With vMix being able to stream to three simultaneous destinations, we have often used it in a setup like this:

Stream 1) Facebook account #1
Stream 2) Facebook account #2
Stream 3) Youtube account #1, primary

However, this turns out to be a very risky approach. If you stop the live stream in Facebook account #1 (in the Facebook web browser interface), this can affect the other streams in vMix, basically making not just Stream 1 fail, but also Stream 2 and Stream 3 in vMix. This means that if a persistent connection failure occurs in either stream, all streams in vMix will be risked.

I have seen this behaviour many times in the latest version of vMix, 20.0.0.30.

As a result, we now send a just a single live stream from each vMix machine to Wowza Streaming Cloud and from there forward the streams to the different CDN's.

Yes restream is a very good alternative being it's basically free with the exception of custom RTMP and transcoding like nowski said. This is my biggest problem with vMix when it comes to their streaming side. Once you start you can't do anything unless you kill the stream. I would love to stream using the tool only and start and stop other streams as I chose. I get around it by sending the feeds out via external and use another system(s) to do this but i'm curious why vmix does this or doesn't allow the option of a more rebust multi-stream solution. :(

It's true! Also serious problem for us. Missing feature...

and also the option of 3 streams with the same encode, if we uses the 3 streams with "use stream 1 quality" and the first uses hardware encoder not work, us vmix uses ffmpeg this is easy to add.

I have contacted the vMix team twice about this, and while I have always been impressed with their responsiveness, this issue doesn't seem to be a priority. At least I haven't heard anything for several weeks now.

Hi,

At the moment all streams in vMix are all linked together by design.
We recommend the following approaches where more flexibility is required:

1. Use the vMix NDI output to another laptop or PC that can be used as an independent encoder for another stream.
This allows full control over the secondary stream using something like vMix Basic HD, or the other free streaming encoders available.

2. Use a rebroadcasting service such as Restream.io
https://restream.io/

This option has the added benefit of reducing the bandwidth requirements of your local connection as the distribution
is handled in the "cloud".

3. Consider streaming to a single provider and embedding that stream into the other social networks you wish to stream to.
For example when using YouTube Live you can embed that into Facebook and Twitter posts directly for example.

Hope this helps,

Regards,

Martin

Thanks Martin, any chance for a separation of the streams in a future release?
