I'm one of the developers of Moyea FLV Converter SDK.
Why we charge $2000 per copy is that, it's not just an flv to mp3 tool, it's a tool for converting flv to other video formats, like AVI/MPEG/WMV/MOV/MP4/3GP.
And we know it's quite expensive for the application which just wants to extract the audio from flv, so we have developed another tool named Moyea FLV Audio Converter SDK, you can get a trial from http://www.flvsoft.com/flv_to_mp3_sdk/
It runs on Windows, and the linux version is planning.

I don't think the Windows version is very useful for anybody but single users, and they wouldn't want to pay $800 for it anyway. Let's see a Linux version that can run as a script on a server, and that will be somewhat more interesting ;)

Another bid for a Linux version that runs as a script. $1000.

I will see your $1,000 and raise you $500.
I'l gladly pay $1,500 for a RELIABLE Linux based conversion apparatus.
I'd even be willing to pay good money for a reliable web services based remote solution.

I think $1,500 is a bit excessive, not everybody's flush with cash. I think at under $1000 it would be much more accessible, and the developer would be able to make more money that way :)

I agree 100%. $1,500 is excessive especially for a utility that I think Adobe should provide to us. But having the solution would enable our podcasting efforts to grow by an order of magnitude and if I take all the time and money I've spent screwing around with Windows solutions I'd be able to spend $1,500 and have enough left over for a trip to Paris.
Your point is well taken. Hopefully a competent developer with the skills and competencies will seize the opportunity .

Why you hate Windows so badly ?
Do you have any bad encounter with Windows?
I want to know if the bad encounter was caused by Windows or the bad software you had ever used ...

No -- it's just because it's not the best platform for servers, I find. Most of us run Linux+Apache+MySQL+PHP (LAMP) (or BSD, etc), and they are much better suited for back-end processing.
Mind, Windows is also simply MUCH more expensive as a server solution.

Hi,
does anybody have the flv2mp3 tool downloaded? The links which are provided here doesn't work no more and I did'nt find any other site where I can download the tool. Yould be nice if somebody could send me the tool.

Hey guys, I took up your challenge. You can download a Linux NellyMoser FLV conversion tool (which will run on a server) called 'nellynomore' here:
http://www.thoughtcrime.org/software.html
...let me know if anyone has any problems with it.

I got some feedback from some folks who tested out my flv conversion tool, fixed some bugs, and made some optimizations. There's now a 0.3 version available at the same site (nellynomore).
This new version will give a 4x transcoding speed increase for folks who are using 8khz encoded audio (which is what comes from the flash plugin when you hook the microphone up to a netstream), and a 2x transcoding speed increase for folks who have FLVs encoded with a 22khz sample rate.

Any ideas?

About the SDK, how long does it take to process the transcoding? What's the ratio like?

It does asap (As Soon As Possible) conversion, which depends on your system performance, on XP SP2 with AMD64 Dual core CPU, it takes 50% of the CPU usage (because the conversion is single threaded and the cpu has two cores), and the speed reaches 26X, an hour long flv needs 2 minutes 30 seconds to transcode from nellymoser audio to 96kbps mp3

That's assuming only one transcoding is running at a time... right? How do the numbers work out, let's say, when running 50 or so concurrent transcodings?

I got more feedback from people trying to use my FLV conversion tool, and have put up another new version (0.4). This fixes problems people were having with a segfault when libflashplugin.so was not specified with an explicit path, and problems people were having encoding FLVs with an audio length of more than 24 seconds.
jaycharles, to answer your question about running many parallel transcodings, with the Moyea tool that won't work so well. Any time you introduce more processes that use ~100% of your CPU time than the number of CPUs you have (in the case of a core-2 duo, more than two processes) , you're just introducing a heavy amount of context switching that will severely degrade the performance of each process. The high-performance solution is to write a server that queues your conversion requests and runs them in series on as many threads as there are CPUs on the machine, but never more. The best model I know of for this is the standard HPSA asynchronous work queue.
This isn't really possible to architect in something like PHP, so you'd have to hand off your conversions to an external process. On the other hand, my FLV conversion tool is slower, but is not nearly as CPU intensive. You could probably get away with running 50 concurrent transcodings without seeing a degradation in performance, it's possible that the overall conversion time for all 50 might approach what would happen if you tried to run 50 Moyea processes concurrently.
