This release focuses on significant CPU savings by using hardware acceleration (VAAPI) to offload the live view display from the CPU to GPU.  Currently this is best supported in Linux, however other changes in this client release will have lower CPU on all platforms.  Current tests of this client version compared to previous versions show a 60% CPU usage drop on 8 live view HD streams.

This releases also resolves several reported crashes (see release notes below).

As always you can download the client on our website, or run ‘sudo apt-get update ; sudo apt-get install bluecherry-client’ on Ubuntu / Debian systems.  Optionally you can build the latest client yourself by downloading the source code here (

Any issues can be reported to the community forums
