* sub: add ASS to RGBA conversionwm42012-12-281-2/+2
| | | | | This makes implementing new VOs easier, because they don't have to support the ASS format.
* subs: remove --utf8, simplify codeUoti Urpala2012-12-031-2/+0
| | | | | | | | | | | | | | | | | | | Remove the options --utf8 and --unicode which had no effect any more (what they once did should be doable with --subcp). The only use of corresponding variables left in code was subreader.c code using sub_utf8 as a flag indicating whether iconv conversion was active. Change the code to test the existence of iconv context instead. Conflicts: DOCS/man/en/options.rst core/cfg-mplayer.h sub/sub.c sub/sub.h sub/subreader.c Merged from mplayer2 commit ea7311. Note: --unicode was already removed
* osd: fix z-order of subtitle OSD elementswm42012-11-221-2/+3
| | | | Subs should always be below OSD (meaning they have to be drawn first).
* vo_xv: don't require frame stepping to remove OSD or subswm42012-11-211-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* osd: make the OSD and sub font more customizablewm42012-11-201-4/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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
* screenshot, draw_bmp: use colorspace passed with mp_imagewm42012-11-011-3/+1
| | | | | Remove the explicit struct mp_csp_details parameters from all related functions, and use mp_image.colorspace/levels instead.
* draw_bmp: cosmetics, refactorwm42012-10-281-2/+2
| | | | | | | | | | | 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.
* options: remove --ffactor switchwm42012-10-241-1/+0
| | | | | | | 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.
* options: remove --subfont-autoscale (changes default font scale)wm42012-10-241-1/+0
| | | | | | | | | 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.
* options: remove subtitle related options that did nothingwm42012-10-241-15/+2
| | | | | | | 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.
* sub: add clarifying commentswm42012-10-241-1/+3

* sub: simplify OSD redrawing logicwm42012-10-241-2/+2
| | | | | | | | | | | | | 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.
* VO, sub: refactorwm42012-10-241-16/+10
| | | | | | | | | | | | | | | | | | 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: add cache to mp_draw_sub_bitmaps()wm42012-10-241-1/+3
| | | | This caches scaled RGBA sub-bitmaps.
* sub, vf_ass: allow rendering RGBA subs, replace old vf_ass renderingwm42012-10-241-6/+11
| | | | | | | | | | 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.
* sub: fix text subtitle aspect ratio with vo_xv and vo_lavc, refactorwm42012-10-241-0/+2
| | | | | | | | | | | | | | | | | | | 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.
* Remove things related to old OSDwm42012-10-241-24/+0
| | | | | | | | | | | | | | | 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.
* sub: add function to draw OSD into an imagewm42012-10-241-0/+6
| | | | | | | | 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.
* sub: switch to premultiplied alphawm42012-10-161-1/+1
| | | | | | | | | | 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.
* sub: never decode subs to old OSD formatwm42012-10-161-7/+17
| | | | | | | | | | | | | | | | | | | | | | | | | 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).
* sub: cosmetics: move things aroundwm42012-10-161-2/+55
| | | | | | | | | | | | | | | | | | 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).
* sub: cleanup: don't pass parameters via global variableswm42012-10-161-7/+1
| | | | | | | | | | | 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.
* sub: always go through sub.c for OSD renderingwm42012-10-161-2/+12
| | | | | | | | | | | | | | | | | | | | | | | 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.)
* sub, VO: remove vo_osd_resized() functionwm42012-10-161-1/+0
| | | | | | | | | | | 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.
* sub: remove logic for disabling hinting on scaled EOSDwm42012-10-161-1/+0
| | | | | | | | | | | 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 converting DVD subs to RGBAwm42012-10-161-1/+1
| | | | | | | | | | | | | | The mplayer DVD sub decoder is the only remaining OSD image producer that still requires the old mplayer OSD format (SUBBITMAP_OLD_PLANAR). To make supporting this format optional in VOs, add a step that allows converting these images to RGBA in case the VO doesn't have direct support for it. Note: the mplayer DVD sub decoder uses the old mplayer OSD format (SUBBITMAP_OLD_PLANAR), which is assumed to use premultiplied alpha. However, it seems DVDs allow only binary transparency, so the rendered result will be the same.
* sub: allow rendering OSD in ASS image format directly, simplifywm42012-10-161-46/+37
| | | | | | | | | | | | | | | | | | | | | 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.)
* sub: add preliminary emulation layer to draw OSD with EOSDwm42012-10-161-0/+9
| | | | | | | | | This basically pushes the old OSD bitmaps via VOCTRL_DRAW_EOSD to the VO, instead of using the old callback-based interface. Future commits will change the code such that sub.c pushes images rendered by libass directly, rather than converting them to the old OSD format first.
* subs, vo_vdpau: support RGBA color for PGS subtitlesUoti Urpala2012-09-181-0/+1
| | | | | | | | | | | | | | | | | | | | | | Support passing bitmap subtitles to VOs in full RGBA color, and implement this for libavcodec-decoded subtitle formats on decoding side and vo_vdpau on display side. Currently this is enabled for PGS (blu-ray) and DVB subtitles. VDPAU seems to have sampling issues similar to known GL ones when drawing a sub-rectangle from a larger texture with scaling, where adjacent pixels outside the specified source rectangle affect the result. As the bitmap subtitles may be scaled, add padding support to the bitmap packer code. In principle, this could be used for colored DVD subtitles too. However, the libavcodec DVD decoder lacks parts of the resolution and palette handling that are present in spudec.c. Conflicts: libvo/vo_gl.c sub/dec_sub.h sub/sd_lavc.c
* options: remove -subalignwm42012-09-181-1/+0
| | | | | | It can't be re-implemented, because this isn't supported by libass. The -subalign option and the associated sub-align slave property did nothing. Remove them.
* subs, vo: do sub bitmap change detection by comparing IDsUoti Urpala2012-09-181-1/+2
| | | | | | | | | | | | | | | | | vo_vdpau and vo_gl cache the last subtitle bitmaps uploaded to video card in case they stay the same over multiple frames. Detecting whether the bitmaps have changed and should be re-uploaded was somewhat fragile. Change the VO API to provide a bitmap ID which can be compared with what the VO has to determine whether a new upload of the bitmaps is needed. Conflicts: libvo/vo_gl.c Note: the changes for vo_gl.c were not merged. Instead, eosd_packer is modified to use the new way of detecting EOSD changes. This takes care of vo_gl, vo_gl3 and vo_direct3d, which all render EOSD. They don't need to be updated in turn.
* subs: always use sub decoder framework for libass renderingUoti Urpala2012-09-181-6/+9
| | | | | | | | | | | | | | | | | | | | | 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. Conflicts: command.c mp_core.h mplayer.c
* subs: libass: use a single persistent renderer for subtitlesUoti Urpala2012-09-181-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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

* Remove dvdnav support (DVD menus)wm42012-08-161-6/+0
| | | | | | | | | | | | | | | | When the internal mplayer MPEG demuxer was removed (commit 1fde09db), the default demuxer when using dvdnav was set to libavformat. Now it turns out that this doesn't work with libavformat. It will terminate playback right after the audio runs out (instead of looping it like the video, or whatever it's supposed to do). I'm not sure what exactly the problem is, but since 1. even mplayer-svn can't handle DVD menus directly (missing highlights), 2. DVD menus are essentially worthless, and 3. I don't directly watch DVDs, don't bother with it and remove it. For basic playback, there's still libdvdread support. Also, use pkg-config for libdvdread, and drop support for in-tree libdvdread. Remove support for in-tree libdvdcss as well.
* sub: fix confusion of ass_library handleswm42012-08-071-3/+5
| | | | | | | | | | | | Commit 7484ae8e2ee5327 attempted to introduce two ass_library handles (as it was needed to deal with how ass_library manages fonts), but the commit was completely bogus: it assumed osd_state->ass_library would be used by osd_libass.c only, which is not the case. As result, some of the subtitle code used the wrong ass_library handle. We need two ass_library handles in osd_state. The one from the mplayer core for subtitles (osd_state->ass_library), and one for OSD rendering (osd_state->osd_ass_library).
* osd_libass: allocate separate ASS_Library for OSDwm42012-08-071-1/+1
| | | | | | | | | | osd_libass.c used the same ASS_Library object as the player core. This caused a problem: when playing a new file, all fonts loaded by the ASS_Library object were unloaded, including the OSD font. Parts of the OSD would stop being rendered correctly. Solve this by creating a separate ASS_Library, with its own set of fonts.
* osd: reset OSD change state even if VO doesn't draw OSDwm42012-08-071-0/+1
| | | | | | | | | | | | Commit 168293e0ae6f08 assumed the OSD drawing routines (which have the functions osd_draw_text/_ext as entrypoint) would always be called, and relied on that to reset the change flag. Some VOs, such as vo_null, didn't do this. Pausing could turn into endless framestepping in some cases. Restore the part of the OSD drawing logic that dealt with this. (Alternatively, the VOs could be obliged to always call the OSD drawing routines, even if the VO doesn't actually draw the OSD. But it seems even more messy to rely on that.)
* VO: remove old VO gluewm42012-08-071-5/+0
| | | | | | | This transition to a new VO API started over 4 years ago. It's time to finally end it, and get rid of the horrible hacks. Also removes some previously undetected dead code from spudec.c.
* Remove teletext supportwm42012-08-031-7/+0
| | | | | | | | Teletext requires special OSD support. Because I can't even test teletext, I can't restore support for it. Since teletext can be considered ancient and obscure, and since it doesn't make sense to keep the remaining teletext code without being able to use it, I'm removing it.
* osd: minor simplification of vo_osd_changed()wm42012-08-011-1/+2
| | | | | | | | | | | | | | | | | | vo_osd_changed() was a weird function: it was used both to query and mutate state, which is a bad combination. The VOs used it to query and reset the state, and the mplayer frontend mostly used it to set the state. In some cases, the frontend did both (that code used a variable "int hack" to backup the state and set it again). Simplify it and make the VOs use a vo_osd_has_changed() function to query whether the OSD bitmaps have to be recreated. vo_osd_changed() on the other hand is now used to update state only. The OSD change state is reset when osd_draw_text()
