Sorry but Andrew Scott is right. When BBC started using Flash there was
only Adobe players and so only legal way of playing flash was using an
Adobe authorised system.  The RTMP protocol was Adobe confidential and
proprietary and not published.  It was reverse engineered but any non
Adobe source code for RTMP based in the US had take down notices issued
and IIRC legal proceedings were started. Reverse engineered players were
still available outside the US.  I'm not sure of the timing but possibly
a year or two after BBC started using Flash , Adobe changed their minds
(possibly because of Apple and iPhone not allowing Flash)  published the
RTMP protocol so 3rd party players could be made available legally.
However , breaking Adobe encrypted RTMP (RTMPE) was/is still illegal.

Again IIRC, once the RTMP protocol was in the public domain and no
threat of law suits, it became feasible to do a Flash based plugin.

In summary, when BBC designed and then implemented their Flash based
Iplayer, they did not think there could be 3rd party players as Adobe
was actively protecting their protocols. 

>From a BBC point of view,  Flash is heavyweight protocol whereas
chunked/HTTP (HLS/HDS,DASH) is lightweight and requires less server
processing (and more modern encryption support) and so longer term Flash
needed to be phased out.
