I eventually did get 'python3 -m build' to work by installing scenedetect and upgrading numpy. Perhaps consider requiring minimum versions for the dependencies to avoid strange behavior. The result was a tgz file identical to the one I downloaded, so I concluded "build" was probably not what I should be running to install.
I attempted to run the program in place, but ran into a claimed circular dependency. I have the latest versions of numpy and scenedetect as shown from pip:

Thanks for bringing this to my attention, fixed that up.

When I view https://dvr-scan.readthedocs.io/en/latest/guide/installing/ I am still seeing "404 Page Not Found" in the bottom third of the page. I opened it with an incognito window to ensure there isn't any odd caching or cookie thing going on.
Similarly, on https://dvr-scan.readthedocs.io/en/latest/download/ there is a link "Installing & Updating" that points to https://dvr-scan.readthedocs.io/en/latest/download/guide/installing.md that when followed appears to be the same page as noted above, with the 404 message on it.

Looking at the source files for the docs, it appears the installing.md file has been removed. There are multiple links pointing to this file still in the docs.
I have been on 1.4 and it appears things have changed significantly and upgrading is non-trivial on a linux system. The download.md file implies that upgrading consists of extracting, running "python -m build" and then installing with pip. I assume the same instructions for a pip install documented at the top of that page apply.
The installing.md file that was removed documented the dependencies, IIRC. If that information has moved to another file, I cannot find it.

I could not get the build to work as stated. I also tried "dvr_scan" and that ran but failed, perhaps because of a missing dependency? My python knowledge is very limited but I wanted to try to get through this today, so I am hacking.
I realize this information probably does not belong in this issue, but I am hoping my problems are related to not being able to reference that removed doc file.
Here is the output from my commands for reference:
sg@G7:~/dvrscan/extract_151/dvr-scan-1.5.1$ python3 -m build

Thanks for providing that output - this issue was raised in Breakthrough/PySceneDetect#350 but I haven't had a chance to look into it yet. I assume the issue might be importing ndarray from numpy rather than just importing numpy itself. Feel free to post any follow-ups on Breakthrough/PySceneDetect#350, and thanks for the output again.
