Running into issues during build time with ffmpeg and ffprobe. Always get an error saying ffprobe was not found. Any solution to this? I’m basically using gatsby-transformer-ffmpeg and gatsby-plugin-ffmpeg

Hi @hideodaikoku, I moved your post to its own topic since it’s not related to Netlify Lambda Functions.

That said, for any binary executable files like ffmpeg or ffprobe that’s not included in the [build-image](https://github.com/netlify/build-image/blob/xenial/Dockerfile) we use, you’ll need to provide that yourself, by either including the binary in your repository or some other way. It’ll be up to you.

Hopefully that helps point you in the right direction.
