Ok, thanks for everything ! It seems to work now, but I will test it better in few time !
So, for someone who want to do the same thing, I’m there :
- Devolay 1.2.0 (https://github.com/WalkerKnapp/devolay/releases): ok with processing (java 8)
- NDI runtime (https://ndi.tv/sdk/): ok but only for Mac OS X 10.15 (Catalina) … I had to upgrade my OS for that… it’s the first time on my artist life that upgraded OS X is favorable
