YOu have to pull frame data out of nsv container and put it in flv container, and you need to parse the aac data to get time-span values for the frames. Then you need to serialize the flv data to rtmp packets. After that then you can create a rtmp port in haxe for flash player to connect to and after the flash player requests the stream, begin sending the data.
