* command: extend osd-overlay command with bounds reportingwm42020-03-061-0/+2
| | | | | | | | | | | | | | | | | | | | 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.
* ass_mp: change license to LGPLwm42017-04-201-7/+7
| | | | | | | Somewhat chaostic history: libass/ass_mp.* -> ass_mp.* -> sub/ass_mp.* As far as I can tell, everyone who ever touched these files has agreed to the relicensing.
* sub: pack libass bitmaps directly in sd_ass.c and osd_libass.cwm42016-06-301-3/+5
| | | | | | | | | | | | | | | | Change all producer of libass images to packing the bitmaps into a single larger bitmap directly when they're output. This is supposed to help working towards refcounted sub bitmaps. This will reduce performance for VOs like vo_xv, but not for vo_opengl. vo_opengl simply will pick up the pre-packed sub bitmaps, and skip packing them again. vo_xv will copy and pack the sub bitmaps unnecessarily - but if we want sub bitmap refcounting, they'd have to be copied anyway. The packing code cannot be removed yet from vo_opengl, because there are certain corner cases that still produce unpackad other sub bitmaps. Actual refcounting will also require more work.
* ass_mp.h: remove conditional inclusion guardswm42016-06-241-6/+2
| | | | | This file is only used when libass is enabled. (It used to be different, when code was more entangled.)
* osd: refactor how mp_ass_render_frame() is calledwm42016-03-081-1/+1
| | | | | | | | Instead of passing an explicit cache to the function, the res parameter is used. Also, instead of replacing its contents, sub bitmaps are now appended to it (all assuming the format doesn't actually change). This is preparation for the following commits.

* sub: remove unused function, move another onewm42015-11-291-4/+0
| | | | | mp_ass_default_track() was not used by anything anymore (commit 5a89150a got rid of it). mp_ass_add_default_styles() is used by sd_ass.c only.

* sub: move mp_ass_configure() codewm42015-02-241-3/+0
| | | | | sd_ass.c is the only user, and the function is starting to become extremely "special". No other changes.
* sub: mess with styling defaults, change --ass-use-margins behaviorwm42015-02-161-1/+1
| | | | | | | | | | | | | | | | | | | 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.
* sub: fix undefined behavior in ASS color calculationwm42014-05-101-1/+1
| | | | | | | This might shift bits into the sign, which is undefined behavior. Making the right operand unsigned was supposed to help with this, but it seems it did nothing, and C99 makes the result type dependent on the left operand only.

* configure: uniform the defines to #define HAVE_xxx (0|1)Stefano Pigozzi2013-11-031-2/+2
| | | | | | | | | | | | | | | | | | | | | The configure followed 5 different convetions of defines because the next guy always wanted to introduce a new better way to uniform it[1]. For an hypothetic feature 'hurr' you could have had: * #define HAVE_HURR 1 / #undef HAVE_DURR * #define HAVE_HURR / #undef HAVE_DURR * #define CONFIG_HURR 1 / #undef CONFIG_DURR * #define HAVE_HURR 1 / #define HAVE_DURR 0 * #define CONFIG_HURR 1 / #define CONFIG_DURR 0 All is now uniform and uses: * #define HAVE_HURR 1 * #define HAVE_DURR 0 We like definining to 0 as opposed to `undef` bcause it can help spot typos and is very helpful when doing big reorganizations in the code.

* osd_libass: add "Default" dummy stylewm42013-09-261-1/+2
| | | | | | This is pretty much a hack for the OSC. It will allow it to rely on a somewhat predictable style, instead of having to overwrite all user OSD settings manually with override tags.
* sub: add demux_libass wrapper, drop old hackswm42013-06-251-2/+0
| | | | | | | | | | | | demux_libass.c allows us to make subtitle format detection part of the normal file loading process. libass has no probe function, but trying to load the start of a file (the first 4 KB) is good enough. Hope that libass can even handle random binary input gracefully without printing stupid log messages, and that the libass parser doesn't accept too many non-ASS files as input. This doesn't handle the -subcp option correctly yet. This will be fixed later.

* sd_srt, sd_microdvd: set ASS script resolutionwm42013-06-031-1/+2
| | | | | | | | | | | | | | | | | Both converters can output \pos and deal with font sizes, so they assume a specific script resolution (PlayResX/PlayResY). The implicit assumption was that a specific resolution was guaranteed. The MP_ASS_FONT_PLAYRESY constant is connected to this. Better make it explicit, so that the implicit dependency on MP_ASS_FONT_PLAYRESY is removed. (Unfortunately, libavcodec sub converters still don't set PlayResX/PlayResY explicitly, so the value set by that constant can't be declared as arbitrary yet.) PlayResY=288 is most likely the SSA natural script resolution (or something like this?), as well as the libass and VSFilter default. PlayResX=384 is the fallback value set by libass if PlayResY is set to 288, and PlayResX is unset.

* sub: turn subassconvert_ functions into sub converterswm42013-06-031-2/+0
| | | | | | | | | | | | | | | | | This means subassconvert.c is split in sd_srt.c and sd_microdvd.c. Now this code is involved in the sub conversion chain like sd_movtext is. The invocation of the converter in sd_ass.c is removed. This requires some other changes to make the new sub converter code work with loading external subtitles. Until now, subtitles loaded via subreader.c was assumed to be in plaintext, or for some formats, in ASS (except in -no-ass mode). Then these were added to an ASS_Track. Change this so that subtitles are always in their original format (as far as decoders/converters for them are available), and turn every sub event read by subreader.c as packet to the dec_sub.c subtitle chain. This removes differences between external/demuxed and -ass/-no-ass code paths further.

* osd: make the OSD and sub font more customizablewm42012-11-201-1/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* VO, sub: refactorwm42012-10-241-3/+3
| | | | | | | | | | | | | | | | | | 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.
* sub: remove logic for disabling hinting on scaled EOSDwm42012-10-161-1/+1
| | | | | | | | | | | 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.
* sub: allow rendering OSD in ASS image format directly, simplifywm42012-10-161-0/+5
| | | | | | | | | | | | | | | | | | | | | Before this commit, the OSD was drawn using libass, but the resulting bitmaps were converted to the internal mplayer OSD format. We want to get rid of the old OSD format, because it's monochrome, and can't even be rendered directly using modern video output methods (like with OpenGL/Direct3D/VDPAU). Change it so that VOs can get the ASS images directly, without additional conversions. (This also has the consequence that the OSD can render colors now.) Currently, this is vo_gl3 only. The other VOs still use the old method. Also, the old OSD format is still used for all VOs with DVD subtitles (spudec). Rewrite sub.c. Remove all the awkward flags and bounding boxes and change detection things. It turns out that much of that isn't needed. Move code related to converting subtitle images to img_convert.c. (It has to be noted that all of these conversions were already done before in some places, and that the new code actually makes less use of them.)
* subs: always use sub decoder framework for libass renderingUoti Urpala2012-09-181-6/+0
| | | | | | | | | | | | | | | | | | | | | Remove subtitle selection code setting osd->ass_track directly and vf_ass/vf_vo code rendering the track directly with libass. Instead, do track selection and rendering with dec_sub.c functions. Before, mpctx->set_of_ass_tracks[] contained bare libass tracks generated from external subtitle files. For use with dec_sub.c, it now contains struct sh_sub instances with decoder already initialized. This commit breaks the sub_step command ('g' and 'y' keys) for libass-rendered subtitles. It could be fixed, but it's so useless - especially as with the existing implementation there's no practical way to get subtitle delay back to normal after using it - that I didn't bother.

* subs: libass: use a single persistent renderer for subtitlesUoti Urpala2012-09-181-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To draw libass subtitles, the code used ASS_Renderer objects created in vf_vo (VO rendering) or vf_ass. They were destroyed and recreated together with the video filter chain. Change the code to use a single persistent renderer instance stored in the main osd_state struct. Because libass seems to misbehave if fonts are changed while a renderer exists (even if ass_set_fonts() is called on the renderer afterwards), the renderer is recreated after adding embedded fonts. The known benefits are simpler code and avoiding delays when switching between timeline parts from different files (libass fontconfig initialization, needed when creating a new renderer, can take a long time in some cases; switching between files rebuilds the video filter chain, and this required recreating the renderers). On the other hand, I'm not sure whether this could cause inefficient bitmap caching in libass; explicitly resetting the renderer in some cases could be beneficial. The new code does not keep the distinction of separate renderers for vsfilter munged aspect vs normal; this means that changing subtitle tracks can lose cache for the previous track. The new code always sets some libass parameters on each rendering call, which were previously only set if they had potentially changed. This should be harmless as libass itself has checks to see if the values differ from previous ones. Conflicts: command.c libmpcodecs/vf_ass.c libmpcodecs/vf_vo.c mplayer.c sub/ass_mp.c

* subs: libass: apply option changes to all track typesUoti Urpala2011-08-081-2/+1
| | | | | | | | | Libass rendering uses two renderer objects to support both VSFilter aspect ratio (mis)behavior emulation and correct rendering. When option values were changed during playback the changes were applied to the renderer used for the currently active track only, and old values could be used if the user then switched to a track using the other renderer object. Fix to update both renderers.

* subs: fix per-file --ass-force-styleUoti Urpala2011-07-231-1/+0
| | | | | | | | | | | | | The --ass-force-style option was only applied when the main libass library handle was created. Thus any per-file option changes later had no effect. Do the ass_set_style_overrides() call in per-file initialization instead so that possible changes will be applied. Also move the option variable to the option struct. Current libass will crash (usually) if you set style overrides to a nonempty value, then an empty one. It'll be easier to trigger this bug after this commit, but the problem is not on mplayer2 side. The fix is trivial so hopefully there will be a fixed libass soon.
