For example the old recording file before windows reinstall those file are not in the new database ,so I we rebuild the data base ,but when rebuild database
the live view also recording In the same time , the system or hdd is overload ,this part we have feedback to our RD team.
After the old recording files are format by cycle recording the new recording file and data base are complete (doesn’t need any rebuilding)
If you see the old playback is not complete you also can use recordstream player to check the playback
