I did do a restart. The PC that is acting as the server has an Intel processor with the Quicksync disabled (on the CPU or by the driver i’m not sure). I’ve observed that installing the avc pack and forcing the codec to H.264 in the preferences caused it to fallback to VP8. I don’t know why the behavior is not reproducible for you. In any case, It works now when I leave the settings alone after installing and i’m happy with it.
