Invalid Level 9 metadata from XML #104

Closed quietvoid closed 2 years ago

quietvoid commented 2 years ago

Apparently writing a level 9 block with only source_primary_index: 255 is invalid. There might be the actual primaries expected in the RPU.

When we write an RPU containing a level 9 block with 255 primaries index, the Dolby verifier panics.

I managed to figure out the predefined list of primaries for L9 and L10, and L9 have a longer list. The SourceColorModel field in XML is unrelated to RPU data, should always be 255, and primary_index: 255 means custom color primaries is present in RPU.
