ksuehring/VVCSoftware_VTM:idr_nlp into master
Merged Karsten Suehring requested to merge ksuehring/VVCSoftware_VTM:idr_nlp into master

In case there is no reordering in the GOP, leading pictures cannot occur withing the VTM encoding process (e.g. LDB/P configurations).

    Should the description of the MR be different? The code checks for the presence of reordered pictures which isn't the same as not having leading pictures.

    You are right. What is tested is a more strict GOP constraint that leads to no leading pictures being present. I updated the description and the commit comment.
