VC-2 is a royalty free, ultra low-latency, ultra high quality video codec designed for use in broadcast environments. The provides comprehensive testing routines for implementations of the VC-2 codec to ensure that they conform to the published specification (). As well as verifying correct operation, conformance testing of codec implementatons helps ensure interoperability between codec implementations.
You can read more about how the VC-2 Conformance Testing Software works and some of the tricks it uses to ensure it itself conforms to the VC-2 specification in the post 'VC-2 Video Coding: Getting it right' on the 成人快手 R&D blog.
If you're developing a VC-2 codec you can find the complete conformance testing procedures in the (also availble in ).
