Need test case for MIAF 7.3.11.4.1 #2

Closed aklemets closed 3 years ago

aklemets commented 4 years ago

I could not find a test case for MIAF paragraph 7.3.11.4.1:

All input images of a grid image item shall use the same coding format, chroma sampling format, and the same decoder configuration

All input items to a grid shall have the same explicit or default colour information

The input images of a grid image item shall be encoded such that each can be independently decoded

This one is indeed not yet done because nclx is not present it is non-trivial to compare chroma format. This was discussed at the MPEG meeting of Oct 2019.

I've just implemented it.
