Does anyone know how OBS bandwithuse is in comparison to xsplit?!
Since iam capped by bandwith and not hardware it would be awesome if it uses less then xsplit.
With XSplit it's very hard to stream in anything better than "veryfast" preset. But people with OC'd mid-grade CPUs are reporting being able to stream at "fast" preset. So OBS will help indirectly in that the slower preset will produce a higher quality picture for the same bitrate if you have a lot of spare CPU.

Friend of mine is trying to use this streamer with an Avermedia capture card.
The problem is that in the decoder it only recognizes 625 lines and prompts for NTSC Pal or SE_CAM, and the result is most definitely not the 1080p he is encoding at.
What gives?

Question: Is it possible to directly input game sources into OBS? Let's say that I want to stream Warcraft 3. I don't want to play Warcraft 3 in windowed mode. Would streaming in fullscreen with warcraft 3 still be fine?

You need evidence both ways of differing CPU usage to say anything like that. They both use x264 to encode, the differences should be marginal at best, IF there are any. As far as i am aware the only difference is in screen capture performance, and until somebody provides solid proof of OBS using less CPU to give the same output (and thus having room to use slower presets) then it should be assumed that they are identical or extremely extremely close in encoding performance, it is very hard to prove either way though unless there is a very significant gap.

Since iam capped by bandwith and not hardware it would be awesome if it uses less then xsplit. It uses whatever bandwidth you want it to use. That's what the bitrate settings are for.
If you are looking for encoding efficiency (quality at the same bitrate) they should be again almost identical

Right now, not yet but Jim is working on a game capture feature for capturing fullscreen games.

I believe there's a beta download on their sourceforge site for direct capture.

Capturing fullscreen games is mostly working at the moment, was going to try to push it out with the next release. However, I had to pause development on it temporarily so I can push out other important features and bugfixes.. I've just been working on fullscreen capture too long and it's preventing me from working on other critical features. So it will unfortunately not be released in the next update, and possibly the one after that. I will however be posting test builds of it when I update it on my site.
It's a very big/complex/difficult plugin to write (you have to literally hook into the target game and capture frames as they come in, then you have to transfer that data cross-process), and I want to make sure it's the best it can be before I fully release it, so it's going to take more time than I originally anticipated. The current pre-release version of it I have posted in the test builds (which you can try out on my website in the "R&D builds" thread) is just too unstable, and is causing games to experience frame lag. It's not at an acceptable state, so I need to spend much more time on it to make sure it is stable and optimized before I fully release it.

ok, thanks for the reply.

Holy crap this is amazing, i went from super laggy on xsplit to no noticeble lag on OBS!! Thank you so much
|
This software is amazing!!!! Beautiful streams with minimal impact.
Currently it crashes my entire system when streaming for some reason though, but I look forward to hopefully more bug fixes in the future that might fix it.

^ could you explain a bit more? I've done extensive testing with FFSplit, Xsplit, and OBS, to try to figure out which was the best for me (i'm running on an athlon ii x3 here, so i find every way possible to improve quality and performance that doesn't require a cpu upgrade, and i can tell you that i can stream 720p on high quality, extreme graphics quality, 60 fps, perfectly fine), and I used to have a ton of problems with all of them. After tons of testing, it turned out I was just using some bad settings, and now I can basically use any of the 3 streaming clients and they all work pretty well for me, with minor differences in each one (OBS has best performance, ffsplit has no reconnect feature so its not worth using at the moment, xsplit is fine).
Are you running on windowed mode (or dxtory if fullscreen)? Try running at a very low bitrate on a very low resolution, just see if you can do it. Get a diagnostic program like hwinfo and make sure you arent maxing out your ram or vram or something silly like that.
I mean.. you sure its an OBS problem, and not a problem on your end? All of the guides and information ive seen out there in regards to streaming are all terrible, generalized, and basic, so i dont think a lot of people really understand what they are doing, and then blame the streaming client. even when obs was not working for me and xsplit and ffsplit worked perfectly, it turned out to just be a major problem on my end, not the software.

I am trying to get UScreenCapture to work with OBS for Brood War, and in my streaming the game itself comes up black when I am streaming my bw games.
|
hm, I can't remember what it was you had to do to make UScreenCapture working, but there was a fix for that I believe (not the most helpful, I know, I just need to write these things down next time). regardless, when my fullscreen capture plugin is complete it will support brood war and older directdraw games as well.
|
Any new updates to OBS coming? 
|
yep, should be a new update tomorrow or the day after -- text output, chroma key, big performance improvements, network fixes, bug fixes, more device support (hopefully). the reason it's been taking so long for an update this time is because I spent a ridiculous amount of time researching and developing game/fullscreen capture. hence why I paused work on that particular feature a few days ago, so I could work on other features. also, been playing borderlands and dota 2, so I've been a bit distracted on top of that as well
|
Nice, what kind of big performance improvements are we talking about, it seems to run better than anything at this current point.
|
Should I even attempt to streaming with this set up?
Q6600
4GB RAM
GTX 260
15Mb down 8Mb up
|
Yeah should be alright. Maybe stick to 480p or so.
|
How overclocked is the q6600?
