[opensuse-factory] CUDA on Tumbleweed and HEVC/H.265 decoding
Is there a way to install Nvidia CUDA on Tumbleweed? (The official download site https://developer.nvidia.com/cuda-downloads lists only openSUSE 13.2, SLES 11 SP4 and 2. On https://software.opensuse.org/package/cuda-8.0 there are unofficial packages from the Bumblebeed project. I have a Nvidia Geforce GTX 750, which supports H.264, but not H.265 over VDPAU.) I tried the openSUSE 13.2 packages. They install, but it seems, that they do not work. $ mpv --hwdec=cuda hevc-testvideo.ts (+) Video --vid=1 (hevc 1920x1080 50.000fps) (+) Audio --aid=1 --alang=deu (aac_latm 6ch 48000Hz) Audio --aid=2 --alang=fra (aac_latm 2ch 48000Hz) Subs --sid=1 --slang=deu,deu,fra (dvb_teletext) [ffmpeg/video] hevc_cuvid: ctx->cvdl->cuvidCreateDecoder(&cudec, &cuinfo) failed -> CUDA_ERROR_NO_DEVICE: no CUDA-capable device is detected Could not open codec.

/dev/nvidia* writable by the user? Are you even able to run the cuda system monitor program (nvidia-smi)? -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Sounds like a permission issue. Make sure the nvidia-uvm module is loaded and your user is a member of the video group. Note: the GTX 750 will not support HEVC via CUDA either. GTX 750 SE (which is a newer model) does. It won’t work if vdpauinfo doesn’t show at least the HEVC_MAIN capability. CUDA only adds is 10-bit support. You don’t need to install the CUDA SDK to use the CUVID functionality that is needed for hardware decoding. Also, CUDA has known bugs. 10-bit decoding is broken in various ways (don’t expect Rec. 2020/HDR to work) and even 8-bit will not always decode correctly. Expect frame corruption, flickering, random lines of garbage at the bottom of the screen, and juddery playback because CUDA messes with the timestamps. Blame NVIDIA.

I found out, that "mpv" with --hwdec=cuda works perfectly with H.264 videos on my graphics cards. The answer from svencdack shows additional details: https://devtalk.nvidia.com/default/topic/971350/cuda-hw-acceleration-works-f... Unfortunately there is a regression in Nvidia driver. Currently I use 384.69 from nvidia-tumbleweed repository. With some older Nvidia driver versions, I had VDPAU as "Current Video Playback Profile" for the MythTV frontend. This worked perfectly for H.264 videos and OK for H.265 (CPU usage was relatively high and sometimes I had audio/videos dropouts). With my GTX 750 H.265 decoding was done with CPU and additional filtering and video playback was done with the VDPAU driver. Now with Nvidia 384.69 the display is completely black for H.265 videos. It still works with H.264 videos. As a result I can not use the VDPAU profile anymore, because I use H.264 for downloaded videos and H.265 for live and recorded DVB-T2 HD videos in Germany together on the same PC. I am not sure, where I should report this problem.
