The building construction took longer than expected so I could not attempt the extraction process with the customised script until yesterday. And a big success it was!! Extracted a little over 46000 images from the memory card in no-time. Thanks again for your effort Alex. Much appreciated...

Alex, I finally managed to find an identical micro-SD-card (128GB) as in use at the construction site and ran a series op captures on the same type/mod camera. The close to 4000 images were extracted in minutes and are perfectly readable. And by placing the output folder outside of the input...

DS-2CD5A46G0-IZS. It's a 4MP Bullet camera from the Darkfighter range. Not sure which year of manufacture as I got them as used but I believe these were produced since late 2019 until mid 2021.

Relocated the jpg directory outside of D:\Hikv and removed all subdirs except for datadir0. That indeed did the trick and the error message is now gone. In the next week I will try to find an identical SD-card as I have used in the camera at the construction site. Then I will have an "identical"...

The other camera is the same model and has the same firmware level as the one that I used for testing. The only difference is the size of the SD-card. So hopeful The source data is in D:\Hikv\datadir0 The output is in D:\Hikv\jpg Is that ok or should the jpg dir be somewhere else? Again: This...

Alex, you continue to amaze me! Your response is crisp and you provide adjusted coding with lightning speed. Impressive. I ran the updated code against the three test-sets that I created earlier. For this I used two different SD-cards which were formatted in the camera before use. The three...

Alex, thanks for all the effort you are putting in! Tried the new script against the existing test-set which contains the index file I sent. It starts working on the first .pic (xxx00000) and unpacks the jpg's successfully. After processing all files (incl the empty ones) the script displays...

Gave it a quick try on the smaller test bundle and the Python script pulls the jpg's just fine! (24 captures) Will try the same on a larger bundle tomorrow and will report the results. Promising!!

Thanks! Attached is the requested file... Will try to work the Python script tomorrow.

Did some testing. Running the script on the test-set with the 0KB .pic files deleted first. The only remaining .pic file is hiv00000.pic : same 10 min ...processing datadir0... ended with an error saying: Can't find hiv00001.pic in the input folder. So my assumption is that the script knows...

I formatted the memory card and then only ran the camera for 15 mins or so. Could it be that all captures are in the first file (xx0000.pic) and that the following files are just empty? I could do another test and run the capturing for a couple of hours or a whole day, if you want.

Extra info.... Found and tried Ext2fsd on my Win10 laptop with the SD-card inserted. Could read the files with identical results: 0KB .pic files and a time stamp 2 hrs ahead of the actual time. I checked the time setting of the camera and that seems to be correct and in line with my Windows...

Ok, so I formatted a new SD card and set up the camera to capture an image every minute. I was able to download the images directly from the camera as viewable jpg files. I then took out the card from the camera and connected it to my Synology (since Windows does not recognize EXT4 formatted...

Thanks Alex, in my first attempt, I put all the datafiles in the datadir0 folder and kept the other existing folders intact. That resulted in an error from the script, saying: Can't find event_db_index01 or index00p.bin or index01p.bin in D:\Hikv/datadir0/lost+found . So I deleted the other...

Hi Alex, Thanks for looking into this. Much appreciated! Screenshots are attached. Please note that the number of .pic files runs all the way up (didn't include all screenshots of those).

Hello, Thanks much for your effort in creating a process for mass extraction of JPG's. I am setting up a timelaps (1 image per 5 minutes for approx 1 year) so this might be a great help!! I've been trying the software on a test-set of data. Successfully loaded the data from the memory card to...
