Flash/RTMP Subscriber


The Red5 Pro HTML SDK Flash-based Subscriber embeds a SWF file - utilizing swfobject - to incorporate playback over RTMP.

The Red5 Pro HTML SDK supports the following SWF integration:

  • A bare-bones RTMP playback viewer - included in the src directory as red5pro-subscriber.swf - and distributed with the live webapp of the Red5 Pro Server install.

    • Note: You will need to provide a URL to the swfobject library which will be dynamically injected at runtime if not - by default - found relative to the page at lib/swfobject.
