Vorbis dev - Oct 2008 - Flash Vorbis player

Hi,

I wanted to let you know that I have just made available the sources
to the ogg + vorbis implementation in haXe, which I've been working on
for last couple of weeks. The code compiles to an swf file playable in
Flash Player 10.

A demo of a simple player implementation (latest Flash 10 required):

http://people.xiph.org/~arek/pg/hx/test.html

and the sources, in a bzr branch, currently at:

http://people.xiph.org/~arek/bzr/fogg.dev

The code is based on Cortado's JOrbis, hence the license is LGPL.

There are still some issues, as you will probably notice if you try
the demo, but the performance seems promising - just using the new
flash.Vector type from Flash 10, seems to make it ~4 times faster than
a version using the old Array type.

Hopefully now more people will be able to look at the source and
improve it further.

Any feedback will be greatly appreciated, I really do hope we can make
it usable outside of our community.

Hi Arek,

that looks great, at least the performance is much better than with my 
AS3 approach for Flash 9. The sources are however not available on the 
link you mentioned. If you have any interest in releasing your player 
under a less restricted license (Mozilla PL), I would be happy to share 
my AS3 Vorbis decoder with you. Perhaps it's enough to replace the 
arrays I've been using with the new vector to achieve a similar 
performance boost with my code, although the Flash 10 player seem to 
generally execute AS slightly faster. I don't have much time at the 
moment to play around with it myself, but could of course give you a 
helping hand if you need.

Hello Arek!

Nice work, performance is still much worse than the C vorbis decoder,
but I would say it's acceptable and it's good enough for most
applications. I will try it out and most likely use it when
Flashplayer 10 will be released.

Have the Fluendo guys modified the Jorbis lib or is it still the same
Jorbis you can download from jcraft.com?

I wonder why MPL should be better than LGPL. MPL is not compatible to
the GPL 2 and LGPL is fine for most projects as long as you use fvorbis
as a library.

If you really try to put it under a less restrictive license I would
aim for a BSD-style license, that is what xiph is using for ogg and
vorbis.

Hey everyone, I saw over on the Vorbis-Dev list that they ported Ogg  
Vorbis over to Flash.  Just wondering if this would be possible for  
Speex, and also if you have considered an iPhone implementation.  I  
know that Apple is really hesitant to anger AT&T, but with Google's  
Android, VOIP on cell phones is just around the corner.  Ironically  
voice bandwidth is set to go way down because of it, so I never could  
understand why cell phone companies were so resistant to it.  And  
Adobe just ported Flash to the iPhone so that's just around the corner  
too.  Here is the message:

Now it makes sense :-). I'm always for Apache, BSD, MIT, X11 and
similar licenses. And I share your view about the LGPL. Should we ask
the author of Jorbis what he is thinking about it? I'm sure he is on
this mailing list anyway. Nevertheless I wouldn't worry too much about
the LGPL, it's still quite a liberal license.

I reckon Flash 10 has native Speex support, so that should be enough
for everyone(?).

Arek, does this read the Vorbis bytes on the server or the client?
That is, it it transcoding from native vorbis to native swf as part of
generating the flash, or is the Flash in the browser opening the
Vorbis?

Vorbis is decoded by Flash on the client. No transcoding involved.

That is completely amazing.  Completely and totally 100% frakkin
amazing.  Arek, you are a hacker god.

The ability to deploy new formats in the browser with nothing but
web-borne code is huge breakthrough.
