Xpra: Ticket #1519: xpra-15876 and NVENC v7: init_cuda fails for h264

Hello all!

I have a problem with Xpra and NVEnc.


Server; 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

Client: 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.
