Question / Help Nvenc / Twitch / Green screen

tiphergane · May 27, 2014

Hello all,

First, if I missed the answer in an other thread, I would like to apologyze.

Ok, my problem is when I want to stream with OBS and nvenc, my stream show a crappy green video

http://www.twitch.tv/tiphergane/b/532612251

My GPU is in the compat list, so normaly I must use nvenc ...

Code:

Use the sticky posts in the guides forum to set up your stream. Don't use NVEnc for streaming, its only really suitable for saving to disk only, not streaming.

If you have the same problem with x264 encoding after following the guides to set up OBS, then post again with a new log file from that attempt.

flavored · May 28, 2014

Please set buffer back to default. Please use x264 encoder, as NVENC requires a huge bitrate to output in a decent quality, thus is not suitable for online broadcasts.
Have you tried removing all the other sources except your game capture as well as not downscaling your resolution? Does the problem still persist?

tiphergane · Aug 31, 2014

Thx guys for your answers, I've set back to x264 because it's smoother while streaming.
