The method of prompting a local ffmpeg installation does not seem to work on macs (OS 13.6). With an independent installation of ffmpeg, there are issues with calling video files to show via ffplay. Errors without mode='notebook' in video.show(): No such file or directory: ffplay fileloc.mp4 -window_title fileloc.mp4 -x 640 -y 480
Additionally, fails to read file locations without explicit paths, for example ../file.mp4

Fortunately, specifying path explicitly and using mode='notebook' seems to allow videos to be called and displayed. So far other functions are behaving as expected.

One potential source of conflict are structures of ffmpeg commands for OS running commands in ZSH instead of BASH.
