Question / Help Losing frames randomly during stream

[roshmaster]

I upgraded my internet and I get around 3.1 mbit upload speed. I think that the dropped frames are from spikes in the internet but I am not sure. I've tried tweaking the bitrate to 1000 and it doesn't seem to help. I can't for the life of me figure out how to get the stream to stop dropping frames randomly. Here is my log:

Try running a little tool called shaperprobe and post the log/results from it. Also try using game capture/window capture with aero ON instead of monitor capture if you don't really have to capture the whole monitor and change the preset back to veryfast.

 

[roshmaster]

I'm not sure why the log says I am set to "ultrafast" because I looked at the advanced option and I have it set to veryfast. Perhaps I pasted a log that was run before I made the changes back to default after tweaking a bunch. I re-tested under the veryfast setting and am getting the same results.

I downloaded shaperprobe and this is the results I got:

DiffProbe release. January 2012. Build 1008.
Shaper Detection Module.

Connected to server 217.163.1.100.

Estimating capacity:
Upstream: 3383 Kbps.
Downstream: 4513 Kbps.

The measurement will take upto 2.5 minutes. Please wait.

Checking for traffic shapers:

Upstream: No shaper detected.
Median received rate: 3285 Kbps.

Downstream: Burst size: 51-226 KB;
Shaping rate: 3920 Kbps.

Run a 6MB test at http://testmy.net/upload to get a better idea of your actual throughput. Speedtest tests based on dead-file transfers, while livestreaming relies on constant throughput. Many ISPs rely on 'burst mode', where your transfers run well below your rated speed for the most part, but will briefly SPIKE far above your rated. Streaming cannot use these spikes.

If you are DROPPING frames, the issue is with your network; either bitrate set too high (most likely, as people expect their speedtest results to be accurate, and aren't), poor line quality/packet loss issues, or an issue with the receiving Twitch server.
If you are LAGGING frames, that issue is on your local system. You appear to be doing both.

Do not take TestMy.net's results at face value though; whereas it is more accurate for the purposes of streaming I have proven that TestMy.net has equally many issues as SpeedTest. Take its result and interpret it, do not take it too literal.
