I have an issue where every 30seconds - 45 seconds or so (twitch.tv) my viewers will complain that video hangs for a second or so but audio is fine. I check OBS and drop 0 frames during everything. I first ran into it playing Farcry3 and I tried isolating the issue and seeing if it was just the game, but I tried DOTA2 last night and same thing. I've checked all my settings, and my Upload is 5/mb and Ive currently have it set to 2500/2500 on bitrate and buffer. Didnt have this issue with Xsplit. Any recommendations?

Also noticed in one log that its 32bit? Im using 64bit Windows7.

Were you restarting stream manually or OBS was doing that? Make sure you're streaming to the nearest server and not Global Loadbalance.

I was streaming, noticing video issues on TwitchTV, and stopped it and restarted with different bandwith values to see what the problem was. Check them out: twitch.tv/dc2587

EDIT: Facry3 ones, about 1-2 mins in length each

Edit 2: Ok, video playback shows no hangups when playing back...only when streaming which is the frustrating part.

In addition to that, Picture quality isnt what I expected for 2500kbps@720p. Ive seen much better picture clarity on worse machines/internet same resolution. :(

The quality itself depends mainly from x264 preset. Slower ones will produce higher quality video. Are you sure it's not your wiever's problem? If VOD plays ok, so it shouldn't be your problem. Check with JTVPing, which twitch server has the least ping and make sure you use it in OBS.

If you're getting "pauses" in your stream that don't show up on the vod, that typically means that you're having network congestion, and the app isn't dropping frames when it should to compensate. Sometimes this can happen where the app doesn't drop frames when it should, depends on the situation. If this is the case, then my recommendation would be to try lowering the bitrate for now to see if that helps at all

Ill give it a try, thanks. I lowered to 2,000/2000. Should be fine in either situation, on a 5mb upload.
