could there still be an issue:
I manually copied nvEncodeAPI.h into /usr/include/x86_64-linux-gnu
Is there a procedure to install nvenc correctly?

[mean]

It's trying to load :
libnvidia-encode.so.1
libcuda.so"

make sure you have them

[Jan Gruuthuse]

libcuda.so:
libnvidia-encode.so.1:
both are there:

found in /usr/local/cuda/samples/bin/x86_64/linux/release these tools: deviceQuery and deviceQueryDrv (in device.zip attached)

I dont think your video card supports nvenc
I had a 610GT which is similar and it was not supported

[Jan Gruuthuse]

That would explain this.
So we are back @ minimum requirement would be an nvidia GPU GM10x or GM20x

Had to do some HW upgrades, replaced
- GT520 by GTX960 (required PCIe 3.0)
- motherboard MS-7680 (H67 chipset PCIe 2.0) by Z77 extrem3 (Z77 chipset PCIe 3.0)
switching to LGA 2011ââ,¬â€˜3 was too expensive, for now.
