For MIXED (partial SQL statements) and ROW mode are recorded in base-64 mode, the SQL section is displayed as base64 encoding, and two parameters need to be added to the normal display:

Mysqlbinlog-v-base64-output=DECODE-ROWS-start-datetime= "2017-08-14 16:30:29"-- stop-datetime= "2017-08-14 17:30:31"-- database=test mysql-bin.000893 > 1.sql
