Apparently a relatively widespread convention, and almost as strict as
the old "exact" semantics. (So it's not going to auto load radically
unrelated files.)
Fixes#4626. Previously removed because the original smi entry was added
by someone who did not agree to LGPL relicensing. I'm not sure if the
original change was copyrightable, but this commit for sure does not
fall under that author's copyright.
While we could easily ifdef-out this file for a LGPL core, it's still
annoying, and also the only GPL file remaining in player/ that is not
based on mplayer.c.
This file originates from subreader.c. It's not clear whether the
original author of it gave us permission to relicense to LGPL (he
probably did, but without further clarification it's sort of ambiguous),
but the subtitle file search code was written by other authors anyway
(see 7eef93819f).
One contribution (574eb892ea) is a bit of a corner case, as
test_ext_list() now does a bstrcasecmp(). But I don't think the
copyright remains here. (I asked the author anyway, just in case. But
I didn't wait for the answer.)
In some other cases, contributors who could not be reached added some
subtitle extensions. I don't think those are copyrightable on their own,
but I dropped them anyway just to be sure.
It's been missing since mplayer2 times, not sure why. It originates from
subreader.c. No analysis on whether it can be relicensed to LGPL was
done yet.
The 'sub' and 'audio' configuration subdirectories are supposed to
be fallbacks for sub-paths and audio-file-paths respectively, but
they weren't being scanned even if they existed.
If used with fuzzy matching, the player tends to pick up random text
files, sometimes with interesting results.
The most interesting interaction is when the user uses
--log-file=something.txt, and mpv tries to open its own log file. It
essentially "freezes" during probing, because every time it reads from
it, it will write some more data, which in turn will cause more data to
be read - until the 2MB max. probing size is slowly reached. This is not
even an obscure corner case, but happened to multiple users.
The .txt extension has been considered a subtitle extension ever since
the code was added to MPlayer's subreader.c, but I'm not seeing many
actual subtitle files with this extension, so just get rid of it.
several unicode characters can be encoded in two different ways, either
in a precomposed (NFC) or decomposed (NFD) representation. everywhere
besides on macOS, specifically HFS+, precomposed strings are being used.
furthermore on macOS we can get either precomposed or decomposed
strings, for example when not HFS+ formatted volumes are used. that can
be the case for network mounted devices (SMB, NFS) or optical/removable
devices (UDF). this can lead to an inequality of actual equal strings,
which can happen when comparing strings from different sources, like the
command line or filesystem. this makes it mainly a problem on macOS
systems.
one case that can potential break is the sub-auto option. to prevent
that we convert the search string as well as the string we search in to
the same normalised representation, specifically we use the decomposed
form which is used anywhere else.
this could potentially be a problem on other platforms too, though the
potential of occurring is very minor. for those platforms we don't
convert anything and just fallback to the input.
Fixes#4016
Requested. Supposedly "scenarist closed captions".
(The list of getting quite full. But it's probably still better than
trying to probe the files by contents, because the external subtitle
loader code will initially look at _all_ files in the same directory as
the main file.)
OK, this made the --sub-paths and --audio-file-paths synonyms, which is
not what we wanted. Actually restrict the type of file loaded as well.
Really fixes#2632.
Requested. It works like --sub-paths. This will also load audio files
from a "audio" sub directory in the config file (because the same code
as for subtitles is used, and it also had such a feature).
Fixes#2632.
This was in sub/, because the code used to be specific to subtitles. It
was extended to automatically load external audio files too, and moving
the file and renaming it was long overdue.
