since i was going to fix the include order of stdatomic, might as well
sort the surrouding includes in accordance with the project's coding
style.
some headers can sometime require specific include order. standard
library headers usually don't. but mpv might "hack into" the standard
headers (e.g pthreads) so that complicates things a bit more.
hopefully nothing breaks. if it does, the style guide is to blame.
replace it with <stdatomic.h> and replace the mp_atomic_* typedefs with
explicit _Atomic qualified types.
also add missing config.h includes on some files.
Abstracts a common pattern,
in which the av dictionary is cleared
immediately after copying to mp tags,
so that additional tags later in the stream
get appended to empty tags,
instead of being appended to existing tags
that were already copied.
This was wrongly assuming that playlist_path is always set for the
current playlist entry, but it's only set when a file was added by
expanding a playlist.
The crash in playlist_get_first_in_next_playlist can be reproduced with
mpv foo.mkv foo.zip, playlist-next, playlist-prev,
playlist-next-playlist. You need to run playlist-next, playlist-prev
first because foo.zip's playlist_path is NULL until you do that, which
makes playlist_get_first_in_next_playlist return immediately.
The crash in cmd_playlist_next_prev_playlist can be replicated with mpv
--loop-playlist foo.zip foo.mkv, running playlist-next until foo.mkv,
and playlist-play-next. Again, you need to open foo.zip first or its
playlist_path is NULL which skips running strcmp(entry->playlist_path,
mpctx->playlist->current->playlist_path).
Fixes https://github.com/mpv-player/mpv/issues/12495#issuecomment-1760968608
playlist-prev-playlist goes to the beginning of the previous playlist
because this seems more useful and symmetrical to
playlist-next-playlist. It does not go to the beginning when the current
playlist-path starts with the previous playlist-path, e.g. with mpv
--loop-playlist foo/, which expands to foo/{1..9}.zip, the current
playlist path foo/1.zip beings with the playlist-path foo/ of {2..9}.zip
and thus playlist-prev-playlist goes to 9.zip rather than to 2.zip.
Closes#12495.
2c6a3cb1f27e02b2e66390a2465ab648905a64d0 originally added this struct
member and then 1be863afdbe9017aa227234e8525b209fb818224 later added
some more logic to loadfile that uses this. There's been more changes
since then of course, but bits using playback_short and playback_start
have mostly stayed the same. It's a bit strange it's worked this way for
so long since it makes an assumption on how long files should be and
leads to weird, broken behavior on playlists with shorter videos. The
main reason for playlist_short, as far as I can tell, is to deal with
some fringe cases with short videos and trying to go back in the
playlist. More specifically, if you use --loop=inf on a very short video
(say less than 1 second) and try to go back in the playlist, you won't
be able to without any of this special logic that deals with it. But the
current approach has several side effects like going back multiple items
in the playlist instead of just one if the video is less than one
second. This is just bad so delete everything related to playlist_short
and playlist_start.
Instead, let's handle this by keeping track of playlist-prev attempts.
Going forward in the playlist doesn't require any special handling since
a bad/broken file will just advance to the next one. So it's only going
backwards that requires some special consideration. If we're going
backwards and the user isn't using force, then mark the playlist entry
with a special flag. If the file loads successfully in
play_current_file, we can just clear the flag and not worry about it.
However if there's a failure, then we set a bool telling
play_current_file that it should go back one more item in the playlist
if possible and try again. This way, we avoid the previously mentioned
--loop=inf edgecase and the user can still attempt to retry previously
failed items in the playlist (like a url or such).
Fixes#6576, fixes#12548.
The timestamps when making a log file is actually dependent on
MP_START_TIME. This is a 10 microsecond offset that was added to the
timer as an offset. With the nanosecond change, this unit needs to be
converted as well so the offset is the same as before. After doing that,
we need to change the various mp_time_us calls in msg to mp_time_ns and
do the right conversion. This fixes the logs timestamps (i.e. so they
aren't negative anymore).
A bit different from the OPT_REPLACED/OPT_REMOVED ones in that the
options still possibly do something but they have a deprecation
message. Most of these are old and have no real usage. The only
potentially controversial ones are the removal of --oaffset and
--ovoffset which were deprecated years ago and seemingly have no real
replacement. There's a cryptic message about --audio-delay but who
knows. The less encoding mode code we have, the better so just chuck
it.
We've got an ungodly amount of OPT_REPLACED and OPT_REMOVED sitting
around in the code. This is harmless, but the vast majority of these are
ancient. 26f4f18c0629998a9b91e94722d166866d8b80a3 is the last commit
that touched the majority of these and of course that only changed how
options were declared so all of this stuff was deprecated even before
that. No use in keeping these, so just delete them all. As an aside,
there was actually a cocoa_opts but it had only a single option which
was replaced by something else and empty otherwise. So that entire thing
was just simply removed. OPT_REPLACED/OPT_REMOVED declarations that were
added in 0.35 or later were kept as is.
It turns out that the code to track redirects (playlists and
directories) never worked correctly, only the last redirect is
remembered and num_redirects is never greater than 1.
You can see this by doing quit-watch-later with the old watch later
system, before dbf244fd2f, on a m3u playlist of files and a m3u playlist
of directories. Only in the first case a redirect entry for the m3u file
is created, because in the second case the m3u redirect is replaced by
the directory one.
If you did mpv --directory-mode=lazy /foo it did create redirect entries
for all subdirectories e.g. /foo/bar, /foo/bar/baz, /foo/bar/baz/qux,
this made it seem like it worked correctly, but actually
/foo/bar/bar/qux was the only redirect entry and thus it was considered
as the first redirect, and mpv created redirect entries for each segment
of the first redirect only.
In the previous commit dbf244fd2f, rather than figuring out how to fix
the code to track redirects, and since creating redirect entries for
multiple redirects is overkill, I just used the new playlist-path
property which does the same thing but only for the last redirect.
By replacing the only other use of the old redirect code with
playlist-path, we can remove it.
A bit of a long standing pain with scripting is that when opening a file
that gets interpreted as a playlist (like an m3u), the original path of
the file gets thrown away later. Workarounds basically consist of
getting the filename before mpv expands the path, but that's not really
reliable. Instead of throwing it away, save the original playlist path
by copying to the playlist entries when applicable (demuxer playlist and
the playlist option). Then expose these as properties: playlist-path for
the currently playing entry and playlist/N/playlist-path for each
specific entry. Closes#8508, #7605.
After second thought version.py does not do anything useful. Meson has
built-in function vcs_tag that mostly replicate what version.py did. For
the build time we can just use __DATE__ and __TIME__. Of course this
changes time string format a little, but in my opinion it looks nicer in
fact.
Also it will use local time, instead UTC. But I would argue that date
string is only informative for users to check how old the specific mpv
build is. It doesn't have to be precise, it weren't for years anyway
before recent change.
This only existed as essentially a workaround for meson's behavior and
to maintain compatibility with the waf build. Since waf put everything
in a generated subdirectory, we had to put make a subdirectory called
"generated" in the source for meson so stuff could go to the right
place. Well now we don't need to do that anymore. Move the meson.build
files around so they go in the appropriate place in the subdirectory of
the source tree and change the paths of the headers accordingly. A
couple of important things to note.
1. mpv.com now gets made in build/player/mpv.com (necessary because of
a meson limitation)
2. The macos icon generation path is shortened to
TOOLS/osxbundle/icon.icns.inc.
mpv has a convention of printing everything to stdout. The reasons for
this are pretty unclear and in certain situations rather unintuitive. It
leads to some bad behavior in fringe cases with encoding mode and isn't
the norm for programs so just adjust it so warnings and up are printed
to stderr. Fixes#8608.
This adds cache as a possible path for mpv to internally pick
(~/.cache/mpv for non-darwin unix-like systems, the usual config
directory for everyone else). For gpu shader cache and icc cache,
controlling whether or not to write such files is done with the new
--gpu-shader-cache and --icc-cache options respectively. Additionally,
--cache-on-disk no longer requires explicitly setting the --cache-dir
option. The old options, --cache-dir, --gpu-shader-cache-dir, and
--icc-cache-dir simply set an override for the directory to save cache
files. If unset, then the cache is saved in XDG_CACHE_HOME.
A pain point for some users is the fact that watch_later is stored in
the ~/.config directory when it's really not configuration data. Roughly
2 years ago, XDG_STATE_DIR was added to the XDG Base Directory
Specification[0] and its description, user-specific state data, actually
perfectly matches what watch_later data is for. Let's go ahead and use
this directory as the default for watch_later. This change only affects
non-darwin unix-like systems (i.e. Linux, BSDs, etc.). The directory
doesn't move for anyone else.
Internally, quite a few things change with regards to the path
selection. If the platform in question does not have a statedir concept,
then the path selection will simply return "home" instead (old
behavior). Fixes#9147.

They should not be modifying the argument, so clearly marking it
as const makes sure we don't do it in the future as well as allows
for read-only optimizations.
c784820454 introduced a bool option type
as a replacement for the flag type, but didn't actually transition and
remove the flag type because it would have been too much mundane work.
Previously, if log-file was set not via a CLI option (e.g. set via
mpv.conf or other config file, or set from a script init phase),
then meaningful early log messages were thrown away because the log
file name was unknown initially.
Such early log messages include the command line arguments, any
options set from mpv.conf, and possibly more.
Now we store up to 5000 early messages before the log file name is
known, and flush them once/if it becomes known, or destroy this
buffer once mpv init is complete.
The implementation is similar and adjacent, but not identical, to an
existing early log system for mpv clients which request a log buffer.
In debug mode the macro causes an assertion failure.
In release mode it works differently and tells the compiler that it can
assume the codepath will never execute. For this reason I was conversative
in replacing it, e.g. in mpv-internal code that exhausts all valid values
of an enum or when a condition is clear from directly preceding code.
So far there was no way to sync video to display and have audio sync to
video without changes in pitch.
With this option the audio does not get resampled (pitch change) and
instead the corrected audio speed is applied to audio filters.
This has been a long standing annoyance - ffmpeg is removing
sizeof(AVPacket) from the API which means you cannot stack-allocate
AVPacket anymore. However, that is something we take advantage of
because we use short-lived AVPackets to bridge from native mpv packets
in our main decoding paths.
We don't think that switching these to `av_packet_alloc` is desirable,
given the cost of heap allocation, so this change takes a different
approach - allocating a single packet in the relevant context and
reusing it over and over.
That's fairly straight-forward, with the main caveat being that
re-initialising the packet is unintuitive. There is no function that
does exactly what we need (what `av_init_packet` did). The closest is
`av_packet_unref`, which additionally frees buffers and side-data.
However, we don't copy those things - we just assign them in from our
own packet, so we have to explicitly clear the pointers before calling
`av_packet_unref`. But at least we can make a wrapper function for
that.
The weirdest part of the change is the handling of the vtt subtitle
conversion. This requires two packets, so I had to pre-allocate two in
the context struct. That sounds excessive, but if allocating the
primary packet is too expensive, then allocating the secondary one for
vtt subtitles must also be too expensive.
This change is not conditional as heap allocated AVPackets were
available for years and years before the deprecation.
Add xoshiro as a PRNG implementation instead of relying
on srand() and rand() from the C standard library. This,
in particular, lets us avoid platform-defined behavior with
respect to threading.
The video sync logic for mpv lies completely within its core at
essentially the highest layer of abstraction. The problem with this is
that it is impossible for VOs to know what video sync mode mpv is
currently using since it has no access to the opts. Because different
video sync modes completely changes how mpv's render loop operates, it's
reasonable that a VO may want to change how it renders based on the
current mode (see the next commit for an example).
Let's just move the video sync option to mp_vo_opts. MPContext, of
course, can still access the value of the option so it only requires
minor changes in player/video.c. Additionally, move the VS_IS_DISP
define from to player/core.h to common/common.h. All VOs already have
access to common/common.h, and there's no need for them to gain access
to everything that's in player/core.h.
FFmpeg recently split version.h into version.h and
version_major.h, and no longer automatically includes
version.h in avcodec.h (and the other libraries). This
should allow mpv to build against ffmpeg git master. See
FFmpeg/ffmpeg@f2da2e1458
These headers are not new, so their inclusion should not affect
backwards compatibility.
Though, only when the output format is matroska, to avoid muxing errors.
This is quite useful when the input has ASS subtitles, as they tend to
rely on embedded fonts.
I've looked and studied the flow in the recorder, and to my
understanding, the packet queue is moot after the initial sync, maybe
even then - but that's beyond me right now.
With the previous choice to mux trailing packets whatever the case, this
doesn't result in any new ill effects (and some missing packets at the
end is no big deal).
Notably, since we don't have to hold onto the packets after we get
muxing, we'll never run into any issues with veeery long GOPs filling up
our queue (resulting in dropped packets and much user chagrin).
For muxing, FFmpeg expects the FLAC extradata to be just the bare STREAMINFO,
and passing the full FLAC extradata (fLaC header and block size, with any
additional channel layout metadata) will result in malformed output, as
ffmpeg will simply prefix another fLaC header in front.
This can be considered to be a bug.
FFmpeg's own demuxers only store the STREAMINFO, hence the naivety, while
our common source of FLAC streams, the matroska demuxer, holds onto the
full extradata. It has been deemed preferable to adjust the extradata upon
muxing, instead of in the demuxer (ffmpeg's FLAC decoder knows to read
the full fLaC extradata).
This fixes muxing FLAC streams, meaning recorder.c or dump-cache.
In commit f7678575a5, wm4 chooses to mux
all remaining packets when mp_recorder_mark_discontinuity() is called and
adds a call to mux_packets(). However, it is called only after flush_packets(),
which clears the packets before they can be muxed out. This has no ill
effects per se - recordings end on keyframes, as before - but judging from
his commit message, the intention explicitly was to output the inter
frames, since long GOPs can mean several seconds of missing content from
the output. So, clear the stream packet queues only after the final mux.
Also, flushing can mean both discarding and committing. What a country!
Avoiding blindly copying the codec_tag between different formats allows
us to mux packets from, say, mpegts streams to matroska, making the
recorder (dump-cache) much more usable as unsupported codec_tags can
make the muxer reject the streams.
