* sub, demux: identify subtitle types with the codec namewm42013-04-201-0/+1
| | | | | | | | | Get rid of the 1-char subtitle type field. Use sh_stream->codec instead just like audio and video do. Use codec names as defined by libavcodec for simplicity, even if they're somewhat verbose and annoying. Note that ffmpeg might switch to "ass" as codec name for ASS, so we don't bother with the current silly "ssa" name.
* VO, sub: refactorwm42012-10-241-5/+2
| | | | | | | | | | | | | | | | | | 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: cleanup: don't pass parameters via global variableswm42012-10-161-0/+2
| | | | | | | | | | | 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.
* subs: always use sub decoder framework for libass renderingUoti Urpala2012-09-181-0/+3
| | | | | | | | | | | | | | | | | | | | | 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
* sd_lavc: use subtitle framework for former av_sub.c codeUoti Urpala2012-09-181-1/+1
| | | | | | | | | | | | | | | | Change libavcodec subtitle decoding code (used for some bitmap subtitle types) to use the same decoding framework as sd_ass. The functionality that was previously in av_sub.c and was directly called from mplayer.c is now in sd_lavc.c. Conflicts: mplayer.c sub/av_sub.h sub/sd_lavc.c Merged from mplayer2. The remaining use of is_av_sub() is replaced by a check whether a subtitle decoder is active, which should give the same results.
* subtitles: add framework for subtitle decodersUoti Urpala2011-01-181-0/+16
Add a framework for subtitle decoder modules that work more like audio/video decoders do, and change libass rendering of demuxed subtitles to use the new framework. The old subtitle code is messy, with details specific to handling particular subtitle types spread over high-level code. This should make it easier to clean things up and fix some bugs/limitations.
