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.

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.

Change libavcodec subtitle decoding code (used for some bitmap

Remove the following #defines, which should never change in practice:
CONFIG_FAKE_MONO, OUTBURST, FAST_OSD, FAST_OSD_TABLE
The configure script hardcoded these to particular values in config.h.
They could only be changed by manually editing it. I don't think
anyone would want to.

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.
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.
Remove the duplicated list of audio format names from m_option.c. Remove
"long" audio format names, and let af_fmt2str() print the usual short
format names. The long names were overly verbose, and were actually
rarely user visible. The only difference between af_fmt2str() and
af_fmt2str_short() is that the former prints unknown format values as
hexadecimal string as fallback.
Remove the duplication of image format name lists from codec-cfg.c
and img_format.c. Remove the list of "long" image format names from
img_format.c.
One user visible change is that now mplayer won't print "long" format
names anymore: e.g. instead of "Planar 420P 10-bit little-endian",
the name "420p10le" is used. This is consistent with the names used
by the option parser, and also less noisy.
Partially based on mplayer2 commit f98e47574de15, with some differences.
Make the conditional hiding logic introduced in commit 3259e4a7a2a938
("cocoa_common: make fullscreen menubar/dock hiding conditional") work
when mplayer is started with the `fs` and `xineramascreen` options.
The osd_show_progression command ('P' key) created text similar to
what --osdlevel=3 shows, and set that as an OSD message. This message
was static and wasn't updated while visible, even if video position
changed (very noticeable during fast forward, when real OSD position
changes rapidly). Instead of setting a static message, create a new
message type that makes the OSD update code behave as if osd level was
set to 3 for the duration of the message.
The OSD progress bar isn't updated while the message is active.
Based on mplayer2 commit 458001463b2252fc by uau.
This crash happened when audio channels were reconfigured from 6
channels to 2, and playback speed was set to 2.
The crash is caused by passing a negative size to memcpy. It appears
reinitialization doesn't clear the buffer. As the result, the buffer
can be larger as the maximum buffer size, i.e. the invariant
bytes_queued <= bytes_queue is violated.
Fix this by resetting the buffer length on reconfiguring (set the
bytes_queued vairable to 0). Also reset some other state for clarity
and robustness, although these changes aren't strictly needed for
avoiding the actual crash.
This may also get rid of some noise played right after reinitialization,
as the re-used buffer was in the wrong audio format.
Enabling optimization _still_ causes annoyances when using a debugger,
and it increaes compilation times too.
Now --enable-debug basically replaces the -O2 flag with -g.
Remove printing VO modules that were removed earlier, but were enabled
by configure tests that are still needed.
Print "libavcodecs" with the "Codecs: " output.
Add a flags parameter to mp_input_set_section(). Add a flag that defines
whether bindings in the default section are used or not. This is useful
for special functionality, where the normal key bindings may have
unwanted effects.
For example, it shouldn't be possible to seek during encoding. However,
you want to be able to cancel the encoding process gracefully. For that
purpose, the "encode" section of input.conf could be made exclusive:
mp_input_set_section(mpctx->input, "encode", MP_INPUT_NO_DEFAULT_SECTION);
And input.conf could contain this definition:
RIGHT seek 10
q {encode} quit
Then only the key "q" would be bound during encoding.
