I&#x27;m curious why Facebook was willing to sacrifice delivering adaptive stream to get better latency. I guess they explain that for &quot;Live for People,&quot; it makes more sense to have less latency through RTMP, as opposed to possibly worse video or connection. However, I know Periscope is using HLS for all of their stream, save for Android where it looks like RTSP.<p>Anyone have any thoughts or insights on Facebook&#x27;s decision to use RTMP as opposed to HLS?
