It would be great to be able to define the number of streams in vMix yourself.

One way to go about this could be to start with a single stream available, then the user clicks + to add the number of streams he needs.

Unless there is a hard limit in ffmpeg or the ffmpeg implementaion makes this impossible, this would be a great improvement.

This is especially true for those on systems using Quadro P2000 or above, with unlimited hardware encoding sessions.

One would argue that allowing the user to add an unlimited number of streams, could potentially cause a stressed system an in turn cause instability. However, some sort of user judgment is already needed in terms of how many inputs you add, etc. before the system is pushed too much.

Others would point to the fact that services like restream.io and similar should handle multiple streams. This is true in some cases, but in other cases, with the system resources and bandwidth available, one might prefer to stream directly to the CDN's.

What do you think?

Just use external output to feed FFMPEG externally and you can do anything you want either on the same host or even remotely via NDI.

vMix is not supposed to do everything by itself, I much prefer it only does what it does well. If you need more, just use what it provides to design a workflow that reaches your goals. You will never find a hardware device or even a software with no limits, the point is to take advantage of its features and reliability to add what you need externally.

Independent streams which was introduced in vMix 21, could also have been achieved with an external workflow.

The stream design however was changed on request from us and likely others too.

With your attitude it probably wouldn't have happened and a feature request forum would be obsolete.

Although you say that "vMix is not supposed to do everything by itself" it is being marketed as a complete solution - and many users use it as such. I do agree that sometimes it makes sense to separate things in a production. Last week a did a production where camera switching was done on a dedicated video switch, the audio was supplied from a dedicated sound mixer, the external stream feed were supplied from another machine and the streaming was done on two dedicated encoders provided with an external feed from vMix.

However, at other times, streaming from vMix can be incredible useful. And if you need four streams and not three as currently provided, this feature request would make that easier.

Which is why you are going to +1 it ;-)
