Without this change, fields that can be sometimes empty and
sometimes not, such as the Effect field, are counted in an
inconsistent way. Since the number of fields is used to find
where the text starts, it leads to internal field arriving
on the video.

In order to improve performance, vo_xv didn't create a backup of the
video frame before drawing OSD and subtitles during normal playback. It
required the frontend to do frame stepping if it wanted to redraw the
OSD, but no backup of the video frame was available. (Consider the
following use case: enable the OSD permanently with --osd-level=3, then
pause during playback and do something that shows an OSD message. The
player will advance the video by one frame at the time the new OSD
message is first drawn.)
This also meant that taking a screenshot during playback with vo_xv
would include OSD and subtitles in the resulting image.
Fix this by always creating a backup before drawing OSD or subtitles.
In order to avoid having to create a full copy of the whole image frame,
introduce a complex scheme that tries to backup only the changed
regions.
It's unclear whether the additional complexity in draw_bmp.c for
backing up only the changed areas of the frame is worth it. Possibly
a simpler implementation would suffice, such as tracking only Y ranges
of changed image data, or even just copying the full frame.
vo_xv's get_screenshot() now always creates a copy in order not to
modify the currently displayed frame.
Make more aspects of the OSD font customizable. This also affects the
font used for unstyled subtitles (such as SRT), or when using the
--no-ass option. This adds back some customizability that was lost with
commit 74e7a1 (osd: use libass for OSD rendering).
Removed options:
--ass-border-color
--ass-color
--font
--subfont
--subfont-text-scale
Added options:
--osd-color
--osd-border
--osd-back-color
--osd-shadow-color
--osd-font
--osd-font-size
--osd-border-size
--osd-margin-x
--osd-margin-y
--osd-shadow-offset
--osd-spacing
--sub-scale
The font size is now specified in pixels as it would be rendered on a
window with a height of 720 pixels. OSD and subtitles are always scaled
with the window height, so specifying or expecting an absolute font
size doesn't make sense.
Such scaled pixel units are used to specify font border etc. as well.
(Note: the font size is directly passed to libass. How the fonts are
actually rasterized is outside of our control, but in theory ASS font
sizes map to "script" pixels and then are scaled to screen size.)
The default settings should be about the same, with slight difference
due to rounding to the new scales.
The OSD and subtitle fonts are not separately configurable. It has
limited use and would double the number of newly added options, which
would be more confusing than helpful. It could be easily added later,
should the need arise.
Other small details that change:
- ASS_Style.Encoding is not set to -1 for subs anymore
(assuming subs use VSFilter direction in -no-ass mode too)
- use a different WrapStyle for OSD
- ASS forced styles are not applied to OSD
Most of these are reimar fixing issues found by Coverity static
analyzer, and possibly some more cleanup commits independent from
this.
Since these commits are rather noisy, squash them all together.
Try to make code a bit clearer.

Mostly pedantic bikeshedding issues.
Move some code around, so that the sub_bitmap_to_mp_images() function
can be split into two parts. This is better than having a big function
with many input and outputs, of which only half are used in each code
path.
Also, try to make code simpler by using a mp_rect type.
This controlled the generation of the palette for DVD subs if no palette
was found. The option name and description is confusing, and it was
probably barely useful. Remove the option, and hardcode the behavior to
the option's default value.
The code for this option attempted to emulate the old as-documented
behavior. It wasn't very good at it, and now that the old OSD code has
been removed, it's entirely pointless.
This removes the factor 1.7 with which --subfont-text-scale was
multiplied.
Most of these cased working when the OSD was switched to libass, or
didn't do anything even before that.
Also don't recursively include subreader.h in sub.h.
Normally, we can redraw the OSD any time. But some drivers don't support
OSD redrawing (vo_null etc.), or only "sometimes" (vo_xv). For that,
some additional logic is needed. Simplify that logic. This might also
fix subtle bugs with the OSD not updating or endless frame stepping in
unforseen corner cases.
Do this by adding a new flag, which tells whether the OSD should be
redrawn.
Remove some minor code duplication.
Remove VFCTRL_DRAW_OSD, VFCAP_EOSD_FILTER, VFCAP_EOSD_RGBA, VFCAP_EOSD,
VOCTRL_DRAW_EOSD, VOCTRL_GET_EOSD_RES, VOCTRL_QUERY_EOSD_FORMAT.
Remove draw_osd_with_eosd(), which rendered the OSD by calling
VOCTRL_DRAW_EOSD. Change VOs to call osd_draw() directly, which takes
a callback as argument. (This basically works like the old OSD API,
except multiple OSD bitmap formats are supported and caching is
possible.)
Remove all mentions of "eosd". It's simply "osd" now.
Make OSD size per-OSD-object, as they can be different when using
vf_sub. Include display_par/video_par in resolution change detection.
Fix the issue with margin borders in vo_corevideo.
Do this by replacing all the old vf_ass drawing code by draw_bmp.c.
Change sub.c to always use osd_draw() for the other OSD drawing
routines, and simplify the code a bit.
spudec.c subtitles (i.e. DVD subs) are now considered subtitles, and
are rendered by vf_ass, if that filter is inserted.
This fixes that vo_xv didn't display text subtitles correctly when
using anamorphic video. It didn't pass the aspect information to the
subtitle renderer. Also, try to render OSD correctly with respect to
aspect ratio settings: on vo_xv, the OSD is rendered into the video,
and needs to be "stretched" too when playing anamorphic video. When
the -monitorpixelaspect option is used, even with VOs such as vo_opengl
the OSD has to be rendered with that aspect ratio.
As preparation for future commits, replace the weird vsfilter_scale
value with a somewhat more sensible video_par member.
Also, struct mp_eosd_res is a better place for the aspect ratio
parameters, as OSD needs this too.
Use osd_draw_on_image() directly in vo_lavc, which fixes aspect ratio
issues as well.
Just to get rid of that conversion copy&pasted from the internet.
R and G are swapped for unknown reasons. Testing various subtitles
seem to yield the same results as VLC. The sub-bitmap renderers output
the correct colors. The colorspace conversion is used without problems
for vo_gl, vo_gl3 and vo_vdpau. The problem is most likely that
apparently, the DVD palette read from the subtitle track extradata is
converted to YUV using vobsub_palette_to_yuv(), and swapped in the
process. Or in other words, the YUV colors spu->global_palette are
encoded with R and G swapped.
Add some utility definition to csputils.c/h to make converting single
color values easier.
To ease changing all the VOs to the new OSD rendering, fallbacks,
conversions, support code etc. was left all over the code. Now that
all VOs have been changed, all that code is inactive. Remove it.
Strip down spudec.c. We don't need the old grayscale and scaling stuff
anymore. (Not removing spudec itself yet - I'm not confident that the
libavcodec DVD sub decoder is sufficient, and it would also require
some hacks to get DVD palette and resolution information from libdvdread
to libavcodec.)
The option --spuaa, --spualign, --spugauss were used with the old sub
scaling code, and don't do anything anymore.
draw_bmp.c uses libswscale, which has strict alignment requirements on
input images. Since imp_convert.c is currently the only producer of RGBA
sub-bitmaps, the overall code becomes easier if the alignment is done on
image allocation, rather than forcing draw_bmp.c to create an aligned
copy.
talloc doesn't align to 16 bytes, as required by libswscale. Apparently,
system malloc (glibc/Linux/32 bit) aligns to 8 bytes only, so talloc's
own code to align to 16 bytes is ineffective. Work around by using
mp_image to allocate the image.
The osd_draw_on_image() function renders the full OSD into the provided
image.
It uses the mp_draw_sub_bitmaps() function added in the previous commit
to do the actual work.
libswscale tends to overwrite the area between (w,y)-(0,y+1). It tries
to process multiple pixels at once, and if the memory past the last x
pixel is inside a SIMD operation, but still below the image stride, it
overwrites that data with black.
This happens with vo_x11 and 32 bit RGBA formats. The bug is visible as
black bar right of the subtitle bounding box. Fix by giving libswscale
more alignment. Then the "outside" pixels are inside, and are processed
normally instead of overwritten with black.
NOTE: we do not increase the alignment constant, because this is a
separate issue from pointer alignment. libavutil's av_malloc() wouldn't
actually satisfy the increased alignment either.
The \xFF escape is used internally to insert special OSD symbols (which
need a font change to the internal OSD font). There was potential for
breakage when \xFF was followed by \0, because then "in" would be
advanced past the string's end.
Normally this can't happen, as it would require invalid UTF-8 input
data. But we don't check input for UTF-8 validness, so there's a
potential issue here. Garbled output is ok on invalid UTF-8 input,
but crashing is not.
Make it more robust by checking for this.
append_utf8_buffer() reallocates the buffer passed to it, and returns
the new pointer.
This bug was originally introduced in mplayer2 when that project merged
mpv's osd_libass.c. That merge changed some minor things, including ASS
escape handling. When mpv used this better method of escape handling too
(commit 0ff7dd992f), the bug was duplicated.
Fix spudec change detection. The internal changed-flag was not reset
when retrieving indexed bitmaps, and subtitles were rescaled every
frame, even if they were not changing.
Simplify subtitle decoders by not requiring them to check whether the
passed-in screen size has changed. sd_lavc did this, and spudec would
have needed to do the same. Instead, leave this to the osd_object
force_redraw flag. Subtitle decoders (such as libass) can still signal
that only the positions of subtitles have changed, but making _all_
subtitle decoders do this just to deal with screen size changes is
worthless.
Crop subtitle images produced by spudec.c: instead of returning a frame-
sized bitmap (with possibly large transparent regions), return a cropped
down rectangle of the visible part only. The old spudec scaler code had
this as spudec_cut_image(), but it worked on the data converted to the
old OSD format only.
Move most code to setup the sub-bitmap from spudec_get_indexed() to
spudec_process_data(), so that cropping can be done every time a new
subtitle is decoded, instead of every frame.
Set the sub_bitmaps->scaled flag. Without it, vo_gl and vo_vdpau
produced ugly artifacts on the borders.
Fixes problems with ugly borders.
Note that at least in the DVD sub case, we could have just set all
transparent pixels to black to solve this.
vo_direct3d.c change untested, because mingw is a miserable pile of
crap.
Instead, sd_lavc.c and spudec.c (the two image sub decoders) always
output indexed/paletted images. For this purpose, add SUBBITMAP_INDEXED,
and convert the subs to RGBA in img_convert.c instead. If a VO is used
that supports the old OSD format only, the indexed bitmaps are converted
to the old OSD format by abusing spudec.c in a similar way sd_lavc.c
used to do.
The main reason why spudec.c is used is because the images must not only
be converted to the old format, but also properly scaled, cropped, and
aligned (the asm code in libvo/osd.c requires this alignment).
Remove support for the old format (packed variant) from the OpenGL VOs.
(The packed formats were how the actual OSD format was handled in some
GPU-driven VOs for a while.)
Remove all conversions from old to new formats. Now all subtitle
decoders and OSD renderers produce the new formats only.
Add an evil hack to convert the new format (scaled+indexed bitmaps) to
the old format. It creates a new spudec instance to convert images to
grayscale and to scale them. This is temporary for VOs which don't
support new OSD formats yet (vo_xv, vo_x11, vo_lavc).
Move sub-bitmap definitions from dec_sub.h to sub.h. While it's a bit
odd that OSD data structures are in a file named sub.h, it's definitely
way too strange to have them in a file about subtitle decoding. (Maybe
sub.h/.c and the sub/ directory should be split out and renamed "osd"
at a later point.)
Remove including ass_mp.h (and the libass headers) where possible.
Remove typedefs for mp_eosd_res and sub_bitmaps structs.
Store a mp_eosd_res struct in osd_state instead of just w/h. Note that
sbtitles might be rendered using different sizes/margins when filters
are involved (the subtitle renderer is not supposed to use the OSD res
directly, and the "dim" member removed in the previous commit is
something different).
Passing parameters from caller to subtitle renderer was done by
temporarily setting certain members in the osd_state struct (which for
all practical purposes are as good as global variables). This was the
only purpose of these members.
Rather than using such a messy way to pass parameter, put these into a
struct sub_render_params. The struct was already introduced in earlier
commits, and this commit just removes the parameter passing hack.
Before this commit, vf_vo.c and vf_ass.c were manually calling the
subtitle decoder to retrieve images to render. In particular, this
circumvented the sub-bitmap conversion & caching layer in sub.c.
Change this so that subtitle decoding isn't special anymore, and draws
all subtitles with the normal OSD drawing API.
This is also a step towards removing the need for vf_ass auto-insertion.
In fact, if auto-insertion would be disabled now, VOs with "old" OSD
rendering could still render ASS subtitles in monochrome, because
there is still ASS -> old-OSD bitmap conversion in the sub.c mechanism.
The code is written with the assumption that the subtitle rendering
filter (vf_ass) can render all subtitle formats. Since vf_ass knows the
ASS format only, rendering image subs (i.e. RGBA subs) with it simply
fails. This means that with vo_xv (vf_ass auto-inserted), image subs
wouldn't be rendered. Use a dumb hack to disable rendering subs with a
filter, if we detect that the subs are not in ASS format. (Trying to
render the subs first would probably result in purging the conversion
cache on every frame.)
VOs which could render the OSD in window size (as opposed to video size,
like vo_xv) and which could cache the OSD called this when the window
size changed. This was needed, because VOs used another OSD function to
check whether the OSD changed before passing the new window size to the
OSD code.
This was really just an artifact of OSD change detection, and now that
the affected VOs use the new OSD rendering API, it's done automatically.
This was an extremely obscure setting, as it was used only with vo_gl
if its scaled-osd suboption was used. If you really want this, you can
set the desired ass-hinting value directly, and there will be literally
no loss in functionality.
Note that this didn't actually test whether the EOSD was scaled.
Basically, it only checked whether vo_gl had the scaled-osd suboption
set.
With this commit, the player will still use spudec.c (the "old" DVD sub
decoder), rather than ffmpeg. But it brings the changes needed to enable
this down to a single line change:

Also, copy the DVD resolution heuristics from spudec.c (from the
spudec_new_scaled() function). I'm not sure if this is correct or even
needed, but the sd_lavc codd explicitly reverted back to spudec with
code carrying this comment:
// Assume resolution heuristics only work for PGS and DVB
so it seems likely that the required heuristics were missing, and that
the spudec heuristics may make the DVD compatibility situation at least
as good as with spudec.
Note that it's unlikely that we enable sd_lavc for DVD subs by default,
as there are other problems in combination with direct DVD playback.
We are using libass for OSD rendering. One problem with that is that
libass has to be bug-compatible to VSFilter. This includes the setting
for the default RTL base direction. Neutral would be most reasonable,
but VSFilter assumes LTR.
This commit forces the default to neutral.
Unconfirmed whether this actually works as intended.
See the following libass commits:
9dbd12d shaper: allow font encoding -1 for neutral base direction
a80c45c shaper: always use LTR base direction by default
