i have a constant upload speed always above 10 mbps but whenever i start my stream the bitrate stays normal for 2 to 3 seconds and then starts decreasing
for example i have set my bitrate to 7000kbps cbr
i pressed on start streaming
the bitrate is stays between 6500 to 7000 for few seconds
than starts decreasing and then goes between 1000 to 2000 kbps
that time i check my speed it is good
why is this happening?
any soln....
plzzzzzzzzz....,.,.
btw i stream on YT..

Disable the bitrate auto-adjustment in Settings->Advanced->Dynamically change bitrate to manage congestion.

Sites like speedtest.net are worthless for livestreamers. They measure peak speed only, not minimum speed (which streaming relies on). If you are on an intermittent connection, it will cause issues. If you are trying to stream over wifi, DON'T. Use a wired network cable instead.

Estou com o mesmo problema, ja desabilitei tudo, fiz todas as configurações possíveis, inclusive fiz troca de maquina, com outro computador e o problema persiste.

But
Its happening after the obs update
I streamed before but there was no dropped frames etc ....
And stable bitrate....
????

Updating OBS would not cause that.
The problem is, when it comes to the internet, 95% of your connection is completely out of your control. Your connection is routed from server to server in a chain of hops. If any of those servers start having a problem, your connection is affected without anything changing on your end.

You can try unplugging the power to your modem, waiting a few seconds, and plugging it back in (and any local network switches). Sometimes a simple restart can fix problems if they are on your end. Many 'home routers' can soft-fail from time to time, and a reboot can get them working properly again.

today i streamed on youtube using the slobs mobile app
i choosed 10000 kbps bitrate
started stream
the bitrate was stable (stuck at 10000 kbps)
is streaming from mobile diff from pc???

Guyssss guysss
I think i solveeddd ittt
The prob was the update of obs
I downloaded an older version of obs
Now its good
And always disable the preview before streaming if u r getting problems like me

i have a constant upload speed always above 10 mbps but whenever i start my stream the bitrate stays normal for 2 to 3 seconds and then starts decreasing
for example i have set my bitrate to 7000kbps cbr
i pressed on start streaming
the bitrate is stays between 6500 to 7000 for few seconds
than starts decreasing and then goes between 1000 to 2000 kbps
that time i check my speed it is good
why is this happening?
any soln....
plzzzzzzzzz....,.,.
btw i stream on YT..
1- Turn ON Game Mode in Windows settings.
2- Run OBS in admin mode.
3- Download codec AAC, link: Apple codec
- No install !, extract with Winrar to any folder.
- Inside folder, install only AppleApplicationSupport64
- Reboot PC

OBS settings for streaming with NVENC encoder:

Output:
Encoder: NVIDIA NVENC (new)
Bitrate for 60 fps 1080p: 6000 kbps (Twitch official recomendations)
Keyframe: 2
Preset: Quality

I made a video about this

Youtube re-encodes all videos and streams, if you are a small channel then Youtube uses an old and significantly worse codec (avc) to encode the videos. This makes the video look much more pixelated than it should be

if you're a bigger channel (which is why you never see this problem on big youtube channels), Youtube automatically uses the newer and significantly better codec (vp09) in your videos and streams. This makes your video lose almost no quality at all

to force Youtube to use the vp09 codec, you can stream in 1440p or a higher resolution

doing this with videos is okay because you can record at any resolution and render it in 1440p in any video editing software

but with streaming, you have to stream at 1440p which your computer may not be able to handle

if you want to check out my video then here it is:

ok the soln that helped me
downloading old version did'nt (my bad)
so this helped me
i use lan cable to connect my pc to internet
1. go to start
2. type ethernet settings (open it)
2. click on change adapter option
3. disable the ethernet driver and enable it
this thing helped me
now i have set my bitrate to 8000 kbps
now my bitrate is stable
always between 7000 to 8000
0 dropped frames
try this.....
hope this helps.
reply if this thing helped u..
