Question / Help 480p and 720p stream at the same time on twitch?

[orbo]

I started streaming a month ago. I get an average of 15 viewers at one time. Some people complain about buffering which there is nothing I can do when I am not partnered. I had an idea though. What if I stream at 720p30p 2000kbps AND 480p30p 900kbps? I would accomplish this by using obs original and obs multiplatform.

Obs original will be the 720p stream. My stream will run normally here. The fun part is how I would do the 480p part. None of this has been tested. I do not know if two instanced of obs original will run at the same time. I am assuming it will not. This is all in my head and being tested tonight after some feedback here.

My 480p stream will be set up in obs multiplatform. I will be using a separate account for twitch alerts and twitch to stream it. Both streams will be from the same computer. I would like feedback if you think my computer will be able to handle this. I will be capturing the 720p stream though window capture feature. Having the game audio outputed to desktop so both programs have equal access to it. Then setting my mic up in both programs (It is a blue yeti. I am assuming it will work). That gives me the picture, mic, and game audio used for the 720p stream on the 480p stream.

Now to my hardware. I stream mostly wii u games so I capture with a yuan dvi pcie capture card. No pc games will be streamed this way.

Pc specs:

I7 5820k @4.2ghz
Gtx 970
Msi gaming 7
2x 500gb evo 850 sad
3tb wd black hdd
Cosiar rm800 power supply
Windows 10

Internet speed is 70 down 10 up

Any opinions? I emailed twitch support and they said it was fine as long as my hardware can handle it.

Considering you are going with reasonable 30fps your cpu should handle that easily, at worst you could always use quicksync or nvenc for the "shitty" stream. Take note that gamecapture can not be used twice but you could just capture the second obs via window capture. Obs1 can be started twice with -multi behind the target line of your shortcut so as example ""c:/program files(x84)/obs/obs.exe" -multi"
I _think_ the same works for multiplatform but im not sure if it was put in yet.

edit: i overlooked the wii u part, ignore the gamecapture stuff i wrote. also http://jp9000.github.io/OBS/general/shortcut.html

Thank you for the reply. I am glad I do not have to use multiplatform :). I will try this tonight. I have never seen someone do this and I hope it works. It will be a little more mobile friendly without me having to make my stream complete shit for desktop users! Just glad my computer should be able to handle it.

I run two instances of OBS at the same time and it works with the -multi switch. I also use a -portable switch so each OBS install saves its own settings separately. You can use the 32 bit and the 64 bit installs for it, or you can copy the OBS files to another folder and run the copy as your second OBS instance.

You will need two Twitch channels this way, right? If your viewers buffer out at 2000kb/s, that's pretty bad. Its not really your fault at that point.

Yeah, I would need two channels. I am assuming they are using mobile or wifi. 2000kbps is nothing in todays world but I want to try and accommodate people. Got to hope I can get partnered someday. Thank you for the information!
