How to regenerate the manifest store files

To generate the manifest store files:

1. Install C2PA Tool locally and ensure it’s on your path.
2. Clone this repo locally.
3. Run the extract-manifests.sh script as follows:

   cd public-testfiles
   ./extract-manifests.sh
   

The script runs C2PA Tool on all the files in the video/mp4, image/jpeg, and pdf directories with the -d option to generate a detailed and standard manifest reports, saving them to sub-directories with the same base name as each asset within the manifests directory. Each sub-directory will also include extracted thumbnails.

NOTE: The PDF file does not have any Content Credentials, so it is not included currently.
