Hello!
So I use an RTMP Server setup to stream occasionally.
On my gaming PC I use OBS to stream to my RTMP server and my server re-encodes the stream to send of to Twitch. It seems that OBS is losing frames. It is supposed to be outputting a solid 60fps but it dips into the high 30s occasionally.
Here is the hardware setup layout.
Gaming PC: i7 4770k + GTX 980
RTMP Server: i7 4710HQ + GTX 850
X264: CPU Preset Fast - 4500kbps - FPS 60 - 1280x720
Gaming PC ----[20000kbps]---> RTMP Server ----[4500kbps] ---> Twitch
You can see in the Photo OBS is outputting 40fps when it should be a solid 60fps
Also here is the OBS Log file:
