Question / Help FPS Drop & Audio cutoff during streaming

Recently when streaming my games, either fps (Call of duty) or LoL, my frames drop dramatically after 3min or so. When I first dl this program and set the settings to my liking, it never had this problem till now. What is the problem and need solution.

Encoding: CBR checked. Quality [8] Max bitrate [1500] buffer size [2500]
Broadcast: twitch.tv
Video: 1280x720 filter [bilinear (fastest)] FPS [60]

Speedtest: http://www.speedtest.net/result/2728458370.png or

Just all of a sudden it started dropping frames out of nowhere and never did that the first couple of weeks I had OBS. Also my original max bitrate [2500] buffer size [3500] and that never had any problems and it had CBR checked.

Do you think you could post your log? http://obsproject.com/forum/viewtopic.php?f=5&t=97

Also, can you run a speed test at http://testmy.net?

Looks like your upload speeds are having issues and you can't stream at the bit rate you were trying to stream at before anymore.

Re: Frame drop

Weird, your speed test is higher than I expected. Have you tried changing Twitch servers or lowering your bit rate?

I was originally in US West San Francisco (closest server to me) and was fine at first. Recently been getting those dropped frames from 60fps to way below 20. I changed it to US West Los Angeles and still frame drop. I also lowered the bitrate and still frame drop.

Re: FPS Drop during streaming

You dropped no frames with LA secondary on lower bitrates. but you're lagging some, try running the 64 bit test build if possible and stick with the LA secondary server since you dropped no frames with that. try 3066 bitrate/bufsize

Elgato does not work for the 64bit. The real problem is not the frames drop but the FPS drop from 60fps to below 20 fps

Re: FPS Drop during streaming

Your frame times are too close for comfort to the ~16ms limit that 60fps needs to stream with no lagged frames. My guess is that you're lagging frames on that edge.

One thing you can try to help improve your frame render time would be to remove the downscale and change your base resolution in OBS to 720p. Right now, you're capturing at 720p60, then upscaling it to 1080p to fit the base resolution, then downscaling it again to render it in 720p. That's a lot of unnecessary processing...just set the base resolution to 720p and be done with it.

Even then, I'd think a i7 3770k could do 720p60 just fine, especially when not running the game. Is it overclocked at all?

Finally, your latest log still shows you dropping a lot of frames in addition to lagging frames. I still don't understand why that is, assuming your speed test is accurate. Are you streaming over wireless, or sharing your internet line with someone else who is using a lot of bandwidth, or running things like torrents at the same time?

EDIT: Also, I see you're using the "sync audio and video time" setting in Advanced, which is probably what is causing your audio to shut off. It's kind of an experimental fix, so I would recommend disabling that.

EDIT 2: I just watched the video...YouTube is not the best place to show frame drops on a 60fps video since YouTube re-encodes to 30fps. Also, I understand you're frustrated, but your attitude on your video isn't exactly inviting of help.

I will downscale it to 1280x720. This custom built pc is wired and the router does share the internet to other sources but the other sources does not require a whole lot of bandwidth. Its weird how when I first dl OBS about near month ago all these settings were the same and nothing changed. This past week is when I see FPS drop and audio problems. I built this PC specifically for gaming/streaming/editing

Re: FPS Drop during streaming

I watched some more of your stream tonight, and it's clear you're still getting a lot of packet loss. Can you run ShaperProbe and post the results here? http://www.cc.gatech.edu/~partha/diffpr ... probe.html

Also be sure to turn off the Force Audio and Video sync thing, because I'm pretty sure that's why your audio keeps breaking.

sorry about the video on youtube...just real fustrated because these issues occured out of nowhere. Can you join my stream and monitor it so far. Currently streaming pc games causes no FPS drops while playing Planetside 2 and LoL. Now I will see about the elgato gaming capture hd with my xbox

Also with the FPS dropping during the stream, does anybody know the problem with my audio not streaming? It cuts off during the stream randomly and this is one of the awkward warnings I get in my logs, Warning -- MMDeviceAudioSource::GetBuffer: GetNextPacketSize failed, result = 88890004
