           Summary: apply the rsync comparison algorithm specially to .mov
                    and .mp4 files
           Product: rsync
           Version: 3.0.2
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P3
         Component: core
        AssignedTo: wayned at samba.org
        ReportedBy: Dave at Yost.com
         QAContact: rsync-qa at samba.org


These files are huge, and being able to drastically cut back on retransmission
for such files would be a really big win. Many changes to these files involve
changes to a tiny part of the file that changes in size and thus shifts the
giant media data portions to a new offset not on a block boundary.

When rsync encounters one of these files, it should checksum each atom of the
file instead of each block.
