In the vMix call I did last night there were a few annoying issues. Just for reference I was the host in Columbia, South Carolina. My 2 guest were in San Diego California. My audio and video were perfect. I'm on a fiber line which is running a little slow right now, it's at about 350mb up and down. It's usually between 500 and 800 up and down. My audio and video (the host) was perfect throughout the whole hour long show. My guest had intermittent audio crackling, stuttering if you will. and some infrequent video stutters but very few. I in my limited network experience can't figure it out. I di run this test this morning on https://test.webrtc.org/. Unfortunately I can't interpret the results, what they tell me, if any thing can be done and if so what? maybe someone here can help?
