is added in the VQE Configuration tool.
High Efficiency Video Coding (HEVC) Support
In Cisco CDA VQE 3.10 Release,, VQE-S is enhanced to support RCC for H.265 encoded High
Efficiency Video Coding (HEVC) channels.This enhancement is license based service and the service
providers must procure a license from Cisco and install in /etc/opt/vqes directory in the server so that
VQE-S supports caching of HEVC channels and RCC is enabled on HEVC channels. If there is no
license in the system, the RCC enabled H.265 encoded channels becomes inactive at the 6 minute mark
and errors are logged in /var/log/vqe/vqes.log
