No audio from NDI source generated by NewTek TriCaster #723

in OBS Studio select an NDI Source generated by TriCaster and Viz Vectar version 7.5 or above (NDI 5) OBS recieve correctly the video but there is no audio

Both TriCaster and Vectar generate an NDI Output with 16 audio channels this is probably the reason why OBS do not recognise the audio format

Related to https://github.com/obs-ndi/obs-ndi/issues/622 @Trouffman Which to keep?

Trouffman commented 2 months ago

Let's keep this one. This is identified as a hard limit set to 8 in the codebase.

https://github.com/obs-ndi/obs-ndi/blob/04ec2ca44202fd7b884f95d81829ba1c616c9dc9/src/obs-ndi-source.cpp#L785C27-L788

According to the documentation : no_channels (int) This is the number of discrete audio channels. 1 represents MONO audio, 2 represents STEREO, and so on. There is no reasonable limit on the number of allowed audio channels.

Reason for hard-limit : This was hard-set back in 2020 because the 16 channels was carshing OBS. : https://github.com/obs-ndi/obs-ndi/pull/518

@Rob-NDI We have no way to get this tested / reproduced with the Vizrt hardware. If this came from customer support on your side, can you report back if it works (when fixed). - If you cannot report back on it, very unlikely this is fixed unless we have a way to test as this will need to be tested to be "commited".

Hi @Trouffman Just tested and it works great

if you want to have an NDI source with 16 audio channels you can use this application: https://kanelp7.wixsite.com/kanesworld/ndi-signal-generator

have a great day
