Question / Help Audio problems and can I even stream at all???

[RobbieRocketpants]

Hi all

I have a horrible upload speed. Maybe 2kbps if I'm lucky, which I know is not conducive to a smooth streaming experience. I have a 25kbps download on a wired connection and using Diablo III as a test on Twitch I have noticed a severe decrease in connection speed to the game when I start to stream which is not helping either. Today I've been testing with Diablo III and the results just seem to get worse. I'll post my log but to summarize - 720p, 1800 bitrate, and generally the experience is pretty nasty. OBS says I'm losing 36% of my frames, up from 22% earlier in the day. Tried switching servers but no good. I wouldn't want to watch my stream :( If I lower the bitrate or res much more I think it's going to look like pixel soup and who'd want to sit through that? Also quite curiously the Twitch analysis told me I wasn't using CBR which is not what OBS is telling me.

On top of that I have another big problem which is audio related and twofold - first, all the audio (game and mic) loops over and over after only a few seconds of streaming. It's not desync it's literally that it keeps looping. Second, my mic only plays in the Left channel. I'm using an XLR mic plugged into a receiver that is then plugged into my computer, I do not have this problem using any other software (Reaper, Audacity, DXTory, you name it). Only OBS plays it out of one channel. And forcing my mic in OBS to go mono has not worked.

In conclusion, am I beating a dead horse here guys? Is my up/down so bad that streaming isn't something I can even do? My provider RCN advertise a 25/4 connection and I get the download okay wired but not the up. I don't know what's going on basically. Thanks.

Just to be clear: you have a 25 Mbit download an 4 Mbit upload. (Not Kb) right?

The looping sounds occur when you watch/listen to your own stream while streaming.... its the same when you put a mic in front of a speaker and it keeps "singing" around.
No clue about the stereo sound issue tho,

 

[RobbieRocketpants]

I have a 25 download but only a 2 up, sometimes 1.5. Very bad basically. I only mentioned 4 up because that's what RCN advertise as the max up for the speed I'm paying for. I think it's odd that I get the 25 down but not the 4 up.

So the looping is fixed by what, simply turning off the sound on my stream while I'm watching it? I watched some of the playback on Twitch of stream tests it had saved and it recorded the looping so I figured it was a problem at my end.

I just tested streaming with XSplit and I do not get the Left channel mic problem that I get in OBS. I really don't know how to fix that.

 

[Greendweller]

Well with those speeds you can not stream at 1080p, Currently you stream at 1800 bitrate witch is more than your internet connection can handle..

follow http://obsproject.com/estimator to get your initial settings correct.but basicly:
Lower the bitrate and resolution.
Ah and yes turning of the sound of the webplayer sould fix it.

No I'm streaming at 720p at a 1800 bitrate, it's still very jerky depending on the connection. Sometimes it's fine but then others it isn't. But if the bitrate gets much lower the stream looks terrible. So that's why I'm wondering if streaming just isn't something I can do.

Btw I do not get the looping anymore after muting the stream, thanks. Still no idea about the mic though.

 

[Greendweller]

The Mic is also a mistery for me and perhaps someone else can help you with that.
But you could try 540p with a 1200 bitrate .
I can't say what preset you could use because i can't see your pc specs in the log.

But yes it won't be a "high quality" stream

 

[RobbieRocketpants]

Seems like the Left channel problem was also being caused by my stream audio being on, I've watched back a few more Twitch tests and it doesn't happen anymore.
