Bug Report Dropping tons of frames and bitrate blinking red

Hi,

Me and many other streamers started to have a serious problem just last night and ONLY last night and forward. We get an insane amount of dropped frames (around 50%) and bitrate keeps blinking red with no indication of what the problem could be.

Is there a solution to this soon? I had to install xsplit to be able to stream again :(

If nothing change in OBS' settings and there is no reason to assume a problem with your connection then the most likely culprit is whichever streaming service you are using.

I am going to assume this service is Twitch. In case this is true; Twitch has seen a very sharp decline in their quality of service in the last 72 - 96 hours.

As I mentioned above, it works with xsplit and I'm not alone.

Several friends have done the same test, we had huge lag with OBS, none of us had ANY lag with xsplit. It all started for us last night as well so I agree that at first I'd point towards Twitch but I'm going to twitch via xsplit that works fine.

There was an update today on OBS so I will try that first on the stream because I really do not want xsplit. OBS <3

Really, it is a simple process of elimination. Again, did nothing change on your end? Then obviously it is not OBS directly. To give an example of just how poor Twitch's quality of service has become -- I cannot watch a single stream at 'Source' quality. Not a single one. Not even one that is streaming at 900 Kbps ('CosmoWright').

And no, that is not on my end -- 150 Mbps symmetrical which actually easily manages to maintain that speed over extended periods of time. Twitch... really... is... twitchy lately. Sorry.

I am very aware of twitches poor quality of late, I stream 4 hours a day on it.

It is now fixed and here is the whole summary of the why:

First off, it WAS the OBS softwares fault. Yesterday the stream went offline for no reason and could not get back up, I rebooted my machine and got a bluescreen because OBS had a crash with kernelbase.dll (Yes, lots of threads about it). Ever since I could not stream a single minute and not get 50% dropped frames while it worked just fine with xsplit.

I just updated to 0.552b and problem solved, I can now stream again. Yes, I tried streaming before I updated and I had the dropped frames still.

In conclusion sh!t can happen even if you don't change any settings. I am happy that I can stream again however and I've confirmed this with all my friends, it WAS something in OBS that messed all up last night for everyone and now it is working after the update.

New update fucked something up.

Dropped 50% frames + blinking bitrate. (0.553b)

Went back to 0.552b and not a single problem.

Somehow I kind of expected this to happen. Could you try/confirm a couple of things? Because I really suspect it actually is Twitch.
  • Confirm your Twitch.TV timezone, make sure it actually is your actual timezone and try and stream to a server within that timezone.
  • Reset your stream key (Dashboard -> Streaming Apps -> Show Key -> Reset Key) and wait half an hour before using that new key.

I had this problem last night, too with 0.553b. It appeared to me as a problem with the connection to a certain Twitch.tv server. Amsterdam, NL was my previous streaming location, but I had huge packetloss and also the bitrate indicator had it's colour jumping around like there's no tomorrow. However, after playing with all the settings, changing the streaming location to Frankfurt, DE, the packetloss was gone.
But the thing is, that the bitrate display should not be jumping around when the bottleneck is at twitch's side, shouldn't it? It should only drop frames in case OBS does some bad stuff, or my local connection is not able to send the required amount of packets, but my connection was totally fine.
Haven't tested 0.552b though, so I can't compare those two.

Tried streaming some world of warcraft today and I was also dropping 50-60% of frames like you guys (pretty sure this was after OBS prompted me to update it, I had updated it but didn't try streaming till now). My last stream a few days before was around 3:30 hours long with 0 frame drops so I'm pretty sure its not from my side.
