Does anyone know of a Macromedia Flash program that will play a streaming HE-AAC file? If not, anyone know of someone who is willing to write one?

You can't really write that kind of functionality with Flash unless Macromedia decides to support it.

Maybe Mpeg 4 systems is an alternative. A nice tool to create Mpeg 4 Systems content is MP4Box from http://gpac.sf.net . The available tools are not that comfortable, like the on for Macromedia Flash, but with a little bit study usable.

I would start with http://gpac.sourceforge.net/tutorial/bifs_intro.htm .
Then I would take a look at http://gpac.sourceforge.net/downloads/gpac...tests-0.2.3.zip .

You can convert simple shapes from swf to mp4 (BIFS) with MP4Box. Actionscript is not supported, but you can use Java script inside mp4.

Alternative you can create simple shapes with the tool from IBM: http://www.alphaworks.ibm.com/tech/tk4mpeg4

With the "IBMToolkitForMpeg4" you can convert wmf to mp4(BIFS). For further use the created mp4 file can be converted to BIFS text with MP4Box -bt yourFile.mp4 . Then you can use the part from the SceneDescription you like.

For playbeck you can use Osmo4. Supported is rtsp streaming.

Thanks for the input!
