* lavc_conv: make disable_styles fasterOleg Oshmyan2017-10-301-2/+3
| | | | | | | | | | | | | | The current invocation of bstr_cut is as good as no cutting at all. Almost the entire header is reread in every iteration of the loop. I don't know how many styles libavcodec tends to generate, but if (now or in the future) it generates many, then this loop is slow for no good reason. If anything, the code would be more clear and have the same performance if it didn't call bstr_cut at all. The intention here (and the sensible thing regardless) seems to be to skip the part of the string that bstr_find has already looked through and found nothing. This commit additionally skips the whole substring, because overlapping matches are impossible.
* lavc_conv: clamp timestamps to positive, fixes idiotic ffmpeg issuewm42017-10-271-0/+2
| | | | | | | | | | | In some cases, demux_mkv will detect a start time slightly above 0, but there might still be a subtitle starting at exactly 0. When the player rebases the timestamps to assumed start time, the subtitle will have a slightly negative timestamp in the end. libavcodec's subtitle converter turns this into a larger number due to underflow. Fix by clamping subtitles always to 0, which may or may not be what you want. At least it fixes #5047.
* lavc_conv: pass pkt_timebase to ffmpegAman Gupta2017-02-181-0/+3
| | | | Similar to code used everywhere else we create a lavc context.
* Remove compatibility thingswm42016-12-071-3/+0
| | | | | | Possible with bumped FFmpeg/Libav. These are just the simple cases.
* sub: interpret "text" subtitles as srtwm42016-04-061-0/+3
| | | | | Most players will interpret HTML-style tags (aka srt) in almost any kind of text subtitles; make mpv do this too.
* lavc_conv: fix Libav srt subtitleswm42016-02-291-4/+1
| | | | | | | | Use the mp_lavc_set_extradata() function instead of setting up the extradata manually. This takes care of the corner case when extradata_len is 0. This apparently fixes #2888.
* Relicense some non-MPlayer source files to LGPL 2.1 or laterwm42016-01-191-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This covers source files which were added in mplayer2 and mpv times only, and where all code is covered by LGPL relicensing agreements. There are probably more files to which this applies, but I'm being conservative here. A file named ao_sdl.c exists in MPlayer too, but the mpv one is a complete rewrite, and was added some time after the original ao_sdl.c was removed. The same applies to vo_sdl.c, for which the SDL2 API is radically different in addition (MPlayer supports SDL 1.2 only). common.c contains only code written by me. But common.h is a strange case: although it originally was named mp_common.h and exists in MPlayer too, by now it contains only definitions written by uau and me. The exceptions are the CONTROL_ defines - thus not changing the license of common.h yet. codec_tags.c contained once large tables generated from MPlayer's codecs.conf, but all of these tables were removed. From demux_playlist.c I'm removing a code fragment from someone who was not asked; this probably could be done later (see commit 15dccc37). misc.c is a bit complicated to reason about (it was split off mplayer.c and thus contains random functions out of this file), but actually all functions have been added post-MPlayer. Except get_relative_time(), which was written by uau, but looks similar to 3 different versions of something similar in each of the Unix/win32/OSX timer source files. I'm not sure what that means in regards to copyright, so I've just moved it into another still-GPL source file for now. screenshot.c once had some minor parts of MPlayer's vf_screenshot.c, but they're all gone.
* lavc_conv: pass real_time=1 option to ffmpeg for eia_608 decoderAman Gupta2016-01-181-1/+7

* sub: fix memory leakswm42016-01-181-3/+6
| | | | | | | | | demux_lavf.c leaked the complete subtitle data if it was put through iconv. lavc_conv.c leaked AVCodecContext.subtitle_header (set by libavcodec), which is fixed by using avcodec_free_context(). It also leaked the subtitle that was decoded last.
* mpv_talloc.h: rename from talloc.hDmitrij D. Czarkoff2016-01-111-1/+1
| | | | This change helps avoiding conflict with talloc.h from libtalloc.
* sub: refactor initializationwm42015-12-271-9/+0
| | | | | | | | Just simplify by removing parts not needed anymore. This includes merging dec_sub allocation and initialization (since things making initialization complicated were removed), or format support queries (it simply tries to create a decoder, and if that fails, tries the next one).
* lavc_conv: fix invalid writewm42015-12-191-3/+2
| | | | | Well shit. Restructure it such that the returned list is always NULL- terminated with the same mechanism.
* sub: rename sd_lavc_conv.c to lavc_conv.cwm42015-12-181-0/+280
The previous commit turned sd_lavc_conv from a sd_driver to free-standing functions. Do the rename to reflect this change separately to avoid confusing git's content tracking. (Or did git solve this, making separating renames and content changes unnecessary?)
