[Win10 64bit] OpenCV exception: CAP_IMAGES: can't find starting number

[notune]

When trying to embed a file under windows (compiled using rust's cargo), I get the following error (even tho the program states that it embedded the video successfully, no output.avi appears in the directory):

...
Etching frame ended in 110ms
Embedding thread complete!
[ERROR:0@167.784] global c:\build\master_winpack-build-win64-vc15\opencv\modules\videoio\src\cap.cpp (597) cv::VideoWriter::open VIDEOIO(CV_IMAGES): raised OpenCV exception:

Video embedded successfully at output.avi

I think this might have something to do with the paths being different under windows, according to this stackoverflow-answer, but I might be wrong
