It’s an open-source single-board computer. It can run Android 4.4, Ubuntu, Debian, Raspbian Image. It uses the AllWinner H3 SoC, and has 1GB DDR3 SDRAM.
The software is the same as The Raspberry Pi.
rpi.ndll will not give you a player for your swf. Nor will haxe. As already explained It can only embed the swf and use the assets - movieclips and graphics - within some limitations described here: http://www.openfl.org/learn/tutorials/using-swf-assets/ (Creating SWF Content section).
I’m not absolutely sure, but it would not surprise me if the rpi.ndll library is meant for specific Pi hardware and GPIO interfaces. But I’m very unsure about that. I’m pretty sure you are not going to run the swf on the Pi though.!
Sorry to disappoint you!
Still out of curiosity
A. Is the swf interactive? (Does it require user input (keyboard, mouse))
B. Does it contain ActionScript.?
If the answers are: A. No, B. No. Then you can convert it to a movie and play it in a regular movie player on your Pi. Otherwise you are probably out of luck!
