wm4 6b1374b203 sd_ass: change license to LGPL ... All contributors of the code used for sd_ass.c agreed to the LGPL relicensing. Some code has a very chaotic history, due to MPlayer subtitle handling being awful, chaotic, and having been refactored a dozen of times. Most of the subtitle code was actually rewritten from scratch (a few times), and the initial sd_ass.c was pretty tiny. So we should be fine, but it's still a good idea to look at this closely. Potentially problematic cases of old code leaking into sd_ass.c are mentioned below. Some code originates from demux_mkv. Most of this was added by eugeni, and later moved into mplayer.c or mpcommon.c. The old demux_mkv ASS/SSA subtitle code is somewhat dangerous from a legal perspective, because it involves 2 patches by a certain Tristan/z80, who disagreed with LGPL, and who told us to "rewrite" parts we need. These patches were for converting the ASS packet data to the old MPlayer text subtitle data structures. None of that survived in the current code base. Moving the subtitle handling out of demux_mkv happened in the following commits: bdb6a07d2a, de73d4dd97, 61e4a80191. The code by z80 was removed in b44202b69f. At this time, the z80 code was located in mplayer.c and subreader.c. The code was fully removed, being unnecessary due to the entire old subtitle rendering code being removed. This adds a ass_to_plaintext(), function, which replaces the old ASS tag stripping code in sub_add_text(), which was based on the z80 code. The new function was intended to strip ASS tags in a correct way, instead of somehow dealing with other subtitle types (like HTML-style SRT tags), so it was written from scratch. Another potential issue is the --sub-fix-timing option is based on -overlapsub added in d459e64463. But the implementation is new, and no code from that commit is used in sd_ass.c. The new implementation started out in 64b1374a44. (The following commit, bd45eb468c removes the original code that was replaced.) The code was later moved into sd_ass.c. The --sub-fps option has a similar history.		2017-04-20 12:53:24 +02:00
