Hey all!
I published https://github.com/Dimous/linc_ffmpeg
Utility wrapper for linc_ffmpeg is not production ready and I have no time to debug and test it on other platforms. Sorry for failing your expectations.
To AIR folks I would recommend to use NME (the father of OpenFL) (sorry, Joshua 
) because it implements Flash APIs in cpp (I mean – native-first). As far as I remember, I compiled https://github.com/haxenme/nme/tree/master/samples/Camera and https://github.com/haxenme/nme/tree/master/samples/StageVideo for Windows & Android and it worked. And if it doesn’t, you should file a bug. It is still maintained (by the author of hxcpp, btw).
