JPEG2000 Decomposition Levels

For 4K contents.
Mixing essences with different decomposition levels won't work when playing on a 2K system.

E.G.

Reel 1
-- JPEG 2000 Metadata --
ImageComponents:
bits h-sep v-sep
12 1 1
12 1 1
12 1 1
Scod: 1
ProgressionOrder: 4
NumberOfLayers: 1
MultiCompTransform: 1
DecompositionLevels: 6
CodeblockWidth: 3
CodeblockHeight: 3
CodeblockStyle: 0
Transformation: 0
Precincts: 7
precinct dimensions:
1: 128 x 128
2: 256 x 256
3: 256 x 256
4: 256 x 256
5: 256 x 256
6: 256 x 256
7: 256 x 256

Reel 2
-- JPEG 2000 Metadata --
ImageComponents:
bits h-sep v-sep
12 1 1
12 1 1
12 1 1
Scod: 1

5: 256 x 256
6: 256 x 256

It seems that it is reproduced on any system.

Good one, thanks

The error appears in case of version files (if a "referenced asset file not listed in Assetmap dictionary").
It should not.

[AndreiGravelle]

I have noticed that running dcp inspect with the --as asset store command in the case of version files avoids getting this error. Empirically, it is a false error as if instead of reading the VF as incomplete, it reports an error on picture. Once the VF is linked to the OV, the error disappears.

PR #84 prevents these errors on VF DCPs where the relevant asset is not present in the ASSETMAP.

@overlookmotel thanks, see #93 (comment)

Both issues - wrong error for VF/Supplemental wrt picture decomposition levels and sound channel format - should be fixed with 1356204 and 67d0d38

Can you confirm?
