Today (17.5.2013) I haven't been able to stream to twitch due to the stream starting to drop frames 5 seconds after starting the stream. I've tried everything, 120p with max bitrate set to 100kb/s, all the different servers and nothing works. And the funny thing is that I can stream perfectly at Livestream(dot)com.
Here are my usual settings which I've used in the past and had zero problems:
Max bitrate: 3900
Buffer size: 4200
Server: London UK (secondary)
My upload speed is 9mb/s. I live in Finland.
Thanks in advance,
