I can get AAC music to play using video approach, but I have to continue a runtime error:
_ Error: Error #2030: End of file was encountered.
I am unsure if this error can only be removed by using the FMS, or if it is a bug in flash, or down to something strange like where the XML is stored in the AAC. The error seems to be inside the NetStream class, maybe there is another way to approach this, I maybe missing a step.. but you will see the code does play the track, so I am not far off.
I used iTunes to convert a friends salsa mix to an AAC format maybe it's down to the AAC used (ie maybe I need to convert with a different package)?
Anyway its in haXe but very similar to flash so any flashers should follow it easily. I have enclosed instructions for any first time haxe users.
To test use haxe auto installer (win,mac,linux)
_http://haxe.org/file/hxinst-win.exe _http://haxe.org/file/hxinst.dmg _http://haxe.org/file/hxinst-linux.tgz
Then run the compile script from terminal from where you create the two files.
_ haxe AACtest.hxml
you will need an AAC music track called
_ showMusic.m4a
then just run in flash
