I have exactly the same problem, any workarounds?

@FrancoCorleone You could manually edit gif_for_cli/generate/__init__.py to add my fixes Add missing "rows" option in _save_config and Add fallback regex method to _run_ffmpeg. If you are on arch, the files should be in ~/.local/lib/python3.11/site-packages/gif_for_cli-1.1.2-py3.11.egg/. If not, check the path in your error message.

Edit: If you don't feel like manually editing, you could also replace gif_for_cli/generate/__init__.py with the one from my repo.

Same issue here.

I tried replacing gif_for_cli/generate/init.py with the one from your repo, but it doesn't work for me.

@Cephir23 That may be because you have already used the bugged version of gif-for-cli. When gif-for-cli reads a GIF, it creates a cache directory for the image where it places a config.json, which contains num_frames. Once that config is created, it will remain the same on each execution, so num_frames should still be 0, causing a divide by zero error. On my system (probably yours as well since you use Arch), the cache directory is ~/.cache/gif-for-cli/1.1.2. If there are any directories in the cache, try removing them and rerunning gif-for-cli.

Worked! Thank you so much.

num_fames is on: gif_for_cli/generate/init.py

just replace it

• num_frames = int(re.search(r'frame=\s*(\d+)', err).group(1))

• num_frames = len(glob.glob1('{}/'.format(output_dirnames['jpg']),"*.jpg"))
