NVENC h264 works, but not h265

Post by RedAero »

Description of problem or question:

I have the same exact problem as was reported in this thread, except I have a different GPU and the latest drivers.

In short, using H.264 with Nvidia NVEnc works fine, using H.265 Nvidia NVEnc fails with the error shown in the log:
[hevc_nvenc @ 00000190f6d08940] No NVENC capable devices found

As you can see here, the M2000 series does support H.265 compression (click the Quadro button on the bottom) with the latest drivers, which I installed on the day of writing.

Steps to reproduce the problem (If Applicable):


HandBrake version (e.g., 1.0.0):

1.2.2

Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):

Win 10 Enterprise x64
10.0.16299 Build 16299

We are not supporting anything older than Pascal I'm afraid. Your GPU doesn't have the full H.265 capabilities so it's most likely failing because we are initialising with capabilities it doesn't support.

We still have an open ticket to implement proper hardware checking on NVEnc so unfortunately the encoder shows up, even when it's not going to work.

Your system does have QuickSync H.265 supported so I'd recommend using that. Generally does a better job if not quite as fast.

That's a pity... Is there compression software that does support H.265 on this model of GPU? I mean, I have it, I might as well use it.

GPUs are not good at encoding/compression. Even the most recent "GPUs" do not match software encoders for quality. And the only way that "GPU" encoding has gotten fast is by the hardware manufacturers adding a dedicated hardware encoder that sits on the same silicon as the GPU but in no way contributes to the GPUs regular function of rendering and displaying graphics on the screen. These are really separate co-processors designed specifically for encoding video and not a "GPU".

NVidia has a CUDA based encoder that actually uses the GPU for encoding that might work on your hardware. But HandBrake has never supported encoding with CUDA because the results were so awful. It is not particularly fast and the quality is really poor.
