TyrionSC2 United States411 Posts January 19 2015 18:53 GMT #2002 So I've been streaming using OBS for awhile for sc2 and dota 2. Lately I've been TOing events for smash and came across a problem - using multiple video sources (capture card, webcam) Every time I try to have multiple video sources OBS freezes up completely. I can't close it and trying to force close it doesn't work either so I end up restarting my computer. I have followed several OBS streaming guides (this one, and Beanwolfs specific to smash streaming guide) but I have not been able to alleviate the issue. I have no idea what's going on. Halp?

uniQkum 5 Posts January 22 2015 01:30 GMT #2004 Hello! Recently I have tried to start streaming and have been mixing around with some settings. However I don't seem to get it quite right. I started streaming with 1920 x 1080, 60 fps, 3500 bitrate. It worked out okay for games like Dota and Hearthstone. However when I played csgo with it my CPU usage is like 90% and you can notice a wierd kind of lag ingame. Not fps drops or latency but more like a input lag. Everytime I turn off the stream I can notice a distinct difference in the flow of the game. My guess would be it is because of the high CPU usage. (?) Then I lowered my resolution and went 720p. 1280 x 720, 30 fps, 2250 bitrate. That delay I was talking about earlier is still there (maybe abit less, but still noticeable enough), and with cs go being such a game where every millisecond counts it is game-breaking. My CPU usage is hovering somewhere around 70 to 90 %. Should I lower the resolution even more? Is 540p the next step? The setup im using currently is; Intel Core i5-4590S @ 3,00 gHz Nvidia GeForce GTX 970 8 gb ram Kingston Fury 100/100 fiber connection. Any help is appriciated!

If CSGO is using high % of many cpu cores, you could use an fps_max at appropriate level; i think you need at least 128 or so (plus 10-20%) depending on the tickrate of the server. Make sure that you're using game capture in OBS always, as well. Alternatively, and probably better if you feel that way, just use NVENC instead of x264. It's not difficult to set up at all (probably more foolproof than x264) and as long as you're not trying to stream at 61+FPS and don't mind the loss of quality per bit compared to good x264 settings it performs great; you should see no added CPU load and if the performance drop isn't imperceptible it should be close. It's especially good on 970/980 which have upgraded NVENC.

ahswtini Northern Ireland22213 Posts January 22 2015 10:52 GMT #2006 btw why not use ultrafast/superfast? it's probably been explained in this thread but I can't find it

Cyro United Kingdom20343 Posts January 22 2015 16:57 GMT #2007 Because they require pretty obscene bitrates for the same quality (like 5-10mbits instead of 2-3mbits) and don't save a lot of CPU. Veryfast -~ slow is approximate actually usable and sane range, with most people defaulting to veryfast and medium being more accessible for actually streamed resolutions if you have decent hardware and know what you are doing

Ej_ 47656 Posts January 28 2015 09:05 GMT #2009 I have kind of a weird question: is it possible to make it so that OBS sources the audio to stream from a window that isn't displayed on "top" of the monitor? I want to able to open StarCraft, start a replay, switch over to web browser/ther program/whatever and have the replay running in background and being streamed. While it can be done, OBS still picks up audio from what I actually hear and from StarCraft. any way to work around it?

ahswtini Northern Ireland22213 Posts January 28 2015 09:27 GMT #2010 For audio stuff you'll probably need soundboard software as OBS just records all audio that you hear

z0rz United States350 Posts January 28 2015 09:47 GMT #2011 Do you have speakers and headphones? The easiest way is probably to set SC2 to play through your speakers and have OBS use your headphone output (or vice versa)

MrCon France29748 Posts February 05 2015 22:59 GMT #2012 I'm using OBS only to record on disk then upload to youtube, anyone knows how to use the youtube x264 recommended options into OBS ? Here are they : Container: .mp4 -No Edit Lists (or you may lose AV sync) -moov atom at the front of the file (Fast Start) Video codec: H.264 -Progressive scan (no interlacing) -2 consecutive B frames -Closed GOP. GOP of half the frame rate. -CABAC -Chroma subsampling: 4:2:0 I guess I need to use the custom option line in the encoder options of OBS but I have no idea what to put there =)

R1CH Netherlands10342 Posts February 06 2015 13:32 GMT #2013 It doesn't matter since youtube will transcode it regardless.

ahswtini Northern Ireland22213 Posts February 20 2015 00:16 GMT #2014 I have a scene set up where I have a bit of teamspeak in the corner on top of everything. After a while if I minimise teamspeak, OBS stops "updating" it until I click on it again. Any idea what's up? I'm using windows capture and compatability mode

Cyro United Kingdom20343 Posts February 20 2015 02:04 GMT #2015 That could be OS behavior just not updating the window when you can't see it

ahswtini Northern Ireland22213 Posts February 20 2015 09:53 GMT #2016 i'm on windows 8.1, are there any settings i could fiddle with?

Cyro United Kingdom20343 Posts February 20 2015 10:27 GMT #2017 Not that i'm aware of, i just keep stuff always up on a second screen

Mackem United Kingdom470 Posts February 27 2015 01:21 GMT #2018 I lost my OBS profile so have to re-do settings, any help would be great. I stream League of Legends / SC2, native res 1080p i5 2500K @ 4.5GHz 16GB RAM GTX 970 13 upload Just wondering what settings to go for?

Cyro United Kingdom20343 Posts February 27 2015 05:09 GMT #2019 ~1080p30 / 720p60 @3500kbit cbr veryfast pretty much same for nvenc
