That's weird. Are you sure the video is there and that it can be opened with your default video player? (e.g. VLC). If so, it sounds like OpenCV codecs issue maybe, could you check you can play videos with OpenCV and/or instead using the default OpenCV from apt-get?

Same issue. My specs are also same instead of: opencv : 3.4.0 GPU: RTX 5000

I had the same issue, but there was an OpenCV exception raised before it, quote:

_(-5:Bad argument) CAPIMAGES: can't find starting number (in the name of file): examples\media\video.avi in function 'cv::icvExtractPattern'

I solved it by copying the "opencv_videoio_ffmpeg450_64.dll" over to where the OpenPoseDemo.exe was built. As for "Why is that required if we use the opencv_world package?!", see PJ217's answer to a seemingly similar issue on stackoverflow:
