Question / Help General info about slow network

[linktoheaven]

So this is my network speed



Its nothing special and i know i cant do much with it but i was playing around with OBS and my friend that was watching my test stream noticed that no matter what quality i put up (360p-1080p) it has same spikes. It goes well for 3-4s then 1s spike.

I know my network is slow but it made me wander, how is it possible to have same spikes no matter how bad or good stream is. I was expecting it to work better with lower quality and worse with better but it stayed the same.

P.S. Here is my log file:

The way it works is it sends out a bulk of information every so often. That is usually why it seems to spike in waves.

 

[Bensam123]

Try using CBR as it's more consistent and spikes less.

I don't think you'd be able to stream 1080p or 720p on that connection though, more then likely 480 or 360p. When making a post make sure to post your log file as well so we can see what settings you're using.

I am using CBR and i know i shouldnt be able to stream on 720p-1080p but the consistency of spikes at any quality is what bugs me.

 

[Bensam123]

Ahhh... good to know...

Have you tried the 'minimize network impact' option buried in broadcast settings? That really helped me. Before that option I would spike about every 5-10s from my normal ping up to 10x it. Your bit rate should be under your cap definitely though and you may even want to leave some breathing room.

The issue is you are streaming above your available max speed (1000 Kbps) for video and have audio set at 128 Kbps bringing your total requirement to 1128 minimum. Alone that is almost 400 Kbps over your available bandwidth.

Lower your output to:

852 x 480 in the resolution downscaler in the video settings.

Lower your framerate to:

15 - 30 FPS

Lower your max Bitrate (Settings > Encoding) to:

600

and you'll be on a better path.

You WILL NOT be able to stream at 1080p at anything other than MAYBE 1-10 frames per second. Trying to stream at even 720p in a reasonable sense is beyond your bandwidth.
