Please give us more details...

3 streams? on different platforms?

2 audio channels? Yes it's doable... more or less easily depending on your answer to my 1st question...

I explain how to use the EXTERNAL output to send your PGM to another encoder on the same PC

You'll need a powerful PC (depending on your streaming's resolution)

For the audio part, there are many solutions. I'd like to have more details on this.
Will your audio only contain the german or italian voice? Do you have other sounds to mix?

it also depends on what equipment you are using? Where do(es) the sound(s) come from? Do you have an audio guy with a pro mixer? Do you have a multi-entry soundcard? Do you use a virtual sound device like virtualcable for example?

Please explain the audio part of your project...

It depends on the nature of the entire audio production. How many audio sources have to be mixed? Do you have sounds coming from the venue via cameras or other mikes, do you have sounds coming from video files or simply 2 speakers each of them having a mike ?

The number and origin of audio inputs and sources to be mixed is the first question...

Then the number of separate inputs/outputs in the soundcard is the second one...

After that,it's possible to consider many ways of routing things to the right encoder

The minimum requirement is to have an audio soundcard with 2 inputs and 2 outputs

German on input1/output1 sent to vMix input
Italian on input2/output2 sent to another encoder input

You can then stream german audio with images on YT1 via vMix/FFMPEG normally

Activate the EXTERNAL output and launch FMLE for example
In FMLE select vMix Video and the audio output2 from your soundcard
You can then stream italian audio with images on YT2 via FMLE normally

But using this method you can't have other audio source coming from vMix in FMLE streaming

For more complex projects, the key is to use something like VB audio cable or Virtual Audio Cable (donationware).
http://vb-audio.pagesper...range.fr/Cable/index.htm
http://software.muzychenko.net/eng/vac.htm

Then to configure vMix audio buses A & B using these software audio cables.

Hope this helps

2 different audio inputs for the 2 speakers and 1 background audio from camera

My idea:
Speaker 1 Audio Channel A
Speaker 2 Audio Channel B
Background Audio Channel A+B

Stream 1 with Audio Channel A
Stream 2 with Audio Channel B

My question i can set de different audio channels to the 2 streams?

I see 2 simple solutions depending on your equipments

Solution 1
with an external audio console (if you can de-embed audio from your camera)
Speaker 1 Audio Channel A
Speaker 2 Audio Channel B
Background Audio Channel C

mixing console output 1 for A + C > going to soundcard entry 1
mixing console output 2 for B + C > going to soundcard entry 2
(if you don't have AUX outputs, you can use main stereo output as 2 separate mono outputs)

the rest is same workflow as described before: soundcard 1 goes to vMix, soundcard 2 goes to FMLE

This can also be achieved without console with a good soundcard with at least 3 inputs and 2 outputs

Solution 2
With a 2 buses audio card (or 2 audio cards) + a virtual cable or virtual mixer solution (as described before)
Speaker 1 input/output 1 sent to vMix
Speaker 2 input/output 2 sent to vMix
Background Audio embedded in camera input

In vMix :
you configure Bus A (or B= as an output with virtual cable
Audio input 1 is set to MASTER
Audio input 2 is set to Bus A (or B) AND NOT TO MASTER
Background Audio is set to both MASTER AND Bus A (or B)

You can stream german + background to YT1 with vMix (italian won't be included in MASTER)

You activate EXTERNAL for 2nd encoder, FMLE for example

in FMLE you select vMix Video and Virtual Audio Cable (the one you sent Bus A to)
You can stream italian + background to YT2 with FMLE (german won't be included)

Have fun!

So i add 2 audio inputs in vmix once per mic atached on the mixer

And the camera mic over sdi

this console is ok.

The easiest way is to output your audio from the camera to your console with a SDI de-embedder or simply by connecting your camera audio out. Solution 1

You need 2 encoders (vMix + another one). This setup is CPU intensive. Make sure your PC supports it.

So here the complete setup i mean:

Speaker 1 > Channel 1 on Mixer > Vmix audio Source 1 (Channel A)
Speaker 2 > Channel 2 on Mixer > Vmix audio Source 2 (Channel B)
Background Sdi Camera > Video Input 1 on Vmix (Channel A and B)


Stream 1 to YT 1 Settings in Stream Quality settings Audio channel A
Stream 2 to YT 2 Settings in Stream Quality (Different preset as stream 1) setting Audio channel B

I hope so works

Stream Quality is 720p

Workstation:
Intel i5
16GB Ram
Nvidia Gpu
Blackmagic sdi input

With this machine i have allready made 3 streams to different destinations

I don't think you can do it with an i5.

I don't think you can do it the way you expect.

Try and you'll see...

Hello, everybody!
I have the same problem and I foud a little solution:
1. Technics: 2 PC (Asus ROG), 2 audio interfaces that connected with PC
2. First PC streamed 2 audios. First audio I stream from vMix, for second I use "external" to OBS program.
3. Second PC I connect with using NDI with first PC. And stream using vMix.

Now I have a new problem)
I need to add 2 more voices.
It will be cool if vMix can stream one video with different voices at one time at different rtmp-streams)

Or someone know how to solve this problem?
