Did you get anywhere with this. I am able to stream with OBS just fine, but I dont know how to add the "streamkey" portion which is actually the username not the streamkey. The streamkey for dlive is given as a url argument like this: rtmp://stream.dlive.io/live?key=zr7MVllUEc9KQlw2_Y_2YADDAYADDAYADDwBJ4IomMSQ0=
I discovered that the "Streamkey" field in OBS comes across as "name" but changing the PUSH url to rtmp://stream.dlive.io/live?key=zr7MVllUEc9KQlw2_Y_2YADDAYADDAYADDwBJ4IomMSQ0=&name=USERNAMEHERE had no effect and dlive still rejects the connection.
