I'm on Ubuntu Server 16, and I've compiled it with the SDK and installed the libraries but it doesn't pick up external feeds or anything it encodes not detectable by the network. Anyone got it working successfully?

I was not aware it was already possible... Any link about this? I'd like to see if it's available for windows yet. I can't find any announcement about this on FFMPEG website... Thanks Guillaume

Patchnotes are here, release is here, and they've updated their devices page with the additions. Let me know how you get on. Sim...

I guess you thought about this when compiling : Quote: To enable this input device, you need the NDI SDK and you need to configure with the appropriate --extra-cflags and --extra-ldflags I will try asap Guillaume

Apparently he hasn't added the libs for NDI in it. I just contacted him via Twitter to get more info about his plan about it. Guillaume

What flavor linux you running on? Do you have libavahi-common & libavahi-client installed?

Ubuntu 16.04.3 LTS Quote: Do you have libavahi-common & libavahi-client installed? Yes. After emailing the user list I got an answer that solved it - I didn't have the avahi-daemon installed! Once I got that running everything worked perfectly.

Don't know about what the FFMPEG implementation includes, but the NDI libraries are not available on ARM architecture for video input, only for video output (see how there are NDI phone camera implementations, but no NDI monitoring)

That would be awesome... As a point of reference, earlier this year we created an NDI Camera app for Raspberry PI 3, using the RPi Camera module. Our experience showed that the ARM CPU was not capable of encoding NDI at 1080p but was almost able to manage 720p. This was quite a while ago, so its possible the NDI v3 library is a bit faster but just to prepare you that the Arm Cortex A53 in the PI isn't really fast enough for full HD encoding. This may improve if NewTek are able to optimise NDI for ARM, fingers crossed.

It would have the same issue with the encoding as you would be Transcoding from NDI to MP4 to display on the monitor. Obviously if we could use the GPU somehow that would make it more possible. Last but not least have you seen this product, https://auvidea.com/b101...csi-2-bridge-15-pin-fpc/ This would allow you to convert the camera port to an HDMI input. There are several different models of this product. Thanks for this update as I said it is AWESOME!!! Rich Shumaker

We might create a 'compatible' NDI Video Monitor for windows, if the older NewTek version is not available any more. Beelink AP34 Read more about the BeeLink in the Sienna.cloud blog

I forgot they have not released the NDI SDK for Output on ARM CPUs. That is great news about low cost Win10 boxes using NDI monitor. Have you tried vMix free on that box(SD), or vMix HD Basic? Lastly what type of CPU on Win10 worked meaning what type of CPU onboard graphics chips worked? Clearly an Android Player would be cool as that would open up a LOT of possibilities. All of this is great news for me as it brings things closer to reality everyday. Anyone know of a VST or other plug in for NDI audio yet? Thanks everyone for all this great news. Rich Shumaker

Rich Shumaker The Beelink AP34 uses an Apollo Lake CPU which is basically the newest generation intel ATOM type processor. It don't think it would be any good for VMIx. On the topic of Audio - we are working on integrating NDI and AES67 audio in our new NDI SmartProcessing Router - which is designed as an infrastructure product for building next generation broadcast and post production facilities.

I tested : List input devices: ffmpeg -f libndi_newtek -find_sources 1 -i dummy and Restream to NDI: ffmpeg -f libndi_newtek -i "DEV-5.INTERNAL.M1STEREO.TV (NDI_SOURCE_NAME_1)" -f libndi_newtek -y NDI_SOURCE_NAME_2 Unrecognized option 'find_sources'. Error splitting the argument list: Option not found Apparently windows version does not include libndi_newtek ! How to compile ffmpeg with libndi (for windows) with MSYS+MinGW or cross under linux ? https://trac.ffmpeg.org/wiki/CompilationGuide Under ubuntu does ffmpeg include libndi_newtek ? Thanks
