Question / Help Duplicate Frames from Specific Source

Hey guys, I am having a problem with OBS that I cannot figure out.

My main PC is using a 4770k and gtx 670 on my gaming PC and streaming to my secondary PC.

My secondary PC (8350fx and gtx 560) has a Virtualization of Ubuntu which is running Ngin-x with the rtmp module. I then run OBS from windows on the secondary PC and use the obs plugin to grab the video from the rtmp server and stream it to twitch.tv.

I am currently forced to use xsplit on my main PC to stream to my RTMP server because whenever I use a window capture on OBS I get duplicate frames galore. Anywhere between 10-20%. I narrowed it down to window capture because whenever I use any other sources it is fine but as soon as I add in any window sources I begin to get the duplicate frames. This happens at all encoding presets as well ranging from ultrafast to medium. Clearly the 4770k should not have problems keeping up with a 720p stream on the very fast preset.

I would prefer to use OBS on both PC's in order to stream. If I use xsplit to stream to my rtmp server I cannot go over a 14,000 bitrate. This forces me to do the downscaling on the primary PC instead of sending it to my secondary PC. Ideally I would like to stream at 1080p/60fps with quicksync or nvenc at an extremely high bitrate for lossless quality to my RTMP server then have the second PC do the downscaling to 720p and stream to twitch at about 3000 bit.

Anyways I kind of went off topic, I just need to figure out why window capture is giving me duplicate frames.

I am also using windows 8 and obs 0.60b in case you are curious.

If possible, post a log of this particular problem (unless I'm misreading what's going on)

I know both streams are very short but these are from my short tests to isolate the problem. If I let the stream go for 5 minutes or 1 hour the amount of frames duplicated remain approximately the same.

I would love to use OBS to stream to my RTMP server again but 10%+ frame duplication is unacceptable and makes the stream frame rate look very inconsistent.

**edit**

I should also note that it's not a specific window capture, if I use one or the other the duplicate frame % is cut half so either window capture is causing OBS to duplicate frames.

Also I tried completely removing the sources and re-adding them and still ended up with the same results. I use chroma keys with both sources as well. I tried just running the window captures without applying the chroma key to see if that was causing the issue but it had no affect on the amount of duplicated frames.

You're using 50000 bitrate with 3000 buffer. I haven't tried anything like that personally, but it sounds really really bad. Try 25000/25000, then tweak from there. If 25000/25000 has the same problem, do it anyways for at least five minutes and post the log file.

It happens no matter what bitrate I use. The bitrate isn't the issue otherwise the duplicate frames would happen all the time.

Humor me and do what I suggested anyways. Its part of the troubleshooting process. Otherwise I'll have no further suggestions.

It seems like there's graphics card stalls. I think this could be related to the fact that you have two different video cards in your computer. It's not the first time it's happened in that particular case. It may depend on what's on what monitor when you're capturing, I'm not entirely sure unfortunately. Try out "compatibility mode" in window capture as well, and see if it makes any difference. Otherwise, not entirely sure, but I am eyeing those two different adapters.

Digging this up and have to say nope, I have the same issue right now when I use Window Capture while trying to record Elsword (Game Capture doesn't work.)
Both of my Monitors are connected to the same GPU. (The Game Capture duplications are gone it seems)
Still get Duplicated frames in Window Capture.
Well its not 10-20% but above 5%
