I use get-iplayer 2.80 on Ubuntu 12.04 from the ubuntu repository, but
I see that I have flvstreamer 2.1c1 installed and rtmpdump is not
installed.  The comment above suggests that this is not ideal, does
this mean that the packaging on Ubuntu is not ideal and that it should
install rtmpdump and not flvstreamer?
