Can't train or infer in macos // issue with ffmpeg

[Cptn-Reynolds]

I saw there is a macos version of the gui and got it running.

I was able to "train index" one time and "train", but when trying to use "Inference" afterwards, it crashed with an ffmpeg error.

Error while train indexing

To use this software, ffmpeg must be installed on your PC.
If you are using MacOS, you can install ffmpeg using homebrew.

[Cptn-Reynolds]

According to the Requirements.txt, the ffmpeg-python package is installed in the python environment when running webui.sh - shouldn't this be enough?

[ddPn08]

I recognize that ffmpeg-python is a library for operating ffmpeg installed on os.
So you need ffmpeg installed.

[Cptn-Reynolds]

I see, thanks for clarifying :) Will update you after testing

[noisyneil]

Could you possibly provide a link to the instructions for macOS installation? It's all a bit bewildering.
