Question / Help Multiple Audio Sources Setup

[mrroper]

Hi Everyone,

I have recently set up a Local RTMP server (Red 5) that allows me to stream from my gaming PC using NVENC to a local stream server using a high Bitrate / Resolution (2560 x 1440)

I then use RTMPDUMP to feed this stream into VLC so I can window capture this on a seperate instance of OBS on the stream server PC.

VLC is then output to a separate playback device so I don't get that sound coming through the speakers of the streaming server. (I use this PC for TS and other comms)

How can I feed these sources into OBS? so that stream watchers receive both audio channels? I have tried to use the Stereo mix Recording Device as the audio source in OBS but I get an echo on this channel and I cant work out what is causing this echo!

I am so close to being able to effectively game in 2560 x1440 and stream without ANY performance hit at a high quality but this last hurdle is stopping me :( any ideas guys?

Ok which sources exactly do you want to include into OBS? VLC player outputs to one device, so you can select that as desktop audio I would think and use the microphone for other stuff. I am not sure what you mean by both audio channels. So if you could explain that :)

About the setup, do you need rtmpdump to grab the stream off the red5 server? I used vlc alone with nginx a bit and in the current vlc version it sometimes works good, sometimes not that good, but I never had luck with rtmpdump at all!

Hi Jack0r,

I have sorted the sound issues now thanks :) I ended up running a audio cable from my speaker out and back into my Line IN. This then allowed me to use the DirectPlay Audio plugin to include the LineIn as an OBS source.

Regarding the use of RTMPDUMP I have found that I get lots of stutter from VLC directly (this could be a consequence of using Red5) but I dont have an unix image to put NGINX on at the moment to test another RTMP server.

What I found with RTMPDUMP is that I need to start the Game stream first with no output, then run RTMPDUMP piped to VLC. I can then start capturing the game using a hot key. If I don't do this VLC wont load the stream :S strange but its workable at the moment and means I can play at 2560x1440 and stream via NVENC to my "streaming" pc!

Cheers
