I've configured transcoder with Quick Sync enabled on my PC. CPU is i5-4670 with 4600 graphics, it has the capability. However, main GPU in this PC is NVidia GTX 660. Intel 4600 driver is installed too.
When I restart Wowza server (it was configured as a Windows service) I see in %install-dir%\logs\wowzastreamingengine_error.log the errors "Intel Quick Sync accelerated encoding is not available when running as a service on Windows". Well, fine at least it tries to start. Then I shut it down and start it in standalone mode with %install-dir%\bin\startup.bat. It starts, no errors in log, but the CPU load is about 35-50%. When doing software transcoding it also was about 35-50% of CPU load, so it seems like no hardware acceleration is applied.
Any way to check if it really transcodes as Quick Sync? Do I have to use Intel 4600 as the main GPU for it to be able to "Quick Sync" the transcoder?
