(not gonna include mycerts.pem or mykey.pem 😌)

Running sidecar-cmd.sh on c2patool 0.7.0 generates photographs-of-snowmen-13-signed.c2pa, and copies photographs-of-snowmen-13-optimized.jpg to photographs-of-snowmen-13-signed.jpg unmodified, as expected.

Running these same commands on these same files using the latest version of c2patool (0.10.2) puts the following on stdout:

claim generator [ClaimGeneratorInfo { name: "c2patool", version: Some("0.10.2"), icon: None, other: {} }]
Error: No claim found

And does not generate a sidecar .c2pa file. Additionally, it ouputs a file to disc named xmp/iid/191d9470-cf46-4511-b4f9-820f9ce7ea4b which is a JPEG, that mysteriously weighs 32KB more than the input JPEG.

Seems related to #831

I get a slightly different error:

$c2patool sample/image.jpg -m sample/test.json -p sample/C.jpg -o signed_image.jpg --sidecar
claim generator [ClaimGeneratorInfo { name: "c2patool", version: Some("0.10.2"), icon: None, other: {} }]
Error: embedding manifest

I can confirm, same for mp4-files.

last working version was 0.9.6.

Does not work either in version 0.11.1

➜  sample git:(main) ✗ ./c2patool_0111 image.jpg -s -m test.json -o image_signed.jpg
claim generator [ClaimGeneratorInfo { name: "c2patool", version: Some("0.11.1"), icon: None, other: {} }]
Error: embedding manifest

or with mp4-file

➜  sample git:(main) ✗ ./c2patool_0111 input.mp4 -s -m test.json -o output.mp4 
claim generator [ClaimGeneratorInfo { name: "c2patool", version: Some("0.11.1"), icon: None, other: {} }]
