Changeset 951 in SHVCSoftware for branches/SHM-dev/source/App/TAppEncoder

Timestamp:

Message:

Some fixes for implementation of support for profile tier and level for each layer in an output layer set.
Additionally, add conformance checking such that enhancement layers of an output layer set support the same profile.
