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.NDI delivers high quality video at very low latency, under one frame of video. 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.

Thanks for the hint. I wrote him. I dont care if it is not 60fps, as long as it works If Thomas has it working for Linux there is a good chance you can get it working. I will not be updating for NDI Version 3 for a little while yet. Meanwhile it should build OK.

Leave out the resource files and the ofxNDIdialog files, and do not use async sending until I can investigate the problem. I had a brief look at your repository and I think the changes should work on Windows OK. I am looking at NDI Version 3 now. Meanwhile the version 3 dlls should be back compatible with version 2 code. I will not commit any code for a while yet, but will incorporate your changes.

The Version 3 update will exclude "ofxNDIdialog. Thanks for the work!

Sermon on change from the inside out

Looking forward for the linux version! Still dont know how to compile openframeworks stuff without provided make files :. Just figured out that we have to wait to get a version running on RPi since the codec is not Arm compatible yet I started converting to Version 3 and it isn't as straightforward as I had hoped.

Meanwhile the existing code should still work OK.

After some delay I have made changes necessary for Version 3. There are some changes to argument types to meet with Version 3 rather than casting from those for Version 2. Also RGBA format has a bug which is fixed with a patch but does not appear to be in the release version yet. Meanwhile BGRA is just as fast.

The receiver code is commented to explain it. It would be good if this was tested for OSX before I commit the changes. When you have time, could you email me and I will send the code.

I revive this thread, trying to compile example-sender on the Raspberry Pi 3. The NDI library seems to link as expected, but the compilation fails:. Is there a package to install on the RPi that would solve these dependancies? You can exclude these lines and it will still compile, so try that first.An Openframeworks addon to allow sending and receiving images over a network using the NewTek Network Device Protocol.

Search source for "Vers 3" Note changes to function argument variable types to match with Version 3. With update to NDI 4.

Experimental audio functions are included but not tested. There are options to send and receive using ofFbo, ofTexture, ofPixels as well as an unsigned char pixel buffer. If receiving to ofFbo, ofTexture of ofPixels, it is not necessary to manage sender size change from the application. Nor is it necessary to handle receiver creation. Simply use the receive functions alone. For best efficiency, the sender class includes pbo pixel buffer readback, activated by SetReadback. Refer to the header files for details.

Examples have been updated to include all the options available. For a simple, practical example, refer to the webcam sender. The examples assume Openframeworks 10 and are not compatible with previous versions.

Sender size update and receiving buffer size change have to be manged from the application. The OF Project Generator will create your project with correct paths. After installation, a license document is available for review from the root of the SDK folder. If the dlls are not included with the application, the user should install the NDI runtime.

NDI 3. NDI 4.

NDI-to-HDMI on the cheap?

NDI carries video, multichannel uncompressed audio [ citation needed ] and metadata. Metadata messages can be sent in both directions allowing the sender and receiver to message one another over the connection with arbitrary metadata in XML form. NDI also allows senders to determine the number of connected receivers, so they can skip unnecessary processing and network bandwidth utilisation when there are no NDI receiver clients connected.

NDI Receivers can opt to connect to various combinations of streams, to support things like audio-only or metadata-only connections where video is not required. There are clear differences in the technology used by these protocols.

Multicast Networks for Live Streaming - NDI HX Driver Update

NDI devices from other vendors followed during In order to quickly bring these products into the NDI space, NewTek created a new driver to replace the existing AirSend driver, which could be installed on these existing AirSend compatible devices, instantly converting them to NDI compatible devices with no change required by the original CG vendors.

Version 3. This removes the latency requirements that are inherent with TCP connections. NDI HX uses a lower data rate making it easier to use in bandwidth-limited connections.

NDI is also used within cloud-based production systems, [38] with its compressed video and unicast transmissions making suitable for cloud-based services like AWS and Azure. NDI can run on bit or bit CPU architectures, although performance is increased when using bit. The NDI stream itself is formed at the stream consumption end via the platform-specific NDI HX driver, presenting the same uncompressed data to the application software consuming the NDI source regardless of original HX source hardware and compression.

Turn a Raspberry Pi Into an AirPlay Receiver for Streaming Music in Your Living Room

This takes advantage of the hardware TCP acceleration in silicon which helps lower-spec processors handle heavy network load, in contrast to UDP which does not benefit from the hardware acceleration. NDI supports arbitrary metadata as XML blocks, embedded in video and audio frames, as well as stand-alone metadata frames. The content of these metadata blocks form 3 families.
