* sub: create sub_bitmap array even when using libasswm42012-10-161-1/+2
| | | | | | | | | | | | | | One sub_bitmaps struct could contain either a libass ASS_Image list, or a mplayer native list of sub-bitmaps. This caused code duplication in vo_vdpau.c and bitmap_packer.c. Avoid this by creating such a sub_bitmap array even with libass. This basically copies the list and recreates it in mplayer's native format. It gets rid of the code duplication, and will make implementing extended subtitle and OSD rendering in other VOs easier. Also do some cosmetic changes and other preparations for the following commits.
* subs, vo_vdpau: support RGBA color for PGS subtitlesUoti Urpala2012-09-181-1/+2
| | | | | | | | | | | | | | | | | | | | | | 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
* subs, vo: do sub bitmap change detection by comparing IDsUoti Urpala2012-09-181-6/+13
| | | | | | | | | | | | | | | | | 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 Urpala2012-09-181-3/+26
| | | | | | | | | | | | | | | | | | | | | 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/+5
| | | | | | | | | | | | | | | | 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/+72
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.
