The current secure camera implementation suffers with a few issues in terms of typecasting, error handling and in populating the information in the right data structures when the new SCM API is used on the targets without domain ID support. In addition, we needed to be explicit in failing to acquire if dual IFE is required in secure camera use cases as it is not a supported feature as of now.
