Question / Help High dropped frames when launching my stream while good bitrate and NVENC encoding overloaded?

Hello,

It's been few weeks now since I'm fighting with OBS Studio because of dropped frames. One day I started my stream, my bitrate was normal and green and 2 minutes after it goes red and 50% dropped frames appears. I cutted my stream, made a speedtest and my results were good : around 20mb/s uploading. I tried to change server, reinstall OBS, use the beta version and my problem disapear, I can't explain how. But today, it's back. I started my stream with the ?bandwidthtest=true, trying different settings like x264 as you can see in the logs
https://obsproject.com/logs/7mVvSatTgnVoHjRg
"16:29:13.314: Output 'adv_stream': Number of dropped frames due to insufficient bandwidth/connection stalls: 323 (57.9%)"
I checked my connection before and after with a speedtest again and everything was fine but in OBS my bitrate barely reach the 3000kb/s

After that I restarted another stream at 16:50 and now everything is fine.

Also, while streaming those last days, I've seen "Encoding overloaded", I have a 1080TI 11GO. I've been using the same settings for few months now with no problems, I had to change with the old Nvenc to solve it. If someone knows if it's a bug or what I would like to know :).
Thanks in advance for the help :)

So a few things. New Nvenc only slightly helps performance on cards older than to rtx and 16 series cards. You do not get the quality increase like they do since they have a new physical chip. So using old nvenc is perfectly okay. Your issue seems to networking related. But what did you use for a speedtest? Not all servers are in the same place and do not have the same connection to you. Use this to find your actual speed: https://r1ch.net/projects/twitchtest

No, he is right. TwitchTest reports the quality of your connection to Twitch there is *zero*. The jitter is irrelevant. The bandwidth reported is significantly under 10k. That is only the claimed rate for the last mile from your ISP. It has almost nothing to do with what quality or speed of connection you will actually experience to any particular server on the internet. It might be your local network and not your ISP, but it also likely not OBS.

Also, your log shows connection to Restream and not Twitch, so even the TwitchTest result is not valid. But the low quality result does not indicate your connection is good enough to stream with, and generic speedtest results are also not relevant.

18:21:43.776: [rtmp stream: 'adv_stream'] Connection to rtmp://sa.restream.io/live successful

I also don't see that ingest server listed with Restream. Maybe check here for the best one?

https://restream.io/speed-test

Possibly saopaulo.restream.io instead?
 
That's still not relevant.

Also, 3970 < 10000.

Also, streaming on wireless is not recommended.
 
If you stream on a cable then you also need to run TwitchTest on the cable, otherwise the test was useless.
 
Your log says your internet connection is not fast enough for your selected bitrate:

15:25:04.773: bitrate: 5300

15:25:12.889: Output 'adv_stream': Number of dropped frames due to insufficient bandwidth/connection stalls: 29 (6.6%)

You've selected 5300 and about 7% are dropping which indicates. your actual connection speed to your selected server is ~5000, which is higher than your TwitchTest result, but lower than your selected bitrate. Try 4500.

You can contact your ISP to complain but the speed they give you is for their connection from their network to your laptop, not from your computer to any other specific server on the Internet. It is absolutely normal for less than half of a claimed connection speed to be practically usable for streaming.

I always do stream with 6000, 7000... if i reinstal windows with the ''old version'', OBS work normaly! Don't have that limit 4000 mpbs, and doesn't matter i put the 2000 mpbs ou 3000, The instability on stream is too crazy,
it seems it only lasts longer before it happens again. I tested other PC's and highest internet have in Brazil, the results is the same!

If what you are stating is correct and using an older version of windows is working for you, then use the older version of windows.
 
15:25:04.790: [rtmp stream: 'adv_stream'] Connecting to RTMP URL rtmp://sa.restream.io/live...
15:25:04.813: [rtmp stream: 'adv_stream'] Interface: Realtek PCIe GBE Family Controller (ethernet, 100 mbps)
15:25:05.422: [rtmp stream: 'adv_stream'] Connection to rtmp://sa.restream.io/live successful

The manufacturer to your motherboard could have supplied the wrong version, Microsoft is using a wrong version in its database version cache, etc. for this Windows build 1903. Go to the motherboard manufacturer and download the current Ethernet NIC driver. Do this to overwrite the existing network driver installed that may be causing the problem.

Reboot, and then, run a stream test to:

Twitch Brazil
YouTube South America

If that fails, go to Realtek and get the current NIC driver. Always do the motherboard driver first and then if that fails, Realtek.
