are the same, the code becomes shorter. For the TV code, introduce
a function get_tvh() to access the TV handle, instead of duplicating the
code all over the place. Often the demuxer field is checked to determine
whether something is currently played; prefer other methods over that.
Note that the code before always accessed the current timeline segment,
and would e.g. read file metadata of the current segment. Now it always
returns metadata for the master file. This may have various wanted and
unwanted effects.
This messes deeply with the subtitle bookkeeping data structures, and
would have to be reimplemented anyway.
It's not sure what this was even useful for. Possibly for slave mode.
The timeline code kept pairs of stream and demuxer references around.
The reference to the stream is redundant, because it can be accessed
through the demuxer.
Simplify the code by removing the redundant stream reference.
Also, set mpctx->stream to the current segment when using timeline.
Fix a small memory leak in tl_matroska.c introduced earlier.
The code for showing OSD progression ('P' key) set a flag in a
mp_osd_msg_t to do its work. OSD messages can be re-used for completely
unrelated purposes (it's unclear why), so this has to be reset if an
old OSD progression message is reused for something different.
Be sure to reset the full message. Remove the messy code for searching
the OSD stack. Use the existing rm_osd_msg() function to remove the old
message (if there was one), and always create a new message. The new
code should be functionally equivalent to the old code. The "started"
flag wasn't reset before, but since the time is always overwritten, this
might be actually more correct.
