FMS: Smart Pause Feature

Flash Media Server 3.0 includes a Smart Pause feature. This feature allows Flash Player 9 Updater 3 ( to continue to buffer content while pausing the stream without clearing the buffer. Previous versions of the player would clear the buffer when resuming from a pause event (NetStream.pause()) -- causing rebuffering which could lead to latency and unfavorable playback. Smart Buffer does not send the pause event to FMS until the Flash Player buffer limit is reached. The buffer limit (NetStream.bufferLength) is the greater of 60 secs or NetStream.bufferTime. Smart Pause in FMS 3.0 is also backwards compatible with NetSteam.pause() in AS 2.0.

Smart Pause can help to alleviate some of the latency previously experienced when pausing in previous versions of FMS and Flash Player. See TechNote kb403029 for more details. Since the NetStream.pause() is not immediately sent to FMS, some of your FMSIS authorization adaptors E_PAUSE events may not fire. See TechNote kb403040 for more details.
