MPlayer traditionally had completely separate sh_ structs for
audio/video/subs, without a good way to share fields. This meant that
fields shared across all these headers had to be duplicated. This commit
deduplicates essentially the last remaining duplicated fields.
|
| |
|
|
| |
This makes the code slightly more generic.

Instead of bstr. Most callers of this function do not need bstr. The
bstr version of this function is now mp_path_join_bstr().

Because gcc (and clang) is a goddamn PITA and unnecessarily warns if
the universal initializer for structs is used (like mp_image x = {})
and the first member of the struct is also a struct, move the w/h
fields to the top.

They are redundant. They were used by draw_bmp.c only, and only in a
special code path that 1. used fixed image formats, and 2. had image
sized perfectly aligned to chroma boundaries (so computing the chroma
width/height is trivial).

Realistically probably no problem at all since they're in ms and usually
start from 0, but whatever.

Prefer the builtin one again. libavcodec still uses the ASS packet
format that uses inline timestamps, so the packet timestamps are
ignored. This again leads to additional rounding of timestamps, because
the ASS storage format only has 10ms resolution (instead of 1ms
resolution like libass). This again can lead to unintentional overlaps
when converting subtitles. The internal MicroDVD converter avoids this,
because it always uses packet timestamps.

Remove the colorspace-related top-level options, add them to vf_format.
They are rather obscure and not needed often, so it's better to get them
out of the way. In particular, this gets rid of the semi-complicated
logic in command.c (most of which was needed for OSD display and the
direct feedback from the VO). It removes the duplicated color-related
name mappings.
This removes the ability to write the colormatrix and related
properties. Since filters can be changed at runtime, there's no loss of
functionality, except that you can't cycle automatically through the
color constants anymore (but who needs to do this).
This also changes the type of the mp_csp_names and related variables, so
they can directly be used with OPT_CHOICE. This probably ended up a bit
awkward, for the sake of not adding a new option type which would have
used the previous format.

This has a number of user-visible changes:
1. A new flag blend-subtitles (default on for opengl-hq) to control this
behavior.
2. The OSD itself will not be color managed or affected by
gamma controls. To get subtitle CMS/gamma, blend-subtitles must be
used.
3. When enabled, this will make subtitles be cleanly interpolated by
:interpolation, and also dithered etc. (just like the normal output).

There's literally no reason why these functions have to be inline (they
might be performance critical, but then the function call overhead isn't
going to matter at all).
Uninline them and move them to mp_image.c. Drop the header file and fix
all uses of it.

There was a somewhat obscure optimization in the OSD and subtitle
rendering path: if only the position of the sub-images changed, and not
the actual image data, uploading of the image data could be skipped. In
theory, this could speed up things like scrolling subtitles.
But it turns out that even in the rare cases subtitles have such scrolls
or axis-aligned movement, modern libass rarely signals this kind of
change. Possibly this is because of sub-pixel handling and such, which
break this.
As such, it's a worthless optimization and just introduces additional
complexity and subtle bugs (especially in cases libass does the
opposite: incorrectly signaling a position change only, which happened
before). Remove this optimization, and rename bitmap_pos_id to
change_id.

Update options like --sub-text-margin-y at runtime. These are somewhat
of a problem, because ass_set_selective_style_override() (intentionally)
does not override them. This should be fixed in libass (by providing
additional override modes), but for now this will do.
Also change the signature of mp_ass_configure(), so we can get access to
the track.
Additionally, drop the redundant setting of the style Alignment (it's
overwritten by mp_ass_set_style()).
See #1622 (again).

sd_ass.c is the only user, and the function is starting to become
extremely "special". No other changes.

Overwrite the alignment applied by the OSD style. Additionally, remove
the initialization of the Alignment field in create_ass_track(); the
value is always overwritten by mp_ass_set_style() later.
Fixes #1626.

There was some logic to set certain things on init only. Not sure why
this was done (saving some cheap calculations?) - but since the next
call would override these style settings by applying the usual subtitle
style, I don't think this was intended.
|
| |
|
|
|
|
|
|
|
|
| |
Basically abuse the style override mechanism meant for ASS
(mp_ass_set_style()) to update text subtitle styling at runtime too.
This even has the advantage that the style will be overridden, even if
the text subtitle converted (like sd_lavc_conv.c) dares to add a fixed
style in the styles section.
Probably helps with #1622.

Now --ass-use-margins doesn't apply to normal subtitles anymore. This is
probably the inverse from the mpv behavior users expected so far, and
thus a breaking change, so rename the option, that the user at least has
a chance to lookup the option and decide whether the new behavior is
wanted or not.
The basic idea here is:
- plain text subtitles should have a certain useful defalt behavior,
like actually using margins
- ASS subtitles should never be broken by default
- ASS subtitles should look and behave like plaintext subtitles if
the --ass-style-override=force option is used
This also subtly changes --sub-scale-with-window and adds the --ass-
scale-with-window option. Since this one isn't so important, don't
bother with compatibility.

You can set in which "corner" the OSD and subtitles are shown. I'd
prefer it a bit more general (so you could set the alignment using
a factor), but the libass API does not provide this.

Until now, they used exactly the same defaults for the styling options.
The defaults were shared, so it was impossible to have different
defaults. Change this. This requires duplicating the full default
struct, even for settings that are the same. The list of options is
still shared, though.
|

This behavior is implied by VSFilter.

Apparently some people want this. Not enabled by default.

Commit 87c13de6 added a fallback to video resolution if the subtitle
resolution is unknown. Apparently this fixed some broken files with
vobsubs.
This broke some DVB subtitles. Apparently .ts captures with 1920x1080
video resolution and 720x576 subtitles do exist. The sample at hand had
some streams with 720x576 resolution and no sub resolution set, and some
streams with 1920x1080 resolution and sub resolution set (both against
the same 1920x1080 video). My conclusion is that 720x576 is the only
reasonable fallback for DVB (but I can't be sure).
The fallback is removed for PGS too. I don't know about the PGS case; it
seems the sub resolution must always be set, so it shouldn't matter.
Fixes #1425.

Not being able to use the 3x3 part of the matrix was annoying, so split
it into a float[3][3] matrix and a separate float[3] constant vector.

Although the line count increases, this is better for making sure
everything is handled consistently for all users of the mp_csp_params
stuff.
This also makes sure mp_csp_params is always initialized with
MP_CSP_PARAMS_DEFAULTS (for consistency).

--sub-scale-by-window=no attempts to keep subs always at the same pixel
size.
The implementation is a bit all over the place, because it compensates
already done scaling by an inverse scale factor, but it will probably do
its job.
Fixes #1424. (The semantics and name of --sub-scale-with-window are
kept, and this adds a new option - the name is confusingly similar, but
it's actually analogue to --osd-scale-by-window.)

Most image subtitle formats implicitly terminate the current subtitle
event with the next event (e.g. a new packet read from the demuxer will
instruct the subtitle render to stop display). If the subtitle event is
just trailing, it will be displayed forever. So there's no proper way
of doing this and we just apply an heuristic to avoid annoyances.

The libavcodec PGS decoder sets end_display_time to UINT32_MAX, in an
attempt to signal unknown end time (the API does not allow to signal
this properly, and this was a backwards compatible hack).
While we have no issues with the large value, our code wants to
distinguish between known and unknown end time explicitly.

Makeshift-solution for working around certain fontconfig issues.
With --use-text-osd=no, libass and fontconfig won't be initialized, and
fontconfig won't block everything with scanning for fonts.

Silences a Coverity warning.
Also, drop the assert(); although it should be pretty much guaranteed
that things happen this way, it's still a bit fuzzy.

Getting subtitle scaling and positioning right even if there are video
filters, which completely change the image (like cropping), doesn't seem
to have a single, correct solution. To some degree, the results are
arbitrary, so we may as well do what is most useful to the user.
In this case, if the PGS resolution aspect ratio and the video output
aspect ratio mismatch, letter-box it, instead of stretching the subs
over the video frame. (This will require additional fixes, should it
turn out that there are PGS subtitles which are stretched by design.)
Fixes #1205.

Now requires newest libass git. Since this feature wasn't part of a
libass release yet, I'm not bothering making the mpv code compatible
with as how it was previously implemented (it will just be disabled
with any older libass).
CC: @mpv-player/stable (because mpv-build uses libass git, and this
breaks the feature)

The one in msg.c was mistakenly removed with commit e99a37f6.
I didn't actually test the change in ao_sndio.c (but obviously "ap"
shouldn't be static).

Simple fix for issue #1137.
Since all sub-bitmaps are packed on a larger texture, there's still a
"fall off" on the border due to the linear scaling. This could be
fixed by constraining each sub-bitmap to its own texture, or by
clamping on the shader level, but I don't care for now.

We don't allow this by default, because it would be silly if random
external data (like filenames or file tags) could accidentally trigger
them.
Add a property that magically disables this ASS tag escaping.
Note that malicious input could still disable ASS tag escaping by
itself. This would be annoying but harmless.
