General use case would be for the ever so common twitch streaming using NDI to send the footage from my main computer to the Raspberry Pi for encoding and sending to twich or any kind of streaming service.
Tuna Member. Pretty sure that no. The software is not ported for ARM. And if it was - there is no support for OMX hardware encoder afaik.
A strict collaboration with the raspberry foundation to bring OMX optimization in the code, could help raspberry foundation to spread PIs to the gamers nation, and OBS to make a "streaming brick" at a really low price :D. Filip S Member. This would be a dream also with ndi :. I got CMake to build all of the necessary configurations. There were a lot of dependencies I needed to get installed.
I went through the missing items one by one in the output from CMake, and eventually got it to recognize all of the requirements. When I attempt to run sudo make -j4 it errors out.
The errors appear to be related to ffmpeg-mux, although it seems like all of the ffmpeg dependencies are in place. I checked a bunch of the specs before I started this, and I thought the RPi4 met the necessary requirements, but I guess not. Does anyone have a recommendation for a similar low end computer that OBS will actually run on?
Michael Graves Member. Filip S said:. Use the Pi as a VPN host openvpn over Docker could be the best and fast option and connect the pc and the server to that network. Any alternatives like ndi but free opensource? The rpi3 was to slow to read via usb2 but it tried to read - it looks like rp4 dont even care to try ; Just for fun I also tried the elgato connected to the usb2 on rpi and it reads more showing v4l2-ctl -D Driver Info: Driver name : uvcvideo Card type : Cam Link: Cam Link Bus info : usb Last edited: Sep 21, Is UVC mode?
Avermedia GC and GC working. Because I do not know this device elgato camlinkI asked in what mode it works, one of the possibilities is UVC. Avermedia Live Gamer Portable only works with Windows drivers, cannot run on Linux, recent generations use standard UVC drivers, so you can get the image.
And what the lsusb command shows and what is in dmesg after connecting elgato. Cooling fan - you need. Flyrain New Member.Forums New posts Search forums.

And all the clear problem with the omx encoder, you checked on the software encoder? Not yet. I try after work. With software encoder it works, but Last edited: Sep 24, Filip S Member.

Live Production Software Forums www. Welcome Guest! NDI Video Distribution. Right now we're running composite video to oldschool Tube TVs over RG6 with a few line amps here and there.
Yes, it's hideous. We already have Ethernet distributed throughout the church and I was thinking of feeding an NDI stream over a dedicated portion of the network to each TV on the campus. This would be a lot cheaper than the BirdDog option. Does Vmix require the full "supported hardware specs" to do a simple NDI viewer?
Hi first you have to understand that NDI is not a distribution oriented technology.
For 3 main reasons: - it requires huge amount of bandwidth - it requires quite high spec devices to decode - it requires quite high spec device to encode Hence it is the most expensive way to distribute video over a network.
Just to make it clear, 1 NDI stream requires from 60 to Mbits of bandwidth depending on the resolution. A gigabit network interface the one from your origin server for distribution can only transport from 7 to 15 streams, so 7 to 15 screens.
And then your network capacity is close to the max or already overloaded. Doing the same thing with an appropriate technology like UDP Multicast would consume only Mbits for up to screens! Hi Guillaume, thanks for the reply! I should have mentioned that I'm completely new to the video world.
I ran into the vMix booth at NAB just a few weeks ago and was super excited by its capabilities. Upgrading our video distribution came as an afterthought. Do you have any UDP Multicast solutions you would recommend? That makes a lot more sense to me - I'm just having trouble finding the right solution.
I have come across several google hits referencing VLC. Is that the software you'd recommend? Does vMix have that capability built-in?raspberrypi servo iphone camera NDI

Live Production Software Forums www. Welcome Guest! Inexpensive diy method of hdmi to ndi. Good day all, I'm personally looking at an inexpensive way to get the fruits of ndi in my small studio without the big expenses.
There's a few great but expensive options coming out but hey, I'm sure with the tech that's around, we can figure out a way to d. I've been looking at the raspberry pi board with an hdmi capture attachment but I'm just not too sure if this is the way to go. Love to hear your input! Cheers, Frank. That can run Windows and the basic edition of vMix. Costs add up. If you have to buy everything new, before you know it you're close to the cost of a BirdDog device.
Hello, Hdmi to NDI? The spark appears to be the cost efficient way for the moment. Until NDI Cameras are common they seem they will be expensive cameras. You do get wifi on a spark, if you are game to use a wifi uplink. I can see many times where I would use it and many times where I would not. Good for auxiliary cameras, but maybe not your main cameras. Factor in the price of the capture card you are now NOT buying for that camera.
The price point of the spark is just at the point where I think it's not worth the hassle to make a home brew NDI capture machine unless you have a really efficient way of making one.
Think of it as a low-latency, high-quality way to deploy a facility wide-stream. The PI already has the necessary hardware, just a matter of software. Thanks for the input all. I will continue to add to this thread as I discover more about this.
Just needs to be x86 based hardware. Linux is supported so Windows Licencing wouldn't be an issue. Works very well. One system has been running for days straight. The trick is to find well priced capture hardware for hdmi.
I actually think that this may be a marvelous solution. You could do it with mjpeg too, to have some sort of ip video if you want. It's not as realtime and high quality as NDI, but very affordable.
Thanks guys for the input. I did find this capture card too, which is uber cheap but a review does say it works with obs.

A p60 NDI stream requires at most around mbps. This is an application that can pick the stream off the network and display it on a monitor. It has some nice features, like the ability to overlay a second stream picture-in-picture and show audio metering.
I used this approach at Clueconwith a very small PC purchased just for the task pictured above. In BirdDog. They have recently been extended to decode as well. No requirement for a Windows PC.

All the reliability and convenience of an appliance. BirdDog are first to market for one, very good reason. They developed their own firmware to deal with NDI. Their products are FPGA-based, allowing them to be effectively reprogrammed in the field. Newtek support for partners included an emphasis on such a hardware strategy. At least in as far as the NDI decode function is concerned.
That makes sense given their support with sample code for FPGA developers. Why does this matter? The price of the N2H is not yet known.
Most especially in long term, fixed installations. At that price I would buy it over the small Windows PCs for an upcoming project. DeltaCast reports that the N2H is very conveniently powered via standard power-over-Ethernet.

This would replace the HDMI. Active Oldest Votes. There's no way to do this without using an external converter.
This isn't an answer, but I had no choice since my reputation isn't high enough to comment. The elephant in the room is that HDMI does not support closed captions. So an external device is too late. Maybe the Pi is unable to be the device we are looking for, but hopefully there is some device somewhere that lets us break into the Video Bus pre HDMI to convert to SDI as well as extract and embed the caption data.
