Thank you for the log for vainfo and qsvencc.

May I have information about the CPU(iGPU) you are running on, as it shows "Ivybridge" in the vainfo log.

vainfo: Driver version: Intel i965 driver for Intel(R) Ivybridge Desktop - 2.4.1

Unfortunately, QSVEnc requires Broadwell CPU or later to work on Linux systems.
