The process cannot access the file because it is being used by another process

[PatoFlamejanteTV]

Hi, I recently tried to use this tool, but all I get is this error: "The process cannot access the file because it is being used by another process". I had used it more than once before, and it had worked, but for some reason, it is no longer working.

Same issue, but now, all the files are in the same folder:

That's new, never seen that before I believe.

Idea 1: Perhaps some kind of antivirus is looking at temporary folders? In the Resource Monitor under Disk, you can see what programs are using what file.

Idea 2: This is a long shot, but it sounds like you've ran out of space trying to use stammer; stammer extracts all frames of the video to disk by default. If you have the RAM to spare, try using stammer in mem_decay mode with -vm mem_decay -mcf 5. That will make stammer read the video on-demand as frames are needed and will only use your disk space for audio, which is not too big.

Also, tell me your Python version python --version.

I accidentally ended up "fixing" this, probably the video was too big and caused this problem, for some reason only that video was causing this problem.

My current python version is: 3.12.5

I was not using an Antivirus, i was just using Windows Defender, NextDNS, UBOrigin, but NextDNS is just an DNS-over-HTTP thing and just "filters" HTTP requests, and UBO is just for browsers.

Yeah. I recommend you use mem_decay when the carrier is high-quality/very long
