Day #102 - Error - Opening Video File using OpenCV python

Sometimes the setup settings, I actually forgot.

Error - RuntimeError: invalid rotation plane specified

Actual Setup  - Copy your opencv_ffmpeg.dll to C:\Python27\ and rename it to relevant your OpenCV Python Version. In my case, I had to rename it to opencv_ffmpeg240.dll

In my case opencv version was 3.4.1

Often, These setup steps are missed once things start working. This link was useful - link
