Hi:
I'm running example mentioned here https://software.intel.com/en-us/articles/how-to-create-video-wall-with-...
I got the following output but no rendering on monitor.
My understanding is that vpp_comp_only 4 ensures that it displays on monitor.
Aung.

Some inter-sessions do not use opaque memory (possibly because of -o::raw).
Opaque memory in all inter-sessions is disabled.
