Printing rtmpdump compatible URLs (radio and live TV)

[Bastien Nocera]

Heya,

I've been working on porting some portions of get_iplayer to quvi so
that I can integrate into GNOME applications, such as GNOME Videos.

The script for quvi 0.9 is here:
https://github.com/grilofw/grilo-lua-sources/blob/master/quvi/bbc.lua

The problem I'm facing is when I attempted to add support for radio and
live sources. I've been using this patch for get_iplayer:

and comparing results of my script with that of my script using this
page:

I'm guessing that my generation of an RTMPdump URL is incorrect (I can't
play the resulting URL when using radio or LiveTV) and would be grateful
if somebody could point out what I'm doing wrong, or even better,
integrate this sort of functionality directly in get_iplayer.

Cheers
