Comment (by BugMaster):

 This file is out of spec 4:4:4 x264 encode with x264 SEI removed (may be
 due splitting of mkv). It can't be decoded without x264 SEI. To fix it you
 need to either restore x264 SEI (with core 150 or lower) or re-encode it
 with new x264 version (r2851 core 151 or higher) where out of spec
 behavior was fixed (or with old version but 8x8dct disabled).
