need help with link to mp3-file

I want to download the second stream on this site:

Code:

http://www.kulturradio.de/programm/literatur/walter_serner_preis1/walter_serner_preis0.html

I figured out the following direct url but net transport says it's larger than two gigs which can't be true for 21 minutes audio:

Code:

rtmp://stream5.rbb-online.de/kul/flash/programm/kulturtermin/2011/kulturtermin_0478.mp3

So what's the right url?

Use this:

Code:

rtmpdump -r "rtmp://stream5.rbb-online.de/kul" -a "kul" -y "mp3:/programm/kulturtermin/2011/kulturtermin_0478" -o kulturtermin_0478.flv

thanks, Bahman :)
But why should I save the file with *.flv-extension?
Isn't it a normal mp3 file?

Isn't it possible to extract the mp3-audio from the flv-file in a lossless way?

Re: need help with link to mp3-file

We are talking about mp3 audio, not wave or m4a or flac or aif or ...!!!
if you convert this flv file to a mp3 file with the same values, in fact it's like you have extracted audio file with out any changes!! before converting it, notice at this values to set in output file:
Bit rate mode : Constant (CBR)
Bit rate : 128 Kbps
Channel(s) : 2 channels
Sampling rate : 44.1 KHz

then convert it!!;)

Re: need help with link to mp3-file

You can do with any software that you want!! there is not any great difference between them!! I use "Jet Audio" for converting files!! It's good!! if you set those values for output file in every softwares, you will get a same mp3 file!! "There is no difference in converting by each software!!"
then, the original flash video file is not a joint stereo!!

May I ask, Why is it so important for you to keep that mp3 untouched?:confused:
