QuoteBecause of its improved performance and quality, NVIDIA is focusing all future video encoding development on NVENC, which is the dedicated encoding hardware engine first added in Kepler family of GPUs. NVIDIA no longer supports NVCUVENC, which was the CUDA-based video encoder library. NVENC is replacing the earlier CUDA software-based NVCUVENC driver module. On Quadro and Tesla, 341.05 is the last driver to support NVCUVENC. NVCUVENC will not be available with GeForce after R337.

QuoteSupport for HEVC (H.265) encoding on GM20x GPUs (GTX980 and future Quadro/Tesla/GRID platforms based on GM20x GPUs)
Would this exclude the GTX970 and GTX960 as a valid option?
What would be the minimum requirement for avidemux 2.6 branch to keep up with progress?
Seeing these avidemux developments:
- Encoder: nvenc through ffmpeg
- nvenc/core
As for now: just put my new video card purchase on hold* prices shown, researched/found by me on 2015/03/29 based upon (Netherlands pricing)
I only buy passive video card for my main desktop
So i wont be using the h265 encoding unit for some times
On the other hand, the h264 one seems to work fine with low cost cards as long as they are recent enough (and not older gen renamed)
It's not 100% working yet
Fair enough.
I seem only to find semi-passive GM206 (GTX 960). Require 4K output for gimp photo editing.
Complete passive would be GTX 750, but these are only Maxwell GM107 instead of GM2xx.
Perhaps something like asus GTX750-DCSL-2GD5 (with display port) 750-ti has no display port. Still have some months before buying (June - July upcoming summer sales)
Just found out, still need testing.
GT 520 is still supported with:

I'm now rebuilding avidemux against this driver.
Are other requirements needed?

would the SDK Updated (NVENC SDK 5.0): Janurary 31, 2015 satisfy the requirements?
installed: cuda (7.0-28)
now trying with cuda-*-6-5
driver >= 346
nvenc SDK 5.0
Have both and was able to build the samples.
I understood I needed to place the file nvEncodeAPI.h into /usr/include/x86_64-linux-gnu
avidemux did build when it found nvEncodeAPI.h
Anything more needed from nvenc 5.01 sdk? And where do I put those?

Trying to encode with default settings, brings this pop-up window:

ffnvenc should work now

could there still be an issue:
I manually copied nvEncodeAPI.h into /usr/include/x86_64-linux-gnu
Is there a procedure to install nvenc correctly?
It's trying to load :

I dont think your video card supports nvenc
I had a 610GT which is similar and it was not supported
That would explain this.
So we are back @ minimum requirement would be an nvidia GPU GM10x or GM20x
