Ndi source as input

kencee · March 22, 2020, 7:19pm

Hi! I have a question: how can i put an NDI source to be in CasparCG Client list? I have an NDI source from a laptop and i need to show in list. Can i do this? I can use different frame rate like the videos? Can u write what can i do for this? Thank u!

Add a custom command (Tools > Other > Custom Command)

Fill the fields like in the image above, where CASPAR is the name/host of the PC and CG is the name of the source. You shoud specify the server-layer in there in addition to selecting the server in the Output panel above that.

Thank u! U can specify what is 1-1?

jcalado · March 22, 2020, 8:22pm

channel-layer

PLAY 1-1 ndi://CASPAR/CG is: play ‘CG’ NDI signal from host ‘CASPAR’ on layer 1 of channel 1

I get this error.

Add quotes to the input path if it has any spaces.

PLAY 1-1 "ndi://ITL/Test Pattern"

noquierouser · March 27, 2020, 6:17am

Or, if that doesn’t work either, try:

PLAY 1-1 [NDI] "ITL (Test Pattern)"

maybe Your sever version was 2.2.0，I had the same problem in 2.2.0 ，then I tried 2.3.0，it’s woked fine.

Hi
Is the input path the same that NDIAnalysis give if you write “NDIAnalysis.exe /find”

lzx1995 · April 9, 2020, 8:53am

I use the ndi studio monitor to identify the name of the ndi source，
the example amcp protocol to add a ndi source is：PLAY 1-1 "ndi://ITL/Test Pattern"
don’t forget thequote. Then,you can see the picture below, substitute the ITL with “LIVEPC”and the Test Pattern with “NVIDIA…”

Looks like you are running an older version.

Mairaj · January 30, 2022, 7:38am

I have CasparCg Srver 2.0.7 & Client 2.0.8 which is latest - is that I need same server / client version?
Secondly, the NDI source is running from another pc not from the same machine where CasparCG is installed I can see the source is working fine in NDI monitor.

didikunz · January 30, 2022, 9:53am

Server 2.0.7 does not support NDI input. Please try 2.2 or 2.3

Mairaj · January 30, 2022, 12:40pm

video layer showing in my Casparcg client is 10, should I use STOP 10-1 and same as in the case Play 10-1? (I am unable to change video layer in custom command)
having below error

hreinnbeck · January 30, 2022, 1:48pm

Its CHANNEL-LAYER so 1-10 (your log output shows PLAY 1-1 though)

Mairaj · January 30, 2022, 2:21pm

still nothing happens, don’t know what is going wrong as the console didn’t give me any error

didikunz · January 31, 2022, 11:55am

Type NDI LIST in Caspars console window and see, if the source is present, and how the actual spelling needs to be.

Mairaj · January 31, 2022, 12:14pm

NDI LIST shows complete set of NDI sources available, but when I want to play it said source currently not available, meanwhile the same source is playing well in vMix & Wirecast (logs below)

Is the media scanner running? If yes you have some firewall issue, that probably also stops NDI.
