Bug Report OBS disconnects when streaming Portal 2

Hi -

Whenever I try to stream Portal 2 (through steam), OBS will continuously disconnect/reconnect. After streaming for a while, I noticed the problem and when I went to check the automatically saved vods, there were numerous ~15 second clips.

-I'm using v0.461a, 64 bit.

-streaming to twitch.

-using the "Software Capture" source and tried a couple of the different settings in there (inner window, outer window etc).

-only happens when streaming this particular game. I can't say 100% it doesn't happen on any other game, but I've never had this problem while streaming roughly 10 other games.

-I also noticed in the vods that even the few seconds that it did capture were incredibly choppy and unwatchable.

It shouldn't be a hardware performance issue because I have no problem streaming other games with similar graphics in 720p at 60 fps.

Please let me know if I've failed to include any important info and thanks for any help!

Hi guys -

Thanks for the responses.

I did just update to .466a and it was still doing it.

I'm including the text from the log file from the session I just now streamed using .466a for the purpose of testing.

Well from what I can see in those logs, your connection to the streaming server you chose is most likely not able to handle the high bit rate you are using. My guess is that portal 2 has a lot more action on screen than the other games you have been playing, which is causing the encoder to get closer to the 6000kbps bit rate you chose. Something else to note along with this, is that a good number of people who watch twitch streams may not be able to handle watching a 6k bit rate stream unless you are a twitch partner and have lower quality selections.

Of course this is all just a guess until Jim can take a closer look, but my recommendation just for testing purposes would be to lower your bit rate and buffer to around 2000 at 30fps just to see if that possibly fixes the problem. I typically run my stream at 1800 and rarely have any quality issues.

There's really no reason to go above 3500 for 720p60fps. 6k is way too much. There's also little reason for your buffer to be larger than your bitrate.

Ok, I'll try lowering it. I have pretty fast internet (+10 upload) and didn't think there any downside to having it high. I guess I was very wrong!

That being said, I'd LIKE to avoid lowering the fps. Switching to OBS has kind of got me hooked on streaming at 60fps. If I were ok with streaming at 30fps I could just use xsplit, which doesn't have this disconnecting problem.

Not sure if this is related to the disconnect issue or not, but you could try using game capture. Monitor Capture on windows 7 is kind of meh, especially with Aero enabled. Your frame process/encode times are really high because of the capture method you are using. Again, not sure if this is going to solve a disconnecting issue, but you may as well get everything trying to run as smooth as possible.
