Question / Help Frequent disconnects with OBS

Hello,

I've switched to try OBS from xsplit only today, and was immediately impressed with the fps gain. However, after streaming for a little while I've encountered a huge (breaking) issue: after a little while of streaming (from 5 to 20 minutes) framedrop rate would start rising quickly (unnaturally) to 50-70-100% and eventually a connection would drop. After a reconnect, the video might be all black (or it might not be, seems to be a random effect). At first I thought it might be my internet, lowered my bitrate, resolution, etc etc, switched to a scene with only one picture in it and left it alone for a little while to stream - same thing, after a short while, framedrop would go sky high and I would get disconnected. I then ran ping, traceroute as well I tried it back with xsplit - everything was normal. I stream to twitch.tv and thought I might be having certain issues with particular server, then I tried all 4 european servers but every time the result was the same. I tried going through google or this board but haven't found a similar issue (yet). Could someone provide any support? Thank you!

P.S. Tried with both stable latest version as well as the latest alpha, no change.

P.P.S. Another important thing I forgot to mention is that when this glitch occurs, the video on the stream freezes completely, but audio continue uninterrupted. That is, until it disconnects.

Please post a log.

Based on the symptoms you have described, it certainly sounds like the connection to whatever servers you are trying is being choked. This unfortunately seems to happen to a lot of people on weekends in Europe. Could you do me a favor and try one of the Ashburn servers just to see what happens?

Hello,

Thank you for your reply, posting the log at the end. As I mentioned before, Xsplit performs just fine, no disconnects or frame drops. Same overall settings, just lower fps ingame. I will try the servers you mentioned.

Memory Leaks Were Detected.

P.S. I have tested the servers you suggested and the result is the same, this time faster though. Every 1-3 minutes I get framedrops and a disconnect.

OK, wanted to add in that version 0.465a is perfectly stable. But I can only capture all the desktop there, game capture doesn't work at all. But I can stream without disconnecting.. More testing to come.
