Can't get the hardware acceleration (VAAPI) working on TS 677 with PCIe GPU Nvidia GTX 1050 Ti: Failed to initialise VAAPI connection

[chrisjace]

I have followed the instructions, but can't get the hardware acceleration working.
Below is my environment:
QNAP TS 677, with external PCIe GPU Nvidia GTX 1050 Ti
Hardware acceleration working fine with Plex

QTS firmware version: 5.0.1.2376
NVidia GPU driver package installed: NVIDIA_GPU_DRV_5.1.0.0822_x86_64.qpkg
VA-API device showing as: /dev/dri/renderD128

I have tried different combinations of QNAP.Configuration Plugin VAAPI driver with: DefaultValue, i965, and iHD. All failing.

Error I am getting in the logs:
[AVHWDeviceContext @ 0x5555563ce4c0] Failed to initialise VAAPI connection: -1 (unknown libva error).
Device creation failed: -5.
Failed to set value 'vaapi=va:/dev/dri/renderD128' for option 'init_hw_device': Input/output error
Error parsing global options: Input/output error

Any help, whatelse I should be looking at, would be much appreciated!

Thanks!
JC

I managed to solve the issue by adding the /opt/NVIDIA_GPU_DRV/usr/lib to LD_LIBRARY_PATH. I now have the hardware acceleration with Nvidia NVENC and my external PCIe GPU working! The following post was really helpful: https://forum.qnap.com/viewtopic.php?t=167052.
