NVenc: --weightp is not compatible with the new Nvidia driver (387.92)?

[ms4r75]

I've updated the Nvidia driver with the last 387.92 and StaxRip stopped working with my encoder setup. After some tests, step by step, I found out that the switch "--weightp" is the reason. I tried with StaxRip 1.7.0 stable and 1.7.0.2 test build. My configuration: Intel Core I7 4770k with NVidia GTX1080 Windows 10 Pro 64bit

P.S. I tried H265 encoding only

Regards

[rigaya]

Thank you for your report.

I've been testing --weightp with 387.92 driver, but seems to have no problem.

Would you mind showing me the exact command line that Staxrip has generated?

Can you try also with H265?

this is my line: --vbrhq 3500 --codec h265 --preset quality --level 4.1 --output-depth 10 --weightp --lookahead 32 --aq --vpp-edgelevel --vpp-deband

If i try without '--weightp', everything works fine.

[rigaya]

Thanks, I was able to reproduce the issue.

I'll check whether this could be avoided by the app, or it is some kind of driver issue and we should wait for driver update.

[ms4r75]

Great! Thank you

I have the same issue. I'm actually able to encode some clips but on many I have the exact same crash while --weightp is enabled. Can't paste the crash log now but I'm on newest build of Win10 x64, encoding on GTX 1060, with staxRip 1.7 and 1.7.0.4.

[rigaya]

I'm currently not able to fix this issue, will probably have to disable weightp on HEVC encoding.

[ms4r75]

so is it lost forever?

[pberenyi]

Hi,

just as an info, 388.31 and GTX 1050 has the same issue with the weightp option.

I was not able to find out what is going wrong with weightp, so unfortunately I decided to disable it on HEVC encoding. (NVEncC 3.25)

You can override this behavior and still use weightp by using "--weightp force", but this is only for testing, and not recommended.

Thank you everyone for sharing the problem, I will merge this issue to #34 , and close this issue.
