remoteJoined2SetView property

If the local user calls startMediaRenderingTracing before the remote user joins the channel, this value is the time interval (ms) from when the remote user joins the channel to when the local user sets the remote view. If the local user calls startMediaRenderingTracing after the remote user joins the channel, this value is the time interval (ms) from calling startMediaRenderingTracing to setting the remote view. If the local user calls startMediaRenderingTracing after setting the remote view, the value is 0 and has no effect. In order to reduce the time of rendering the first frame for remote users, Agora recommends that the local user sets the remote view before the remote user joins the channel, or sets the remote view immediately after the remote user joins the channel to reduce this value.
