Question / Help Twitch Video Freezing/Requires Video Set As Source

[OnTheFrontLine]

For the last few weeks, my twitch stream has been having an issue with the video freezing, yet audio never skips a beat. I believe it is happening on both desktop and mobile. If you are on mobile you can hit the little gear icon and change the video setting to "Source" instead of "Auto" and it will stream flawlessly.

Last night i tried a full reinstall of OBS, even deleting all application folders and set the entire thing up from scratch again, yet the problem persists. All of the settings i have are set to the twitch requirements as outlined in the red text that tells you what to change and automatically optimize.

I have it set to 3500kbps, 1920x1080, no downscaling, and using NVENC as the encoder. I have an EVGA 760. The twitch dashboard shows the stream quality as excellent. Also im not sure if there is a correlation between using the 32 or 64 bit version. Im currently running on 64bit windows 8.

If you need log files let me know where to find them and i will post those as well.

Any help would be greatly appreciated :-)

Okay i just did the log analyzer and it shows zero issues with the log. Also i would like to add that i tried the x264 instead of NVENC and it didnt seem to make a difference.

Go ahead and post the log here.

Does the Twitch buffering icon show up when you're watching the stream? Does the VOD afterward have the same problems?

Thanks for the reply :-) Log file below. The buffering icon never shows up in my testing and the VOD/Recordings are perfectly fine so it is delivering as it is expected.

As far as the log file below goes i do see one minor in the log analyzer in regards to the llhq preset, but i have tried changing it to every other thing on there and it doesnt seem to make a difference.

Even if your internet is great, Twitch just doesn't give us lesser-known streamers the bandwidth for 3500kbsp.
Try streaming 720p (either as base or by downscaling), 30fps, 2000kbps.

The log is incomplete, but if the VODs are fine, then the issue is with Twitch delivering the video to you, and you not being able to download it fast enough. It doesn't happen to everyone watching your stream. If you're concerned about it, you can try streaming to a different server or lowering your bit rate to see if that helps at all. But it's not an issue affecting everyone watching your stream.

We'll I changed to 720p downscale/60fps/2500kbps and it seems to have cleared up the problem. I may play around with some settings but for now it is working! I actually ended up finding a super nice guide for OBS on the twitch website. Not sure how I missed it before. Thanks again for your help :-)
