Stream Deployment File Format
The CAM Stream Deployment (CSD) data is mostly a serialized version of the Stream Configuration File Format which is easier to be consumed by cam-service.
Files should use the extension .csd.
All multi-byte types are little-endian.
- About the Universally Unique Identifier (UUID) fields:
UUIDs are 16-byte long fields representing the 128-bit UUID in binary format
- The file format does not enforce any UUID variant. UUIDs are used as anopaque data value and does not process the sub-fields of the UUID.
