This is a life-saver! My computer is running out of USB bandwidth with all my capture cards, and with this I can hook everything up and have it working until I get more USB-controllers. I am a hardware-kind of guy to the core, but this works flawlessly and I'm actually second guessing some stuff...
I suppose with a deticated, closed-off Network switch and some extra ethernet cards you could do some truely amazing things with this, plus save a good couple of bucks on capture cards for each of your other PC's.
This is nothing short of amazing, I'm even using the official 20$ NDI app from AppleStore to connect my Iphone to this and I only see possibilities with this technology. To the best of my knowledge the limitations will be within your home network.
Works really well except for the fact that the provided NDI Redist Exe file you are given a link to is a download that flags as malware, the download originates from rackcdn.com which with a quick google shows heaps of malware/trojan warnings.
With every version update, this keeps getting better. 4.2.3 (current) is the most stable so far. This plugin expands the usability of OBS to a whole new level. We use this on a regular basis at the production company I work at. Thanks again, Palakis!
This plug-in is super easy to setup and use and having NDI support in OBS to get around clunky capture card setups for two PC streaming is fantastic.
However, I've had major issues with being unable to hold consistent 60fps via NDI, even with machines well beyond what's required and a solid gigabit network. My main PC also has to be frequently restarted because after every stream, game audio goes out of sync when using the NDI plug-in. The only way to fix it is to restart.
While I do appreciate this is a free plug-in being made by a hobbyist, support for this is also virtually non-existent (though in keeping with the general OBS support experience.) The author only responds to a handful of support threads and if you have any problems with this at all, expect to be left to figure it out yourself.
I still use this plug-in (especially since the alternative is XSplit which just, no) but it still needs a lot of refinement.
This plugin has solved such a major headache for me and allowed me to get my Twitch.TV stream back up and running. With NewTek NDI, and this plugin, now I can output my 15Mbps stream to restream.io while simultaneously sending my output stream at full quality (~200Mbps) to my other broadcasting OBS machine as an NDI Input, from there I send to Twitch at 6Mbps. Before my stream was being blocked as the bitrate was too high and I didn't want to pay for Transcode time on Restream,IO anymore; this enables me to perform my own "transcoding" with NO extra cost. Setup is super simple and I was ready and streaming on both boxes within minutes. The CPU overhead is minimal on my main box, like 4% extra, so it doesn't effect my gameplay or other material really much at all (i7 960 @ 4.2Ghz). Even with the much extra IP traffic, there's no encoding to network lag on either OBS session on either machine, so no dropped frames due to render lag or network lag! Simply amazing! I do wish that there was finer controls for the encoding in terms of bitrate, but at this point... I'll take it! Great job!
