Description
There seems to be a mismatch between the spec and VTM software regarding colour space conversion.
In spec, equation (1226), rCr[ x ][ y ] is calculated as:
rCr[ x ][ y ] += rCr[ x ][ y ]
while in VTM it is calculated as:
rCr[ x ][ y ] += rCb[ x ][ y ]
From the original proposal JVET-Q0510 and what was adopted in the meeting, the spec should be corrected (software is correct). There is a mistake in the combined spec JVET-Q0820.
