The signer works with video segments instead of video frames; the duration of the segments must be configurable.
The signature spans over the hash of all video data packets and the hash of the previous segment. It should also include the content UUID, the hash method, and start and end flags are included in the signature, so that this data cannot be modified. (See IBC2025PaperAuthentication_HHI.pdf and probably the spec to understand how it's done)
The Signature meta must include all the necessary information to generate the DSCI SEI message (hash method, public key, etc...)
The verifier should not need the public key information; the public key is part of the DSCI SEI message, and it should be available in the meta.

… frame. Use GOP-1 signing approach Hash both previous digest and current one

Compose the public key uri based on key-storate-path in verifier and cert_uri metadata
