Question / Help 20mbps/ Still lag, Help Please!

I have a pretty good upload speed, and I don't understand why I still lag when I have an average bit rate ( I can't go past an 1800 bit rate.)

Wouldn't a 20mbps upload speed allow me to have a high bit rate? And whenever I stream at 1800 it doesn't look that great. So I really want to upgrade the quality.

Any help would be greatly appreciated

Here is my log.

3500 is pretty high. And with Twitch having trouble distributing high bitrates, especially in Europe lately, you might not want to stream at that bitrate. For example, I have 100mbps up/down, but I can't watch a 3500kbps stream without it stuttering like hell.

That said, speed tests are not reliable for determining your streaming speed. I could recommend other speedtests, like testmy.net for example. But in the end, the only real test is trying to stream. The only option you really have is to try some different ingest servers, and see which one works best for you.
 
Well even at a 2200 bit rate I still drop frames. But what I think the problem is that its my ISP, I have cox cable and I think they mess with my speed if I'm doing something pretty extreme with it ( like streaming. ) I believe it's called throttling? Do you know if there is any way to fix this? Because it only happens about a minute after I start streaming with a high bit rate. It doesn't lag immediately, which is odd.
 
That does sound like throttling yes. ISPs sometimes tend to boost your speed for the first few minutes to make the connection score higher on speedtests. This appears to be what they are doing. If you can indeed stream for about a minute without problems, then the Twitch ingest server isn't the problem.

Actually, one different server is a bit meagre, you appear to be in North America, so you could theoretically try any NA server. But like you said, your ISP might be the issue, then there's not much you can do about it, except perhaps contact them and ask them if they can do anything about those speeds.

Also, I don't know which game you are streaming, but 720p30 at around 1800kbps should provide a pretty decent image, unless it's very high motion. You might try going up a notch from veryfast to faster on your c264 preset to see if you can improve the quality a bit at lower bitrates, if your cpu can handle it.
 
Thanks for the help. At least I found the problem, but I will try "veryfast" and see if it helps. Thanks again : )
 
I would strongly recommend running Shaperprobe to try to confirm if you are being traffic-shaped or throttled:
http://www.cc.gatech.edu/grads/p/partha ... probe.html

Is that 20mbps what your ISP is telling you? Please run a 6MB test at http://www.testmy.net/upload to find out what you actually are getting as constant throughput.

Also, 720p@30 will run fine at 1500kbps; 3500 is ridiculously high. Especially if you're not partnered... you'll get a TON of complaints about stutter, buffering, and other problems. At most, I'd go 2000kbps on that res and rate; coincidentally the max recommended by Twitch for non-partnered streamers. A livestream will never give perfect 1:1 fidelity... there's a point where you simply have to manage expectations.

I'd recommend using JTVPing (http://www.teamliquid.net/forum/viewmes ... _id=326034) to find your lowest-ping local ingest server. A combination of that and a lower bitrate will allow for smoother streaming to a wider viewerbase (including EU from the US, or vice-versa). Unless it's the UK or Amsterdam, which is ****ed due to the UK ingest being down for 'emergency maintenance' for another few months and routing everything transparently to the Amsterdam ingest.

I'd also recommend dropping your audio bitrate to 96kbps or 128kbps at MOST; 160 is completely unnecessary and with AAC the quality difference between the two is almost unnoticeable. It'll help you cut down on unnecessary bitrate wastage.
