This also requires that the OSD stack related functions carry a pointer
to MPContext.
Free the OSD stack items (mp_osd_msg) at exit by making MPContext the
talloc parent. (E.g. when exiting while something is still displayed on
the OSD.)

The only place exit_player() should be called is the main() function.
exit_player() should be the only function allowed to call exit(). This
makes it easier to guarantee proper deinitialization, and allows using
the --leak-report flag without showing false positives.
The quit slave command now sets a flag only. It uses the same mechanism
that's normally used to advance to the next file on the playlist, so the
rest of the playback path should be able to react to the quit command
quickly enough. That is, the player should react just as fast to quit
requests in practice as before this commit.
In reinit_audio_chain(), the player was actually exited if
init_audio_filters() failed. Reuse the normal error handling path to
handle this condition.

This is a regression introduced by commit 9c02ae7e95108.

Other (newer) parts of mplayer use this convention, so don't introduce
new conventions.

The print_timeline() function actually had contained some code that
changed the MPContext state. Since you wouldn't expect that from a
function named print, move that code out of the function. The
misleading code structure was introduced in commit 6f564fe82b.

Commit 89a17bcda6c16 simplified the idle loop to run any commands
mplayer receives, not just playlist related commands. Unfortunately, it
turns out many slave commands always assume the presence of a demuxer.
MPContext->demuxer is assumed not to be NULL. This made the player
crash when receiving slave commands like pause/unpause, chapter
control, subtitle selection.
We want mplayer being able to handle this. Any slave command or
property, as long as it's backed by a persistent setting, should be run
successfully, even if no file is being played. If the slave command
doesn't make sense in this state, it shouldn't crash the player.
Insert some NULL checks when accessing demuxers. If sh_video or
sh_audio are not NULL, assume demuxer can't be NULL.
(There actually aren't that many properties which need to be changed. If
it gets too complicated, we could employ alternative mechanisms instead,
such as explicitly marking safe properties with a flag.)

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.
|
| |
|
|
|
|
|
| |
The SH_COMMON lang field seems to be blatantly unreliable and is not
always set by demux_lavf (at least not with dvdnav:// ).
Also fix the same for the show_tracks_osd slave command.

The structure is now as follows:
- main():
* basic initializations (e.g. init_libav() and more)
* pre-parse command line (verbosity level, config file locations)
* load config files (parse_cfgfiles())
* parse command line, add files from the command line to playlist
(m_config_parse_mp_command_line())
* call:
- handle_help_options():
* check each help-related option
* print help if requested
* main() exits if help was requested
* call function that works down the playlist:
- play_files():
* run idle loop (idle_loop()), until there are files in the
playlist or an exit command was given (slave mode only)
* actually load and play a file:
- play_current_file():
* run all the dozens of functions to load the file
and initialize playback
* run a small loop that does normal playback, until
the file is done or a slave command terminates
playback
(each iteration, run_playloop() is called)
* uninitialize playback
* determine next entry on the playlist to play
* loop
* call exit_player_with_rc() (there are many other places which
use this function, though)

The main() function used to be way too big, to the point that it was
unreadable (> 1000 lines).
Move random parts out of the main into new functions.

This is about the vo_x11_init_state() call. It basically opens a X11
connection. It's called in the main() function once. It's not really
clear why this isn't done on VO creation instead. Maybe one reason was
that --no-fixed-vo used to be the default: when playing a new file, the
full VO state would be free'd and recreated. Keeping the X11 connection
possibly improved things, although the question is how. In summary,
there is no good reason to do this, and it only adds platform specific
details to the player frontend.
Do the X11 initialization in the respective VOs instead.

The intention is to make the main() function smaller (which is at
about 1000 lines currently).
This commit also changes the order of some initializations, but that
should be safe.
|
| |
|
|
| |
It's not clear why that was done in mplayer's main function.

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.

The --title option, which sets the GUI window caption, is now expanded
as slave mode property string (like osd_show_property_text). Make the
default value for --title include the filename. This makes a behavior
similar to --use-filename-title the default.
Remove the --use-filename-title option, as it's redundant now.

vo_osd_changed() was a weird function: it was used both to query and
mutate state, which is a bad combination. The VOs used it to query
and reset the state, and the mplayer frontend mostly used it to set
the state. In some cases, the frontend did both (that code used a
variable "int hack" to backup the state and set it again).
Simplify it and make the VOs use a vo_osd_has_changed() function to
query whether the OSD bitmaps have to be recreated. vo_osd_changed()
on the other hand is now used to update state only. The OSD change
state is reset when osd_draw_text() is called.
Update vo_corevideo.m to use vo_osd_resized() as well (forgotten change
from libass-OSD merge).
Simplify osd_set_text() and its usages.

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.

The code to format the playback time was duplicated a few times. There
were also minor differences in how the time is formatted. Remove most
of these differences. This also fixes a bug in the output of the
osd_show_progression command, introduced in 74e7a1e937c10d9f4.
There was some logic to display the percent position in the OSD status
for a short while after seeking. Remove that logic and always display
the percent position.
Make --osd-fractions a flag option. This removes the ability to show
the number of frames played since the start of the current second
(i.e. the fraction of the time was turned into a frame number). This
features wasn't so great anyway, because modern video file formats
don't always have a (valid) FPS set, and could lead to inaccurate
display.
Still to sort out:
Unfortunately, the terminal status is still formatted differently from
the OSD, and even worse, it has a completely different time source.
Not sure if I like how the status line looks now (it's a bit "full"?).
Maybe it will be changed again later.

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.

This was intended for translating filenames from filesystem charset to
the terminal charset. Modern sane platforms use UTF-8 for everything,
and on Windows we use unicode APIs, so this is not needed anymore.
Remove filename_recode, all uses of it, options and configure checks
related to terminal output charset, and code that tries to determine
the same.

This had very limited usefulness, and you're much better off using
ffmpeg directly. Even if that should not be sufficient, the mplayer
encoding branch might provide a better way out.

Pausing the player used to print the message "===== PAUSE =====". It
also inserted a newline for some reason. When pausing and unpausing a
lot, the terminal would be clobbered with "old" useless status lines.
Remove the pause message, and display the status message instead. This
looks better, doesn't fill up the terminal with crap, and needs less
code.
Side note: when cache is enabled, the status line is reprinted on every
idle iteration to reflect possible cache changes. If the platform's
WAKEUP_PERIOD is very small (like on Windows) and terminal output is
slow (like on Windows), it's possible that this leads to a minor
performance degradation. This is probably not a problem (and I don't
care anyway), but maybe something that should be kept in mind.
Disabling the status line with --quiet will help.

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()).

Instead of displaying audio and video separately, there's now one
position printed. The idea is that displaying both audio and video
position is redundant. The A/V synchronisation is still printed, so
that you can see if the video time is off.
Also, always print the duration of the file, not only when playing
audio only.
Print "ct" (average A/V sync change) and the number of dropped frame
only if they're significant.
Remove output of outdated and crapified things, like frame position
(these can't be reasonably done with modern media formats, and the
playback code paths for these don't touch them).
This will break some slave mode applications, because they attempt to
parse the status line.

The code used for benchmarking and showing CPU stats in the status line
was inaccurate, misleading and fragile. The final nail in the coffin is
the fact that many libav decoders are multithreaded now, and mplayer
couldn't possibly measure the CPU time consumed by them.
Add the --untimed option. This makes the video untimed, just like
--benchmark did (still requires disabling audio synchronization).

The msg level for the version output is elevated to verbose. When
running mplayer without arguments, the version is printed a second
time (with default msg level) before the help output.

using slave mode.

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.

This used /dev/rtc for timing. /dev/rtc root only by default, and I
have a hard time believing that the standard OS functions are not good
enough. (Even if not, support for POSIX high resolution timers should
be added instead, see clock_gettime() and others.)

mplayer tries to catch all signals by default, and displays a "nice"
crash message if a signal is caught. This is mostly useless for
diagnosing problems, and it's extremely fragile. It's likely to cause
more harm than it possibly solves.
Also remove the current_module variable, which was supposed to give a
hint which submodule was being run. This was far from accurate or
useful.
mplayer also caught SIG_CHILD, and tried to wait for any children. This
potentially gets rid of zombies, but I'm not sure which ones. The only
places that fork(), cache2.c and unrar_exec.c, seem to wait for their
child processes properly. Just get rid of it.
Note that we don't even catch SIGTERM. Maybe this will have to be added
back in order to re-enable screensavers and such when the user
terminates mplayer with ^C on the terminal.

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.
