* ass_mp: don't use --subcp for --ass-styleswm42014-03-311-1/+1
| | | | | | | | | | | | | The --ass-styles option is implemented by calling ass_read_styles(). This function can take a codepage (so libass will use iconv to convert it). This was implemented before our --subcp option was changed, and this code was not updated. Now libass fails opening iconv, because --subcp is not always (and not by default) a valid iconv codepage. Just always pass NULL, which means the file passed to --ass-styles must be in UTF-8. The --ass-styles option is a fringe option anyway (and will destroy your subtitles), so having codepage support for it isn't important at all.
* Remove some more unneeded version checkswm42014-03-161-5/+1
| | | | | All of these check against things that happened before the latest supported FFmpeg/Libav release.
* sub: remove old MPlayer DVD sub decoderwm42014-03-165-946/+0
| | | | | The DVD sub decoder in Libav 9 was broken/incomplete, so we kept the MPlayer decoder around. Now it's not needed anymore.
* demux_libass: change how external ASS subtitles are loadedwm42014-03-153-15/+5
| | | | | | | | | | Instead of parsing the ASS file in demux_libass.c and trying to pass the ASS_Track to the subtitle renderer, just read all file data in demux_libass.c, and let the subtitle renderer pass the file contents to ass_process_codec_private(). (This happens to parse full files too.) Makes the code simpler, though it also relies harder on the (messy) probe logic in demux_libass.c.
* sub: use new FFmpeg API to check MicroDVD FPSwm42014-03-041-3/+5
| | | | | | Before this, it wasn't possible to distinguish MicroDVD subtitles without FPS header, and subtitles with FPS header equal to FFmpeg's fallback FPS.
* sd_ass: add a very simple and evil way to override ASS subtitle styleswm42014-03-011-0/+27
| | | | | | --ass-style-override=force now attempts to override the 'Default' style. May or may not work. In some situations it will work, but also mess up seemingly unrelated things like signs typeset with ASS.
* sd_lavc: handle subtitles with no subtitle resolution setxylosper2014-02-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | Set subtitle resolution to video resolution when avctx->width and avctx->height are zero. This can happen with broken vobsubs that have no size set in their .idx file (or Matroska extradata). At least with the test file provided in issue #551, using the video resolution as fallback instead of what guess_resolution() does is better. Note that these files clearly are broken. It seems this particular file was created by trying to use ffmpeg to transcode DVB subtitles to vobsub, and ffmpeg "forgot" to set the subtitle resolution in the destination file. On the other hand, ffmpeg DVB and PGS decoders set the resolution on the first subtitle packet (or somewhere close), so it's not really clear what to do here. Closes #551. Signed-off-by: wm4 <wm4@nowhere> Patch by xylosper, rewritten commit message by wm4.
* sub: handle vobsub-in-mp4wm42014-02-133-0/+41
| | | | | | | | | | | The mplayer decoder (spudec.c) actually handled this. There was explicit code for binary palettes (16 32 bit values), and the subtitle resolution was handled by video resolution coincidentally matching the subtitle resolution. Whoever puts vobsub into mp4 should be punished. Fixes the sample gundam_sample.mp4, closes github issue #547.
* threads: add wrapper for initializing recursive mutexeswm42014-01-311-5/+2
| | | | Damn this overly verbose pthread API.
* sd_lavc: skip 0 sized sub-bitmapswm42014-01-291-2/+4
| | | | | | | Not everything in the OSD path handles 0x0 sized sub-bitmaps well. At least the code implementing --sub-gray had severe problems with it. Fix this by skipping such bitmaps.
* sub: fix crash with certain uses of --vf=subwm42014-01-263-32/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | If, for some reason, the subtitle renderer attempts to render a subtitle before SD_CTRL_SET_VIDEO_PARAMS was called, it passed a value calculated from invalid values. This can happen with --vf=sub and --start. The crash happens if 1. there was a subtitle packet that falls into the timestamp of the rendered video frame, 2. the playloop hasn't informed the subtitle decoder about the video resolution yet (normally unneeded, because that is used for weird corner cases only, so this code is a bit fuzzy), and 3. something actually requests a frame to be drawn from the subtitle renderer, like with vf_sub. The actual crash was due to passing NaN as pixel aspect to libass, which then created glyphs with ridiculous sizes, involving a few integer overflows and unchecked mallocs. The sd_lavc.c and sd_spu.c cases probably don't crash, but I'm not sure, and it's better fix them anyway. Not bothering with sd_spu.c, this crap is for compatibility and will be removed soon. Note that this would have been no problem, had the code checked whether SD_CTRL_SET_VIDEO_PARAMS was actually called. This commit adds such a check (although it basically checks after using the parameters). Regression since 49caa0a7 and 633fde4a.
* video/out: don't access aspdat in VOswm42014-01-222-0/+18
| | | | | | | | | | | vo->aspdat is basically an outdated version of vo->params, plus some weirdness. Get rid of it, which will allow further cleanups and which will make multithreading easier (less state to care about). Also, simplify some VO code by using mp_image_set_attributes() instead of caring about display size, colorspace, etc. manually. Add the function osd_res_from_image_params(), which is often needed in the case OSD renders into an image.
* osd: fix dvdnav highlightswm42014-01-181-1/+2
| | | | Broken by previous commit.
* sub: uglify OSD code path with lockingwm42014-01-185-126/+285
| | | | | | | | | | | | | | | Do two things: 1. add locking to struct osd_state 2. make struct osd_state opaque While 1. is somewhat simple, 2. is quite horrible. Lots of code accesses lots of osd_state (and osd_object) members. To make sure everything is accessed synchronously, I prefer making osd_state opaque, even if it means adding pretty dumb accessors. All of this is meant to allow running VO in their own threads. Eventually, VOs will request OSD on their own, which means osd_state will be accessed from foreign threads.
* sub: uglify sub decoder with lockingwm42014-01-173-6/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | | The plan is to make the whole OSD thread-safe, and we start with this. We just put locks on all entry points (fortunately, dec_sub.c and all sd_*.c decoders are very closed off, and only the entry points in dec_sub.h let you access it). I think this is pretty ugly, but at least it's very simple. There's a special case with sub_get_bitmaps(): this function returns pointers to decoder data (specifically, libass images). There's no way to synchronize this internally, so expose sub_lock/sub_unlock functions. To make things simpler, and especially because the lock is sort-of exposed to the outside world, make the locks recursive. Although the only case where this is actually needed (although trivial) is sub_set_extradata(). One corner case are ASS subtitles: for some reason, we keep a single ASS_Renderer instance for subtitles around (probably to avoid rescanning fonts with ordered chapters), and this ASS_Renderer instance is not synchronized. Also, demux_libass.c loads ASS_Track objects, which are directly passed to sd_ass.c. These things are not synchronized (and would be hard to synchronize), and basically we're out of luck. But I think for now, accesses happen reasonably serialized, so there is no actual problem yet, even if we start to access OSD from other threads.
* sd_lavc: use mp_lavc_set_extradata()wm42014-01-111-2/+2
| | | | | This includes the magical input padding required by libavcodec, which we possibly didn't do before this commit.
* sub: fix frame based subtitle timestamp handlingwm42014-01-091-1/+1
| | | | | | Subtitle formats with frame based timing require using the video FPS to compute proper subtitle timestamps. But it looks like the calculation to do that was inversed.
* Fix subtitle delay inversionMartin Herkt2014-01-061-1/+1

* vo: dropping subtitle files on the VO window adds them as subtitle fileswm42014-01-042-0/+9
| | | | | | | Note that we don't try to be clever about detecting the files as subtitles: we just check the file extension. We could go all the way and check the files by opening them with a demuxer, but that would probably do more bad than good.
* osd_libass: use bstr_xappend()wm42013-12-301-22/+25
| | | | Partially, just enough to drop mp_append_utf8_buffer().
* player: add --secondary-sid for displaying a second subtitle streamwm42013-12-243-23/+29
| | | | | | | This is relatively hacky, but it's Christmas, so it's ok. This does two things: 1. allow selecting two subtitle tracks, and 2. include a hack that renders the second subtitle always as toptitle. See manpage additions how to use this.
* msg: rename mp_msg_log -> mp_msgwm42013-12-211-2/+2
| | | | Same for companion functions.
* msg: convert defines to enumwm42013-12-211-2/+2
| | | | Also get rid of MSGL_HINT and the many MSGL_DBG* levels.
* path lookup functions: mp_msg conversionswm42013-12-212-11/+9
| | | | | | | | | | | | | | | | | There's a single mp_msg() in path.c, but all path lookup functions seem to depend on it, so we get a rat-tail of stuff we have to change. This is probably a good thing though, because we can have the path lookup functions also access options, so we could allow overriding the default config path, or ignore the MPV_HOME environment variable, and such things. Also take the chance to consistently add talloc_ctx parameters to the path lookup functions. Also, this change causes a big mess on configfiles.c. It's the same issue: everything suddenly needs a (different) context argument. Make it less wild by providing a mp_load_auto_profiles() function, which isolates most of it to configfiles.c.

* Reduce recursive config.h inclusions in headerswm42013-12-181-0/+1
| | | | | | In my opinion, config.h inclusions should be kept to a minimum. MPlayer code really liked including config.h everywhere, though, even in often used header files. Try to reduce this.
* Split mpvcore/ into common/, misc/, bstr/wm42013-12-1713-24/+24
|
* Move options/config related files from mpvcore/ to options/wm42013-12-179-11/+11
| | | | | | | | | Since m_option.h and options.h are extremely often included, a lot of files have to be changed. Moving path.c/h to options/ is a bit questionable, but since this is mainly about access to config files (which are also handled in options/), it's probably ok.
* Replace mp_tmsg, mp_dbg -> mp_msg, remove mp_gtext(), remove set_osd_tmsgwm42013-12-161-2/+2
| | | | | | | | | The tmsg stuff was for the internal gettext() based translation system, which nobody ever attempted to use and thus was removed. mp_gtext() and set_osd_tmsg() were also for this. mp_dbg was once enabled in debug mode only, but since we have log level for enabling debug messages, it seems utterly useless.
* osd_libass: update styles when OSD changes PlayReswm42013-12-152-8/+15
| | | | | | | The OSD style settings depend on the PlayRes, simply because all style values are implicitly scaled by the PlayResY in libass. Also, the OSC changes the PlayResY in certain situations, so something could go wrong. But not sure if this actually matters in practice.
* osd: use separate ASS_Renderer for each OSD objectwm42013-12-153-46/+53
| | | | | | | | This simplifies things, although it is slightly less efficient (probably uses a bit more memory). This also happens to fix that the OSC dropped the libass cache on every frame.
* player: don't store subtitle renderer in osd_statewm42013-12-152-5/+2
| | | | | | | | This doesn't have much value. It can't be accessed by anything else than the actual subtitle renderer (sd_ass.c). sd_ass.c could create the renderer itself, except that we apparently want to save memory (and some font loading time) when using ordered chapters or multiple subtitle tracks.
* dvdnav: support mouse interactionwm42013-12-132-0/+20
|
* Add prelimimary (basic, possibly broken) dvdnav supportwm42013-12-124-4/+26
| | | | | | | | | | | | | | | | | | | | | | | | | This readds a more or less completely new dvdnav implementation, though it's based on the code from before commit 41fbcee. Note that this is rather basic, and might be broken or not quite usable in many cases. Most importantly, navigation highlights are not correctly implemented. This would require changes in the FFmpeg dvdsub decoder (to apply a different internal CLUT), so supporting it is not really possible right now. And in fact, I don't think I ever want to support it, because it's a very small gain for a lot of work. Instead, mpv will display fake highlights, which are an approximate bounding box around the real highlights. Some things like mouse input or switching audio/subtitles stream using the dvdnav VM are not supported. Might be quite fragile on transitions: if dvdnav initiates a transition, and doesn't give us enough mpeg data to initialize video playback, the player will just quit. This is added only because some users seem to want it. I don't intend to make mpv a good DVD player, so the very basic minimum will have to do. How about you just convert your DVD to proper video files?

* av_common: add timebase parameter to mp_set_av_packet()wm42013-12-041-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | If the timebase is set, it's used for converting the packet timestamps. Otherwise, the previous method of reinterpret-casting the mpv style double timestamps to libavcodec style int64_t timestamps is used. Also replace the kind of awkward mp_get_av_frame_pkt_ts() function by mp_pts_from_av(), which simply converts timestamps in a way the old function did. (Plus it takes a timebase parameter, similar to the addition to mp_set_av_packet().) Note that this should not change anything yet. The code in ad_lavc.c and vd_lavc.c passes NULL for the timebase parameters. We could set AVCodecContext.pkt_timebase and use that if we want to give libavcodec "proper" timestamps. This could be important for ad_lavc.c: some codecs (opus, probably mp3 and aac too) have weird requirements about doing decoding preroll on the container level, and thus require adjusting the audio start timestamps in some cases. libavcodec doesn't tell us how much was skipped, so we either get shifted timestamps (by the length of the skipped data), or we give it proper timestamps. (Note: libavcodec interprets or changes timestamps only if pkt_timebase is set, which by default it is not.) This would require selecting a timebase though, so I feel uncomfortable with the idea. At least this change paves the way, and will allow some testing.
* sub: respect detected language for fuzzy-matched external subtitleswm42013-11-252-15/+17
| | | | | | | Solve this by passing through the language to the player, which then uses the generic subtitle selection code to make a choice. Fixes #367.
* osd: remove mp_osd_res.video_par fieldwm42013-11-242-3/+1
| | | | | | This is not needed anymore, because we decided that the PAR of the decoded video matters, and not the PAR of the filtered video that arrives at the VO.
* Rename sub.c/.h to osd.c/.hwm42013-11-2415-16/+10
| | | | | This was way too misleading. osd.c merely calls the subtitle renderers, instead of actually dealing with subtitles.
* Reduce stheader.h includes, move stream types to mp_common.hwm42013-11-232-2/+0
|
* player: rearrange how subtitle context and stream headers are usedwm42013-11-232-15/+17
| | | | | | | | | | | | Use sh_stream over sh_sub. Use dec_sub (and mpctx->d_sub) instead of the stream header. This aligns the subtitle code with the recent audio and video refactoring. sh_sub still has the decoder context, though. This is because we want to avoid reinit when switching segments with ordered chapters. (Reinit is fast, except for creating the ASS_Renderer, which in turn triggers fontconfig.) Not sure how much this matters, though, because the initial segment switch will lazily initialize the decoder anyway.
* demux: rename demux_packet.h to packet.hwm42013-11-181-1/+1
| | | | This always bothered me.
* sd_lavc, sd_spu: make dvdsub stretching conditional on --stretch-dvd-subs.Rudolf Polzer2013-11-074-8/+40
| | | | | | | | | | | | We found that the stretching - although it usually improves the looks of the fonts - is incorrect. On DVD, subtitles can cover the full area of the picture, and they have the same pixel aspect as the movie itself. Too bad many commercially released DVDs use bitmap fonts made with the wrong pixel aspect (i.e. assuming 1:1) - --stretch-dvd-subs will make these more pretty then.
* sd_ass, sd_lavc: use the input video's pixel aspect for scaling subtitles.Rudolf Polzer2013-11-072-4/+25
| | | | | | | The previous code used the output video's pixel aspect for stretching purposes, breaking rendering with e.g. -vf scale in the chain. Now subtitles are stretched using the input video's pixel aspect only, matching the intentions of the original subtitle author.
* configure: uniform the defines to #define HAVE_xxx (0|1)Stefano Pigozzi2013-11-032-3/+3
| | | | | | | | | | | | | | | | | | | | | 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.

* sd_lavc: display DVD subs with unknown durationwm42013-10-311-0/+6
| | | | | | | | | | | | | | | | | | DVD subs (rarely) have subtitle events without end timestamp. The duration is unknown, and they should be displayed until they're replaced by the next event. FFmpeg fails hard to make us aware whether duration is unknown or actually 0, so we can't distinguish between these two cases. It fails at this twice: AVPacket.duration is set to 0 if duration is unknown, and AVSubtitle.end_display_time has the same issue. Add a hack that considers all bitmap subtitles with duration==0 as events with uknown length. I'd rather accidentally display a hidden subtitle (if they exist at all), instead of not displaying random subtitles at all. See github issue #325.
* command: sub_seek: avoid getting stuckwm42013-10-071-2/+5
| | | | | | | | | First, don't try to seek if the result is 0 (i.e. nothing found, or subtitle event happens to be exactly on spot). Second, since we never can make sure that we actually seek to the exact subtitle PTS (seeking "snaps" to video PTS), offset the seek by 10ms. Since most subtitle events are longer than 10ms, this should work fine.
* command: add commands for displaying overlayswm42013-10-052-0/+8
| | | | | | Requested by github issue #255. Does not work where mmap is not available (i.e. Windows).
* command: add properties for retrieving OSD dimensionswm42013-10-052-0/+5
|
* osd_libass: add "Default" dummy stylewm42013-09-263-2/+11
| | | | | | 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.
* Add initial Lua scripting supportwm42013-09-264-0/+70
| | | | | | | | | | | | | | | | | | | | | | This is preliminary. There are still tons of issues, and any aspect of scripting may change in the future. I decided to merge this (preliminary) work now because it makes it easier to develop it, not because it's done. lua.rst is clear enough about it (plus some sarcasm). This requires linking to Lua. Lua has no official pkg-config file, but there are distribution specific .pc files, all with different names. Adding a non-pkg-config based configure test was considered, but we'd rather not. One major complication is that libquvi links against Lua too, and if the Lua version is different from mpv's, you will get a crash as soon as libquvi uses Lua. (libquvi by design always runs when a file is opened.) I would consider this the problem of distros and whoever builds mpv, but to make things easier for users, we add a terrible runtime test to the configure script, which probes whether libquvi will crash. This is disabled when cross-compiling, but in that case we hope the user knows what he is doing.
* options: allow selecting the libass shaperwm42013-09-251-0/+3
| | | | | | I'm using the word "languages" instead of "scripts" in the manpage, but I think that's easier to understand with a smaller amount of descriptions.
* options: make --ass-hinting a choice, instead of using magic numberswm42013-09-251-1/+1
| | | | | options.c still doesn't use the constants defined by the libass headers, but it's still better than exposing those to the user directly.
* sd_ass: minor simplificationwm42013-09-241-14/+8
| | | | | There shouldn't be any functional changes. Just reduce the amount of pointless temporary variables.
* sd_ass: remove dead codewm42013-09-241-48/+0
