Vorbis dev - Oct 2008 - Flash/Vorbis: Even more improvements

Hello everyone,

the code is slowly getting a little bit messy, but at least I've managed 
to tweak a lot of performance out of my Vorbis player for Flash. I did 
several improvements to the Huffman decoder by eliminating function 
calls and managed after a while to create an AS/haXe hybrid player. The 
haXe compiler definately produces much more efficient bytecode (at least 
in some situations) and the iMDCT function is 2.5-3 faster compiled with 
haXe, compared to the code generated by the Adobe compiler. If someone 
knows how to generate an SWC library from the haXe code, I would 
appreciate some help a lot. At the moment, the haXe code is dynamically 
linked into the AS application at runtime.

Overall, the CPU load is getting very acceptable:

Big difference! Very nice!

I don't know how to create an SWC from haxe, maybe ask on the haxe mailing
list.

You could try to translate haxe to AS3 with haxe. Generate a SWC lib
with the Adobe software. Unpack the swc file with unzip, replace the
AS3 swf with the haxe swf and zip it back to swc. No idea, if that
really works.
