I am having issues getting even lower bitrate quality (bandwidth/upstream is not an issue) to stream smoothly to twitch. Any ideas from my logfile as to what could be the problem?
Here is an example of a recent stream that was particularly bad: http://www.twitch.tv/drew13btv/b/479507855
Yes I am aware my CPU is a significant bottleneck. But I am not even trying for 720p/30FPS here. I just want a decent smooth stream.
