Hi All,

I've been streaming with OBS for a few weeks, and loving it so far, but I am getting stream drops around every 20 or 30 minutes.

I'm using window capture with Starcraft 2, streaming at 720p, 30fps. I was streaming at 60fps before, and having the same issues. I've turned Max Bitrate down from 4000kbps to 3300 kbps after doing a 32Mb upload speedtest. I've also tried a few nearby Twitch servers, specifically, both LA serves and the SF server, but no luck!

Computer specs:
Haswell Core i5 @ 3.4 Ghz
16GB ram
Nvidea 550Ti

Any advice on other settings would be welcome!

Logs below.

Re: Stream disconnects intermittantly. Occasional frame dro

I should also mention, in addition to the window capture, I'm also including webcam capture at 720p. I am also frequently using Google Hangouts simultaneously to voice chat with people I'm playing with.

Implying that for some reason or another Twitch is dropping the connection. And given the fact you weren't dropping frames up until then I am inclined to say the problem is not yours to fix. However, I do have a couple of suggestions:
  • Restart your modem and/or router
  • Reset your Twitch.TV stream key
  • Make sure that the timezone for your Twitch.TV account is the same timezone as the server you are streaming to.

I've seen you suggest this multiple times and I'm just curious as to why?

Re: Stream disconnects intermittantly. Occasional frame dro

Because it has been known that this causes issues with Twitch.TV, on occasion. This recommendation actually comes from Twitch.TV Support. Apparently there are cases where the Twitch.TV servers start misbehaving when there is a mismatch between account timezone and chosen stream server.

Interesting, and good to know. Do you have a link to this for reference?

Re: Stream disconnects intermittantly. Occasional frame dro

Hey, guys. Sorry for no reply on my end! I guess I don't have my OBS forums account set up to send me email notifications, whoops! My IRL timezone, Twitch account settings timezone, and Twitch server timezones all match, and furthermore I have tried all the servers in this timezone!

I guess this is a bug report to send to Twitch then?
