Over this past weekend I discovered a way to execute flash (swf) via the Series 4 RPC protocol. i.e. Execute an arbitrary flash (swf) url such as: Code: http://www.bbc.co.uk/science/humanbody/sleep/sheep/reaction_version5.swf Note that with the above flash example I was able to get Premiere to respond to left/right/select remote presses so looks at least some rudimentary remote control input seems to be possible. NOTE: This works whether using SDUI or HDUI. I know very little about flash programming but exploring a little more I made a simple "Hello World!" ActionScript 2 script and compiled to swf with the free mtasc compiler and served up the resulting swf to my Premiere via a simple Python web server and verified that it ran. Don't know if a fully custom flash application responding to various remote control presses is possible and if for example serving up video through flash would be possible as well. Above simple "Hello World!" script is as far as I got. I tried to do a little with event listeners to see if I could figure out how to capture remote control presses but didn't get anywhere with that. At any rate I thought this was at least mildly interesting and figured I would post here to see if anyone perhaps with more flash experience has an interest in exploring this further. I can post some code for someone to get going on this and replicate what I have done so far if there is any interest.
