Comment (by jamal):

 "ChapterUID: 0"
 That seems to the problem. The Matroska demuxer is ignoring the chapter
 with uid 0, and reading the second one (With uid 1) as if it were the
 first.

 The ffmetadata demuxer assigns the id 0 to the first chapter it reads from
 src_meta.txt, and the Matroska muxer used it.

 mkvalidator doesn't complain about the resulting file tgt_video.mkv, so 0
 is a valid value for ChapterUID.
