Question / Help Live stream freezes

simpel

New Member
Hi!

I'm trying to live stream to Facebook but the stream freezes and my computer is getting really slow. I'm guessing there is something wrong with my settings because my internet speed is high and my mac is pretty new. Here's all my settings, what could/should I do to optimize speed? I'm specifically wondering which encoder is best to use and what's the optimal bitrate, CPU Usage Preset et. al. for a computer like mine?

For some reason the file upload didn't work here but my OBS Log file is here: https://www.dropbox.com/s/xbxpfn1ogu63krm/2017-06-21 09-43-49.txt?dl=0

Is that logfile from a stream attempt that failed? According to the logfile, it was stopped manually after a couple of minutes.

That said, the log is indicating your problem:

10:05:25.166: Output 'adv_stream': Number of skipped frames due to encoding lag: 15903 (95.0%)
10:05:25.166: Output 'adv_stream': Number of lagged frames due to rendering lag/stalls: 7503 (44.5%)

The computer is failing to render 95% of the frames in the scene because it can't encode them.

What's the video source in the scene-- just the built-in camera?

Although it's not on, your "Rescale Output" resolution in the output streaming page is wrong. It says 1080x720. If anything, it should be either 1920x1080 (1080p) or 1280x720 (720p). I doubt this is the problem, though.

Hi, yes I played around with two cameras, the built in one and a logitech 1080p webcam. The stream didn't fail per se, it just lagged enormously...

Which encoder would you recommend using?

x264.

Try the ultrafast CPU preset and see if it still lags.

You also asked what settings would be appropriate for your computer, but never gave specs.
