Question / Help Nvidia NVENC

cKy · Feb 5, 2014

Hello,

I was hoping someone could help me out with a little issue I am having when using the Nvidia NVENC..

Seems that when I stream with this function enabled it doesnt actually stream to Twitch.. its quite hard to explain but I dont get any feed on my channel even though it says 'Live' and I get an error on Twitch stating that my CBR is not set even though it is.

Error

The broadcast is not set to constant bitrate (CBR). [Current average: 94 kbps, current max: 328.0 kbps]

And a recent a log file from the failed stream http://pastebin.com/aTDapvES
recent log file from a successful stream (Not using NVENC) http://pastebin.com/WjdrsxwZ

when this option is disabled it seems to stream OK.

Thank you for your help.

You need to use the appropriate DLL from viewtopic.php?p=57445#p57445

Oh sorry I didnt mention that, I am using the correct DLL as the OBS would not start if this was not the case.

Thank you

dodgepong · Feb 5, 2014

OBS would start if you didn't have a DLL with a license key. In fact, OBS comes with a DLL that doesn't have a license key by default. Make sure when you start OBS that the self-updater doesn't overwrite your DLL.

BtbN · Feb 5, 2014

OBS starts fine with a DLL without a license key.
The log you posted shows clearly that the license got rejected, which most likely means you're not using the correct DLL.

Ah right, I will attempt to reinstall and re-advise.

Also I mean the streaming function not the actual application - apologies for the miss communication.

I will try it now.

cKy · Feb 5, 2014

OK I have ran two more streams at two minutes each..

Nvenc enabled and the said problem happened again - http://pastebin.com/rRDs2KkX

Without the Nvenc enabled I get a successful stream with no issues - http://pastebin.com/Gt42TG0Z
and all errors are removed.

BTW Im not attempting to cause trouble, please understand that I am very new to this and I dont really understand what I am doing- I was told that I would get better performance out of the NVENC feature which when it worked, worked bloody well.

Thank you

Set your preset to Low Latency High Quality, High Performance looks horrible and is gonna cause you Trouble.

Thank you Btbn I will try that now and see if it makes a difference.

Hello BtbN

same issue, Logs here - http://pastebin.com/QX5Ne5SX

I think I will try the 32 bit software and see if that makes any difference

Seem to be getting the same issues even with 32bit...

If you drop to 30fps with NVENC does it work?

OK to let you know it seems a mate of mine had the same issue before he suggested I try this new feature in a beta incarnation of OBS.

So if you're running the latest and greatest Nvdia drivers the API for the NVENC only allows 30fps 332.21 - WHQL

but if you use 334.67 - BETA it allows you to stream at 60fps while using that feature.

I will confirm this tonight but I thought if anyone else has this problem there may be a workaround for it.

Ahhhh cool, please let us know!

PermTrouble · Feb 6, 2014

Are you guys seeing a nice quality from nvenc?

alpinlol · Feb 6, 2014

lets say it this way... low latency high quality with 3500 bitrate 720p60 looks around x264 2000-2500 bitrate depending on the picture movement

Question / Help Nvidia NVENC
