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. ------------------------------------------------------------------------ bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=53229 _______________________________________________ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins
