@mochica This worked for me! I got the latest version of the linux zip, and replaced it with the command line using this:
sudo mv <new_file/file_location> <existing_file/file_location>
it was slow to load in the first video, but it looks like it's just because it's the first video it's loading with the new libffmpeg.so file (Also, because of the nature of the website that is loading in this class recording).
