I think the pid p00mlvd0 refers to the stream for the programme
"version" in get_iplayer parlance (default, audiodescribed, signed). It
might apply more generally in identifying multiple items in an iPlayer
playlist resource. At any rate, it is part of the identifier for the
specific media stream that the flash player is accessing, which is why
you see that value when you right click on the player. get_iplayer is
coded to start one level up with the metadata describing the programme
or episode itself, from which it then ferrets out the identifiers for
the "versions" and turns them into URLs for the individual streams
corresponding to the available modes. So in this case, pid p00mlvcy
refers to the iPlayer programme resource itself. To find it, you select
"View Source" for the page of interest and look for where the flash
player is set up. In this case, you would see the following code:
var emp1 = new bbc.Emp();
You can see the pid for the programme in the playlist URL. Of course,
in this case it is a playlist with only one entry, for the Coldplay
video. If you put that playlist URL into your browser, it will return
the XML definition for the playlist, where you can see the <item>
element has an "identifier" attribute with the value p00mlvd0. This is
the metadata that get_iplayer processes to find the available media streams.
Bottom line: for get_iplayer you need the pid (referring to the iPlayer
programme resource) that is fed to the flash player by the enclosing web
page, not the pid used to identify the stream that the flash player
eventually connects to. Clear as mud, eh?
