Doesn't seem to work... Errors out: invalid syntax, line 17 #5

It would definitely help if you included the command syntax so maybe the problem is that I had to guess...maybe it is a dependency issue?

I found, and used, this script today (thank-you kindly, @harryjackson, this works beautifully!)

It errored for me when I used a command line similar to yours, @iconoclasthero.

When I ran it with python 2 and the -f command line option, all good. I also had minor dramas with the dir it wrote output to. prefix the filename with a path helped. (ubuntu 20.04, python 2.7.18)

bad examples:

python3 split_ffmpeg.py myfile.mp4 - nope (errors) python2 split_ffmpeg.py myfile.mp4 - nope (errors similar to yours, I think, didn't make a note) python2 split_ffmpeg.py -f myfile.mp4 - nope - write error, can't access /myfile dir

working example:

python2 split_ffmpeg.py -f ./myfile.mp4 - yes - works nicely

I also tweaked lines 87-92 to change the ffmpeg command line to add some encoding, but I think that's unrelated to issues you're having / I had.

for interest, my workflow:

  1. rip dvd using old faithful 'dvd decrypter' (on windows)
  2. convert/encode (as pass-through as possible) to m4v using handbrake with chapters -> create chapter markers enabled (windows)
  3. use this script - split_ffmpeg.py - to split the m4v files to individual chapters (on linux, my go to wherever possible, I didn't try this script on windows but it'll probably work fine if dependencies are all OK)

hth,
