How to get the raw video files of Didemo through `/storage/vis_db/didemo`

Hi! Thank you for your nice work! I'm trying to download the required datasets through your scripts. And I get `data.mdb` and `lock.mdb` in the folder `/storage/vis_db/didemo` after running the dataset downloading script. How to get the raw video of the dataset through the files `data.mdb` and `lock.mdb` now I get? Thank you very much!
