xpra-15876 and NVENC v7: init_cuda fails for h264

Reported by: Aynur Shakirov Owned by: Aynur Shakirov

Hello all!

I have a problem with Xpra and NVEnc.


OS: Arch Linux 20170517/Ubuntu 16.04.2
Xpra: 15876-svn (CFLAGS=-02 -march=sandybridge, with-nvenc7)
VCard: Nvidia Quadro M2000/K620
Nvidia Driver: 381.22/378.13/375.x
NVENC: 7.1.9
CUDA: 8.0.61
Encoder: H264
Xpra Command: xpra -d nvenc,scaling start --start=firefox --video-encoders=nvenc --encodings=h264

OS: Arch Linux 20170517
Xpra: 15876-svn
Xpra Command: xpra attach ssh/root@IP/0 --encoding=h264

Actual result

CUDA initialization fails for h264 encoder, only h265 works but very buggy as expected. As a result, if I connects to the Xpra instance with the h264 decoder I got a black screen for window.

Expected result

CUDA successfully starts for h264, client shows a app window correctly.

Logs and other files are in the attachment.

Thanks for helping.

@Aynur Shakirov: this should be fixed in trunk, works for me with a GTX 1070, see ticket:1550#comment:14.
