Mormon Radio - In Latin!

Mormon radio is available at

Sadly, the media transport is RTMPT, a proprietary adobe format, which limits reception to those with an adobe flash plugin. That also means x86 PC architecture.

This excludes all streaming audio devices in the world except Adobe Flash. Oh - and there will be iPhone support soon.

How can this seem nearly OK? There are loads of widely supported mechanisms for streaming audio - why choose one with such limited support? This is like publishing the bible only in Latin - because everyone speaks Latin - or at least everybody who needs to read the Bible speaks latin. And what's so special about the iPhone that cuts out my streaming radio?

Vatican radio on the other hand does it quite well:

It supports wma, real (and mp3 in the left column) and no need for any freaky platform-restricted plugins.

So, I'm a church member and I can wake up to Vatican Radio, but not Mormon Radio - why, exactly?

Someone has to make an active decision and sign a large purchase order to do things as wrong as this.

However, by standing on the shoulders of advocates of software freedom, using wireshark to look at the network packets and recognize RTMP as the protocol, swfmill to take to pieces the flash radio player to get the audio addresses, and flvstreamer to dump the audio, I managed to cobble together a system that allows the stream to be converted into an MP3 stream so that mp3 players can pick it up. I've called this the Wycliffe hack in commemoration of John Wycliffe who strove to make religious material available to everyone.

flvstreamer/flvstreamer_x86 -v -r rtmpt:// -s> -p -o /dev/stdout > RADIO.flv

Of course I don't want to dump to a file called RADIO.flv, I want to convert the stream to mp3, but commands like this work:

cat RADIO.flv | ffmpeg -f flv -i - -f wav -

if they read from flvstreamer stdout, they fail!

So while I've solved the hardest problem, I need to sort out the glue.
