Do you have a license or are you using the DLL BtbN provided? Otherwise it won't work.

Re: 0.60 test build 6

Everybody that needs the DLL go back to Page 2 on this Thread and scroll to the bottom. A user has provided the DLL needed :-)

i try to use dlls from 2nd page and dll from archive with test build, both dont work on 32 and 64 bits

The newest test build contains support for Nvidia NVENC.
In order to use it you either need to set the environment variable NVENC_KEY with a valid nvenc license key in standard GUID/CLSID format, or download a precompiled binary with a license key already built in.

You can download them here:
64bit OBS: https://btbn.de/files/64bit/ObsNvenc.dll
32bit OBS: https://btbn.de/files/32bit/ObsNvenc.dll

Just place it in the same dir as OBS.exe, replacing the already existing one. It's not a plugin, so it doesn't go into the plugins dir.

Keep in mind that this feature is still quite new and experimental, but works fine in general. Any kind of feedback about this is highly encouraged!

You need a Kepler GPU(series 600 or better) to be able to use this.

It doesn't work!

I just pulled the latest code from github, compiled. Copied the dll over. but nothing. Always greyed out.

Are there any logs from the init/startup process available? I don't see anything in the normal log file directory.

edit: Same when I use your latest test build binaries (not compile it myself) + the linked dll

edit2: just checked with the guys on IRC. Probably the licensed 64 bit version of NvEnc (from BtBn) is broken.

Everything seems to work on 32 bit, but on 64 bit it complains about license.

Here is the log (I forced the checkbox ON in the code):

Hi,

so I tried NVENC out and stream on twitch wont load at all. Is that on purpose, on twitch's end or did i do something wrong?

Re: 0.60 test build 6

Furyliciouz everything looks like its working just fine. If you can't load your own stream then its an issue with twitch I suppose. Especially if there is a vod of the stream afterwards.
 
#48
Re: 0.60 test build 6

I've got NvEnc working fine, but like others have reported there is a sever lack of quality associated with it at this moment. I am really looking forward to seeing what it can do though.

As an aside, It didn't like trying to encode 1080p@60 on my GTX 660 (non ti) which makes me a sad camper :(
 
#49
Re: 0.60 test build 6

All possible options are now exported and imported via two xconfig files in %appdata%\OBS , so everyone who likes can try to finetune the encoding quality.
The last_nvenc_config.xconfig file allways contains the options used on the last init. The nvenc_config.xconfig can be used to override some/all options. It uses the same format. Omitting an option in nvenc_config just leaves it unchanged from the preset default.
 
#52
Re: 0.60 test build 6

I'm like pretty Newb to the Nvenc lol so I'm going through all the settings and reading about them in the NVENC_RefManual. I have however been playing with Shadowplay and learning about it a lot lately.

I came across enableEncodeAsync and enablePTD and the Manual is saying:
The client should set NV_ENC_INITIALIZE_PARAMS::enablePTD to 1 for allowing the
HW encoder to take Picture-type decision. Set it to 0 if client wants to decide picture
type for encoded output.

Note: NV_ENC_INITIALIZE_PARAMS::enableEncodeAsync == 0 and
NV_ENC_INITIALIZE_PARAMS:: enablePTD == 1 are not a compatible combination.

In the stock setting PTD is set @ 1, should I put it to 0 or am I just over-reading into things atm lol?
 
#53
Re: 0.60 test build 6

enablePTD and enableEncodeAsync are the only two settings i ignore when reading back the configure file.

enablePTD controls wether nvenc automaticaly decides the picture type(I/P/B), and async mode is a diffrent mode of operation which i simply decided not to use.

PTD has to be on, and asyncMode has to be off, otherwise the whole code wouldn't work at all.
I haven't read anything about this beeing not a compatible combination. It works fine, so i assume that information is outdated.

there ya go, all shiny and loggy like

The highest I can go resolution wise seems to be 720p anything past that and I get the can't keep up error. Tried several framerates on that as well.
Yeah, so the preset llhq (low latency high quality) is really only meant for 720p as it is really taxing on the chip for whatever reason. If you want to do 1080p@60fps go to advanced settings in obs, tick and enable custom x264 encoder settings, then enter "hq" without the quotes in the field. This will change the preset of nvenc to one that will be able to handle the encoding. Since most people won't look at the github commits ill post the other presets here.

"hp" = high performance
"hq" = high quality
"bd" = bluray disk
"ll" = low latency
"llhp" = low latency high performance
"llhq" = low latency high quality (current default preset if you enter no custom settings)
"default" = default

Feel free to mess around with them all if you would like. Preset "hq" is good for 1080p@60fps up to around 50000 bitrate.
Higher the bitrate the more the encoder will chug and start to duplicate frames, so keep that in mind while testing.

Re: 0.60 test build 6

Ok so this option rateControlMode : 2 to which of these parameters corresponds?

NV_ENC_PARAMS_RC_CONSTQP Constant QP mode
NV_ENC_PARAMS_RC_VBR Variable bitrate mode
NV_ENC_PARAMS_RC_CBR Constant bitrate mode
NV_ENC_PARAMS_RC_VBR_MINQP Variable bitrate mode with MinQP
NV_ENC_PARAMS_RC_TWOPASS_CBR Constant bitrate mode using two pass encoding

From what I read NV_ENC_PARAMS_RC_TWOPASS_CBR is best quality and CLOUD_GAMING_720p30 is the highest quality preset...
