I would like to know if FFMpeg is supporting dynamic streaming for RTMP
streams similar to JW player.

In addition to loading a single RTMP stream, JW Player 6 supports loading *
dynamic* streams. A dynamic stream consists of multiple single streams of
the same content, all in a different quality. The JW Player allows
automated or manual switching between the different qualities in such a

Dynamic streams have to be set up using so-called SMIL manifests. These are
simple XML files that contain the location of the RTMP application, plus
the path to (one or more) streams stored on the RTMP server. The player
always presume a file with the extension *.smil* is an RTMP SMIL manifest:
