[Bug] Very High CPU Usage when encoding into AV1 and H265 with Intel QSV in Unraid with Arc A310

[ampersandru]

Current Behavior

When encoding into H265 or AV1 using Intel QSV, there is very high CPU usage while still using GPU acceleration

Expected Behavior

There should be minimal CPU usage while using GPU encoding. Using Tdarr to encode into h265 does not skyrocket CPU usage at all

Steps To Reproduce

Encode any video file using Intel QSV

Environment

• OS: Unraid
• OS version: 6.12.10 with custom kernel: https://github.com/thor2002ro/unraid_kernel/releases
• CPU: Intel Core i5-1235U
• GPU: Intel Arc A310
• Docker version: 1.7.3
• Device model: Ugreen DXP6800 Pro
• Browser/OS: Chrome

Container creation

Installed directly from the Unraid app store, which installed the docker container. I did add the device "/dev/dri" as a variable
