I have an AIR app I built that lets you record sound and then save the sound to the desktop as an FLV, WAV, or MP3 file.
It's quite primitive right now, and is working better on Windows than on the Mac (although I develop on a Mac).
I am posting about it here simply because I thought those involved in this topic may find it interesting. The app is pretty simple and should be self-explanatory.
It can be downloaded here:

For some reason in the previous posting, it adds a space at the end of the URL I posted. The appNumber should be 177, not 17 7

I have created a Linux based converter that works as a simple command-line tool.
flv2wav infile.flv outfile.wav
I've only ran it on a Gentoo VM. It takes around 1 second to convert 300 seconds (5mins) of FLV to WAV. So it's very fast.
There's still some work I want to get done on it before it's ready for my uses (for instance ensuring compatibility with FLV's generated by FlashMediaServer, Red 5, aswell as my own high-performance Linux MediaServer).

That looks pretty cool, I wonder if that could be used to communicate with Flash Media Server? How do you uh, work with AIR Apps?

(the [] represents time, as you can see it takes only 33milliseconds to convert a 30 second FLV to WAV, so it's effectively instant) My server specs are:

Also doesnt depend on other packages like X etc, firefox etc.

jaycharles: It doesn't use flashplayer. I'm not in the process of selling it, and I'd probably just give it away for free. At the moment I'm interested in other people's thoughts, what features they're looking for, and whether they could provide me with FLV's that they're trying to convert, and I'll add such functionality into the converter.
There's quite a bit of math involved in decoding FLV's and generating the PCM output, I want to make sure it's top notch before releasing it. That was the only reason for supplying my gmail.

Thanks for clarifying that for me. We've had a number of postings for similar software here that people either wanted money for, or that used questionable methods for handling the transcoding, neither of which are appropriate for the fourm.

Here's a link to an open source Nellymoser Asao decoder:

OMG. Whoever you is, you done it. I don't know who wrote this, but they must obviously be concerned with the legality, as the copyright authors' names are md5()'d. :) Anyway, great work, whoever you are!!!
Timing:
[root@defiant nelly2pcm]# time ./nelly2pcm test.flv > test.pcm
mono Nellymoser stream with 16-bit samples at 22kHz
real 0m1.212s
user 0m0.702s
sys 0m0.058s
For a 90-second .FLV.
Total time to run the following:
time ./nelly2pcm test.flv > test.pcm
sox -t raw -c 1 -w -r 22000 -s test.pcm test.wav
lame test.wav test.mp3
real 0m3.551s
user 0m3.426s
sys 0m0.088s
This is on a dual Opteron.
Hats off.

Is it possible to decode stream ? in the real time ? to accomplish connection with the Asterisk for example ?

Woo hoo! This one works perfect for me. I can't tell you all the different "decoders" I have tried. Some worked, but the audio was crap since it was trying to record at a faster speed than on the fly. Others just didn't work at all. Many Thanks!

Hehe, that'd be the next cool thing to do, but I think we're far from that. The only POSSIBILITY I can even think of is using Red5, since it runs on Java, and adding some classes that link it to Asterisk - if it's possible at all.

Hi,
I've been reading this forum for a while as this is a problem I'm really interested in solving legally - i.e. without having to recommend using tools that might break the Flash Player EULA.
Would this Open Source codec pose any legal problems for use as part of a software solution...or am I opening a can of worms asking that question? :)

Since we don't seem to have any attorneys or patent researchers here, I don't think we have a solid answer to that question.
Given that there are no commercially available alternatives to the Asao codec (or at least, none from verifiable, reputable sources), I personally would think twice about using it, especially in a commercial application.
Ask yourself this... if there is a free, legal alternative, why on earth would adobe pay to license the codec?
I do, however, find the MD5'd copyright notice absolutely hysterical.

Hi all,
I am glad too that someone wrote such an easy to use decoder (flv2pcm), however, as a lot of ppl I am worrying about legal issues.
After a bit more than 3 weeks, does anybody have any informations about that ?
ie: Is it legal to use this tool, if not, what can I do to use it legally ?
Thanks to all, in particular for this unknown soldier who wrote that :)
