Question / Help Starting stream, Spiking kb/s, then dropping down to 0 kb/s

Wesleysnopes · Nov 4, 2013

CBR 3000 1920x1080 downscaled to 720p @ 30 fps. (have tried variable bitrates from 800-3500)

What's happening is when I start to stream, the stream connects, then automatically (about 5 seconds after start) I spike at around 3000kb/s, then drop down to around 750, then it jumps from around 750 to 0kb/s.
Dropping around 75% of frames.

Streaming WoW/NES games just to test out my settings, I'm using game capture with aero on (have tried with aero off/window capture same problems)

I'm connecting to Twitch, have tried all nearby servers (westcoast, central and midwest. Even tried eastcoast), refreshed my stream key multiple times.

I've used the log analyzer, only minor problem being SLI, which doesn't seem to be a problem at all.

The stream starts, then drops frames and stops sending data. I stop the stream manually.
Here's the log:

Re: Starting stream, Spiking kb/s, then dropping down to 0 k

Oh, I forgot my up/down speeds.
From testmy (FROM TEXAS):

14 up, 3 down (it was about twice that last night, which I find strange) I feel like this whole problem may be my ISP's fault.

From test my (FROM SAN JOSE) [closest]

Re: Starting stream, Spiking kb/s, then dropping down to 0 k

From what I can see it just seems like typical frame drops. The speed test sites aren't usually a good indicator of stable bitrate. Just because a speed test says you have 3.5 doesn't mean you will be able to sustain that much, usually you can only have a stable bitrate at about 75% at most of the number reported. Often even less, depending on the areas. At what bitrate does this stop occurring?

Re: Starting stream, Spiking kb/s, then dropping down to 0 k

Hey, Jim. Thanks for the response.

I've tested bitrates from 800-3500, but no matter what bitrate I'm running at, when I hit Start Streaming this series of events happens:

It connects to twitch
Starts streaming
The bitrate indicator starts at green at whichever bitrate is set
around 5 seconds later, it immediately drops to red
the stream halts and drops thousands of frames(doesn't disconnect)

I then manually disconnect because it isn't transmitting any watchable data to the twitch servers.

Re: Starting stream, Spiking kb/s, then dropping down to 0 k

Try some different Twitch servers besides the LA one.

Re: Starting stream, Spiking kb/s, then dropping down to 0 k

I'd also recommend running ShaperProbe to see if your traffic is being shaped by your ISP. Cox are known for being... well.. Cox like that.

I'd also advise to manually run the 6MB test on http://testmy.net/upload instead of the 'auto discover' one. You can also run the next step up as well.

Have you tried using JTVPing to see which ingest servers give you the best ping? May have to trial-and-error a few of them to see which will give you good throughput, in the event that it's an ingest or route-based issue.
