Owner: changed from Antoine Martin to Andrei K

Can you please run it again with loader.py -v, or with XPRA_NVENC_DEBUG=1 loader.py?

I think that the P1000 requires license keys for opening more than 2 sessions, but it should work OK without.

What OS is this on? And what xpra version?

comment:3 Changed 6 months ago by Andrei K

nvidia-smi encodersessions concurrently shows zero sessions.

Debian 5.2.17-1rodete3 and xpra v3.0.8-r25881 (built from source)

Cool, so you can try with r26133 applied.
And then please run with:

XPRA_NVENC_DEBUG_API=1 XPRA_NVENC_DEBUG=1 loader.py

This should tell us the exact error causing nvEncOpenEncodeSessionEx to fail.

I noticed Cuda version 8 in logs, while I have installed 10. Not sure if it's the same version meaning.

CUDA 8.0.0 / PyCUDA 2019.1.2, found 1 device:

That's the CUDA version that was used for building pycuda.

From that log output, you haven't applied the patch yet, right?

TransientCodecException: cannot open encoding session: 15: This indicates that an invalid struct version was used by the client

Because your driver is not the latest, you may want to rebuild against an older SDK version to see if that helps.

comment:11 Changed 6 months ago by Andrei K

Resolution: fixed
Status: newclosed

v9.1.23 indeed requires 4.34 drivers. Everything works with v9.0.20.

Thanks a lot! And sorry for bothering, in the end it's my inattention.
