ffmpeg no longer working #19

Hi, thanks for the code! Works well to extract motion vectors. However, after installing this, the standard ffmpeg no longer works for me. For instance the command: ffmpeg -start_number 1 -i %04d.png -r 25 output.mp4 which worked without issue before, now gives:

I am using Ubuntu 20.04. What is going wrong?

I didn't encounter such an issue at my end so I am afraid, I can't help. Seems the default ffmpeg lib path is now pointing to /opt/. Can you try removing everything and installing ffmpeg first and then MV-Tractus? Try to change the installation path of ffmpeg to the default one instead of /opt/. /opt/* was only used for test purposes.
