1Why the files in this directory are considered invalid: 2 3block_ends_beyond_cluster.mkv - 4 File containing a single cluster with two simple blocks. One valid, and the 5 second reporting a size that would cause the block to end far beyond the end 6 of its parent cluster. 7 8blockgroup_block_ends_beyond_blockgroup.mkv - 9 File containing a single cluster and two blockgroups. The first blockgroup is 10 valid. The second blockgroup contains a block reporting a size that spans well 11 past the block and the end of the file. 12 13chapters_truncated_chapter_string.mkv - 14 File with a Chapters element that ends with a ChapterAtom whose ChapterDisplay 15 element contains a truncated ChapterString. 16 17chapters_truncated_chapter_string_2.mkv - 18 Nearly identical to chapters_truncated_chapter_string.mkv, but with a void 19 element and a partial cluster. Causes mkvparser to fail in a slightly 20 different manner. 21 22fixed_lacing_bad_lace_size.mkv - 23 File containing a BlockGroup with fixed lacing, but reports a total laced size 24 that is not evenly divisible by the number of laced frames. 25
