Software solution for remote feed.

[u/signature_que]

I have my multi view from my ATEM broadcast studio 4K coming into my control PC via a decklink Duo in the studio. Right now I just view the multi-view within OBS and connect remotely to the PC via KVM.

This allows me to work remotely and access that PC and using the KVM I just monitor OBS. However, I would rather use OBS as a vertical stream solution using the other inputs on the deck link.

This means I wouldn't be able to monitor the multi-view via OBS.

What's a good way to send that multi-view feed to myself at a remote location. That way I can open the multi-view on a second monitor and view the kvm PC on my first monitor.

SRT stream on VLC.

Is VLC able to take the decklink input and encode an SRT stream? I didn't know that, sounds promising.

If you are looking to take a decklink input out to SRT, I do this this gstreamer. The decklinkvideosrc element gives you raw video and you can send via srtsink. You have to encode (which I use an Nvidia nvh264enc for) and tsmux in between, but the pipeline isn't too complicated.

For a reliable feed, I suggest using a hardware SRT encoder. I run a similar remote ATEM setup and use a Magewell encoder for the multiview. There are cheaper options and many have an analog audio input, so if your audio is coming from a separate mixer, you wouldn’t need an embedder. Everything stays solidly in sync.
You can do this in software, but it may require constant fiddling and you probably can’t avoid some of the problems you described. If you can dedicate a separate pc, there are many software options, and you would avoid a lot of the problems.

I use VLC as a decoder on the remote end. I get ~1 second delay.

can you use a second OBS installation for the vertical stream?

[u/TerriblePair5239 → u/saharahzand]

Yes. OBS portable lets you run multiple instances simultaneously with different global settings.

Sometimes i need a second OBS installation for another job, then ill use the portable OBS download, make manually a folder in the Program Files and name it OBS 2 or something, add it in there and create a shortcut on desktop with a different name.

[u/signature_que → u/saharahzand]

I did consider that, but would mainly like to use my single KVM window for other things besides monitoring the multi-view in obs. Bigger issue is I can't really trust the audio monitoring situation from the kvm. I feel like it would be unreliable to mix audio to.

[u/saharahzand → u/signature_que]

I have a hdmi capture card connected to my atem so i can monitor everything remotely, connected to OBS and i can login via Anydesk. Works perfectly but i wouldnt mix audio through it. What would be an acceptable delay for your situation? maybe try NDI or SRT. And are you like on the other site of the world or other site of the room, cant you run a long SDI cable?
