I'm trying to download this programme:

Hello Chris :-)
Actually, I'm seeing many similarities with BBC iPlayerRadio...
1. When you click the purple "Listen" button, a new popup opens:
http://www.rte.ie/radio/utils/radioplayer/rteradioweb.html#!rii=16%3A10365453%3A0%3A%3A
2. Go to:
http://meyerweb.com/eric/tools/dencoder/
and decode the last string of previous URL:
16%3A10365453%3A0%3A%3A => 16:10365453:0::
The pid of your show is (initial URL):
clipid=1785754
The "version PID" is the 8 character string after the first colon
inside the decoded string, i.e.
vPID=10365453
This vPID can be used to get access to stream data.
3. If you parse manually the page source of the opened popup,
you'll find a "mediaselector API" equivalent in the form of:
http://www.rte.ie/rteavgen/getplaylist/?type=web&format=jsonp&id=
which produces a JSON file with stream info, if you append your
previously found vPID:
http://www.rte.ie/rteavgen/getplaylist/?type=web&format=jsonp&id=10365453
(file is attached).
You can manually construct the rtmpdump command for download:
rtmpdump -r "rtmpe://fmsod.rte.ie:1935/" -a "rtevod" -f "WIN 16,0,0,305" -W
"http://www.rte.ie/static/radio/radioplayer/rteradioweb_70_osmf.swf"; -p

Remux losslessly with FFmpeg:
ffmpeg -i "foo.flv" -vn -c:a copy -bsf:a aac_adtstoasc -f ipod "foo.m4a"
End file is a HE-AACv1, 44.1kHz, ~ 64kbps,
which would be a "flashaac" radiomode.
In the JSON file there's also info for the HLS stream;
the HLS playlist URL is:
https://vodhls.rasset.ie/manifest/audio/2015/0123/20150123_rtelyricfm-thelyricfeature-thelyricfe_cl10365453_10367847_261_.m3u8

ffmpeg -i

However, this takes much longer than the RTMPdump way.
End file would be the equivalent of a "hlsaac" radiomode!

There you have it!
I bet somebody with (lots) of extra time and coding skills
could write a RTE.pm plugin for get_iplayer (all the
helper apps are already existing) or even a standalone
script...
Regards.
