@blank-ed , thanks for raising the issue. For me, accessing a recorded video works without problems. How are you passing the filename to yarppg? I do get the same error,...

Apparently, there is no clear cut way to limit the FPS through OpenCV directly. I found several related questions on Stackoverflow (like [this one](https://stackoverflow.com/questions/45853671/read-video-file-with-fixed-frame-rate)), but no official documentation. A quick...

many thanks for the detailed elaboration. I agree that an optional FPS limit would be a good thing. And yes, sleeping the entire delay is not great - doing it...

I have started working on this in a new branch. Yes I am seeing the same problem, with FPS being lower than intended. For me, it looks like there is...

@blank-ed > Additionally, yarppg is incredible, thank you! I understood RPPG much better and faster from reading and understanding your code compared to reading different papers since your code shows...

thank you for reporting this. I see no issues with 3.11 on windows, but on Ubuntu through WSL i get the same issue. For me, however, installing opencv-python-headless does not...

This looks a lot like the MacOS-specific problem not related to yarPPG. Can you try this solve here: https://stackoverflow.com/a/58525755/10694594 Please let me know if it works afterwards.

You can run the programm with `run-yarppg --savepath=./signals.csv` which will write a history of the recorded processor values after the window is closed. Concerning HRV, you may need to consider...

It depends on the algorithm/processor you choose. By default, you get a bandpass-filtered version of the average green channel in the region of interest. For HRV, you would need to...

I actually just this week updated the repo with a complete rework of the functionality. There is now also a documentation for most of the code. You can go through...
