	string length could theoretically be larger than int Reviewed-by: Clément Bœsch <u@pkh.me> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
2014-10-29	Print a warning if a subtitle demuxer changes utf16 to utf8.	Carl Eugen Hoyos
	This does not fix anything but gives users a chance to know that they must not pass -sub_charenc UTF-16 to ffmpeg. Fixes ticket #4059.
2014-09-06	avformat/realtextdec: UTF-16 support	wm4
	Also remove ff_smil_extract_next_chunk - this was the last user of it.
2014-09-06	avformat/samidec: UTF-16 support	wm4
	ff_smil_extract_next_chunk() is still used by RealText.
2014-09-06	avformat/srtdec: UTF-16 support	wm4

2014-09-06	avformat/assdec: UTF-16 support	wm4
	Use the UTF-16 BOM to detect UTF-16 encoding. Convert the file contents to UTF-8 on the fly using FFTextReader, which acts as converting wrapper around AVIOContext. It also can work on a static buffer, needed for format probing. The FFTextReader wrapper now also takes care of skipping the UTF-8 BOM. Fix Ticket #3496.
2013-10-04	avformat/vobsub: fix several issues.	Clément Bœsch
	Here is an extract of fate-samples/sub/vobsub.idx, with an additional text at the end of each line to better identify each bitmap: timestamp: 00:04:55:445, filepos: 00001b000 Ace! timestamp: 00:05:00:049, filepos: 00001b800 Wake up, honey! timestamp: 00:05:02:018, filepos: 00001c800 I gotta go to work. timestamp: 00:05:02:035, filepos: 00001d000 <???> timestamp: 00:05:04:203, filepos: 00001d800 Look after Clayton, okay? timestamp: 00:05:05:947, filepos: 00001e800 I'll be back tonight. timestamp: 00:05:07:957, filepos: 00001f800 Bye! Love you. timestamp: 00:05:21:295, filepos: 000020800 Hey, Ace! What's up? timestamp: 00:05:23:356, filepos: 000021800 Hey, how's it going? timestamp: 00:05:24:640, filepos: 000022800 Remember what today is? The 3rd! timestamp: 00:05:27:193, filepos: 000023800 Look over there! timestamp: 00:05:28:369, filepos: 000024800 Where are they going? timestamp: 00:05:28:361, filepos: 000025000 <???> timestamp: 00:05:29:946, filepos: 000025800 Let's go see. timestamp: 00:05:31:230, filepos: 000026000 I can't, man. I got Clayton. Note the two "<???>": they are basically split subtitles (with the previous one), which the dvdsub decoder is now supposed to reconstruct with a previous commit. But also note that while the first chunk has increasing timestamps, timestamp: 00:05:02:018, filepos: 00001c800 timestamp: 00:05:02:035, filepos: 00001d000 ...it's not the case of the second one (and this is not an exception in the original file): timestamp: 00:05:28:369, filepos: 000024800 timestamp: 00:05:28:361, filepos: 000025000 For the dvdsub decoder, they need to be "filepos'ed" ordered, but the FFDemuxSubtitlesQueue is timestamps ordered, which is the reason of the introduction of a sub sort method in the context, to allow giving priority to the position, and then the timestamps. With that change, the dvdsub decoder get fed with ordered packets. Now the packet size estimation was also broken: the filepos differences in the vobsub index defines the full data read between two subtitles chunks, and it is necessary to take into account what is read by the mpegps_read_pes_header() function since the length returned by that function doesn't count the size of the data it reads. This is fixed with the introduction of total_read, and {old,new}_pos. By doing this change, we can drop the unreliable len16 heuristic and simplify the whole loop. Note that mpegps_read_pes_header() often read more than one PES packet (typically in one call it can read 0x1ba and 0x1be chunk along with the relevant 0x1bd packet), which triggers the "total_read + pkt_size > psize" check. This is an expected behaviour, which could be avoided by having a more chunked version of mpegps_read_pes_header(). The latest change is the extraction of each stream into its own subtitles queue. If we don't do this, the maximum size for a subtitle chunk is broken, and the previous changes can not work. Having each stream in a different queue requires some little adjustments in the seek code of the demuxer. This commit is only meaningful as a whole change and can not be easily split. The FATE test changes because it uses the vobsub demuxer.
2013-09-16	lavf/subtitles: Make comment less arrogant	Alexander Strasser
	Signed-off-by: Alexander Strasser <eclipse7@gmx.net>
2013-09-08	avformat/subtitles: support standalone CR (MacOS).	Clément Bœsch
	Recent .srt files with CR only were found in the wild.
2013-09-08	avformat/subtitles: add a next line jumper and use it.	Clément Bœsch
	This fixes a bunch of possible overread in avformat with the idiom p += strcspn(p, "\n") + 1 (strcspn() can focus on the trailing '\0' if no '\n' is found, so the +1 leads to an overread). Note on lavf/matroskaenc: no extra subtitles.o Makefile dependency is added because only the header is required for ff_subtitles_next_line(). Note on lavf/mpsubdec: code gets slightly complex to avoid an infinite loop in the probing since there is no more forced increment.
2012-12-31	lavf/subtitles: fix CLRF/CRLF typo.	Clément Bœsch

2012-12-31	lavf: move srtdec:read_chunk() to subtitles utils.	Clément Bœsch
	This function can be useful for various other subtitles formats.
2012-12-02	lavf/subtitles: add ff_subtitles_queue_seek().	Clément Bœsch
	This function is almost identical to lavf/assdec:read_seek2(). It performs a generic seek for text subtitles demuxers for the new seeking API. The only difference with assdec:read_seek2 is the ts_diff being unsigned to avoid overflows. The seek callback in the ASS demuxer will be removed when it is redesigned to use FFDemuxSubtitlesQueue.
2012-06-29	lavf/subtitles: add some SMIL helpers.	Clément Bœsch
	This is needed for SAMI and RealText demuxers.
2012-06-29	lavf: add internal demuxer helpers for subtitles.	Clément Bœsch
