Unfortunately, merely changing the playlist current position affects the
flags returned by the "playlist" property, so the entirely thing needs
to be marked as changed. Seems to be a design mistake.
Should give a good deal more explicit control and insight over the
player state.
Some feel a bit pointless, and/or expose internal weirdness. However,
it's not like the existing weirdness didn't exist before, or can be made
go away. (In part, the weirdness is because certain in-between states
are visible. Hiding them would make things simpler, but less flexible.)
Maybe this actually gives users a better idea how the API _should_ look
like, too.
On a side note, this tries to really guarantee that mpctx->playing is
set between playback start/end. For that, the loadfile.c changes assume
that mpctx->playing is set (guaranteed by code above the change), and
that playing->filename is set (probably could never be false; was broken
before and actually would have crashed if that could ever happen; in any
case, also add an assert to playlist.c for this).
playlist_entry_to_index() now tolerates playlist_entrys that are not
part of the playlist. This is also needed for mpctx->playing.
It's odd that this state is observable, but is made implicit by making
the property unavailable. It's also odd that an API user cannot directly
put the player into such a state.
Just allow reading/writing -1 (or in fact, any out of bounds index) for
this case.
I'm also refraining from using OPT_CHOICE for the "no selection" case,
because although that would be cleaner in theory, it would cause only
problems to API users due to the more complex property type (worse is
better).
One reason for not restricting the integer range on the input property
anymore is that if there are no playlist elements, the range would
contain only 1 integer, which cannot be represented anymore since the
recent m_option change. This was actually broken with 1 element
playlists before (and still is, with the constricted type for OSD and
the add/cycle commands). Doesn't matter too much.
If the user manages to run a "loadfile x append" command before the loop
in mp_play_files() is entered, then the player could start playing
these. This isn't expected, because appending files to the playlist in
idle mode does not normally start playback. It could happen because
there is a short time window where commands are processed before the
loop is entered (such as running the command when a script is loaded).
The idle mode semantics are pretty weird: if files were provided in
advance (on the command line), then these should be played immediately.
But if idle mode was already entered, and something is appended to the
playlist using "append", i.e. without explicitly triggering playback,
then it should remain in idle mode.
Try to follow this by redefining PT_STOP to strictly mean idle mode.
Remove the playlist->current check from idle_loop(), since only the
stop_play field counts now (cf. what mp_set_playlist_entry() does).
This actually introduces the possibility that playlist->current, and
with it playlist-pos, are set to something, even though playback is not
active or being started. Previously, this was only possible during state
transitions, such as when changing playlist entries.
Very annoyingly, this means the current way MPV_EVENT_IDLE was sent
doesn't work anymore. Logically, idle mode can be "active" even if
idle_loop() was not entered yet (between the time after mp_initialize()
and before the loop in mp_play_files()). Instead of worrying about this,
redo the "idle-active" property, and deprecate the event.
See: #7543
What was this even for? Also, most times, the cleared status line will
show up as an empty new line anyway, so this commit reduces the empty
new lines from 2 to 1.
The code that determines the process exit code ignores all stop_play
values other than PT_QUIT. Generally, PT_ERROR is meaningless outside of
play_current_file(), and is mostly equivalent to PT_NEXT_ENTRY.
Do something that makes it report a non-0 exit code, and indicates in
the terminal exit message that something went wrong.
Untested.
Using mpv without libass isn't really supported, since it's not only
used to display ASS subtitles, but all text subtitles, and even OSD.
At least 1 user complained that the player printed a warning if built
without libass. Avoid trying to create the impression that using this
software without libass is in any way supported or desirable, and make
it fully mandatory.
(As far as making dependencies optional goes, I'd rather make ffmpeg
optional, which is an oversized and bloated library, rather than
something tiny like libass.)
Change all OPT_* macros such that they don't define the entire m_option
initializer, and instead expand only to a part of it, which sets certain
fields. This requires changing almost every option declaration, because
they all use these macros. A declaration now always starts with
{"name", ...
followed by designated initializers only (possibly wrapped in macros).
The OPT_* macros now initialize the .offset and .type fields only,
sometimes also .priv and others.
I think this change makes the option macros less tricky. The old code
had to stuff everything into macro arguments (and attempted to allow
setting arbitrary fields by letting the user pass designated
initializers in the vararg parts). Some of this was made messy due to
C99 and C11 not allowing 0-sized varargs with ',' removal. It's also
possible that this change is pointless, other than cosmetic preferences.
Not too happy about some things. For example, the OPT_CHOICE()
indentation I applied looks a bit ugly.
Much of this change was done with regex search&replace, but some places
required manual editing. In particular, code in "obscure" areas (which I
didn't include in compilation) might be broken now.
In wayland_common.c the author of some option declarations confused the
flags parameter with the default value (though the default value was
also properly set below). I fixed this with this change.
The message_timeout field was basically polled. But ever since the OSC
was changed to work more event based, this didn't quite work. It was
quite visible when switching subtitle or audio tracks while paused (and
with caching disabled, since the cache update triggered some extra
redrawing).
Fix by using a proper timer.
I noticed that changing tracks with the message call commented didn't
redraw properly either, but, uh, I guess the message is always triggered
anyway, and happens to take care of this.
The option code is very old and was added to MPlayer in the early 2000s,
when C99 was still new. MPlayer did not use the "bool" type anywhere,l
and the logical option equivalent to bool, the "flag" option type, used
int, with the convention that only the values 0 and 1 are allowed.
mpv may have hammered many, many additional tentacles to the option
code, but some of the basics never changed, and m_option_type_flag still
uses int. This seems a bit weird, since mpv uses bool for booleans. So
finally introduce an m_option_type_bool. To avoid duplicating too much
code, change the flag code to bool, and "reimplement" m_option_type_flag
on top of m_option_type_bool.
As a "demonstration", change the --fullscreen option to this new type.
Ideally, all options would be changed too bool, and m_option_type_flag
would be removed. But that is a lot of monotonous thankless work, so I'm
not doing it, and making it a painful years long transition.
At the same time, I'm introducing a new concept for option declarations.
Instead of OPT_BOOL(), which define the full m_option struct contents,
there's OPTF_BOOL(), which only takes the option field name itself. The
name is provided via a normal struct field initializer. Other fields
(such as flags) can be provided via designated initializers.
The advantage of this is that we don't need tons of nested vararg
macros. We also don't need to deal with 0-sized varargs being a pain
(and in fact they are not a thing in standard C99 and probably C11).
There is no need to provide a mandatory flags argument either, which is
the reason why so many OPT_ macros are used with a "0" argument. (The
flag argument seems to confuse other developers; they either don't
immediately recognize what it is, and sometimes it's supposed to be the
option's default value.)
Not having to mess with the flag argument in such option macros is also
a reason for the removal of M_OPT_RANGE etc., for the better or worse.
The only place that special-cased the _flag option type was in
command.c; change it to use something effectively very similar that
automatically includes the new _bool option type. Everything else should
be transparent to the change. The fullscreen option change should be
transparent too, as C99 bool is basically an integer type that is
clamped to 0/1 (except in Swift, Swift sucks).
Commit 8d965a1bfb changed option/property min/max handling. As a
consequence, ranges that contain only 1 or 0 elements are not possible
anymore. Normally that's fine, because it makes no sense to have an
option that has only one or none allowed value (statically).
But edition switching used some sort of mechanism where the property can
return a different, dynamically decided range at runtime. That meant
that if there were <2 editions, edition switching with the "cycle"
command would always pick the same value. But with the recent commit,
this changed to having "no range set" and would cycle through all
integer values.
Work this around with a simple change. Now, edition switching on a file
without editions shows "edition: auto" instead of "edition: 0", which
may appear odd. But the former is the --edition default value, and
previous mpv versions rendered the edition property like this when not
using switching.
(Who the fuck uses editions?)
Before this commit, option declarations used M_OPT_MIN/M_OPT_MAX (and
some other identifiers based on these) to signal whether an option had
min/max values. Remove these flags, and make it use a range implicitly
on the condition if min<max is true.
This requires care in all cases when only M_OPT_MIN or M_OPT_MAX were
set (instead of both). Generally, the commit replaces all these
instances with using DBL_MAX/DBL_MIN for the "unset" part of the range.
This also happens to fix some cases where you could pass over-large
values to integer options, which were silently truncated, but now cause
an error.
This commit has some higher potential for regressions.
Move the "old" mostly command line parsing and option management related
code to m_config_frontend.c/h. Move the the code that enables other part
of the player to access options to m_config_core.c/h. "frontend" is out
of lack of creativity for a better name.
Unfortunately, the separation isn't quite clean yet. m_config_frontend.c
still references some m_config_core.c implementation details, and
m_config_new() is even left in m_config_core.c for now. There some odd
functions that should be removed as well (marked as "Bad functions").
Fixing these things requires more changes and will be done separately.
struct m_config is left with the current name to reduce diff noise.
Also, since there are a _lot_ source files that include m_config.h, add
a replacement m_config.h that "redirects" to m_config_core.h.
Really minor detail that doesn't really matter. If frame stepping pauses
playback on end (why does this special case even exist), it should
probably be done after on_unload, because all works is supposed to be
finished at that point.
This was not reset in the num_properties==0 case. This didn't really
matter, but for debugging it's slightly nicer to see new_property_events
reset once the client thread is done with it.
Until now the 'update' method used mp.command_native with a hardcoded
list of key names.
Change it to use whatever keys the user set to this object, so that
we can remain oblivious to new keys which 'osd-overlay' may support.
This is how the lua code did it from the begining. We didn't, and now
we pay the price.
Note: could be implemented either as we have now (clone `this`
excluding the methods) or by moving the methods up the prototype chain
(i.e. class methods) so they don't get enumerated and use `this` as
the command object itself.
However, in the latter approach we'll have to save the values which we
change (name, res_x, res_y) and restore them after the command, so it's
simpler to just clone `this`.
When the current file changes (or rather, when starting/finishing
playback of a playlist entry), clients tend to have the problem that
it's hard to tell whether a property change notification (via
mpv_observe_property() and mechanisms layered on top of it) is from the
previous or new playlist entry. The previous commit probably helps, but
all the asynchronity is still a bit unhelpful.
Try to make this better by adding new hooks, that are run before/after
playback init/deinit. This is similar to the existing hooks, except
they're outside of "initialized" playback, which excludes that you might
accidentally get an overlap between the current and the previous/next
playlist entry.
That still doesn't seem quite enough, since normally, property change
notifications come after the hook event. So basically a client would
have to explicitly "drain" the event queue within the hook, and make the
hook continue only after that is done. Knowing when property
notifications are done is another asynchronous nightmare (how exactly it
works keeps changing within client.c, and an API user probably can't
tell anymore when all pending properties are truly done). So introduce
another guarantee: properties that were changed before the hook happens
will be returned before the hook event is returned. That means the
client will have received all pending property notifications from the
previous playlist entry (or whatever) before the hook is entered.
As another minor complication, we shouldn't just keep the hook pending
until _all_ property notifications are done, since the client's hook
could produce new ones. (Or just consider things like the demuxer thread
hammering the client with cache update events, while the "on_preloaded"
hook is run.) So there is some extra untested, fragile logic in client.c
to handle this (the waiting_for_hook flag).
This probably works, but was barely tested. Not sure if this helps
anyone, but I think it's fine for my own purposes. (I really hated this
aspect of the API whenever I used it myself.)
This could happen if a property was flagged as changed, then updated,
then flagged again, but gen_property_change_event() was called before
the value was updated a second time. Then the function simply returned
the old value, and would later trigger a new change event again.
This was considered acceptable before, since property notifications are
asynchronous anyway (so they may always be "outdated", it just mattered
whether the most recent value was eventually delivered).
But consider ordering with events. It seems desirable that specific
important events (e.g. MPV_EVENT_START_FILE) should not be followed by
property updates that happened before it, because that would make
application logic really a mess, and property notification near-useless
in certain cases.
Avoid this by never returning a value if it was marked changed, but not
updated yet.
Unfortunately, this could lead to clients never receiving a value (or
receiving it with a high random delay), if they're too slow to read it
(or the property simply updates too often). Note that this is done for
_all_ property notifications, not just returned events. Hopefully not a
problem in practice. If it turns out to be one, this mechanism could be
restricted to actually returned events, for which this really matters.
This is more or less a minimal hack to make _some_ text measurement
functionality available to scripts. Since libass does not support such a
thing, this simply uses the bounding box of the rendered text.
This is far from ideal. Problems include:
- using a bitmap bounding box
- additional memory waste and/or flushing caches
- dependency on window size
- odd small deviations with different window sizes (run osd-test.lua and
resize the window after each timer update; the bounding boxes aren't
adjusted in an overly useful way)
- inability to query the size _after_ actual rendering
But I guess it's a start. Since I'm aware that it's crap, add a threat
to the manpage that this may be changed/removed again. For now, I'm
interested whether anyone will have use for it in its current form, as
it's an often requested feature.
When the demuxer cache read until the end of the stream, and was
finished and completely inactive, the cache properties were not updated
anymore via MP_EVENT_CACHE_UPDATE.
Unfortunately, many cache properties depend on the current playback
position, such as cache-duration or fw-bytes. This is especially visible
on the OSC. If everything was cached, seeking around didn't update the
displayed forward cache duration.
That means checking demuxer_reader_state.idle is not enough. You also
need to check whether the current playback position changed.
Fix this by explicitly using the current playback position, and update
the properties if it changed "enough". "Enough" is 1 second of media
time in this example, which may or may not be appropriate.
In general, this could probably be done better. There are many other
triggers that change the cache state and that are not covered. For now
I'm content with getting rid of the obvious problems.
I think the OSC problem in particular was caused by changing it from
polling to using property change notifications.
Some filters may block the playloop for a longer time. For example, if a
decoder fails to decode anything and somehow just discards packets, the
filter graph would run (in a blocking manner) until all packets are
read, which could take a longer time if the demuxer thread is fast
enough.
Make it exit every 100ms. That should at least give the user a chance to
stop playback.
Filtering could run on a different thread, but I don't see much value in
doing that in the general case. It would just waste a thread. Although
being able to use mp_filter_graph_interrupt() would be slightly nicer
than such a timeout mechanism. Decoding in particular can actually use a
separate thread (--vd-queue-enable), but again, this is not enabled by
default, because it just wastes a thread.
Like the previous f_decoder_wrapper commit, this is probably a sin.
Instead of having f_decoder_wrapper create its own copy of the entire
mpv option tree, create a struct local to that file and move all used
options to there.
movie_aspect is used by the "video-aspect" deprecated property code. I
think it's probably better not to remove the property yet, but
fortunately it's easy to work around without needing special handling
for this option or so.
correct_pts is used to prevent use of hr-seek in playloop.c. Ignore
that, if you use --no-correct-pts you're asking for trouble anyway. This
is the only behavior change.
See manpage additions. This has been a topic in MPlayer/mplayer2/mpv
since forever. But since libavcodec multi-threaded decoding was added,
I've always considered this pointless. libavcodec requires you to
"preload" it with packets, and then you can pretty much avoid blocking
on it, if decoding is fast enough.
But in some cases, a decoupled decoder thread _might_ help. Users have
for example come up with cases where decoding video in a separate
process and piping it as raw video to mpv helped. (Or my memory is
false, and it was about vapoursynth filtering, who knows.) So let's just
see whether this helps with anything.
Note that this would have been _much_ easier if libavcodec had an
asynchronous (or rather, non-blocking) API. It could probably have
easily gained that with a small change to its multi-threading code and a
small extension to its API, but I guess not.
Unfortunately, this uglifies f_decoder_wrapper quite a lot. Part of this
is due to annoying corner cases like legacy frame dropping and hardware
decoder state. These could probably be prettified later on.
There is also a change in playloop.c: this is because there is a need to
coordinate playback resets between demuxer thread, decoder thread, and
playback logic. I think this SEEK_BLOCK idea worked out reasonably well.
There are still a number of problems. For example, if the demuxer cache
is full, the decoder thread will simply block hard until the output
queue is full, which interferes with seeking. Could also be improved
later. Hardware decoding will probably die in a fire, because it will
run out of surfaces quickly. We could reduce the queue to size 1...
maybe later. We could update the queue options at runtime easily, but
currently I'm not going to bother.
I could only have put the lavc wrapper itself on a separate thread. But
there is some annoying interaction with EDL and backward playback shit,
and also you would have had to loop demuxer packets through the
playloop, so this sounded less annoying.
The food my mother made for us today was delicious.
Because audio uses the same code, also for audio (even if completely
pointless).
Fixes: #6926
I may (optionally) move decoding to a separate thread in a future
change. It's a bit attractive to move the entire decoder wrapper to
there, so if the demuxer has a new packet, it doesn't have to wake up
the main thread, and can directly wake up the decoder. (Although that's
bullshit, since there's a queue in between, and libavcodec's
multi-threaded decoding plays cross-threads ping pong with packets
anyway. On the other hand, the main thread would still have to shuffle
the packets around, so whatever, just seems like better design.)
As preparation, there shouldn't be any mutable state exposed by the
wrapper. But there's still a large number of corner-caseish crap, so
just use setters/getters for them. This recorder thing will inherently
not work, so it'll have to be disabled if threads are used.
This is a bit painful, but probably still the right thing. Like
speculatively pulling teeth.
This was a hack that attempted to line up external audio tracks with
video. The problem is that if you do a keyframe seek backwards, video
will usually seek much farther back than audio (due to much higher
keyframe aka seek point distances). The hack somehow made seeking a 2
step process.
This existed in 4 different forms in the history of this code base, and
it was always very cumbersome. We mostly needed this for ytdl_hook (I
think?), which uses the 4th form, which is nicely confined to
demux_timeline and is unrelated to the "external" audio tracks in the
high level player.
Since this is (probably) not really widely needed anymore, get rid of
it. Better do this now, than when somehow rewriting all the seeking code
(which might happen in this decade or the next or so) and when it
wouldn't be easily revertable anymore in case we find we "really" need
it unlike expected.
There is no issue if hr-seeks are used. Also, you can still use edl
files to "bundle" multiple streams as if it was a single stream (this is
what ytdl_hook does now).
The "seekbarkeyframes" option is now interpreted such if it's true, the
player default is used. Too lazy to make this a choice option or
whatever; the Lua option parser doesn't have support for that anyway.
Someone who cares can adjust this.
Try to deal with various corner cases. But when I fix one thing, another
thing breaks. (And it's 50/50 whether I find the breakage immediately or
a few months later.) So results may vary.
The default for--hr-seek is changed to "default" (not creative enough to
find a better name). In this mode, audio seeking is exact if there is no
video, or if the video has only a single frame. This change is actually
pretty dumb, since audio frames are usually small enough that exact
seeking does not really add much. But it gets rid of some weird special
cases.
Internally, the most important change is that is_coverart and is_sparse
handling is merged. is_sparse was originally just a special case for
weird .ts streams that have the corresponding low-level flag set. The
idea is that they're pretty similar anyway, so this would reduce the
number of corner cases. But I'm not sure if this doesn't break the
original intended use case for it (I don't have a sample anyway).
This changes last-frame handling, and respects the duration of the last
frame only if audio is disabled. This is mostly "coincidental" due to
the need to make seeking past EOF trigger player exit, and is caused by
setting STATUS_EOF early. On the other hand, this might have been this
way before (see removed chunk close to it).
This tries to fix#7206 (hr-seeking past EOF does not stop playback)
again. Commit 57fbc9cd76 should have fixed this, but trying it again
(using that git revision), it often did not work. Whatever the fuck.
So add another dumb special case that will break within weeks. Note that
the check in handle_eof() had no effect, since execute_queued_seek() is
called later, which cancels EOF in the same case.
Hr-seek past the last frame instantly enters EOF, which means
handle_playback_time() will not set playback_pts to the video PTS (as
all video frames are skipped), which leads to the playback time being
taken from the last seek target. This results in confusing behavior,
especially since the seek time will be clipped to the file duration for
display, but not for further relative seeks.
Obviously, the time should be set to the last video frame, so use the
last video frame as fallback if both audio and video have ended. Also,
since the same problem exists with audio-only playback, add a fallback
for audio PTS too. We don't know which was the "last" fragment of media
played (to decide whether to use the audio or video PTS as the
fallback), but it doesn't matter since the maximum works.
This could lead to some undesired effects. In particular the audio PTS
is basically a bad guess, and is for example not clipped against --end.
(But the ridiculous way audio syncing and clamping currently works, I'm
not going to touch that shit unless I rewrite it completely.) The cover
art case is slightly broken: using --keep-open with keyframe seeks will
result in 0 as playback PTS (the video PTS). OK, who cares, it got late.
Also casually get rid of last_vo_pts, since that barely made any sense
at all.
Fixes: #7487
The seeking logic saves the last video frame it has seen (for example
for being able to seek to the last frame, or backstepping).
Unfortunately, the frame was fed back to the filtering pipeline in
situations when it shouldn't have. Then it's an out of order frame,
because it really saves the last _discarded_ frame.
For example, seeking to the end of a file with --keep-open, shift+up,
shift+down => invalid video pts warning due to saved_frame being fed
back.
Explicitly discard saved_frame when it's obviously not needed anymore.
The removed accesses to "r" are strictly speaking unrelated (just
const-propagating them).
args->client was deallocated if the FDs were closed and nothing
referenced it (IPC socket codes detected the closed sockets and
asynchronously killed the mpv_handle in args->client). The problem was
that args->log depended on it, and was also destroyed.
Fix this by duplicating the mp_log.
The relatively recently added property update code has a race condition
when clients exit. It still tried to access mpv_handle during and after
it was destroyed.
The reason is that it unlocks the lock for the mpv_handle list (while
mpv_handle is locked), but nothing in mp_destroy_client() cares about
this case. The latter function locks mpv_handle only before/while it
makes sure all of its activity is coming to an end, such as asynchronous
requests, and property updates that are in progress. It did not include
the case when mp_client_send_property_changes() was still calling
send_client_property_changes() with mpv_handle locked.
Fix this by checking the mpv_handle.destroying field. This field can be
set only when mpv_handle is locked. While we're checking the lock, the
mpv_handle list is still locked, so at worst we might be at the point
before mp_destroy_client() locks the list again and finally destroys the
mpv_handle.
This is a hard to reproduce race condition which I spotted only once in
valgrind by chance, so the fix is unconfirmed.
This was obviously nonsense. In Lua 5.1 this appeared to work correctly,
but it really turned "\." into "." (making the pattern accept any
character). The proper way is using "%" for escaping.
In all_formats mode, we've ignored what --ytdl-format did so far, since
we've converted the full format list, instead of just the formats
selected by youtube-dl.
But we can easily restore --ytdl-format behavior: just mark the selected
tracks as default tracks.
vbr and abr are the video and audio bitrates. Sometimes there is a weird
mix of any of them available, but in these cases, it's not good to fall
back to tbr if a specific track has no vbr/abr.
For example, the alphabetic site provides tbr only for the muxed
fallback stream, but using tbr would make the primitive mpv hls_bitrate
selection pick the compatibility stream for audio, because it appears to
have a higher bitrate than the other audio-only streams (because the
bitrate includes video). So we must not use tbr in this case.
On the other hand, formats coming from youtube-dl HLS master playlist
use will only have tbr set.
So as a heuristic, use the tbr only if it's the only bitrate available
in any track entry.
I don't think the skip_muxed option was overlay useful. While it was
nice to filter out the low quality muxed versions (as it happens on the
alphabetic site, I suspect it's compatibility stuff), it's not really
necessary, and just makes for another tricky and rarely used
configuration option. (This was different before muxed tracks were also
delay-loaded, and including the muxed versions slowed down loading.)
Add the force_all_formats option instead, which handles the HLS case.
Set it to true because they are also delay-loaded now, and don't slow
down startup as much.
If all streams were delay loaded, there was actually no duration present
at all in the EDL metadata. So the length was considered unknown by the
player frontend.
See manpage additions. We would have to extend delay_open to support
multiple sub-tracks (for audio and video), and we'd still don't know (?)
whether it might contain more than one stream each (thinking of HLS
master streams). And if it's a true interleaved file (such as a "normal"
mp4 file provided as fallback for more primitive players), we'd either
have to signal such "bundled" tracks, or waste bandwidth.
This restructures a lot. The if/else tree in add_single_video for format
selection was a bit annoying, so it's split into separate if blocks,
where it checks each time whether a URL was determined yet.
If a "format" has both audio and video codec set, it might contain both
audio and video. all_format assumes that each format is just a quality
variant containing a single track.
This seems to happen with sites that provide a HLS master URL.
youtube-dl tends to "butcher" it, and the result isn't very ideal. I
guess HLS "renditions" simply don't map well to youtube-dl's output
format and what mpv expects. Playing master HLS directly is also less
than ideal, because of libavformat's stupid probing.
Fix this by not using the delay-opening mechanism if it appears like we
detected such a case. Add a metadata override to set the track titles to
"muxed-N", to indicate that they form a single unit. (Mostly helpful for
testing.)
This is just a more convenient way to start IPC client scripts per mpv
instance.
Does not work on Windows, although it could if the subprocess and IPC
parts are implemented (and I guess .exe/.bat suffixes are required).
Also untested whether it builds on Windows. A lot of other things are
untested too, so don't complain.
Pretty worthless I guess. I only tested one site (and 2 videos), it's
somewhat likely that it will break with other sites. Even if you leave
the option disabled (the default).
Slightly related to #3548. This will allows you to use the bitrate
stream selection mechanism, that was added for HLS, with normal videos.
Until now, filter_sdh was simply a function that was called by sd_ass
directly (if enabled).
I want to add another filter, so it's time to turn this into a somewhat
more general subtitle filtering infrastructure.
I pondered whether to reuse the audio/video filtering stuff - but better
not. Also, since subtitles are horrible and tend to refuse proper
abstraction, it's still messed into sd_ass, instead of working on the
dec_sub.c level. Actually mpv used to have subtitle "filters" and even
made subtitle converters part of it, but it was fairly horrible, so
don't do that again.
In addition, make runtime changes possible. Since this was supposed to
be a quick hack, I just decided to put all subtitle filter options into
a separate option group (=> simpler change notification), to manually
push the change through the playloop (like it was sort of before for OSD
options), and to recreate the sub filter chain completely in every
change. Should be good enough.
One strangeness is that due to prefetching and such, most subtitle
packets (or those some time ahead) are actually done filtering when we
change, so the user still needs to manually seek to actually refresh
everything. And since subtitle data is usually cached in ASS_Track (for
other terrible but user-friendly reasons), we also must clear the
subtitle data, but of course only on seek, since otherwise all subtitles
would just disappear. What a fucking mess, but such is life. We could
trigger a "refresh seek" to make this more automatic, but I don't feel
like it currently.
This is slightly inefficient (lots of allocations and copying), but I
decided that it doesn't matter. Could matter slightly for crazy ASS
subtitles that render with thousands of events.
Not very well tested. Still seems to work, but I didn't have many test
cases.
Uses the infrastructure added in the previous commits. This is
admittedly a bit weird (constructing EDL URLs and such). But on the
other hand, adding this as "first class" mechanism directly to the
sub-add command or so would increase weirdness and unexpected behavior
in other places, or at least that's what I think.
To reduce confusion, this goes through the effort of mapping the webvtt
codec, so it's shown "properly" in the codec list. Without this it would
show "null", but still work. In particular, any non-webvtt codecs should
still work if libavcodec supports it.
Not sure if I should remove the --all-subs hack from the code. But I
guess it does no harm.
A previous commit moved the underrun reporting to report_underruns(),
and called it from get_space(). One reason was that I worried about
printing a log message from a "realtime" callback, so I tried to move it
out of the way. (Though there's little justification other than a bad
feeling. While an older version of the pull code tried to avoid any
mutexes at all in the callback to accommodate "requirements" from APIs
like jackaudio, we gave up on that. Nobody has complained yet.)
Simplify this and move underrun reporting back to the callback. But
instead of printing the message from there, move the message into the
playloop. Change the message slightly, because ao->log is inaccessible,
and without the log prefix (e.g. "[ao/alsa]"), some context is missing.
AOs can report audio underruns, but only ao_alsa and ao_sdl (???)
currently do so. If the AO was marked as not reporting it, the cache
state was used to determine whether playback was interrupted due to slow
input.
This caused problems in some cases, such as video with very low video
frame rate: when a new frame is displayed, a new frame has to be
decoded, and since there it's so much further into the file (long frame
durations), the cache gets into an underrun state for a short moment,
even though both audio and video are playing fine. Enlarging the audio
buffer didn't help.
Fix this by making all AOs report underruns. If the AO driver does not
report underruns, fall back to using the buffer state.
pull.c behavior is slightly changed. Pull AOs are normally intended to
be used by pseudo-realtime audio APIs that fetch an audio buffer from
the API user via callback. I think it makes no sense to consider a
buffer underflow not an underrun in any situation, since we return
silence to the reader. (OK, maybe the reader could check the return
value? But let's not go there as long as there's no implementation.)
Remove the flag from ao_sdl.c, since it just worked via the generic
mechanism. Make the redundant underrun message verbose only.
push.c seems to log a redundant underflow message when resuming (because
somehow ao_play_data() is called when there's still no new data in the
buffer). But since ao_alsa does its own underrun reporting, and I only
use ao_alsa, I don't really care.
Also in all my tests, there seemed to be a rather high delay until the
underflow was logged (with audio only). I have no idea why this happened
and didn't try to debug this, but there's probably something wrong
somewhere.
This commit may cause random regressions.
See: #7440
As requested I guess. It behaves quite similar to the --loop* options.
Not quite happy with the idea that 1) the option is mutated on each
operation (but at least it's consistent with --loop* and doesn't require
more properties), and 2) the ab-loop command will do nothing once all
loop iterations are done. As a concession, the OSD shows something about
"disabled".
Fixes: #7360
Directories inside ~~/scripts/ are now loaded as scripts, so don't use
it also for modules. Now there are no default module paths.
To compensate, we now try to run ~~/.init.js right after defaults.js,
so the user may extend the js init procedure via this script, e.g. for
adding default paths to mp.module_paths .
While mpv normally uses the text a key produces (as opposed to physical
key mappings), this is different with the keypad. This is for the sake
of making it possible to distinguish between these keys and the normal
number keys on the left side of a full size keyboard.
There were complaints that the keypad doesn't interact with console.lua,
so manually map them. This ignores numlock (behaves as if it's always
on), and maps KP_DEC to "." (even though it's mapped to "," on some
keyboards). The /*-+ keys produce ASCII on mpv (at least with X11) as an
inexplicable inconsistency, so there are no mappings for these.
Fixes: #7431
Due to asynchronicity, we generally can't guarantee that a video frame
matches up with other events such as playback time change exactly (since
decoding, presentation, and property update all happen at different
times). This is a complaint in the referenced bug report, where
screenshot filenames in each-frame screenshot did not use the correct
timestamp, and instead was lagging behind by 1 frame.
But in this case, synchronicity was already pretty much forced with wait
calls. The only problem was that the playback time was updated at a
later time, which results in the observed 1 frame lag. Fix this by
moving the place where the screenshot is triggered in this mode.
Normal screenshots may still have the old problem. There is no effort
made to guarantee the timestamps absolutely line up, same as with the
OSD. (If you want a guarantee, you need to use a video filter, such as
libavfilter's drawtext. These will obviously use the proper timestamp,
instead of going through the somewhat asynchronous property etc. system
in the player frontend.)
Fixes: #7433
The script was set up to only call on_update when the changelist
was non-empty. However, since the size operator does not operate
on dicts, it always returned 0 (which is truthy), thus on_update
would always be called when the script-opts property changed.
When switching between having a video visible or not,
stats.lua now picks up the required formatting changes
for the cache stats page to display correctly.
The recently added feature to load scripts from a sub-directory. A
problem was that the script name was still derived from the actual
script source file that was loaded, which was always "main.lua" (or
similar), resulting in "main" as name.
Fix this by using the directory name.
One odd corner case is that you can do "--script=/path/foo////". As by
POSIX semantics, the extra "/" are ignored. However, the newly added
code strips only one separator, so mp_basename() returns "" (as it
should), and the empty name makes mp_new_client() fail in turn. I don't
really care about this, just don't do it. But mp_new_client() failure
was silent (since it normally never happens), so add at least an error
message for that, instead of being entirely silent.
It appears Lua's package paths try to load .lua files from the current
working directory. Not only that, but also shared libraries.
WHAT THE FUCK IS WHOEVER IS RESPONSIBLE FOR THIS FUCKING DOING?
mpv isn't setting this package path; currently it's only extending it.
In any sane world, this wouldn't be a default. Most programs use
essentially random working directories and don't change it.
I cannot comprehend what bullshit about "convenience" or whatever made
them do something this broken and dangerous. Thousands of programs using
Lua out there will try to randomly load random code from random
directories.
In mpv's case, this is so security relevant, because mpv is normally
used from the command line, and you will most likely actually change
into your media directory or whatever with the shell, and play a file
from there. No, you don't want to load a (probably downloaded) shared
library from this directory if a script try to load a system lib with
the same name or so.
I'm not sure why LUA_PATH_DEFAULT in luaconf.h (both upstream and the
Debian version) put "./?.lua" at the end, but in any case, trying to
load a module that doesn't exist nicely lists all package paths in
order, and confirms it tries to load files from the working directory
first (anyone can try this). Even if it didn't, this would be
problematic at best.
Note that scripts are _not_ sandboxed. They're allowed to load system
libraries, which is also why we want to keep the non-idiotic parts of
the package paths.
Attempt to fix this by filtering out relative paths. This is a bit
fragile and not very great for something security related, but probably
the best we can do without having to make assumptions about the target
system file system layout. Also, someone else can fix this for Windows.
Also replace ":" with ";" (for the extra path). On a side note, this
extra path addition is just in this function out of laziness, since
I'd rather not have 2 functions with edit the package path.
mpv in default configuration (i.e. no external scripts) is probably not
affected. All builtin scripts only "require" preloaded modules, which,
in a stroke of genius by the Lua developers, are highest priority in the
load order. Otherwise, enjoy your semi-remote code execution bug.
Completely unrelated this, I'm open for scripting languages and
especially implementations which are all around better than Lua, and are
suited for low footprint embedding.
This simply didn't set the direction flag in most situations, which
meant the timestamps used in the subtitle renderer were nonsense,
leading to invisible subtitles.
This works only for text subtitles that are cached in the ASS_Track
state. Reading new subtitles is broken because the demuxer layer has
trouble returning subtitle packets backwards, and I think for rendering
bitmap subtitles, the pruning direction would have to be adjusted. (Not
sure if reversing the timestamps before the subtitle renderer backend is
even the right thing to do. At least for sd_ass.c, it seems to make
sense, because it caches subtitles with "normal" timestamps.)
The intention is to provide a slightly nicer way to distribute scripts.
For example, you could put multiple source files into the directory, and
then import them from the actual script file (this is still
unimplemented).
At first I wanted to require a config file (because you need to know at
least which scripting backend it should use). This wouldn't have been
too hard (could have reused/abused the mpv config file parsing
mechanism, and I already had working code that was just 2 function
calls). But probably better to do this without new config files, because
it might become a pain in the distant future.
So this just probes for "main.lua", "main.js", etc., until an existing
file is found.
Another important change is that this skips all directory entries whose
name starts with ".". This automatically excludes the "." and ".."
special directories, and is probably useful to exclude random crap that
might be lying around in the directory (such as editor temporary files,
or OSX, in its usual hrmful, annoying, and idiotic modus operandi,
sharting all over any directories opened by "Finder").
Although the changelog mentions the docs, they're added only in a later
commit.
I noticed an oversight when using ytdl-hook -- if the path is a URL, we
try to `stat()` it, which obviously doesn't work. To mitigate that,
don't check or update mtimes for URLs.
this deprecates the old cocoa backend only option and moves it to the
general macos ones. add support for the new option in the cocoa-cb
layer creation and use the new option in the olde cocoa backend.
Fixes#7272
It's ridiculous that --script=something.dumb does not cause an error.
Make it error, and extend this behavior to the scripts/ sub-dir in the
mpv config dir.
I think there was a user complaint that this does not restore the
playlist position.
There's no reason not to save the "state" for unseekable streams; what
we probably don't want is to make restoring trying to issue a seek. So
just don't save the position. (Although we probably could anyway, since
seek requests on unseekable streams are ignored now.)
Fixes: issue number forgotten, if it even exists.
Cache display updates, especially when it's bigger than few minute,
could have been be very infrequent to the point that one is not sure
if it updates at all.
Reduce the 10% change-threshold to 5% and add another threshold of 5s.
There are two improvements here:
1) Correct the right-side padding on the title box. This was messed
up previously because I was passing the title box width when I
should be passing the x coordinate. I've also increased the
spacing to separate the title from the window controls more
clearly.
2) I'ved added a mouse tracking area over the title bar so that the
osc doesn't disappear if you hover over the title box. This didn't
work previously because the input area only covers the actual
window controls. The implementation here is simplified in that
it's only a mouse area and not an input area. This is enough to
keep the osc visible, but it won't stop the mouse pointer
disappearing. Fixing that requires a full input area which, for
now, I will say isn't worth the effort.
It's a bit unintuitive today when you use the un-maximise control
while fullscreened. Depending on the VO in use, this might silently
change the maximise state without any visible effect, or it might
do nothing. It's less surprising if the control exits the fullscreen
state.
Note that the exact behaviour is still VO dependent. If the window
was maximised before being fullscreened, it might exit fullscreen
back to maximised or back to regular window mode.
I thought about trying to explicitly control that behaviour but
it makes the osc code weird and probably wouldn't work all the time.
This code assumed that the function is only called from the playloop
itself (and since property notification is done at the end of it, i.e.
before sleeping, it obviously would not have needed to wake up the
core).
But this function is actually called from some comments (such as
playlist-move), so this assumption was incorrect. Use the same method as
the other function.
Untested.
Fixes: #7339 (probably)
This matches lua's 11b9315b but with the lagacy field names which the
js code used previously.
Currently the property always returns an object (with dummy/last/null
field values if there are no dimensions), but the code is ready for
a future case where it might return null if there are no dimensions - at
which case it will forward the null, breaking backward compatibility for
a better API.
The idea is that if the player is resized, we do not delay redrawing
(which is normally done to limit the redraw rate to something
reasonable).
Not sure if this even does anything. For one, reacting to osd-dimensions
changes is cleaner than just polling the screen size with the next tick
event, and hoping that resizes generate tick events for whatever
logically unrelated reasons.
check_obj_resize() in sub/osd.c calls mp_client_broadcast_event(), which
calls notify_property_events(). This is pretty unexpected, because
check_obj_resize() may be called from the VO thread. While that's sort
of awful, it seems to be OK locking-wise. But it breaks an assumption in
notify_property_events() that the core doesn't need to be woken up,
which could possibly lead to a missed/delayed property update (although
rather unlikely).
Fix this by explicitly waking up the core when it's called from the OSD
code.
This is a gross hack for the shitty design of how VO properties are
handled (which was fine with MPlayer, but became increasingly a shit tub
with mpv's VO thread).
The problem here is that console.lua reads display-hidpi-scale on every
render, but which may take a long time for video timing and vsync
blocking. It will also block the core, making osc.lua unable to react to
window resizing quickly enough.
This should be solved by not using the "classic" blocking VOCTRL
mechanism, and instead side-stepping it with something that doesn't
require any waiting (like for example the "fullscreen" property does).
But this require more thinking and work my "brain" can handle at the
moment. So for now add a shitty hack that will cause a lot of problems,
and which will have to be replaced later. Most importantly, it'll break
theoretic support for multiple screens with different DPI, or runtime
DPI changes. Possibly could affect the Cocoa backend; the X11 isn't
dynamic enough by nature, and other backends do not implement this.
See previous commit.
A nice side-effect is that mp.get_osd_margins() is not a special
Lua-only thing anymore. I didn't test whether this function still works
as expected, though.
This "bundles" all OSD properties. It also makes some previously
Lua-only values available (Lua has mp.get_osd_margins(), unsure if
anything uses it).
The main intention is actually to allow retrieving all fields in an
"atomic" way. (Could introduce a mechanism on the level of the mpv
client API to do this, but doing ti ad-hoc all the time like this commit
is easier.)
The change was not propagated to the OSD/subtitle code, since that still
uses an "old" method. Change it so that the propagation is actually
performed.
(One could argue the OSD/subtitle code should use other ways to update
the options, but that would probably be more effort for now.)
Currently, the activation and deactivation of input handling is done
inside the render() loop, but this does not run when the osc mode is
`never` - which does make sense.
That means that if you are cycling the visibility mode, the input
state will be whatever it was at the time of the mode change. And,
as our modes are ordered `auto` -> `always` -> `never`, the input
state will be enabled when you cycle to `never`.
There are various ways you can imagine fixing this, and in this
change I propose we reset the input state to disabled on a mode
change, and then let render() re-enable input if that's appropriate.
Fixes#7298.
When using --keep-open, and the end of the file is reached, the player's
"pause" property is set to true. Attempting to set it to false reverts
it back to true immediately. That's how it's designed, for better or
worse.
Running "seek -10 ; set pause no" did not work, because the seek is
first queued and pause is unset, but then the decoding functions
determine that EOF is still a thing, and "mpctx->stop_play =
AT_END_OF_FILE;" is set again. handle_keep_open() then sets pause again.
Only then the seek is actually run.
Fix this by not setting stop_play if a seek is queued.
Although a linked list was ideal at first, there are cases where it
sucks, and became increasingly awkward (with the mpv command API
preferring integer indexes to access the list). In future, we probably
want to add more playlist-related functionality, so better change it to
an array now.
An array isn't always ideal either. Since playlist entries are still
separate objects (because in some cases you need a stable "iterator" to
it), but you still need to efficiently get the next/previous playlist
entry, there's a pl_index field, that needs to be maintained. E.g.
adding an entry at the start of the playlist => update the pl_index
field for all other entries. Well, it's not really worth to do something
more complicated to avoid these things.
This commit is probably buggy as shit. It's not like I bothered to test
everything. That's _your_ role.
It's not really great. But I think it's good enough to save someone
who's lost. Most importantly, it should become obvious _what_ the
console expects (input commands), and how to exit it.
Would be nice if we could show some documentation, or give a link to
documentation, but that's out of scope and/or not easy.
I considered implementing the "help" command as builtin command in
command.c. On the other hand, this could not show console.lua specific
help, so I implemented it in console.lua. The ad-hoc command parsing
(that sort-of mirrors mpv input command syntax) for the "help" command
is probably the worst part of this.
It's deprecated. The new solution works almost exactly the same way
(since the still existing internal tick event triggers vsync-jitter
change command), though as far as API usage goes, it's somewhat
questionable. (The comment is meant to discourage anyone trying to copy
the idea for external scripts.)
This affects behavior when using the "del" default key binding.
Sometimes, setting visibility to always did not draw it correctly. This
probably fixes it.
Implemented using one-time idle observer (i.e. setTimeout), to avoid
additional function call(back) every time the event loop enters idle.
The lua mp.flush_key_bindings() is also available, also undocumented.
A minority of users have expressed a dislike of hats, calling them
"cancer [that] don't belong in software" describing the people who add
them as "shitty circlejerks" and "chucklefuck."
While I personally disagree with those opinions, it's probably easier
to let them have it their way. For that reason this adds the option
`greenandgrumpy` to the osc, which allows users to disable the hat.
libass uses integers for PlayResX/Y, so the osd-overlay command also
does. Lua (pre-5.3) does not have an integer type, but the command
interface makes a difference anyway. If you pass a Lua number with a
fractional part to an integer parameter (using mp.command_native()), it
will result in an error and complain about incompatible types.
I think that's fine, but since this behavior extends to
mp.set_osd_ass(), this is a compatibility problem.
Fix this by explicitly coercing the resolution parameters to integer
numbers.
The main reason for this is just to make show the OSC always above
console.lua, instead of a random order.
(And this is also the only reason osc.lua was changed to the new API.
The old API could have been extended, but lets not.)
This tries to avoid the update() call if nothing changed. This brings it
more into line with the old code (the osd-overlay command simply does
not skip the update if nothing changed). I don't know whether this
matters; most likely not. Normally, code should try to avoid redundant
updates on its own, so it's not the job of the command. However, for the
OSC we simply want to reduce the differences.
Lua scripting has an undocumented mp.set_osd_ass() function, which is
used by osc.lua and console.lua. Apparently, 3rd party scripts also use
this. It's probably time to make this a public API.
The Lua implementation just bypassed the libmpv API. To make it usable
by any type of client, turn it into a command, "osd-overlay".
There's already a "overlay-add". Ignore it (although the manpage admits
guiltiness). I don't really want to deal with that old command. Its main
problem is that it uses global IDs, while I'd like to avoid that scripts
mess with each others overlays (whether that is accidentally or
intentionally). Maybe "overlay-add" can eventually be merged into
"osd-overlay", but I'm too lazy to do that now.
Scripting now uses the commands. There is a helper to manage OSD
overlays. The helper is very "thin"; I only want to force script authors
to use the ID allocation, which may help with putting multiple scripts
into a single .lua file without causing conflicts (basically, avoiding
singletons within a script's environment). The old set_osd_ass() is
emulated with the new API.
The JS scripting wrapper also provides a set_osd_ass() function, which
calls internal mpv API. Comment that part (to keep it compiling), but
I'm leaving it to @avih to finish the change.
Lua scripting implements key bindings by defining an input section with
all the bindings in it. Every add_key_binding() call ran a mpv command
to update this section. This caused a lot of spam at debug log levels.
Reduce the spam and more it efficient by batching updates into a single
mpv command when the script becomes inactive. This is pretty simple,
because there's already the concept of idle handlers.
This requires that the script actually goes to sleep, which might not
happen in various extremely bogus corner cases, such as polling the mpv
message queue with active waiting. Just don't do that.
During the 12th month (checked during script initialization), draw a Santa hat
on top of the idle message's logo.
Slightly refactors and optimizes the drawing process as well: reorder original
logo layers and remove redundant holes in them, use a shared line prefix
to clear the style and set start position.

Now that 00af718a made the lua read_options behavior much more similar
to the js behavior, the main difference was that lua does not re-read
the config file at on_update (but it does re-apply its stored content)
while js did re-read it.
Now the js on_update also does not re-read the config file and instead
applies its stored original content.
This is slightly hacky by adding an undocumented optional 4th argument
to read_options which allows overriding the config file content.
Make sure it gets properly reinitialized when needed. This is especially
useful now that the OSC reacts to runtime option changes, which can
change the layout too.
This may call set_property_number() on the margin properties more often
now, but since redundant option changes are ignored now, this shouldn't
have any too bad effects.
Fuck it, just let's just reinit everything.
On a side note, the changelist parameter provided by read_options()
(here "list") is now unused. But it's not hard to provide and might be
useful for other stuff. So don't remove it from the generic
read_options() code.
As described in the manpage changes. This makes more sense than the
previous approach, where options could "unexpectedly" stick. Although
this is still a somewhat arbitrary policy (ask many people and you'd get
a number of different expectations on what should happen), I think that
it reflects what mpv's builtin stuff does.
All the copying is annoying, but let's just hope nobody is stupid enough
to change these properties per video frame or something equally
ridiculous.
This is a bit different than the lua code: on script-opts change it
simply re-applies the conf-file and script-opts to the options object,
and if this results in any changed value at options then on_update is
called with the changelist as argument.
This allows a value to revert back to the conf-file value if the
matching script-opts key had a different value and then got deleted.
It also guarantees to call back whenever the options object is
modified, which the lua code doesn't do (e.g. if the caller changed
a value and the observer changed it back - it won't detect a change).
With special attention to changing osc-visibility. Untested, although
osc-visibility works (it's pretty much equivalent to the key binding, so
there is not much interesting going on).
Somewhat inspired by code posted by github user CogentRedTester.
Fixes: #4513
The way how this modifies and backups/restores user option values is a
bit of a problem for runtime option changing.
Clean this up a little. Now cycling the visibility updates the user
option value, but always to "valid" values (unlike hidetimeout used to
be used). If the user option value is changed externally (enabled by a
later commit), it'll be cleanly overwritten.
I decided to factor this into the user's scale option (instead of
somehow using it as default if the user has not specified it), because
it makes the option handling simpler, and won't break things like
per-screen DPI if the user only wants to scale the console font by a
factor.
