avformat/vobsub: do not attempt to check duplicate subtitles Some .idx files actually contain duplicate subtitle events: timestamp: 00:07:52:600, filepos: 00004e800 timestamp: 00:07:52:600, filepos: 00004f800 The second will be dropped, because it has same pts, duration, and text (the text is just a dummy empty string; the real data is retrieved when actually reading vobsub subtitle packets). Dropping this is probably not intended/safe, so avoid it. See trac issue #4872 for a sample. This patch doesn't fix decoding of the sample, though. > http://git.videolan.org/gitweb.cgi/ffmpeg.git/?a=commit;h=5c93e57f5c07b52f04363c178c4fc1892c0d71aa --- libavformat/mpeg.c | 1 + 1 file changed, 1 insertion(+) diff --git a/libavformat/mpeg.c b/libavformat/mpeg.c index a63b567..55f2b3f 100644 --- a/libavformat/mpeg.c +++ b/libavformat/mpeg.c @@ -857,6 +857,7 @@ static int vobsub_read_header(AVFormatContext *s) for (i = 0; i < s->nb_streams; i++) { vobsub->q[i].sort = SUB_SORT_POS_TS; + vobsub->q[i].keep_duplicates = 1; ff_subtitles_queue_finalize(s, &vobsub->q[i]); } _______________________________________________ ffmpeg-cvslog mailing list ffmpeg-cvslog@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-cvslog
