Question / Help obs says no dropped frames. latency bar is always red and capped at random speeds..

whenever i try streaming, if there is action going on, my stream begins to freeze and skip. obs detects no dropped frames. it does however have a red latency bar for the entirety of my stream and i'm unsure why (that only started recently). i've tried switching ingest servers and the issue persists.

the bitrate i have set for audio is 128, so it shouldn't be 2022kb/s should it? either way, even when its not over 2mb/s the bar is still completely red.


i have an i2500k @ 4.8ghz
gtx 760

upload speed : 2000 (i set it to 1680 in obs)

streaming to twitch.tv

here is my log : https://gist.github.com/7df892e4b68708fc6c67y

i have also been reading the forums and downloaded shaperprobe to see if i was being throttled, but it detects no throttling :

i have also used testmyupload and tried the 6mb test:

not sure what else to do here. i don't think its me.

the link to my log expired, here it is again

also, im currently using the windows 10 technical preview, but the issue also exists in windows 7 and 8.1.

Speedtest sites (including shaperprobe) use a different type of connection as compared to livestreaming. It appears that your connection is not able to maintain stable single-link throughput. Bitrate will surge when the buffer fills (the red box is an indication of this) to try to empty it, overwhelming your connection even moreso as the rate is apparently set too high. You were dropping no frames at 1000kbps, but a ton at 1680. Also, make sure that your tests are at least 5 minutes in duration to allow things to 'settle in' and normalize.

Short version, you'll need to back down your bitrate further until you establish a stable baseline, and are advised to dial it back by another ~10% minimum after finding that point to allow for network fluctuation. I'd probably start at 1500kbps. Similar, be aware that the bitrate setting is ONLY your video bitrate, audio is handled separately. I would advise 96kbps AAC for that.

So yeah, your connection can't actually handle streaming at that rate. Streaming uses a single-link connection, speedtest sites use multiple to maximize your connection's potential throughput. The only thing a speedtest site reliably tells you as far as livestreaming goes is that you have a live connection to the outside world, and maybe a semi-spitball.

that makes sense but the thing is i was able to stream with these settings (1680 bit rate) just fine last week.

Networks fluctuate. It's not a rock-steady, reliable thing. That's why you don't run at the bleeding edge of what you can get, you put in at least a 10% margin. Generally it's not advised to stream at more than 75% of your 'rated' speed unless you have a REALLY good ISP. Even then, you have to keep an eye on it in case there's an issue further upstream.
